At least seven killed in blast at Pakistan religious school

The police have confirmed the death of at least seven people and more than 50 injured, after an explosion during a class at a religious school in Pakistan.

The attack took place in the northern city of Peshawar.

Hospital officials say that those killed in the attack were aged between 20 and 30.

Dozens of others were injured, including four under the age of 13.

Earlier reports suggested four of the dead were children, but this has since been retracted.

The city of Peshawar, close to the Afghan border, has seen some of the worst of the violence during the Taliban insurgency in recent years.
