PESHAWAR: A US drone strike killed four suspected militants Tuesday and destroyed a rebel compound in tribal area 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.
Tuesday's 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 suspected militant compound, killing four militants," a Pakistani security official said on condition of anonymity.
