What we know so far about Israel’s strike on Iran

• US officials have confirmed that Israel has carried out military operations against Iran. The officials said Israel warned the Biden administration earlier on Thursday that a 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 reported that air defence batteries had been activated after reports of explosions near a major airbase close to the city of Isfahan. The Iranian government appeared to play down the scale of the attack, with a senior commander in Iran’s army saying there was no damage in Isfahan, according to state TV.

• Isfahan is home to sites associated with Iran’s nuclear programme, including its underground Natanz enrichment site. State television described all sites in the area as “fully safe” and the UN nuclear watchdog, the International Atomic Energy Agency (IAEA), confirmed there was no damage to any nuclear sites.

• The airbase close to Isfahan has long been home to Iran’s fleet of American-made F-14 Tomcats – purchased before the 1979 Islamic Revolution.
