Osama bin Mohammed bin Awad bin Laden was a Saudi Arabian-born Islamist dissident and militant leader who was the founder and first general emir of al-Qaeda from 1988 until his death in 2011. Ideologically a pan-Islamist, he participated in the Afghan jihad against the Soviet Union and supported the activities of the Bosnian mujahideen during the Yugoslav Wars. Bin Laden is considered to have been the mastermind behind the September 11 attacks in the United States.
The aircraft hijackers in the September 11 attacks were 19 men affiliated with jihadist organization al-Qaeda. They hailed from four countries; 15 of them were citizens of Saudi Arabia, two were from the United Arab Emirates, one was from Egypt, and one from Lebanon. To carry out the attacks, the hijackers were organized into four teams each led by a pilot-trained hijacker who would commandeer the flight with three or four "muscle hijackers" who were trained to help subdue the pilots, passengers, and crew. Each team was assigned to a different flight and given a unique target to crash their respective planes into. Mohamed Atta was the assigned ringleader over all 4 groups.
The following lists events that happened during 2001 in Afghanistan.
Said Bahaji, was a citizen of Germany, electrical engineer, and an alleged member of the Hamburg cell that provided money and material support to the perpetrators of the September 11 attacks.
Wadih Elias el-Hage is a Lebanese and naturalized American citizen, who is serving life imprisonment in the United States based on conspiracy charges relating to the 1998 United States embassy bombings.
Mohamed Salah al-Din al-Halim Zaidan, commonly known by his nom de guerreSaif al-Adel, is a former Egyptian Army officer and explosives expert who is widely understood to be the de facto leader of al-Qaeda. Al-Adel fought the Soviets as an Afghan Arab before becoming a founding member of the al-Qaeda organization. He is a member of Al-Qaeda's Majlis al-Shura and has headed the organization's military committee since the death of Muhammad Atef in 2001. He is currently known to live in Iran along with several other senior members of the group.
Operation Infinite Reach was the codename for American cruise missile strikes on al-Qaeda bases that were launched concurrently across two continents on 20 August 1998. Launched by the U.S. Navy, the strikes hit the al-Shifa pharmaceutical factory in Khartoum, Sudan, and a camp in Khost Province, Afghanistan, in retaliation for al-Qaeda's August 7 bombings of American embassies in Kenya and Tanzania, which killed 224 people and injured over 4,000 others. Operation Infinite Reach was the first time the United States acknowledged a preemptive strike against a violent non-state actor.
Walid Muhammad Salih bin Mubarak bin Attash is a Yemeni prisoner held at the United States' Guantanamo Bay detention camp under terrorism-related charges and is suspected of playing a key role in the early stages of the 9/11 attacks. The Office of the Director of National Intelligence has described him as a "scion of a terrorist family". American prosecutors at the Guantanamo military commissions allege that he helped in the preparation of the 1998 East Africa Embassy bombings and the USS Cole bombing and acted as a bodyguard to Osama bin Laden, gaining himself the reputation of an "errand boy". He is formally charged with selecting and helping to train several of the hijackers of the September 11 attacks. On 31 July 2024, Attash agreed to plead guilty to avoid the death penalty. His plea deal was revoked by Secretary of Defense Lloyd Austin two days later.
On September 11, 2001, 19 al-Qaeda terrorists took control of four commercial aircraft and used them as suicide weapons in a series of four coordinated acts of terrorism to strike the World Trade Center in New York City, The Pentagon in Arlington County, Virginia, and an additional target in Washington, D.C. Two aircraft hit the World Trade Center while the third hit the Pentagon. A fourth plane did not arrive at its target, but crashed into a field in Pennsylvania after a passenger revolt. The intended target is believed to have been the United States Capitol. As a result, 2,977 victims were killed, making it the deadliest foreign attack on U.S. soil, exceeding Japan's surprise attack on Pearl Harbor in Honolulu, Hawaii, on December 7, 1941, which killed 2,335 members of the United States Armed Forces and 68 civilians. The effort was carefully planned by al-Qaeda, which sent 19 terrorists to take over Boeing 757 and Boeing 767 aircraft, operated by American Airlines and United Airlines.
The Northern Alliance, officially known as the United Islamic National Front for the Salvation of Afghanistan, was a military alliance of groups that operated between early 1992 and 2001 following the dissolution of the Soviet Union. At that time, many non-Pashtun Northerners originally with the Republic of Afghanistan led by Mohammad Najibullah became disaffected with Pashtun Khalqist Afghan Army officers holding control over non-Pashtun militias in the North. Defectors such as Rashid Dostum and Abdul Momim allied with Ahmad Shah Massoud and Ali Mazari forming the Northern Alliance. The alliance's capture of Mazar-i-Sharif and more importantly the supplies kept there crippled the Afghan military and began the end of Najibullah's government. Following the collapse of Najibullah's government the Alliance would fall with a Second Civil War breaking out however following the Islamic Emirate of Afghanistan's (Taliban) takeover of Kabul, The United Front was reassembled.
The September 11 attacks, commonly known as 9/11, were four coordinated Islamist terrorist suicide attacks carried out by al-Qaeda against the United States in 2001. On that morning, 19 terrorists hijacked four commercial airliners scheduled to travel from the East Coast to California. The hijackers crashed the first two planes into the Twin Towers of the World Trade Center in New York City and aimed the next two flights toward targets in or near Washington, D.C., in an attack on the nation's capital. The third team succeeded in striking the Pentagon, the headquarters of the U.S. Department of Defense in Arlington County, Virginia, while the fourth plane crashed in rural Pennsylvania during a passenger revolt. The September 11 attacks killed 2,977 people, making it the deadliest terrorist attack in history. In response to the attacks, the United States waged the multi-decade global war on terror to eliminate hostile groups deemed terrorist organizations, as well as the foreign governments purported to support them, in Afghanistan, Iraq, Syria, and several other countries.
Osama bin Laden, the founder and former leader of al-Qaeda, went into hiding following the start of the War in Afghanistan in order to avoid capture by the United States for role in the September 11 attacks, and having been on the FBI Ten Most Wanted Fugitives list since 1999. After evading capture at the Battle of Tora Bora in December 2001, his whereabouts became unclear, and various rumours about his health, continued role in al-Qaeda, and location were circulated. Bin Laden also released several video and audio recordings during this time.
Hamza bin Osama bin Mohammed bin Awad bin Laden, better known as Hamza bin Laden, was a Saudi Arabian-born member of al-Qaeda. He was a son of al-Qaeda leader Osama bin Laden, and, following his father's death in 2011, he was described as an emerging leader of the al-Qaeda organization.
After the Central Intelligence Agency lost its role as the coordinator of the entire United States Intelligence Community (IC), special coordinating structures were created by each president to fit his administrative style and the perceived level of threat from terrorists during his term.
Regional and tribal Afghan leaders rose up and formed an alliance known as the Eastern Shura to oust the Taliban in Khowst Province and Nangarhar Province, during the War in Afghanistan. Mary Anne Weaver, writing in The New York Times on the fourth anniversary of al Qaeda's attacks on September 11, 2001, described the formation of the Eastern Shura as the result of surrender negotiations on November 13, 2001, between Mohammad Yunus Khalis and Osama bin Laden.
Pakistan and state-sponsored terrorism refers to the involvement of Pakistan in terrorism through the backing of various designated terrorist organizations. Pakistan has been frequently accused by various countries, including its neighbours Afghanistan, Iran, and India, as well as by the United States, the United Kingdom, Germany, and France, of involvement in a variety of terrorist activities in both its local region of South Asia and beyond. Pakistan's northwestern tribal regions along the Afghanistan–Pakistan border have been described as an effective safe haven for terrorists by Western media and the United States Secretary of Defense, while India has accused Pakistan of perpetuating the insurgency in Jammu and Kashmir by providing financial support and armaments to militant groups, as well as by sending state-trained terrorists across the Line of Control and de facto India–Pakistan border to launch attacks in Indian-administered Kashmir and India proper, respectively. According to an analysis published by the Saban Center for Middle East Policy at the Brookings Institution in 2008, Pakistan was reportedly, with the possible exception of Iran, perhaps the world's most active sponsor of terrorist groups; aiding these groups that pose a direct threat to the United States. Pakistan's active participation has caused thousands of deaths in the region; all these years Pakistan has been supportive to several terrorist groups despite several stern warnings from the international community. Daniel Byman, a professor and senior analyst of terrorism and security at the Center For Middle East Policy, also wrote that Pakistan is probably 2008's most active sponsor of terrorism. In 2018, the former Prime Minister of Pakistan, Nawaz Sharif, suggested that the Pakistani government played a role in the 2008 Mumbai attacks that were carried out by Lashkar-e-Taiba, a Pakistan-based Islamist terrorist group. In July 2019, Pakistani Prime Minister Imran Khan, on an official visit to the United States, acknowledged the presence of some 30,000–40,000 armed terrorists operating on Pakistani soil. He further stated that previous administrations were hiding this truth, particularly from the United States, for the last 15 years during the War on Terror.
Since the early 1990s, several interviews of Osama bin Laden have appeared in the global media. Among these was an interview by Middle East specialist Robert Fisk. In the interviews, Bin Laden acknowledges having instigated bombings in Khobar, Saudi Arabia in 1996 and Riyadh, Saudi Arabia in 2003, but denies involvement with both the 1993 and 2001 attacks on the WTC towers in New York City.
At around 9:30 pm on September 11, 2001, George Tenet, director of the Central Intelligence Agency (CIA), told President George W. Bush and U.S. senior officials that the CIA's Counterterrorism Center had determined that Osama bin Laden and al-Qaeda were responsible for the September 11 attacks. Two weeks after the terrorist attacks on September 11, 2001, the Federal Bureau of Investigation connected the hijackers to al-Qaeda, a militant Salafist Islamist multi-national organization. In a number of video, audio, interview and printed statements, senior members of al-Qaeda have also asserted responsibility for organizing the September 11 attacks.
In the aftermath of the September 11 attacks on New York City and Washington, D.C., by the al-Qaeda terrorist group, a number of investigations were conducted to determine what intelligence may have existed before the attacks and whether this information was ignored by authorities.
The following is an outline of the series of events that led up the War in Afghanistan (2001–2021).
