Afghanistan evacuation efforts continue amid airport chaos, security threat

U.S. Defense Department officials say they are trying to evacuate people from Afghanistan "as quickly and safely as possible" as Afghans and Americans continue to rush to Kabul's airport in an attempt to flee the Taliban, causing chaos and confusion. 

Earlier Saturday, the U.S. Embassy in Kabul sent out an alert on its website "advising U.S. citizens to avoid traveling to the airport and to avoid airport gates at this time unless you receive individual instructions from a U.S. government representative to do so" due to ongoing security threats. A defense official told CBS News that the warning was prompted by intelligence that ISIS-K is planning an attack. With the ISIS threat making it dangerous for Americans to travel to the airport, the U.S. military may have to resort to using helicopters to pick them up at locations around the city, an expansion of operations that could upset arrangements the U.S. has worked out with the Taliban on the ground. President Joe Biden and Vice President Kamala Harris, who is traveling to Singapore but joined via video, met with the administration's national security team Saturday morning to discuss the security situation in Afghanistan and counter-terrorism operations, including ISIS-K.
