The incident occurred in Maqbal Mata Sangar area of upper Kurram Agency bordering Afghanistan, police said.
Six of a family lost their lives in a landmine explosion in Kurram Agency on Tuesday, Samaa reported.
In October 2017, four security personnel of Frontier Constabulary (FC) were killed and three injured when three improvised explosive devices (IED) went off in an area of Kurram tribal agency.
A Pakistani official says a roadside bomb has killed six members of a family in a tribal region near the Afghan border.
The injured man, Seeda Khan, was shifted to District Hospital in Parachinar for medical assistance.
No group has claimed responsibility for the attack so far, he added. However, tribesmen believe that it was an act of terror.
Hundreds of people become targets of landmines planted by militants against common people and security forces in Pakistan's tribal areas every year.
