Police say a bomb explosion at a video shop has killed three people and wounded three in northwestern Pakistan.

Police official Abdul Rauf said the attack happened in the town of Kohat on Wednesday. He said the dead and injured had been transported to a hospital.

There was no immediate claim of responsibility. Previous bombings in this volatile region have been blamed on pro-Taliban militants who consider music and movies to be offensive to Islam.

Kohat lies about 45 miles south of Peshawar, the capital of North West Frontier Province bordering Afghanistan.
