ISLAMABAD: Pakistan has closed a key crossing on its northwestern border with Afghanistan over the “construction of trenches” near the frontier, a Pakistani police official said on Sunday, which has led to the suspension of cross-border movement.

The Torkham border crossing was closed late on Friday night, when Afghan Taliban authorities initiated “construction of trenches and other development work” along the border, according to Naheed Khan, a senior police official in Pakistan’s Khyber district that borders Afghanistan.

The closure of border crossing by Pakistani authorities has resulted in suspension of movement of pedestrians and trade between the two neighboring countries, but there were no reports of skirmishes between the two sides.

“It [Torkham crossing] is closed both for pedestrians and heavy vehicles since 12 at night on Feb. 21. No firing is reported from either side,” Khan told Arab News.

“Some families of Bacha Mina, a dusty village near the border on Pakistani side, have left the area for safer places to dodge any eventuality. Also some loaded trucks have returned to Jamrud Bazaar.”

There was no immediate comment from the Afghan side on the closure of the key border crossing.

The development comes at a time of strained ties between Pakistan and Afghanistan over a surge in militants attacks in Pakistan’s western provinces that border Afghanistan.

Islamabad has frequently accused Afghanistan of sheltering and supporting militant groups that launch cross-border attacks. Afghan officials deny involvement and insist that Pakistan’s security issues are an internal matter of Islamabad.

In the past, border clashes between Pakistani and Afghan forces have led to the closure of key crossings like Torkham and Chaman, severely disrupting trade and halting the movement of people between the two countries.

In August, the Torkham border was shut down for three days after the Afghan Taliban announced they were investigating reports of Pakistani fighter jets allegedly violating Afghan airspace in Nangarhar and Kunar provinces.

Tensions escalated again between the two countries in December, following reports of Pakistani airstrikes targeting alleged militant camps in Afghanistan. Afghan officials reported the strikes resulted in civilian casualties.
