ISLAMABAD Pakistan on Saturday restored NATO supply route through Torkham with immediate effect. After assessing the security situation in all its aspects, the Government has decided to reopen the NATO/ISAF supply from the Pakistan-Afghanistan border at Torkham with immediate effect. Our relevant authorities are now in the process of coordinating with authorities on the other side of the border to ensure smooth resumption of the supply traffic, Foreign Office stated on Saturday evening. The main northwestern crossing at Torkham was closed 10 days ago after a cross-border air strike by NATO forces which left three FC men dead. Following the attack on soldiers, Pakistan halted supplies to NATO which was restored after the US and NATO took responsibility of the attack and apologised from the Government of Pakistan in this regard. According to official sources from Peshawar, trucks started crossing the border on Saturday evening. Agencies add: Torkham lies on the main NATO supply route to Afghanistan, where US and NATO forces are fighting a nine-year Taliban insurgency, and is thus vital to the Afghan war effort. Richard Snelsire, the US embassy spokesman, said Washington welcomed the reopening of the border crossing, and called it a positive development. The US ambassador to Pakistan Anne Patterson Wednesday apologised on behalf of the American people for the terrible accident. Patterson said Thursday in a statement: A joint investigation of the incident had established that the US helicopters had mistaken the Pakistani Frontier Scouts for insurgents they had been pursuing. Amid the differences over the NATO helicopter attack, more than 100 NATO oil tankers and supply trucks have been destroyed in militant attacks in just over a week as the rebels step up their efforts to disrupt supplies. A second border crossing at Chaman in Balochistan province remains open.
