With Afghanistan under the Taliban's control, countries are evacuating their citizens and issuing guidance.
Meanwhile, commercial flights out of Kabul's Hamid Karzai International Airport have been canceled, and footage filmed there showed scenes of chaos and desperation as people scrambled to get onto planes.
The US military have established a perimeter at the airport, guarding at least a portion of the sprawling complex. Several videos shared on social media shows razor wire has been laid to hold back to hundreds of people desperate to leave. American troops can be seen standing guard behind the razor wire.
It’s unclear how much of the airport the US military is controlling.
The civilian side of the airport is closed, according to a notice to airmen.
At least three airlines — United, Emirates and FlyDubai — are either suspending flights or rerouting them to avoid Afghanistan's airspace.
