let's get more on those reports that the taliban are preparing to take over kabul airport when us troops leave. our chief international correspondent lyse doucet is in kabul and sent this update. it seems in the same way the taliban fighters stole a march suddenly on kabul last week, they're doing the same tonight at the airport. for the past few hours, we've been watching on social media as senior officials among the taliban and their supporters are posting photographs with exclamations like: "the foreign occupation has ended." "the islamic emirate is entering the airport." pictures of luxury vehicles, their lights blaring, going into the airport ground. of course, we checked with the pentagon. they say, "we still control the gates, we still control the operation." the mod in london says the military flights are continuing, but it underlines again it is just a matter of time. but such is the desperation of those who got so close and now feel they may lose out,
