Biden reflects on longest US war in Afghanistan

US President Joe Biden has addressed Americans on the withdrawal of troops from Afghanistan. He told them that, after 20 years, the US no longer had a clear purpose for being there.

The Taliban took over as US forces were preparing to pull out. They have promised to allow the safe passage of people and humanitarian aid.

US service members protected the airport in Kabul as more than 100,000 were airlifted out of the country. Biden said US officials would work with their partners to ensure any Americans, Afghan allies, and foreign nationals still on the ground can leave.

US and coalition forces were stationed in Afghanistan after the September 11 attacks in 2001. More than 48,000 civilians and more than 2,400 American soldiers were reported killed during the war.
