Strait of Hormuz and diplomatic efforts
The IRGC's navy said two oil tankers struck sea mines on Saturday while trying to pass through the Strait of Hormuz. In a statement carried by Iran's state news agency IRNA, it said the vessels had switched off their navigation and tracking systems and were using what it called an "unauthorised" route.
The IRGC said two other tankers turned back towards the Gulf after receiving warnings from its maritime traffic control centre.
Diplomatic efforts to stop attacks and reopen the Strait of Hormuz remain stalled. Iran's parliamentary speaker and chief negotiator, Mohammad Bagher Ghalibaf, told Al Jazeera that Tehran wanted to move beyond a state of "no war, no peace". Ghalibaf said Iran has conveyed seven conditions for a deal through a Qatari mediator and was awaiting an official US response. The conditions he outlined included lifting the US naval blockade and sanctions, releasing frozen Iranian funds, ending hostilities on all fronts and formally declaring the war over.
US President Donald Trump's administration has tightened sanctions and maintained the blockade on Iranian ports.
