Explosions shook the Iranian city of Isfahan on Monday, but officials deny the blasts had anything to do with the nuclear facility located there. Isfahan is best known for the presence of the plant that converts uranium into nuclear fuel that went online in 2004. Although the government has attributed the loud blasts to “military maneuvers,” local residents report a different story. But officials insist that because the nuclear plant is under IAEA supervision, the nuclear watchdog organization’s Vienna headquarters would know if there had been an explosion. The incident comes only two weeks after a senior nuclear scientist and 20 others were killed in an explosion at another nuclear facility. Officially, that incident was attributed to an accident while munitions were being transferred, although some blame it on Israeli sabotage.
