New Delhi : The world has its fingers crossed as Iran’s state media has reported explosions in the Isfahan province, days after Iran’s drone attack on Israel sparked fears of a major escalation in West Asia.While Israel authorities have not confirmed a strike and Iran state-media, too, has downplayed claims of an attack on a military site, US media has quoted officials saying that Israel had carried out retaliatory strikes.Iran’s Fars news agency reported early on Friday that “three explosions” were heard near Shekari army airbase in the northwest of Isfahan province, news agency AFP reported. Hossein Dalirian, spokesperson for the Iran’s space agency, said several drones had been shot down and there had been “no missile attack for now”. An unnamed US official has told CNN that the target was not nuclear. Iran’s Tasnim news agency, which has links with the Islamic Revolutionary Guard Corps, reported that nuclear facilities in Isfahan are “completely secure”. Tasnim also denied that Iran had been attacked from abroad.The International Atomic Energy Agency confirmed there is “no damage” to Iran’s nuclear sites. “DG @rafaelmgrossi continues to call for extreme restraint from everybody and reiterates that nuclear facilities should never be a target in military conflicts. IAEA is monitoring the situation very closely,” a statement said.
