Israel said it launched a pre-emptive strikes against Iran on Saturday. The New York Times, citing a US official, reported that US strikes on Iran were underway.
A source told Reuters that Iran’s supreme leader, Ayatollah Ali Khamenei, was not in Tehran and had been transferred to a secure location.
The attack, coming after Israel and Iran engaged in a 12-day air war in June, follows repeated US-Israeli warnings that they would strike again if Iran pressed ahead with its nuclear and ballistic missile programmes.
“The State of Israel launched a pre-emptive attack against Iran to remove threats to the State of Israel,” defence minister Israel Katz said.
An Israeli defence official said the operation had been planned for months in coordination with Washington, and that the launch date was decided weeks ago.
Explosions were heard in Tehran on Saturday, Iranian media reported, and sirens sounded across Israel around 08:15 local time in what the military said was a proactive alert to prepare the public for the possibility of an incoming missile strike.
The Israeli military announced the closure of schools and workplaces, with exceptions for essential sectors, and a ban on public airspace.
Israel closed its airspace to civilian flights, and the airports authority asked the public not to go to any of the country’s airports.
Iran said it was prepared to discuss curbs on its nuclear programme in exchange for lifting sanctions but ruled out linking the issue to missiles.
Tehran also said it would defend itself against any strike.
