US Central Command (Centcom) said it launched "self-defence strikes" in response to "aggressive Iranian actions", which 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 Iran. Centcom said two Iranian ballistic missiles targeting US forces in Kuwait had been intercepted and "no American personnel were harmed". Kuwait earlier said its forces had confronted "hostile" missiles and drones. US president Donald 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". The strikes mark the latest exchange between the two sides after negotiations on a deal to end their months-long war failed to advance over the weekend, with US media reporting Trump had requested changes to its terms. The changes are related to the Strait of Hormuz shipping channel and the removal of highly enriched uranium from Iran, the BBC's US news partner CBS News reported. The White House did not respond to a request for comment. (BBC)
