DUBAI, United Arab Emirates — Attackers seized a tanker linked to Israel off the coast of Yemen on Sunday, authorities said. While no group immediately claimed responsibility, it comes as at least two other maritime attacks in recent days have been linked to the Israel-Hamas war.

The attackers seized the Liberian-flagged Central Park, managed by Zodiac Maritime, in the Gulf of Aden, the company and private intelligence firm Ambrey said. An American defense official, speaking on condition of anonymity to discuss intelligence matters, also confirmed to The Associated Press that the attack took place.

Zodiac called the seizure “a suspected piracy incident.”

“Our priority is the safety of our 22 crew onboard,” Zodiac said in a statement. “The Turkish-captained vessel has a multinational crew consisting of a crew of Russian, Vietnamese, Bulgarian, Indian, Georgian and Filipino nationals. The vessel is carrying a full cargo of phosphoric acid.”

Zodiac described the vessel as being owned by Clumvez Shipping Inc., though other records directly linked Zodiac as the owner. London-based Zodiac Maritime is part of Israeli billionaire Eyal Ofer’s Zodiac Group. British corporate records listed two men with the last name Ofer as a current and former director of Clumvez Shipping, including Daniel Guy Ofer, who is also a director at Zodiac Maritime.

It wasn’t immediately clear who was behind the attack. Nearby Aden is held by forces allied to Yemen’s internationally recognized government and a Saudi-led coalition that has battled Yemen’s Iranian-backed Houthi rebels for years. That part of the Gulf of Aden in theory is under the control of those forces and is fairly distant from Houthi-controlled territory in the country. Somali pirates also are not known to operate in that area.

The U.S. defense official said that it appeared “an unknown number of unidentified armed individuals” seized the ship.

“U.S. and coalition forces are in the vicinity and we are closely monitoring the situation,” the official said.

Ambrey said that it appeared that “U.S. naval forces are engaged in the situation and have asked vessels to stay clear of the area.”

Zodiac Maritime has been targeted previously amid a wider yearslong shadow war between Iran and Israel. In 2021, a drone attack assessed by the U.S. and other Western nations to have been carried out by Iran killed two crew members aboard Zodiac’s oil tanker Mercer Street off the coast of Oman.

The British military’s United Kingdom Maritime Trade Operations, which provides warnings to sailors in the Middle East, had earlier issued a warning to sailors that “two black-and-white craft carrying eight persons in military-style clothing” had been seen in the area. It issued another warning saying that radio traffic suggested a possible attack had occurred before acknowledging the seizure.
