The US Central Command said its forces began launching “self-defence” strikes against Iran on Wednesday morning (AEST).

US president says Iran shot down a helicopter in the Strait of Hormuz, adding that his country will 'respond'.

In a statement posted to social media, U.S. Central Command said the strikes would be “a proportional response to unjustified Iranian aggression.”

The US military says the two crew members were rescued by a sea drone and are in stable condition.

Trump has repeatedly said Iran wants to make a deal with him to end the war and that they have agreed to concessions.
