All gates at Hamid Karzai International Airport were closed Saturday because of a backup at Al Udeid Air Base in Qatar, according to a Defense department official who was not authorized to speak publicly. Most U.S. military evacuation planes fly from Kabul to Qatar and the inability to handle more evacuees there is causing a ripple effect. The warning about the chaotic conditions at the airport, where thousands of people are waiting to leave, came a day after President Joe Biden said he wasn’t aware of any problems getting from downtown Kabul to the airport. “We have no indication that they haven't been able to get – in Kabul – through the airport,” Biden said Friday. President Joe Biden said Friday the administration still hopes to complete the military withdrawal by the deadline, but would continue until all Americans are out. He also committed to evacuating Afghans who helped U.S. forces. #afghanistan #kabulairport
