KOHAT: A bomb blast in a camp for internally displaced persons in Hangu left seven people dead and 13 injured on Sunday.

The Mohammad Khawaja camp houses IDPs from Orakzai Agency. A girl was among those killed and three children among the injured.

Police quoted witnesses as saying that the bomb was rigged to a motorcycle parked outside a shop in the camp.

District Police Officer Anwar Saeed Kundi and DSP Hangu Falak Naz said that six kilograms of explosives had been used in the blast.

Officials said that soon after the blast a heavy contingent of police arrived at the camp and cordoned off the area. Kohat-Hangu road was closed by bomb disposal personnel for clearing the area.

Families displaced from Orakzai Agency have been living in the camp for six years. The army has claimed to have cleared 90 per cent of the agency, but the IDPs are reluctant to leave the camps for fear of militants returning to their areas.
