This is interesting. I was pretty sure something like this had to be going on.

(CNN)The US military negotiated a secret arrangement with the Taliban that resulted in Taliban members escorting groups of Americans to the gates of the Kabul airport as they sought to escape Afghanistan, according to two defense officials.

One of the officials also revealed that US special operations forces set up a “secret gate” at the airport and established “call centers” to guide Americans through the evacuation process.

The officials said Americans were notified to gather at pre-set “muster points” close to the airport where the Taliban would gather the Americans, check their credentials and take them a short distance to a gate manned by American forces who were standing by to let them inside amid huge crowds of Afghans seeking to flee. https://amp.cnn.com/cnn/2021/08/31/politics/taliban-escorted-american-kabul-airport/index.html
