Pakistani police say a car bombing in the country's southwest hit trucks taking supplies to Western troops in Afghanistan. Four people died in the blast, The Associated Press reported. The bomb detonated Tuesday outside a roadside restaurant in Baluchistan province. The restaurant is popular with truckers who ferry supplies to U.S. and NATO troops in Afghanistan. Police officer Khuda Bukhsh said a wounded truck driver told him his vehicle carried the troop supplies. At least three trucks were parked when the bomb exploded.
