Security personnel recovered six bullet-riddled bodies from the Yakagund area of Mohmand Agency on Tuesday.
Official sources said the victims had been shot dead and their bodies were dumped in Yakagund.
The bodies were shifted to District Headquarters Hospital for identification and autopsy.
There was no immediate claim of responsibility for the killings.
Mohmand Agency is one of Pakistan’s seven tribal agencies near the Afghan border which are rife with homegrown insurgents and are said to be strongholds of Taliban and al Qaeda operatives.
