sflrpt anderson, the key point the pentagon was making is it's now time to essentially make sure that u.s. embassy staff there can get out as part of the a partial drawdown of the embassy staff and serve another purpose in securing hamid karzai international airport, which is effectively the international gateway in and out of the country, especially now with the surge of the taliban. they will also be there to assist in the secure withdrawal and removal of afghan interpreters who've helped the u.s. as well as their families to get out of the country, a process that is rapidly accelerating. very much a sudden urgency on the part of the biden administration with the advance of the taliban and the momentum they have. it doesn't show any signs of slowing down. >> so the u.s. embassy in kabul's urging american citizens to leave the country immediately. we have teams on the ground there. what are americans' options for getting out? there are still some commercial flights. and turkey -- turkish troops control the airport now. >> turkish troops are in charge of security at the airport. there are some u.s. troops that are there as well. you're absolutely right, anderson.
