“The clearance of trucks is in process and Afghan citizens are entering Afghanistan after clearance and passing immigration processes,” Irshad Khan Mohmamd, assistant commissioner of Khyber district in Pakistan, told AFP.

Islamabad and Kabul have been in diplomatic deadlock since border guards opened fire at the Torkham crossing on September 6, halfway between the two capitals, in a dispute over an under-construction Afghan outpost.

Each blamed the other for firing the first salvo last Wednesday, souring already poor relations between Islamabad and Afghanistan’s Taliban rulers.

The crossing is the busiest for trade and people between the two nations, which share a porous 2,600-kilometre (1,600-mile) frontier that cuts through rugged mountains and valleys.

Traders on both sides complained that tonnes of perishable goods were lost because of the border closure, while Afghan travellers missed vital hospital appointments or flights out of Pakistan.
