The September 11 attacks, often referred to as 9/11, were a series of coordinated terrorist acts that took place on September 11, 2001, in the United States. Nineteen members of the extremist group al-Qaeda hijacked four commercial airplanes. Two of these planes were flown into the Twin Towers of the World Trade Center in New York City, causing the towers to collapse, while a third plane crashed into the Pentagon near Washington, D.C. The fourth plane, United Airlines Flight 93, crashed into a field in Pennsylvania after passengers bravely attempted to regain control from the hijackers. In total, nearly 3,000 people lost their lives in these attacks, making it one of the deadliest terrorist incidents in world history. The September 11 attacks had profound and far-reaching consequences, leading the United States to launch the War on Terror, including the invasion of Afghanistan to oust the Taliban regime that harbored al-Qaeda, and reshaping global security and geopolitics. The event also resulted in significant changes to U.S. domestic and foreign policies, as well as a heightened focus on counterterrorism efforts worldwide.
The October 7th Attack On Israel

On October 7, 2023, a tragic and devastating attack occurred when Hamas terrorists launched a surprise assault on Israel. The attack resulted in the tragic loss of over 1,400 lives, with innocent people being targeted in their homes, at a music festival, and on the streets. In response to this act of violence, the Israeli government made a firm commitment to dismantle Hamas, the armed Palestinian group that controls the Gaza Strip. Israel initiated a series of extensive airstrikes on Gaza, leading to a significant loss of life, with more than 8,000 casualties reported by the Hamas-run Gaza health ministry. Additionally, Israeli troops were sent into the embattled enclave. The repercussions of this violence have sent shockwaves through the region and the international community.
The Munich Massacre

The Munich massacre of 1972 remains a dark chapter in Olympic history, where the spirit of global unity was brutally shattered. During the Summer Olympics in Munich, West Germany, eight members of the Palestinian militant organization Black September orchestrated a heinous terrorist attack that sent shockwaves across the world. They infiltrated the Olympic Village, resulting in the tragic deaths of two members of the Israeli Olympic team, while taking nine others hostage. The operation was ominously named "Iqrit and Biram" in reference to two Palestinian Christian villages whose residents had been displaced by the Israeli Defense Forces during the 1948 Arab–Israeli War. Luttif Afif, also known as "Issa," served as the Black September commander and negotiator. Shockingly, West German neo-Nazis provided logistical support to the group. The hostage crisis unfolded with a demand for the release of 234 Palestinian prisoners held in Israeli jails, along with Andreas Baader and Ulrike Meinhof, founders of the Red Army Faction, who were imprisoned in West Germany.
In a tragic turn of events, West German police launched an ill-fated rescue attempt, resulting in the deaths of five of the eight Black September members and all of the hostages. A West German policeman also lost his life in the crossfire. The West German government faced intense criticism for the execution of the rescue operation and its handling of the entire incident. Remarkably, the three surviving perpetrators, Adnan Al-Gashey, Jamal Al-Gashey, and Mohammed Safady, were arrested but later released the following month in a hostage exchange prompted by the hijacking of Lufthansa Flight 615.
The 2013 Boston Marathon Bombings

The 2013 Boston Marathon bombings were a horrific terrorist attack that occurred on April 15, 2013, during the annual Boston Marathon in Boston, Massachusetts, United States. Two pressure cooker bombs, placed near the finish line of the race, detonated within moments of each other, resulting in a devastating and chaotic scene. The explosions killed three people and injured hundreds, many of whom suffered severe injuries, including limb amputations. The attack sent shockwaves throughout the nation and the world, as people came together to support the victims and the city of Boston. In the days following the bombings, a massive manhunt ensued, leading to the capture of the two perpetrators, Tamerlan and Dzhokhar Tsarnaev. The Boston Marathon bombings serve as a reminder of the resilience of the people of Boston and the importance of collective strength in the face of adversity, as well as the ongoing need to combat terrorism and protect innocent lives.
McGurk's Bar Bombing

On December 4, 1971, a horrific tragedy unfolded in Belfast, Northern Ireland, when the Ulster Volunteer Force (UVF), a loyalist paramilitary group, carried out a devastating bombing at McGurk's Bar, a gathering place for Irish Catholics and nationalists.
The explosion resulted in the complete collapse of the building, claiming the lives of fifteen innocent Catholic civilians, including two children, and leaving another seventeen wounded. Regrettably, it marked the deadliest attack in Belfast during the Troubles.
Despite clear evidence to the contrary, British security forces initially asserted that the explosion had been caused by a bomb mishandled by members of the Irish Republican Army (IRA) inside the pub, implying that the victims bore some responsibility for the tragedy. Subsequent investigations revealed that the Royal Ulster Constabulary, the police force in Northern Ireland at the time, had shown a bias in favor of this misleading narrative, hindering the pursuit of justice.
The 7/7 London Bombings

The July 7, 2005, London bombings, often referred to as the 7/7 bombings, were a series of coordinated terrorist attacks that occurred in London, United Kingdom. On that fateful day, four suicide bombers targeted the London public transportation system during the morning rush hour. Three bombs exploded on London Underground trains, and one exploded on a double-decker bus. The attacks claimed the lives of 52 people and injured hundreds more. The perpetrators, who were inspired by extremist ideologies, carried out these attacks with the aim of causing mass casualties and instilling fear in the heart of one of the world's major cities. The 7/7 bombings marked one of the deadliest terrorist incidents in the history of the United Kingdom and served as a stark reminder of the enduring threat posed by terrorism in the modern world.
The Birmingham Pub Bombings

The Birmingham pub bombings of November 21, 1974, stand as a grim chapter in the history of terrorism in the United Kingdom. On that fateful day, explosives detonated in two public houses in Birmingham, England, resulting in the tragic loss of 21 lives and leaving 182 others injured.
Although the Provisional Irish Republican Army (IRA) never officially claimed responsibility for the bombings, a former senior member of the organization confessed their involvement in 2014. In 2017, Michael Hayes, one of the alleged perpetrators, asserted that the intention had not been to harm civilians and that their deaths were an unintended consequence of a delayed warning to security services. Following the bombings, six Irishmen were swiftly arrested and subsequently sentenced to life imprisonment in 1975, becoming known as the Birmingham Six. They consistently maintained their innocence, alleging that police had coerced them into signing false confessions through severe physical and psychological abuse.
After 16 years behind bars and a tireless campaign for justice, their convictions were eventually declared unsafe and unsatisfactory, leading to their release by the Court of Appeal in 1991. This tragic episode is widely regarded as one of the most egregious miscarriages of justice in British legal history and represents one of the deadliest acts of the Troubles, as well as the deadliest act of terrorism in England between World War II and the 2005 London bombings.
Pan Am Flight 103

Pan Am Flight 103, known as PA103 or PAA103, was a routine transatlantic flight traveling from Frankfurt to Detroit with stopovers in London and New York City. Tragically, on the evening of December 21, 1988, shortly after 19:00, the aircraft was destroyed by a bomb that had been planted on board while it was in flight over the Scottish town of Lockerbie. The explosion resulted in the loss of all 243 passengers and 16 crew members, a horrific event that became known as the Lockerbie bombing. Large portions of the aircraft crashed into a residential area in Lockerbie, claiming the lives of 11 residents. With a total of 270 fatalities, the Lockerbie bombing stands as one of the deadliest terrorist attacks in the history of the United Kingdom and remains its deadliest aviation disaster ever.
Following a thorough joint investigation by Dumfries and Galloway Constabulary and the US FBI, arrest warrants were issued for two Libyan nationals in November 1991. In 1999, Libyan leader Muammar Gaddafi handed over the two men for trial at Camp Zeist, the Netherlands, after protracted negotiations and UN sanctions.
In 2001, Abdelbaset al-Megrahi, a Libyan intelligence officer, was sentenced to life in prison after being found guilty of 270 counts of murder related to the bombing. In August 2009, he was released by the Scottish government on compassionate grounds due to a diagnosis of prostate cancer, and he passed away in May 2012 as the only individual convicted in connection with the attack.
The January 2016 Iraq attacks

The January 2016 Iraq attacks marked a devastating wave of terrorist violence that struck Baghdad and Miqdadiyah, Iraq, on January 11, 2016. These coordinated attacks resulted in a tragic toll, with 132 lives lost, including the six attackers themselves. The Islamic State of Iraq and the Levant (ISIL) claimed responsibility for these horrific explosions shortly after they occurred, underscoring the ongoing threat posed by extremist groups in the region. These attacks serve as a grim reminder of the challenges Iraq has faced in its efforts to maintain stability and security amid the complex and volatile landscape of the Middle East.
The Dublin and Monaghan Bombings

The Dublin and Monaghan bombings of May 17, 1974, stand as a harrowing chapter in the history of Northern Ireland's Troubles. These coordinated attacks, orchestrated by the Ulster Volunteer Force (UVF), unfolded in counties Dublin and Monaghan, Ireland. Three powerful bombs exploded in Dublin during the evening rush hour, followed by a fourth detonation in Monaghan nearly ninety minutes later. The devastation resulted in the tragic loss of 33 innocent civilians and left almost 300 others injured. This appalling act of violence marked the deadliest attack of the Troubles and stands as the Republic of Ireland's most lethal incident in its history. Tragically, most of the victims were young women, with ages ranging from 19 to 80 years old.
The UVF, a loyalist paramilitary group from Northern Ireland, only claimed responsibility for the bombings in 1993, despite having launched several previous attacks in the Republic since 1969. Notably, the British government had lifted the UVF's proscribed status just a month before the bombings. The attacks occurred during the Ulster Workers' Council strike, a general strike led by hardline loyalists and unionists in Northern Ireland who vehemently opposed the Sunningdale Agreement. This agreement aimed to establish power-sharing between Irish nationalists and unionists in Northern Ireland, as well as a role for the Republic of Ireland in Northern Ireland's governance. The Republic's government played a significant role in bringing about this agreement. Tragically, the strike ultimately led to the downfall of the Sunningdale Agreement and the Northern Ireland Assembly on May 28. Shockingly, to this day, no one has been charged in connection with the Dublin and Monaghan bombings, leaving the wounds of this tragedy still open and unresolved.
The 2015 Beirut Bombings

The 2015 Beirut bombings, occurring on November 12, 2015, were a tragic and devastating act of terrorism that unfolded in Bourj el-Barajneh, a southern suburb of Beirut, Lebanon, primarily inhabited by Shia Muslims. Two suicide bombers detonated explosives in a densely populated area, resulting in the tragic loss of 43 lives, with many more people injured. The Islamic State of Iraq and the Levant (ISIL) claimed responsibility for these attacks, making them the worst terrorist incident in Beirut since the end of the Lebanese Civil War. These bombings occurred just twelve days after the downing of a Russian airliner over the Sinai Peninsula, which killed 224 people, and one day before the coordinated attacks in Paris, France, which claimed the lives of 137 individuals. In response to the Beirut bombings, Lebanese authorities arrested numerous suspects, primarily Syrians, believed to be involved in the attack. The incident underscored the global reach of terrorism and the need for international efforts to combat extremist ideologies and violence.
The Tenerife Airport Disaster

The Tenerife Airport Disaster, which occurred on March 27, 1977, remains one of the most tragic and devastating incidents in aviation history. Two Boeing 747 passenger jets, KLM Flight 4805 and Pan Am Flight 1736, collided on the runway of Los Rodeos Airport, now known as Tenerife North Airport, on the Spanish island of Tenerife. This horrific collision took place as KLM Flight 4805 initiated its takeoff run amidst dense fog while Pan Am Flight 1736 was still on the runway. The collision and ensuing fire resulted in the loss of all lives on board KLM 4805 and the majority of occupants on Pan Am 1736, with just 61 survivors in the front section of the aircraft. This tragic event claimed a total of 583 lives, making it the deadliest aviation accident in history. The circumstances leading to the disaster were exacerbated by a bomb explosion by the Canary Islands Independence Movement at Gran Canaria Airport, diverting numerous flights, including the two involved in the accident, to Los Rodeos. The airport's congestion, limited visibility due to fog, and misunderstandings in radio communications all played a role in this catastrophic event. The subsequent investigation placed primary responsibility on the KLM captain's decision to take off under the mistaken belief that they had received clearance from air traffic control, with KLM ultimately accepting responsibility and agreeing to provide financial compensation to the victims' families.
The Cinema Rex Fire

The Cinema Rex fire, a tragic event that unfolded on August 19, 1978, in Abadan, Iran, left a deep and lasting impact on the country's history. The devastating fire claimed the lives of a significant number of people, with estimates of the death toll ranging from 377 to 470 individuals. The catastrophe was initiated by four Islamic militants who doused the Cinema Rex building with airplane fuel and set it ablaze.
This ruthless attack, one of the largest terrorist acts in history at the time, set off a chain reaction that played a pivotal role in triggering the 1979 Iranian Revolution, resulting in the overthrow of the Iranian monarchy. Initially, the Pahlavi dynasty blamed "Islamic Marxists" for the fire, but later acknowledged the involvement of Islamic militants. Concurrently, anti-Pahlavi protesters, fueled by a climate of mistrust and anger, falsely accused SAVAK, the Iranian secret police, of setting the fire.
The 2023 Peshawar Mosque Bombing

The 2023 Peshawar Mosque Bombing was a tragic incident that occurred in the Police Lines area of Peshawar, Khyber Pakhtunkhwa, Pakistan.
During the solar noon Zuhr prayers, a suicide bomber, dressed in a police uniform and arriving on a motorcycle, managed to bypass multiple police barricades undetected. In a devastating act, he detonated a suicide vest while standing in the first row of worshippers, resulting in a powerful explosion that caused the mosque's roof to collapse. This horrific attack claimed the lives of 101 people and left over 220 others injured. Tragically, 84 of the casualties were police officers, accounting for 90% of the victims.
The Jamaat-ul-Ahrar, a faction of the Tehrik-e-Taliban Pakistan (TTP), claimed responsibility for the bombing, citing it as an act of vengeance for the death of their founder and former leader. The main TTP group later denied involvement but did not comment on the statements made by Jamaat-ul-Ahrar.
The Bologna Massacre

The Bologna massacre, known as the "strage di Bologna" in Italian, remains a haunting chapter in Italy's history. On the morning of August 2, 1980, a terrorist bombing targeted the Bologna Centrale railway station, resulting in the tragic loss of 85 lives and leaving more than 200 people injured. The attack was attributed to members of the neo-fascist terrorist organization Nuclei Armati Rivoluzionari (NAR), although the group vehemently denied involvement. In the aftermath, the city of Bologna witnessed large demonstrations in Piazza Maggiore, its central square, where government representatives who attended the funerals of the victims on August 6 faced harsh criticism. President Sandro Pertini, who arrived in Bologna on the day of the massacre, received the only applause, and he tearfully expressed, "I have no words; we are facing the most criminal enterprise that has ever taken place in Italy." Symbols of the tragedy included the #37 bus, used to transport victims, and the clock, frozen at 10:25, serving as a poignant reminder of the event. The Bologna massacre stands as the worst atrocity in Italy since World War II.
The Air India Flight 182 Bombing

The Air India Flight 182 bombing on June 23, 1985, remains a tragic and pivotal event in aviation and terrorism history. This passenger flight, operating on the Montreal–London–Delhi–Bombay route, disintegrated over the Atlantic Ocean due to a bomb explosion planted by Canadian Sikh terrorists. The aircraft, a Boeing 747-237B registered as VT-EFO, was en route from Montreal to London at an altitude of 31,000 feet when the explosion occurred. The wreckage fell into the sea approximately 190 kilometers off the coast of Ireland, claiming the lives of all 329 people on board, including 268 Canadian citizens, 27 British citizens, and 24 Indian citizens. The bombing of Air India Flight 182 stands as the worst terrorist attack in Canadian history, the deadliest aviation incident in Air India's history, and was the world's deadliest act of aviation terrorism until the September 11 attacks in 2001.
The transnational nature of the plot involved citizens and governments from five different countries. The Babbar Khalsa, a Sikh militant and Khalistani separatist group, was implicated in the bombing.
Despite a lengthy investigation and prosecution lasting almost two decades, only one person, Inderjit Singh Reyat, a dual British-Canadian national, was convicted in 2003 for his role in assembling the bombs that caused the tragedy. The subsequent inquiry revealed a "cascading series of errors" by the Government of Canada, the Royal Canadian Mounted Police (RCMP), and the Canadian Security Intelligence Service (CSIS) that allowed the terrorist attack to occur.
The 1990 massacre of Sri Lankan Police Officers

The 1990 massacre of Sri Lankan Police Officers stands as a tragic and horrifying episode in the country's history. On June 11, 1990, members of the Liberation Tigers of Tamil Eelam (LTTE), a militant organization, perpetrated a mass murder of unarmed Sri Lankan Police officers in the Eastern Province of Sri Lanka. The attack resulted in the deaths of over 600 police officers, with some estimates indicating a toll as high as 774. The horrific events began with the LTTE surrounding the Batticaloa police station, abducting three policemen, and subsequently occupying the station with approximately 250 armed cadres. Sinhalese police officers and their families were sent to the airport, while Tamil police officers and their families were taken to St. Mary's Church. Amidst these actions, LTTE also seized a substantial amount of valuables and weaponry from the police station. The LTTE ordered the evacuation of all police stations in the Eastern Province by 2:30 p.m. or face severe consequences. Following the inspector general of Police Ernest Perera's instructions and at the request of President Ranasinghe Premadasa, police officers surrendered, believing they would be granted safe conduct and eventual release. However, the Sinhalese officers were sent to Army or Air Force camps, and Tamil officers were accommodated at schools. Tragically, the LTTE abducted 899 officers, with only around 125 managing to escape. The prisoners were then taken to the Vinayagapuram and Trincomalee jungles, where they were lined up, had their hands tied behind their backs, and were mercilessly shot to death. The resulting death toll from this brutal massacre ranged from 600 to 774 police officers, marking it as a horrifying chapter in Sri Lanka's history.
The Tokyo Subway Sarin Attack

The Tokyo subway sarin attack, which occurred on March 20, 1995, was a shocking act of domestic terrorism that forever scarred Japan's capital. Members of the Aum Shinrikyo cult, led by Shoko Asahara, released the deadly nerve agent sarin in five different Tokyo subway trains during the morning rush hour. The coordinated attack left 13 people dead, injured thousands, and caused widespread panic and chaos in the city. Aum Shinrikyo, a doomsday cult with apocalyptic beliefs, carried out the attack as an attempt to bring about social and political upheaval in Japan
The Oklahoma City Bombing

The Oklahoma City bombing was a devastating act of domestic terrorism that took place on April 19, 1995, in Oklahoma City, United States. Timothy McVeigh, a disgruntled former U.S. Army soldier, detonated a massive homemade bomb inside a rental truck parked outside the Alfred P. Murrah Federal Building. The explosion resulted in the deaths of 168 people, including 19 children, and injured over 500 others. The attack was one of the deadliest acts of terrorism on U.S. soil and left a profound impact on the nation. McVeigh, motivated by antigovernment and extremist beliefs, carried out the bombing as a response to perceived government overreach, specifically targeting a federal building. The Oklahoma City bombing serves as a stark reminder of the dangers of domestic extremism and the importance of vigilance in safeguarding against acts of terrorism, even within one's own country.
The 1998 United States Embassy Bombings

The 1998 United States embassy bombings were heinous acts of terrorism that occurred on August 7, 1998. These devastating attacks unfolded simultaneously in two East African cities, resulting in the loss of more than 220 lives. One of the explosions targeted the United States Embassy in Dar es Salaam, Tanzania, while the other struck the United States Embassy in Nairobi, Kenya. Fazul Abdullah Mohammed and Abdullah Ahmed Abdullah were identified as the masterminds behind these coordinated bombings. These tragic events underscored the global reach and threat posed by international terrorist organizations, leading to increased vigilance and counterterrorism efforts by nations worldwide in response to such acts of violence.
The Russian Apartment Bombings

The Russian apartment bombings in September 1999 were a series of horrific explosions that shook Russia, targeting apartment blocks in Buynaksk, Moscow, and Volgodonsk. These bombings resulted in the deaths of over 300 people and left more than 1,000 injured, instilling widespread fear throughout the country. The bombings, combined with the Invasion of Dagestan, served as a catalyst for the Second Chechen War. The crisis was instrumental in boosting the popularity of Vladimir Putin, who was the prime minister at the time, and ultimately helped him ascend to the presidency within a few months. While Chechen militants were initially blamed for the bombings, they denied responsibility, as did Chechen president Aslan Maskhadov. A suspicious device resembling those used in the bombings was discovered and defused in Ryazan on September 22, prompting Putin to order the air bombing of Grozny, marking the beginning of the Second Chechen War. However, it was later claimed by the authorities that the Ryazan incident was an anti-terror drill, further adding to the intrigue and controversy surrounding the bombings. The official investigations, which concluded in the early 2000s, led to convictions, but attempts at independent investigations have faced significant obstacles and obstructions. The Russian apartment bombings remain a dark and contentious chapter in Russia's recent history.
The 2002 Bali Bombings

The 2002 Bali bombings, which took place on October 12, 2002, in the popular tourist district of Kuta on the Indonesian island of Bali, were a devastating and tragic act of terrorism. Coordinated bombings targeted popular nightclubs and restaurants, resulting in the loss of 202 lives, including 88 Australians, 38 Indonesians, 23 Britons, and people from over 20 other nationalities. An additional 209 individuals suffered injuries in the attacks. The bombings shocked the world and had a profound impact on Indonesia and its tourism industry. The investigation that followed led to the identification and capture of those responsible, primarily members of the militant group Jemaah Islamiyah.
The Beslan School Siege

The Beslan school siege, which began on September 1, 2004, was a horrifying and protracted terrorist attack that unfolded over three agonizing days in Beslan, North Ossetia, Russia. During the siege, more than 1,100 people, including 777 children, were held hostage by a group of militants. The siege ultimately ended in a tragic and devastating loss of life, with 333 people losing their lives, including 186 children, making it one of the deadliest school shootings in history. The attackers' actions shocked the world and left a lasting scar on the collective memory of Russia and the international community. The Beslan school siege stands as a somber reminder of the capacity for extreme violence and the importance of vigilance in safeguarding innocent lives.
The Qahtaniyah Bombings

The Qahtaniyah bombings on August 14, 2007, were a series of coordinated suicide car bomb attacks that occurred in the Yazidi towns of Til Ezer (al-Qahtaniyah) and Siba Sheikh Khidir (al-Jazirah) in northern Iraq. These devastating attacks resulted in the tragic loss of 796 lives and left at least 1,500 others wounded, making it the deadliest car bomb attack during the Iraq War. This event ranks as the fourth deadliest act of terrorism in world history, following the September 11 attacks in the United States, the 2023 Hamas attack on Israel, and the Camp Speicher massacre, also in Iraq. Despite the significant loss of life and devastation, no group claimed responsibility for these attacks.
The 2008 Christmas Massacres

The 2008 Christmas massacres, which unfolded from December 24 to 27, 2008, were a series of brutal attacks carried out by the Lord's Resistance Army (LRA), a notorious Ugandan rebel group, in Haut-Uele District, Democratic Republic of the Congo. During this dark period, the LRA targeted several villages, unleashing widespread violence and terror. The attacks resulted in the tragic loss of numerous innocent lives, with reports of widespread killings, abductions, and other atrocities. The LRA, known for its brutal tactics and use of child soldiers, inflicted immense suffering on the local population. These Christmas massacres served as a stark reminder of the ongoing instability and violence that have plagued the region for years, highlighting the urgent need for international efforts to address the humanitarian crisis and bring those responsible for such heinous acts to justice.
The November 2015 Paris Attacks

The November 2015 Paris attacks, which unfolded on Friday, November 13, 2015, in Paris, France, and the suburb of Saint-Denis, marked a horrifying and coordinated series of militant attacks carried out by ISIL extremists. The evening of terror began with three suicide bombers targeting the Stade de France in Saint-Denis, where an international football match was taking place. Failing to gain entry to the stadium, they detonated their explosives outside.
Simultaneously, another group of attackers opened fire on crowded cafés and restaurants in Paris, with one attacker also detonating an explosive device, killing himself. A third group carried out a mass shooting and took hostages at the Bataclan theatre during an Eagles of Death Metal concert, resulting in a stand-off with police. The attackers killed 130 people, including 90 at the Bataclan theatre, and injured 416 others, nearly 100 of them critically. Seven attackers were also killed.
These attacks were the deadliest in metropolitan France since the Paris massacre of 1961 and the deadliest in the European Union since the Madrid train bombings of 2004. ISIL claimed responsibility, citing it as retaliation for French airstrikes on their targets in Syria and Iraq, and the attacks came one day after similar attacks in Beirut, Lebanon. France had been on high alert following the January 2015 attacks on Charlie Hebdo offices and a Jewish supermarket in Paris.
The November 2016 Hillah Suicide Truck Bombing

The November 2016 Hillah Suicide Truck Bombing was a horrifying act of terrorism that unfolded in Iraq on November 24, 2016. A suicide bomber detonated a truck packed with explosives at a petrol station in Hillah, located approximately 100 kilometers (62 miles) south of Baghdad. This devastating attack claimed the lives of at least 125 people and left many others with severe injuries. The victims primarily consisted of Shia pilgrims who were on their way back to Iran following their participation in the 2016 Arba'een Pilgrimage. Tragically, the casualties included not only Iranians but also individuals from Basra and Nasiriyah. The Islamic State of Iraq and the Levant (ISIL) claimed responsibility for this brutal act, highlighting the ongoing threat of terrorism in the region and the profound human toll it inflicts on innocent civilians.
The 2016 Nice Truck Attack

The 2016 Nice truck attack was a horrific terrorist act that occurred on the evening of July 14, 2016, during Bastille Day celebrations in Nice, France. A large cargo truck was deliberately driven into a crowd of people who had gathered along the Promenade des Anglais to watch fireworks, resulting in a devastating and deadly rampage. The attacker, Mohamed Lahouaiej-Bouhlel, drove the truck for over a mile through the densely populated area, mowing down pedestrians and causing chaos and panic. In the wake of this brutal attack, 86 people lost their lives, and hundreds more were injured, some critically. The attack was condemned worldwide, and it underscored the persistent threat of terrorism in the modern era.
The 2016 Brussels Bombings

The 2016 Brussels bombings were a tragic and coordinated terrorist attack that took place on March 22, 2016, in and around Brussels, Belgium, and were carried out by the Islamic State (IS). The attacks unfolded with two suicide bombers detonating their explosives at Brussels Airport in Zaventem, just outside the city, while another suicide bomber targeted a train leaving the Maelbeek/Maalbeek metro station in the European Quarter of Brussels. These heinous acts resulted in the loss of 32 lives and left more than 300 people injured. The attackers themselves also perished in the attacks. Notably, one of the airport attackers fled the scene without detonating his bomb, which was later discovered during a search of the airport. Another metro attacker fled, taking his bomb with him. The Islamic State claimed responsibility for these devastating attacks, which were connected to a terrorist cell involved in the November 2015 Paris attacks. Belgium declared three days of national mourning following the bombings, which were the deadliest attacks in the country since World War II. In December 2022, ten men accused of involvement in the attacks stood trial in Brussels, resulting in convictions for several individuals on charges related to terrorism, murder, and attempted murder.
The 2011 Norway Attacks

The 2011 Norway attacks, known as 22 July or 22/7 in Norway, were two horrifying domestic terrorist acts carried out by far-right extremist Anders Behring Breivik. These attacks targeted the government, civilian population, and a Workers' Youth League (AUF) summer camp, resulting in a tragic toll of 77 lives lost. The first attack was a car bomb explosion in Oslo, within the executive government quarter of Norway called Regjeringskvartalet, occurring at 15:25:22 (CEST).
The bomb, concealed inside a van parked near the office of then-Prime Minister Jens Stoltenberg, claimed eight lives and injured over 200 people, with a dozen suffering severe injuries. The second attack unfolded less than two hours later on the island of Utøya in Tyrifjorden, Viken, where a summer camp organized by the AUF, the youth wing of the ruling Norwegian Labour Party, was taking place. Breivik, disguised in a homemade police uniform, opened fire on the camp's participants, killing 69 individuals and injuring 32. This attack on Utøya remains the deadliest mass shooting by a lone individual in modern history.
The 2011 Norway attacks stand as the deadliest in Norway since World War II, leaving a lasting impact on the nation, as one in four Norwegians reported knowing someone affected by the tragedy.
