An Afghan government defence official said Sunday that a deal over Bagram air base was "not possible", after US President Donald Trump said he wanted the former US base back.

Axar.az informs, citing France 24, Bagram, the largest air base in Afghanistan located north of the capital Kabul, was the centre of US operations in their 20 year-war against the Taliban.

Trump threatened unspecified punishment against Afghanistan if it was not returned -- four years after it was abandoned by US troops.

On Sunday, Fasihuddin Fitrat, chief of staff of Afghanistan's ministry of defence, said "some people" want to take back the base through a "political deal".

"Recently, some people have said that they have entered negotiations with Afghanistan for taking back Bagram air base," he said in comments broadcast by local media.

"A deal over even an inch of Afghanistan's soil is not possible. We don't need it."

Later in an official statement, the Afghan government said warned that "Afghanistan's independence and territorial integrity are of the utmost importance".
