The officials said a pair of missiles hit a moving vehicle in Pir Kali village. The area is home to a mix of Afghan and Pakistani Taliban.
The two Pakistani officials spoke on condition of anonymity because they were not authorized to talk to the media, a Dawn report has said.
The US has ramped up its officially unacknowledged drone attacks in Pakistan's lawless border region, launching over 100 missile strikes this year. (ANI)
