PESHAWAR A US drone strike killed four militants Tuesday and destroyed a rebel compound in Pakistans lawless tribal badlands along the Afghan border, local security officials said.

Pakistani officials say unmanned US aircraft have significantly stepped up attacks on Taliban and Al-Qaeda-linked operatives in the semi-autonomous region this month, recording at least 21 attacks in September.

Tuesdays strike took place in Zeba village close to the Afghan border and west of Wana, the main town in South Waziristan.

“A US drone fired two missiles which hit a militant compound, killing four militants,” a Pakistani security official told AFP on condition of anonymity. Another security official confirmed the attack and the death toll. -AFP
