Taliban guard airport as most NATO troops leave Afghanistan

Taliban forces sealed off Kabul's airport Saturday to most Afghans hoping for evacuation, as the U.S. and its allies were ending a chaotic airlift that will end their troops' two decades in Afghanistan.

Western leaders acknowledged their withdrawal would mean leaving behind some of their citizens and many locals who helped them over the years, and they vowed to try to continue working with the Taliban to allow local allies to leave after President Joe Biden's Tuesday's deadline to withdraw from the country.

Although most of its allies had finished their evacuation flights, the U.S. planned to keep its roundthe-clock flights going until the deadline, saying 113,500 people had been evacuated since Aug. 14, the day before the Taliban claimed Kabul. Biden warned Saturday that commanders had told him another attack was "highly likely in the next 24-36 hours," and the U.S. Embassy issued a new warning early Sunday for all Americans to avoid the airport area entirely.

Britain ended its evacuation flights Saturday, though Prime Minister Boris

Johnson promised to "shift heaven and earth" to get more of those at risk from the Taliban to Britain by other means.

Britain's ambassador to Afghanistan, Laurie Bristow, said in a video from Kabul airport and posted on Twitter that it was "time to close this phase of the operation now."

"But we haven't forgotten the people who still need to leave," he said. "We'll continue to do everything we can to help them.

Nor have we forgotten the brave, decent people of Afghanistan. They deserve to live in peace and security."
