The identities of those killed in the strike were not immediately known but officials suspect that they were of Afghan origin.
Wednesday’s drone strike was first attack in the area during the month. At least six people were killed following a US drone strike on a seminary linked to the Haqqani Network in Khyber Pakhtunkhwa provine last month.
