MIRANSHAH: A US drone strike in northwest tribal belt on Thursday killed 22 suspected militants, security officials said, as the covert campaign ramps up in the border region.
Two missiles hit Datta Khel town, some 40 kilometres (25 miles) west of Miranshah, the main town in North Waziristan tribal district.
"A US drone fired two missiles and destroyed a house. 22 suspected militants were killed in the attack," a senior security official in Peshawar said.
