The United States on Monday evacuated roughly 48,000 people from Afghanistan in recent days, though thousands are still trying to escape, fearing reprisals from the Taliban militants now in power.

Many haven't been able to leave the Kabul airport because of the gunfire and crowds, despite having the right paperwork to leave.

 The Taliban has set an airlift deadline of Aug. 31 and there are concerns many who want to leave the country won’t be able to do so.
