Iran fires missiles at Israel, warns US of retaliation after airstrikes

Iran fired a salvo of missiles and drones on Monday at Israel while also warning the United States that its military has been given a free hand to attack American targets in the wake of the Trump administration's massive strikes on Iranian nuclear sites.

Israel said its defence systems were operating to intercept the threat, apparently targeting north and central areas, and told people to head to shelters. Iran described the attack a new wave of its Operation True Promise 3, saying it was targeting the Israeli cities of Haifa and Tel Aviv, according to Iranian state television. 

There were no immediate reports of damage.

The attack came the day after the United States inserted itself into Israel's war by attacking Iranian nuclear sites, prompting fears of a wider regional conflict.

Iran said the US had crossed a very big red line with its risky gambit to strike the three sites with missiles and 30,000-pound bunker-buster bombs.

On Monday, Iranian Gen Abdolrahim Mousavi, the chief of joint staff of armed forces, warned Washington its strikes had given Iranian forces a free hand to "act against US interests and its army.

Mousavi described the American attack as violating Iran's sovereignty and being tantamount to invading the country, the state-run IRNA news agency reported.

In the wake of the American attacks on Iran, calls came from across the globe for de-escalation and the return to diplomacy to try and resolve the conflict. 

On Monday, the European Union's top diplomat said the bloc remained very much focused on the diplomatic solution.

The concerns of retaliation and this war escalating are huge, Kaja Kallas said at the start of a foreign ministers' meeting in Brussels where Iran has jumped to the top of the agenda.

Especially closing of the Strait of Hormuz by Iran is something that would be extremely dangerous and not good for anybody, Kallas said, referring to a maritime route crucial for oil transport.

After Sunday's attacks, Iranian officials repeated their longtime threats of possibly closing the key shipping lane.

Iranian Foreign Minister Abbas Araghchi was meeting on Monday in Moscow with Russian President Vladimir Putin, one of Iran's key allies.
