Pakistan Says U.S. drones in its Air Space will be Shot Down

This is what the billions and billions of foreign aid have bought us.

ISLAMABAD -- Pakistan will shoot down any U.S. drone that intrudes its air space per new directives, a senior Pakistani official told NBC News on Saturday.

According to the new Pakistani defense policy, "Any object entering into our air space, including U.S. drones, will be treated as hostile and be shot down," a senior Pakistani military official told NBC News.

The policy change comes just weeks after a deadly NATO attack on Pakistani military checkpoints accidentally killed 24 Pakistani soldiers, prompting Pakistani officials to order all U.S. personnel out of a remote airfield in Pakistan.

Pakistan told the U.S. to vacate Shamsi Air Base by December 11.
