The embassy issued a security alert on Saturday encouraging Americans to fly out on commercial flights and said it can provide repatriation loans for citizens who can't afford to buy tickets.

The alert comes months after the State Department ordered government employees at the US embassy in Kabul to leave if they can work elsewhere. It also comes as Taliban militants are attacking Afghan cities.

The Taliban is fighting to take power after the group signed a withdrawal deal with the Americans in 2020 and the Biden administration vowed a withdrawal from Afghanistan by the end of August.
