PAKISTAN closed the Torkham border crossing in the Khyber tribal agency. The road through the Khyber Pass is NATO's primary supply line into Afghanistan, a private TV channel reported on Saturday. The government claimed that poor security on the strategic road into Afghanistan forced the closure. The road has been shut down exclusively for NATO traffic. "All Afghanistan-bound supplies for the International Security Assistance Force (ISAF) have been stopped as the [Torkham] highway is vulnerable," the Khyber Agency's political agent Tariq Hayat told reporters. Last week's incident of looting of wheat and military supplies meant for Afghanistan and Nato in Jamrud should also be seen in the same light. World Food Program has complained that 900 tons of humanitarian food and oil supplies for the poor in Afghanistan and Pakistan worth $1 million have been looted.
