"So far, there are seven dead and 30 injured receiving hospital treatment," the official IRNA news agency quoted Qadami as saying.

The quake's epicentre was near Borazjan, around 60 kilometres (35 miles) from Bushehr, where Iran has its reactor which has been generating the electric power since its inauguration in 2011.
