PESHAWAR: At least seven people died and 11 others were injured in a blast at displaced persons' camp in Khyber Pakhtunkhwa's Tog Sarai area of Hangu.

The injured were immediately taken to District Headquarters Hospital for treatment.

Police sources said Sunday the bomb explosion occurred inside Mohammad Khawaja IDPs camp bazaar where the tribesmen from Orakzai Agency were residing.

Deputy Superintended of Police (DSP) Hangu Falak Nawaz told Dawn that the explosion was caused by a remote controlled improvised explosive device (IED).

The explosive was planted on a motorcycle, District Police Officer (DPO) Anwar Saeed Kundi added.

Security personnel were immediately sent to the site.

Hangu, racked by sectarian violence, had been on the frontline of a seven-year-long Taliban insurgency borders the semi-autonomous Federally Administered Tribal Areas (Fata).

It also borders the northwestern tribal region of Orakzai, one of Pakistan's seven lawless districts on the Afghan border considered to be the hub of Taliban and Al Qaeda-linked militants.
