The nearly decade-long manhunt for bin Laden concluded on May 2, 2011, when he was killed during a U.S. military raid after being tracked down to his compound in Abbottabad, Pakistan. The war in Afghanistan continued for another eight years until the agreement was made in February 2020 for American and NATO troops to withdraw from the country, and the last members of the U.S. armed forces left the region on August 30, 2021, resulting in the return to power of the Taliban.
Not including the hijackers, the attacks killed 2,977 people, injured thousands more and gave rise to substantial long-term health consequences while also generating at least $10 billion in infrastructure and property damage. It has been described by many as the deadliest terrorist act in human history and remains the deadliest incident for both firefighters and law enforcement personnel in the history of the United States, killing 340 and 72 from each organization.
