In recent days, Trump and other US officials insisted negotiations with Iran were progressing well, saying Iran had given up any suggestion of tolling vessels transiting through the Strait of Hormuz.

In a Truth Social post on Wednesday, Trump said Iran had informed the US that there would be "no tolls, no insurance costs and no other charges of any kind being sought or received".

"If this is false information, negotiations would end, immediately," he added.

The US has condemned reports that Iran is charging fees to tankers going through the strait, and many see any tolling system as breaking with international maritime law.

On Tuesday, Iranian and Omani officials held talks in Oman's capital of Muscat to discuss "the future management of navigation", although Omani Foreign Minister Badr Al-Busaidi said both countries were committed to "toll-free safe passage".

However, Iran's chief negotiator, Mohammed Bagher Ghalibaf, told state-affiliated news outlets that "everyone should know that the administration of the Strait of Hormuz will never go back to the way it was before the war."

The cargo ship hit by a projectile on Thursday was the Ever Lovely, a Singapore-flagged vessel.

According to British maritime security agency UKMTO, the ship was struck 7.5 nautical miles south-east of Oman's port of Dahit.

The Ever Lovely had been following the UKMTO's recommended route through the strait when it was struck, the ship's owner, Evergreen, said.

"All crew members remain safe as does the vessel itself and all cargo," it added.

In response, the UN's International Maritime Organization (IMO) paused its planned evacuation of more than 11,000 sailors who have been stranded in the key shipping lane since the war erupted.
