Iran's Mehr news agency said sounds heard on Qeshm Island and at Bandar Abbas port were caused by the disposal of explosive remnants of war.

President Trump told Fox on May 30 the US and Iran are close to a 'very good deal' and he expects a 'better deal,' but said he would ask the Pentagon to intervene if no agreement is reached. He warned that if he does not get what he wants 'we will end it another way.' Trump said a signed accord would secure navigation through the Strait of Hormuz and prevent Iran from acquiring nuclear weapons, and added he is not rushing negotiations: 'If you rush you don't get a good deal.'

Australian Deputy Prime Minister and Defence Minister Richard Marles confirmed on the 31st that Australia will be unable to purchase newly built US Virginia-class nuclear submarines under the prior procurement agreement and will instead receive US in-service Virginia-class boats. Under the US-UK-Australia trilateral security partnership (AUKUS), Canberra had planned from the 2030s to acquire two US in-service Virginia-class submarines plus one newly built, improved Virginia-class boat. Marles said the adjustment will age Australia’s submarine fleet but could relieve pressure on US shipbuilding capacity.
