TEHRAN - Iran on Wednesday said it had struck several US bases in the region in retaliation for the latest wave of US attacks on Iran, further straining the ceasefire after Iran and Israel traded missile attacks in a recent major escalation.

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.”
