NATO helicopters attack Pakistan

Pakistan is reporting that two NATO helicopters attacked a Pakistani security checkpoint in North Waziristan.  Also, a U.S. drone attack killed 12 people in the same region.

No response so far from NATO forces on why they attacked a security checkpoint.  This is not the first time; last year U.S. helicopters did the same thing, killing two Pakistani soldiers.

These attacks come as U.S. Senator John Kerry is in Pakistan, to try an reconcile the May 1/2 Osama bin Laden operation with Pakistani officials.
