Tehran has said it will pursue military and diplomatic efforts to press Washington over reopening the Strait of Hormuz. Iran's security chief, Mohsen Rezaei, said on Sunday that the shuttle system is now an explicit target for Iran.
The waterway, through which roughly a fifth of global oil and gas flowed before the war, has been largely closed to shipping following Iranian attacks since the US and Israel launched strikes on Iran on February 28. The US Navy has reportedly opened a route allowing Gulf states to export oil and other commodities amid an energy crisis.
Rezaei claimed that US Central Command, with the assistance of the UAE military, has been using smaller vessels to transfer oil to larger tankers, and that Iran has been striking five or six participating vessels nightly for weeks.
"You are smuggling, but the strait is under Iran's control, and we manage it," he said, in remarks seen as a taunt aimed at President Donald Trump, who has hailed energy exports that at times have reached pre-war levels. Trump recently turned down Tehran's proposal to reopen the strait.
Rezaei appeared to signal Iran wants lasting authority over Hormuz and promised a harsh response if Iran's energy and civilian infrastructure were attacked again. He also warned that US-linked cables, data centres and artificial intelligence facilities in the UAE and around the Strait of Hormuz could be targeted, with the threats appearing aimed at Arab regional states.
