MIRANSHAH, Pakistan - A US drone missile strike killed at least three militants in Pakistan's North Waziristan tribal district along the Afghan border on Friday, Pakistani security officials said.

Two missiles were fired at Machi Khel village, around 30 kilometres (20 miles) east of Miranshah, the main town in the district that is considered the biggest fortress of Taliban and Al-Qaeda militants in Pakistan.

Senior security officials said the target was a vehicle but two local intelligence officials said the target was a house in the village.

"At least three militants were killed. The US drone fired two missiles. The target was a vehicle," one of the senior officials told AFP.

Local security officials said the missiles destroyed a house and put the death toll at five.
