Pakistani intelligence officials say a suspected U.S. missile strike has killed five people in the country's northwest near the Afghan border.

Two intelligence officials say two missiles were fired Sunday into a house in Naurak village in North Waziristan, an area dominated by militant groups blamed for launching attacks on American forces across the border in Afghanistan.

The CIA has rained down missiles on houses, bunkers and training centers in the Pakistani region after a bomber killed seven of its employees late last year in Afghanistan.

The intelligence officials say the identity of the people killed in the strike is not yet known.

They spoke on condition of anonymity because they were not authorized to talk to the media.
