With the destruction of a bridge on the Indus Highway in the North-West Frontier Province (NWFP) region of Darra Adamkhel last weekend, the Taliban have taken another step towards choking the supplies that flood through Pakistan to the North Atlantic Treaty Organization (NATO) mission in Afghanistan.At the same time, the Taliban believe an agreement Russia concluded with NATO at its summit last week will not alleviate the situation. Moscow agreed to the transit of food and non-military cargo and "some types of non-lethal military equipment" across Russia to Afghanistan. NATO is acutely aware that the 70% of its supplies that enter Afghanistan through Pakistan are in jeopardy with the Taliban's new focus on cutting transit routes.
