Pakistani intelligence officials say a U.S. missile strike has killed three people near the Afghan border.

Four missiles struck a vehicle Friday in the Doga Madakhel village of North Waziristan tribal region. North Waziristan is home to many militant groups dedicated to attacking Western troops in Afghanistan.

The two officials spoke on condition of anonymity because they were not authorized to speak to media. They did not know the exact identities of the dead.

The strike comes amid tensions between the U.S. and Pakistan over the May 2 American raid that killed al-Qaida chief Osama bin Laden on Pakistani soil. The U.S. relies heavily on the covert, CIA-run missile program to kill Taliban and al-Qaida militants in Pakistan's tribal areas.
