Blasts heard on Monday around Iran's Bushehr nuclear power plant were the result of an air defense exercise to increase the defense system's abilities, the political and security deputy to the Bushehr governor told Iran's semi-official Fars news agency.
"This exercise took place at 5 AM local time (1.30 AM GMT) with full preparation and coordination with the armed forces," Mohammadtaqi Irani told Fars.
