A US drone strike on Saturday killed at least three persons in Pakistan's restive tribal region near the Afghan border, security officials said.The strike took place in the Datta Khel area of North Waziristan. The drone targeted a moving vehicle and fired two missiles, they said."The identity of the victims was immediately unclear but this area is mostly occupied by members of the militant commander Gul Bahadur's group," a security official in Peshawar told AFP.Another official on the ground in Miranshah said that the vehicle had been driving through a village 35 kilometers (around 20 miles) west of Miranshah, the headquarters of North Waziristan tribal district."We have reports that two militants of Gul Bahadur group were also injured in the attack," he told AFP on the condition of anonymity because he was not authorised to speak to the media. Witnesses told that drones continued hovering over the area even after the strike that triggered fear among the residents. The strike came at a time while the Pakistani foreign minister is paying a visit in the United States. Saturday's U.S. drone strike is the 29th of its kind (counted on daily basis) in Pakistan since 2012. So far this year, a total of 213 people have reportedly been killed in such strikes.
