PESHAWAR (Dunya News / AP) – Three people were killed after a powerful explosion ripped through a small town in the Bajaur tribal region on the border with Afghanistan today (Friday).

Aslam Khan, a government official in the area, told The Associated Press that at least 25 people were also injured in the explosion Friday in Char Mang district of the Bajour tribal region, an unsettled area of northwest Pakistan where Taliban insurgents have carried out numerous attacks.

The injured persons have been moved to Headquarters Hospital in Khar area.

So far no one has claimed responsibility for the explosion but initial reports were that it was remotely detonated. Still details were scarce because of the remoteness of the area, Aslam Khan said.

The incident occurred weeks after the army launched a new operation against militants in another Khyber tribal region in the northwest. The operation aims to prevent insurgents from carrying out cross-border attacks in Pakistan and neighboring Afghanistan.

The Pakistani military has undertaken several operations in the tribal regions in recent years and at one point claimed it had cleared the areas. But militants still swiftly move across the porous border to regroup and stage new attacks.
