PESHAWAR: A US drone attack late Sunday killed at least five militants in northwest Pakistan's South Waziristan tribal district, officials said.

“Five militants were killed in the strike,” a military official told AFP. “The target was a house used by militants,” he added, requesting anonymity.

An intelligence official who confirmed the attack put the toll at six dead and three wounded.

The unmanned aircraft fired three missiles at the house in Kaza Panga village, 15 kilometres (10 miles) west of Wana, the main town in lawless South Waziristan.

The attack was the first since a US gunman shot and killed two Pakistanis in the eastern city of Lahore on January 27, triggering a diplomatic row between Pakistan and the United States.
