The Pakistani Taliban has threatened to attack trucks that carry supplies to NATO troops in Afghanistan after the U.S. and Pakistani governments reached a deal to re-open the route.

“We will attack NATO supplies all over Pakistan,” a spokesman for the Taliban told Reuters. “We will not allow anyone to use Pakistani soil to transport supplies that will be used against the Afghan people.”

Reportedly, Islamabad agreed to re-open the supply routes after U.S. government officials apologized for the accidental killing of 24 Pakistani soldiers in a missile attack last November.
