Two intelligence officials say a suspected U.S. missile strike has killed two people in Pakistan's North Waziristan tribal region.

The Saturday strike was the sixth in about a week in the area. Two missiles fired by a suspected unmanned drone hit a house in Data Khel, an area that is a stronghold of the Haqqani militant network.

The intelligence officials say three people have also been wounded. They spoke on condition of anonymity because they were not authorized to release the information.

The Haqqani network is suspected of involvement in a Dec. 30 attack on a CIA base in eastern Afghanistan that killed seven Americans.
