Islamabad - At least three people were killed and half a dozen injured on Friday as a US drone attacked a house in Pakistan's tribal area along the Afghan border.
A security official said a pilotless US drone fired missiles at a house in Mohmmad Khel village in North Waziristan.
More casualties were feared as some people were believed to be buried under the rubble, said the official, who spoke on condition of anonymity.
However, a spokesman from the Pakistan Army denied the report saying the US planes only hit targets on Afghan side of the border.
