A blast in Tirah Valley in Jamrud tehsil of Khyber Agency left five people dead and three others injured.
The explosion took place in the house of a suspected terrorist.
The scenic Tirah Valley has long been plagued by a turf war between rival extremist groups. The fighting has forced thousands of tribesmen out of the valley. Many of them are now sheltering in Peshawar and other tribal regions bordering Khyber Agency.
In January, ten people, including three members of the outlawed Lashkar-e-Islam, were killed when a mortar shell exploded in the the Dars Jumat area of the same valley.
