At least seven people have been confirmed dead and more than 50 injured in a blast at a Pakistani religious school. The victims were now 20-30 years old.

No group has claimed responsibility yet. An investigation has been launched.

Earlier it was reported that four of the dead were children, but since then it has been taken back.

The worst incidents of violence during the Taliban insurgency have occurred in the town of Peshawar, near the Afghan border.

Years back, armed men stormed a city military school, killing more than 150 people, including many children.
