ATHENS, April 18 (Reuters) – Merchant vessels attempting to cross the Strait of Hormuz on Saturday received radio messages from Iran’s navy telling them they were not ​allowed to pass, while two ships reported being hit ‌by gunfire, shipping sources said.

Several commercial vessels tried to transit the strait after receiving a notice to mariners a day earlier saying passage would be allowed but restricted to lanes Iran deemed safe.

On Saturday, ‌at ​least two ships reported that Iranian boats ⁠fired shots, shipping and ⁠maritime security sources told Reuters. The incidents were reported in waters between the Qeshm and Larak islands. The vessels turned back without completing the crossing, the sources said.

The ​United Kingdom Maritime Trade Operations (UKMTO) agency said it had received a report of an incident 20 nautical miles northeast ⁠of Oman. The captain of a ⁠tanker said it had been approached by two ​Islamic Revolutionary Guard Corps gunboats that fired on the vessel. ​The tanker and its crew were safe.

A container ship ‌was also hit by gunfire, a maritime security source said.

Some vessels reported that Iran’s navy had been broadcasting a VHF message saying the Strait of Hormuz was closed again.

“Attention all ⁠ships, regarding the failure of the U.S. government to fulfil its commitment in the negotiation, Iran declares the Strait of Hormuz completely ⁠closed again. No ‌vessel of any type or nationality is ⁠allowed to pass through the Strait of ​Hormuz,” the ‌radio message said.

Hundreds of ships and about ​20,000 seafarers ⁠remain stranded in the Gulf, waiting to pass through the key waterway, which handles about 20% of global oil and liquefied natural gas flows.
