Iran seized two container ships seeking to exit the Gulf via the Strait of Hormuz on Wednesday after firing on them and another vessel, in its first seizures since war with the United States and Israel began in February.Iran's semi-official Tasnim news agency reported the seizures and added its Revolutionary Guard Corps Navy had also warned that any disruption to order and safety in the strait would be considered a "red line".Ships Fired UponThe IRGC accused the seized ships, the Panama-flagged MSC Francesca and Liberia-flagged Epaminondas, of operating without required permits and tampering with their navigation systems.

At least three container ships were hit by gunfire in the Strait of Hormuz on Wednesday, maritime security sources and the United Kingdom Maritime Trade Operations (UKMTO) said.Iran has imposed restrictions on ships using the strait, first in retaliation for the U.S.-Israeli bombardment of the country, and then in response to a U.S. blockade of Iranian ports.A Liberia-flagged container ship sustained damage to its bridge after being hit by gunfire and rocket-propelled grenades northeast of Oman.The UKMTO said the master of the vessel reported being approached by an IRGC gunboat. The vessel, it said, was subsequently fired upon.

Fraudulent messages promising safe passage through the Strait of Hormuz in exchange for cryptocurrency have been sent to some shipping companies whose vessels are stranded west of the waterway, Greek maritime risk management firm MARISKS has warned.The U.S. has maintained its blockade of Iranian ports, while Iran has lifted and then re-imposed its blockade of the Strait of Hormuz, through which roughly a fifth of the world's oil and liquefied natural gas passed before war broke out in the Middle East.Amid ceasefire talks, Tehran, which controls the chokepoint, has proposed tolls on vessels to safely transit.

Concerns grew on Monday that the ceasefire between the United States and Iran might not hold after the U.S. said it had seized an Iranian cargo ship that tried to run its blockade and Iran vowed to retaliate.Efforts to build a more lasting peace in the region likewise appeared to be on shaky ground, as Iran said it would not participate in a second round of negotiations that the U.S. had hoped to kick off before the ceasefire expires on Tuesday.The U.S. has maintained a blockade of Iranian ports, while Iran has lifted and then reimposed its own blockade on marine traffic passing through the Strait of Hormuz, which typically handles roughly one-fifth of the world's oil supply.The U.S.

Safe and sustainable passage through the Strait of Hormuz is what top shipping companies require before the world's sees much oil or cargo leave or enter the Gulf, two top sector executives said on Wednesday."Two weeks ago when the ceasefire, said to be temporary, came into picture, we thought there was hope. But in reality, the agreement was not translated into the safety and passage (of the vessels)," Jotaro Tamura, chief executive of Japan's Mitsui O.S.K. Lines, told Reuters in an interview on the sidelines of the Singapore Maritime Week conference.MOL is one the world's largest shipping companies and the top owner of oil and liquefied natural gas tankers.
