RAWALPINDI: At least 30 people were killed Friday when gunmen stormed a mosque in Pakistan's garrison city of Rawalpindi, detonating bombs and shooting at worshippers, the interior minister said.

"There were two suicide bombers and the roof of the mosque collapsed," Interior Minister Rehman Malik told the private ARY television channel.

"According to the information I received a few moments ago, above 30 were killed and there are so many people injured."

Army spokesman Major General Athar Abbas told AFP that the mosque was situated on Parade Lane, an area frequented by military officers.

"More than one terrorist attacked. They exploded bombs inside the mosque.... There were shots fired but we don't know whether it was from the military or the terrorists," he said.

"Terrorists were killed but we don't yet know how many."
