The president ordered flags to half-staff following two deadly explosions near the airport in Kabul. 13 American service members were among the 60 fatalities. One blast struck a busy entrance to the airfield, where U.S. troops have been processing Americans and Afghans for evacuation ahead of the August 31 withdrawal deadline. ISIS-K, an offshoot of the Islamic State, has claimed responsibility for the attack. Yamiche Alcindor, Jonathan Lemire, James LaPorta, Clint Watts, Donna Edwards and Mark McKinnon all join.
