Al-Qaeda began in the 1980s during the Soviet invasion of Afghanistan. It was led by Osama bin Laden and aimed to attack US interests after bin Laden was displeased by the US military presence in Saudi Arabia in the 1990s. Major al-Qaeda attacks against the US included the 1993 WTC bombing, 1998 US embassy bombings in Africa, 2000 USS Cole bombing, and the September 11, 2001 attacks which killed nearly 3,000 people and led the US to launch the War on Terror.
