The US has said it struck Iranian military sites over the weekend while Tehran said it responded by targeting an American base, marking the third known escalations in a week around the Strait of Hormuz.

US Central Command (Centcom) said it launched "self-defence strikes" in response to "aggressive Iranian actions", which it said included a US drone being shot down over international waters.

Iran's Islamic Revolutionary Guard Corps (IRGC) said it had targeted an air base used by US forces for an attack on southern Iran.

Trump urged his critics to "sit back and relax" in a post on Truth Social early on Monday, saying it would "all work out well in the end". He said Iran "really wants to make a deal, and it will be a good one for the USA".
