The statement came as AFP journalists heard a renewed series of loud blasts and air raid sirens over Jerusalem, after the military said earlier that it had identified multiple missile barrages launched from Iran.

"The strike (on Iran) targeted dozens of military targets and was carried out as part of a broad, coordinated, and joint operation against the regime," the Israeli army said in a statement.

"In the months preceding the strike, close and joint planning was conducted between the IDF and the US military, enabling the execution of the broad strike in full synchronisation and coordination between the two militaries," it added.

The military said the strikes were part of operation "Roaring Lion", which it said aimed to "thoroughly degrade the Iranian terrorist regime and to remove existential threats to the State of Israel over time".

In a later separate statement, the army said the Israeli air force was striking a number of Iranian military sites in the country's western region.

"The Israeli Air Force is currently conducting a broad strike on a number of military targets belonging to the Iranian regime in western Iran," the Israeli military said in a statement.

A statement from Israel's Magen David Adom emergency services just before 11:00 am (0900 GMT) said that no reports of impact had been received.

"MDA teams were dispatched to treat several individuals who were injured on their way to protected areas, as well as people suffering from anxiety," it said.
