Taliban checkpoints and paperwork prevent evacuees from getting to airport as militants search for those who worked with previous regime
Tens of thousands of Americans and Afghans who collaborated with US forces remain stranded in Kabul, as the US government grappled with an overwhelming backlog of visas and Taliban checkpoints which were preventing people safely reaching the airport.
With the 31 August deadline looming, tens of thousands of people eligible for evacuation were yet to be airlifted out, many who were among the crowds gathered around Kabul airport brandishing their papers or proof they had worked on US bases.
