AFP - US missiles targeted a Taliban training centre in Pakistan's tribal belt Wednesday, killing four militants in the latest strike in a recent spike in drone attacks, Pakistani officials said.

The attack targeted a compound in Sanzali village, about 30 kilometres (19 miles) west of Miranshah, the main town in North Waziristan, and was the fourth suspected US missile attack in the tribal district in a week.

"One US drone fired two missiles. It was a Taliban training centre. We have reports that four militants were killed and five wounded," a Pakistani security official told AFP on condition of anonymity.

Two intelligence officials and a local administration official confirmed the attack and the same death toll.

The identity of the militants was not immediately clear.

The area is a stronghold of Hafiz Gul Bahadur, who fought with the Taliban when US-led troops invaded Afghanistan and is reputed to control up to 2,000 fighters whom he sends across the border but who do not attack in Pakistan.
