Speaking at the White House, Biden said 11,000 people had been airlifted from Kabul in a 36-hour period this weekend, but he did not provide details. The number appeared to include flights by charter and non-U.S. military aircraft as well as the U.S. Air Force C-17 and C-130 transport planes that have been flying daily from the capital. Tens of thousands of people remain to join the airlift, which has been slowed by security issues and U.S. bureaucracy hurdles.
