Exclusive: Whitehall and security sources worry they will not be able to continue emergency evacuations
Britain fears US forces may pull out of Kabul international airport within days, putting it at risk of closure and raising concerns over the emergency airlift of thousands of people from Afghanistan.
Whitehall and security sources said they could not guarantee how long the US would keep its contingent of 6,000 troops on the ground and cautioned that the UK could not continue the rescue without their presence. They also indicated Britain was not engaging with the Taliban directly over security or other issues after the militant group seized the Afghan capital.
