US officials have confirmed that Israel has carried out military operations against Iran but did not describe those operations.
They said Israel warned the Biden administration earlier on Thursday that the strike was coming in the next 24 to 48 hours.
According to CNN, the Israelis assured their US counterparts that Iran’s nuclear facilities would not be targeted.
Iranian state media has confirmed only that air defence opened fire on drones in Isfahan province, bringing them down.
There were also Iranian reports of air defences working around Tabriz.
