PESHAWAR: A home-made bomb ripped through a music shop in the northwestern Pakistani city of Peshawar yesterday injuring 20 people.

The blast happened in the Musafir CD Centre located in the basement of a busy shopping centre.

The roof of the shop collapsed in the bombing, Peshawar.

A doctor at a nearby hospital said 20 people were injured, five of them seriously.

The bomb had apparently been placed in a water cooler inside the shop.

The owner of the shop had been receiving threats from suspected militants to close his "un-Islamic" business.

Islamic militancy is spreading in the deeply-conservative province where militants, emulating the Taliban, strive to impose their own strict brand of Islam.
