The United States launched another wave of strikes on Iran for the third consecutive day early on Tuesday after President Donald Trump announced the reimposition of a blockade on Iranian ports and floated a 20 per cent fee on cargo in the vital Strait of Hormuz.

Trump said a deal with Iran was still possible even as attacks were carried out, with Tehran striking two ships in the Strait of Hormuz and killing one crew member, according to the United Arab Emirates.

Meanwhile, Iran’s Revolutionary Guards Corps (IRGC) said two “offending supertankers” were hit and disabled in the Strait of Hormuz. It said the tankers ignored warnings, turned off navigation systems and tried to pass through a “mined route”.

The statement did not name the vessels or say whether it was referring to the same tankers cited by the UAE’s Ministry of Defence.

The Guards said the US was “inciting vessels to use an illegal route” and warned that cooperation with the “aggressor enemy” would result in damage, delays in reopening the strait and a global energy crisis.
