DUBAI, United Arab Emirates — Commandos from Iran’s paramilitary Revolutionary Guard rappelled down from a helicopter onto an Israeli-affiliated container ship near the Strait of Hormuz and seized the vessel Saturday, the latest in a series of attacks between the two countries.

The Middle East had braced for potential Iranian retaliation over a suspected Israeli strike earlier this month on an Iranian consular building in Syria that killed 12 people, including a senior Guard general who once commanded its expeditionary Quds Force there.

The Israeli war on Hamas in the Gaza Strip meanwhile is now 6 months old and is inflaming decades-old tensions across the whole region. 

With Iranian-backed forces like Hezbollah in Lebanon and Yemen’s Houthi rebels also involved in the fighting, any new attack in the Mideast threatens to escalate that conflict into a wider regional war.

Iran’s state-run IRNA said a special forces unit of the Guard’s navy carried out the attack on the vessel, the Portuguese-flagged MSC Aries, a container ship associated with London-based Zodiac Maritime.

Zodiac Maritime is part of Israeli billionaire Eyal Ofer’s Zodiac Group. Zodiac declined to comment and referred questions to MSC. 

Geneva-based MSC later acknowledged the seizure and said 25 crew had been aboard the vessel. IRNA said the Guard would take the vessel into Iranian territorial waters.

Earlier, a Middle East defense official, who spoke on condition of anonymity to discuss intelligence matters, shared a video of the attack with the Associated Press. 

In it, the Iranian commandos are seen rappelling down onto a stack of containers sitting on the deck of the vessel.

A crew member on the ship can be heard saying: “Don’t come out.” He then tells his colleagues to go to the ship’s bridge as more commandos come down on the deck. One commando can be seen kneeling above the others to provide them potential cover fire.

The video corresponded with known details of the MSC Aries. The helicopter used also appeared to be a Soviet-era Mil Mi-17 helicopter, which both the Guard and the Iranian-backed Houthis of Yemen have used in the past to conduct commando raids on ships.

The British military’s United Kingdom Maritime Trade Operations described the vessel as being “seized by regional authorities” in the Gulf of Oman off the Emirati port city of Fujairah, without elaborating.

The MSC Aries had been last located off Dubai heading toward the Strait of Hormuz on Friday. The ship had turned off its tracking data, which has been common for Israeli-affiliated ships moving through the region.

The Israeli foreign minister, Israel Katz, called on nations to list the Guard as a terrorist organization.

Iran “is a criminal regime that supports Hamas’ crimes and is now conducting a pirate operation in violation of international law,” Mr. Katz said.

Iran since 2019 has engaged in a series of ship seizures and attacks on vessels have been attributed to it amid ongoing tensions with the West over its rapidly advancing nuclear program.

For days, Iranian officials up to and including Supreme Leader Ayatollah Ali Khamenei have been threatening to “slap” Israel for the Syria strike. Western governments have issued warnings to their citizens in the region to be prepared for attacks.
