The death toll in a suicide bombing in northwestern Pakistan on Friday rose to 25, a regional official said, with 30 wounded during the attack on a packed mosque.

As Reuters reported, a portion of the mosque and veranda collapsed in the blast and fell on worshippers.

 “We are still retrieving bodies and the injured from rubble of the mosque building,” deputy administrator of Mohmand Agency Naveed Akbar said.

As it was reported earlier, a suicide bomber who broke into a mosque during Friday prayers, blew himself up. So far nobody has undertaken responsibility for terrorist attack.
