A South Korean ship sailing near the Strait of Hormuz was attacked on Monday, according to the Korean media outlet Chosun Daily, citing a government official.
Earlier on Monday, the outlet quoted an official from the South Korean Foreign Affairs Ministry saying that the Korean government was still verifying the attack.
"We have initially confirmed that there have been no casualties among our nationals as of the first check," the official said.
Trump said Iran fired shots at the cargo ship and some other targets as the US launched an operation seeking to open the Strait of Hormuz to shipping. He urged South Korea to join that effort.
The fire broke out in the engine room of the Panama-flagged cargo ship, where 24 crew members, including six Korean nationals, were on board, a HMM spokesperson told Reuters, adding that the cause of the fire was not clear at the moment.
Fire extinguished, ship to be towed to Dubai port
The South Korean shipper confirmed on Tuesday that the fire had been extinguished.
The ship will be towed to a nearby port in Dubai, the company said, adding no casualties have been reported so far.
Earlier on Monday, an American official confirmed to The Jerusalem Post that Iran's navy did not hit a United States Navy ship near the Strait after the Iranian Islamic Revolutionary Guard Corps (IRGC)-aligned Fars News Agency claimed that two missiles had hit a US naval frigate near the port of Jask at the Strait's southern entrance.
In addition, Iran has prepared other scenarios that it will activate "if necessary," according to Iran's Tasnim News Agency, citing an unnamed source.
Over the past few months, Iran has repeatedly claimed to have struck several US naval ships operating in the region, including the USS Abraham Lincoln aircraft carrier in early March.
CENTCOM: US ships successfully transited Strait
US Central Command (CENTCOM) said in a X/Twitter post that two US-flagged ships successfully transited the Strait on Monday.
CENTCOM earlier confirmed that no US ship had been hit, adding that "US forces are supporting Project Freedom and enforcing the naval blockade on Iranian ports."
"The missiles launched didn’t even come close," added CENTCOM.
