The crew and vessel were safe, according to the United Kingdom Maritime Trade Operations DUBAI, United Arab Emirates: An explosion struck an Israeli-owned cargo ship sailing out of the Middle East on Friday, renewing concerns about ship security in the region amid escalating tensions between the US and Iran. The crew and vessel were safe, according to the United Kingdom Maritime Trade Operations, which is run by the British navy. The explosion in the Gulf of Oman forced the vessel to head to the nearest port. Dryad Global, a maritime intelligence firm, identified the stricken vessel as the MV Helios Ray, a Bahamian-flagged roll-on, roll-off vehicle cargo ship. Another private security official, who spoke to The Associated Press on condition of anonymity to discuss intelligence matters, similarly identified the ship as the Helios Ray. Satellite-tracking data from website MarineTraffic.com showed the Helios Ray had been nearly entering the Arabian Sea around 0600 GMT Friday before it suddenly turned around and began heading back toward the Strait of Hormuz. It was coming from Dammam, Saudi Arabia, and still listed Singapore as its destination on its tracker. The blast comes as Tehran increasingly breaches its 2015 nuclear accord with world powers to create leverage over Washington. Iran is seeking to pressure Biden to grant the sanctions relief it received under the deal that former President Donald Trump abandoned nearly three years ago. Capt. Ranjith Raja of the data firm Refinitiv told the AP that the Israeli-owned vessel had left the Arabian Gulf Thursday bound for Singapore. On Friday at 0230 GMT, the vessel stopped for at least nine hours east of a main Omani port before making a 360-degree turn and sailing toward Dubai, likely for damage assessment and repairs, he said. While details of the explosion remained unclear, two American defense officials told the AP that the ship had sustained two holes on its port side and two holes on its starboard side just above the waterline in the blast. The officials said it remained unclear what caused the holes. They spoke to the AP on condition of anonymity to discuss unreleased information on the incidents. A United Nations ship database identified the vessel’s owners as a Tel Aviv-based firm called Ray Shipping Ltd. Calls to Ray Shipping rang unanswered Friday. Abraham Ungar, 74, who goes by “Rami,” is the founder of Ray Shipping Ltd., and is known as one of the richest men in Israel. He made his fortune in shipping and construction. According to the Nikola Y. Vaptsarov Naval Academy, where Ungar provides support and maritime training, he owns dozens of car-carrying ships and employs thousands of engineers. The US Navy’s Bahrain-based 5th Fleet said it was “aware and monitoring” the situation. The US Maritime Administration, an agency of the Transportation Department, issued a warning to commercial shippers early Saturday acknowledging the explosion and urging ships to “exercise caution when transiting” the Gulf of Oman. While the circumstances of the explosion remain unclear, Dryad Global said it was very possible the blast stemmed from “asymmetric activity by Iranian military.”
