Evacuation flights from Afghanistan resumed with new urgency on Friday, a day after two suicide bombings targeted the thousands of people desperately fleeing a Taliban takeover and killed more than 100. The U.S. warned more attacks could come ahead of the looming deadline for foreign troops to leave, ending America’s longest war. As the call to prayer echoed through Kabul along with the roar of departing planes, the anxious crowd outside the city’s airport was as large as ever.

Dozens of Taliban members carrying heavy weapons patrolled one area about 500 meters (1,600 feet) from the facility to prevent anyone from venturing beyond. Thursday’s bombings near the airport killed at least 95 Afghans and 13 U.S. troops, Afghan and U.S. officials said, in the deadliest day for American forces in Afghanistan since August 2011.
