#ABC: Israel attacks Iran, sources say, drones reported over Isfahan

Israel has attacked Iran, three people familiar with the matter said, as Iranian state media reported early on Friday that its forces had destroyed drones, days after Iran launched a retaliatory drone strike on Israel.
One source told Reuters the U.S. was not involved but was notified by Israel before the attack.
Iran's Fars news agency reported three explosions were heard near an army base in the central city of Isfahan. An Iranian official told Reuters there was no missile attack and the explosions were the result of the activation of Iran's air defense systems.
