An explosion in a mosque in southern Iran that killed at least 10 people on Saturday was not an attack and was probably caused by negligence, a police official was quoted as saying on Sunday by a state television station.
"The blast may have been caused by explosives left behind from an earlier exhibition commemorating the (1980-88) Iran-Iraq war," said the English-language Press TV. Iranian media said at least 10 people died in the blast in the southern city of Shiraz and more than 160 were wounded.
According to Reuters, state television urged people in Shiraz to donate blood for the injured and said that all nurses in the city had been called to report for work. The official IRNA news agency said the bomb exploded during an address by a cleric in the Shohada mosque in Shiraz.
