Pakistani intelligence officials say the latest suspected U.S. missile strike along the Afghan border has killed 15 people, including seven alleged foreign militants.

The officials say the strike involved five drones and 10 missiles, a massing of resources that suggests the U.S. had homed in on a high-profile target.

The missiles Thursday hit two compounds in the Ambarshaga area of the North Waziristan tribal region. It was the second such strike of the day in the Pakistani territory.

The two officials spoke on condition of anonymity because they were not authorized to speak to media.

The U.S. rarely confirms such strikes. Pakistan protests them, but is believed to secretly aid them.
