WASHINGTON (AP) — President Joe Biden’s national security adviser Jake Sullivan says the Taliban have agreed to allow safe passage for civilians trying to leave Afghanistan. Sullivan says a timetable for completing the evacuation of Americans, Afghan allies and others has yet to be worked out with the country’s new rulers. Pentagon officials say that after interruptions Monday, the airlift is back on track and being accelerated amid regular communication with Taliban leaders. Additional U.S. troops have arrived and more are on the way. The White House says 13 flights Tuesday airlifted 1,100 U.S. citizens, permanent residents and their families from the Kabul airport.
