MIRANSHAH (AFP) - A US drone strike targeting a compound in tribal belt on Monday killed at least 10 suspected militants, local security officials said. The unmanned aircraft fired four missiles, hitting the compound and a vehicle parked in the Gorwaik area of Datta Khel town, 45 kilometres west of Miranshah, the main town in North Waziristan tribal district, a senior official based in Peshawar told AFP. Two missiles struck the compound and another two hit a vehicle, the official said. At least 10 militants were killed in this American drone attack. A second security official based in Miranshah confirmed the death toll. Both officials said the number of casualties could rise as the area of the drone strike had been completely destroyed. A total of 20 US drone strikes have now been reported in Pakistans tribal belt since US commandos found and killed Al-Qaeda chief Osama bin Laden in a unilateral airborne raid on the Pakistani garrison city of Abbottabad on May 2.
