Pakistani and Afghan forces traded fire overnight at a key northwestern border crossing that has been closed for more than a week over a dispute between the two neighbors, officials said Monday. No casualties were reported on either side of the Torkham crossing, which has been shut for 11 days due to Pakistan disputing Afghanistan’s construction of a new border post there. Both countries have in the past closed Torkham and the southwestern Chaman border crossing, most often over deadly shootings and cross-fire. The crossings are vital for trade and travel between Pakistan and landlocked Afghanistan. A Pakistani official, who spoke on condition of anonymity because he was not authorized to talk to the media, said that Taliban security forces opened fire unprovoked in the early hours of Monday, targeting Pakistan´s border post with automatic weapons. Pakistani personnel returned fire, the official said. There was no immediate comment on the exchange from the Taliban government in Kabul. Thousands of trucks and vehicles are stranded on both sides of the Torkham crossing, leaving people stuck in harsh winter conditions. Separately, the country’s security forces have identified another Afghan militant killed during a recent operation against cross-border infiltration, as tensions between the two countries rise over militant incursions, security sources said on Monday. The militant, Mujib ur Rehman alias Mansoor, was among 14 insurgents killed in an intelligence-based operation in Ghulam Khan Kelay near the Afghan border on February 28, the sources said. He was a commander of the third battalion at Afghanistan’s Hazrat Muaz bin Jabal National Military Academy and a resident of Wardak province.
