Pakistani intelligence officials say suspected U.S. drone strikes, hours apart, have killed at least five militants in a northwestern tribal region near Afghanistan.

Two intelligence officials say the first attack hit a vehicle in the village of Datta Khel in North Waziristan, killing two militants late on Wednesday. They say two missiles were fired by an American drone.

They said two more missiles flattened a militant compound and killed three militants in the same region early on Thursday. The officials spoke on condition of anonymity because of they were not authorized to talk to media.

In June, the Pakistani military launched a major offensive in North Waziristan — a known stronghold for domestic and foreign militants — to target insurgents responsible for attacks on both sides of the Pakistan-Afghanistan border.
