With the US threatening further strikes, Iran accused Washington of hitting a wedding party, killing four people and wounding dozens. Its health minister later said 18 people in total had been killed and 108 injured in the latest wave of US strikes.
The US military said it struck air defences, radar systems, maritime assets, mine-laying capabilities and communications sites on Tuesday. Iran reported hits on multiple targets near the Strait of Hormuz.
Iran struck what it said were US assets in Bahrain, Jordan, Kuwait and Iraq, and said its aim was now to drive US forces from the vast network of military bases they have maintained for decades across the Middle East.
The flare-up threatens to deepen a conflict that has dragged on since the US launched strikes on Iran in February, disrupting global energy supplies.
