“The identities of those killed in the strike are not yet known,” the official said on condition of anonymity.
“There are still four drones flying over Datta Khel,” he said.
A second security official confirmed the strike which took place in Sunzalai village near Datta Khel, a town 45 kilometres (28 miles) west of Miranshah, the main town in North Waziristan — a renowned hot-bed of Taliban and Al-Qaeda linked militants.
Six missiles were fired at the compound and vehicle, injuring another five militants, a local security official said.
The compound belongs to a local tribesman, the official said.
