The suicide bombers had struck hours earlier at two locations along the perimeter of Hamid Karzai International Airport, near the Abbey Gate and outside a nearby hotel.
Dozens of Afghans and 13 U.S. troops were killed, according to U.S. and Afghan officials. At least 143 other Afghans were wounded, according to The Associated Press.
U.S. General Frank McKenzie, head of U.S. Central Command, said during a Pentagon news briefing that 11 Marines and one Navy medic were killed and 15 other troops were injured. Late Thursday, Captain Bill Urban, also of U.S. Central Command, said the death toll had risen to 13 and the injured to 18.
