The Taliban have agreed to allow “safe passage” from Afghanistan for civilians hoping to join a U.S.-directed airlift from the capital, President Joe Biden's national security adviser said Tuesday, although a timetable for completing the evacuation of Americans, Afghan allies and possibly other civilians has yet to be worked out with the country's new rulers. Jake Sullivan acknowledged reports that some civilians were encountering resistance - “being turned away or pushed back or even beaten” - as they tried to reach the Kabul international airport. He said “very large numbers” were reaching the airport and the problem of others was being taken up with the Taliban, whose stunningly swift takeover of the country on Sunday plunged the U.S. evacuation effort into chaos, confusion and violence. Pentagon spokesman John Kirby disclosed that U.S. commanders are speaking with Taliban commanders multiple times a day about avoiding conflict at the airport. This suggested that the new rulers of Afghanistan, who swept to power after 20 years of war against the U.S.-supported Kabul government, plan not to disrupt the evacuation. Kirby would not discuss details of the Taliban arrangement, and Sullivan said the question of how much time the Taliban will give the evacuation is still being negotiated. Biden has said he wants the evacuation completed by Aug. 31. Sullivan declined to say whether that deadline would hold. Sullivan said U.S. officials are engaged in an “hour by hour” process of holding the Taliban to their commitment to allow safe passage for civilians wishing to leave the country. Asked whether the Biden administration recognizes the Taliban as the legitimate rulers of Afghanistan, Sullivan said it was too soon to say and that the Taliban's record of adhering to international human rights standards “has not been good.” Overnight at the airport, nine Air Force C-17 transport planes arrived with equipment and about 1,000 troops, and seven C-17s took off with 700-800 civilian evacuees, including 165 Americans, Army Maj. Gen. William Taylor told a Pentagon news conference. The total included Afghans who have applied for Special Immigrant Visas and third-country nationals, he said. On Monday the airlift had been temporarily suspended when Afghans desperate to escape the country breeched security and rushed onto the tarmac. Seven people died in several incidents. On Monday, a defiant Biden rejected blame for chaotic scenes of Afghans clinging to U.S. military planes in Kabul in a desperate bid to flee their home country after the Taliban's easy victory over an Afghan military that America and NATO allies had spent two decades trying to build. His grim comments were his first in person to the world since the biggest foreign policy crisis of his still-young presidency. Emboldened by the U.S. withdrawal, Taliban fighters swept across the country last week and captured the capital, Kabul, on Sunday, sending U.S.-backed Afghan President Ashraf Ghani fleeing the country.
