Any foreign troops left in Afghanistan after Nato’s September withdrawal deadline will be at risk as occupiers, the Taliban has told the BBC.

It comes amid reports that 1,000 mainly US troops could remain on the ground to protect diplomatic missions and Kabul’s international airport.

Nato’s 20-year military mission in Afghanistan has all but ended.

But violence in the country continues to rise, with the Taliban taking more territory.

Under a deal with the militant group, the US and its Nato allies agreed to withdraw all troops in return for a commitment by the Taliban not to allow al-Qaeda or any other extremist group to operate in the areas they control.

President Joe Biden set a deadline of 11 September – the 20-year anniversary of the 9/11 attacks on the US – for American troops to fully withdraw, but reports suggest the pullout may be complete within days.

As Afghan forces prepare to take charge of security alone, concern is growing for the future of Kabul.

Taliban spokesman Suhail Shaheen said seizing Kabul militarily was “not Taliban policy”.

President Biden has said the American pull-out is justified as US forces have made sure Afghanistan cannot become a base for foreign jihadists to plot against the West again.

Afghan President Ashraf Ghani, meanwhile, insists that the country’s security forces are fully capable of keeping insurgents at bay, but many believe the withdrawal risks casting the country back into the grip of the Taliban.

Taliban: “US forces remaining would violate Doha agreement”.
