Western countries are warning their nationals in Afghanistan to immediately leave the surrounding of Kabul airport, as thousands scrambling there to catch evacuation flights. The US state department has called on Americans to avoid the airport, citing unspecified security threats. Australia’s department of foreign affairs also urged its nationals not to travel to Kabul airport, asking those already in the area to move to a safe location until further notice. The UK issued similar warning, calling on Britons to leave Afghanistan safely by other means if they can. Desperate crowds have gathered in and around the airport as the August 31st deadline for forces and nationals of US and its allies to leave Afghanistan looms.
