Guardian – Conflicting reports have emerged from Iran over an explosion heard in the central city of Isfahan, close to the country’s sensitive nuclear facilities. Iran’s semi-official Isna news agency quoted a judiciary official in Isfahan, saying that an explosion had been heard. “We heard a sound similar to that of an explosion but we have received no reports about its causes and the consequences so far,” said Gholamreza Ansari, in quotes carried by Isna. He said the explosion did not appear to be of any significance.
