PESHAWAR (AFP) A US drone on Monday fired two missiles at a vehicle carrying militants in Datta Khel, near the Afghan border, killing five rebels, officials said. The strike occurred at Khar Qamar, a village in Datta Khel area, and was the fourth drone attack in the past four days, a senior security official in the area told AFP. The US drone fired two missiles at the militants vehicle, killing five rebels, he said. He said nationalities of the militants killed in the strike were not immediately known. A senior local administration official also confirmed the strike and casualties. US forces have been waging a drone war against Taliban and Al-Qaeda-linked commanders in Pakistans northwestern tribal belt. The US military does not as a rule confirm drone attacks, but its armed forces and the Central Intelligence Agency operating in Afghanistan are the only forces that deploy pilotless drones in the region. More than 1,040 people have been killed in 121 drone strikes in Pakistan since August 2008. However, the attacks fuel anti-American sentiment in the country.
