The United States finished its withdrawal efforts from the airport in Kabul, Afghanistan, effectively ending a 2-decade conflict that began not long after the terrorist attacks of Sept. 11, 2001. In the final week of the withdrawal, terrorists from the group ISIS-K killed 13 U.S. service members and dozens of Afghans in an attack outside the airport. U.S. forces retaliated and launched strikes in a bid to thwart other attacks. About 122,800 people have been evacuated since the end of July, including nearly 6,000 U.S. citizens and their families.
