Iran warns of 'everlasting consequences'
Despite international calls for Iran not to escalate the conflict in the Middle East, Tehran is furious following US strikes.
Iran's foreign minister Abbas Araghchi warned that the US strikes "will have everlasting consequences" and that Tehran "reserves all options" to retaliate.
Speaking today, he said the US and Israel had "blown up" any chance of nuclear negotiations and asked: "How can Iran return to something it never left, let alone blew up?"
He's also called for condemnation of the attacks from the UN Security Council at an emergency meeting.
Levels of retaliation
Iran's Revolutionary Guard has already said it launched 40 missiles at Israel this morning, including its biggest ballistic missile, the Khorramshahr-4.
Missile hits were reported at sites in northern and central Israel, including in Haifa, Ness Ziona, Rishon LeZion and Tel Aviv.
The Iranian parliament is also moving to close the Strait of Hormuz, according to Iranian state-owned media.
This move that would have global ramifications by disrupting the flow of large amounts of oil and gas, as well as other trade.
Direct retaliation against the US could include attacks on US bases, warships and aircraft in the region, though Iran's ability to launch missiles and drones has been severely degraded by Israeli strikes over the last two weeks.
