Iranian media said an under-construction nuclear power plant in the south-western city of Darkhoveyn had been struck as well as Qeshm Island in the Strait of Hormuz. Centcom said it also targeted Iran's Revolutionary Guards (IRGC) responsible for the attack that killed two US troops in Jordan on Friday, where another service member remains missing. Iran has carried out its own strikes, with Kuwaiti officials saying an electricity and water plant had been hit for the second time in two days. Bahrain said air defences had intercepted an attack. The US and Iran have ramped up attacks against each other in recent days, with both sides accused of striking critical infrastructure. Washington has also reimposed its blockade of Iranian ports and Tehran has declared the Strait of Hormuz closed, as their preliminary ceasefire collapsed less than a month after it began. On Sunday the IRGC said two vessels had ignored Iranian warnings not to transit the Strait of Hormuz and were consequently involved in "an accident". It warned that all vessels that are "influenced" by the US and "use unsafe routes" will "certainly face accidents". Also on Sunday, the US embassy in Amman said Jordanian authorities had evacuated the international airport and seaport in the southern city of Aqaba due to a "specific and credible threat". (BBC)
