Iran’s news agency acknowledged the seizure after a video seen by The AP showed the commandos raiding the ship, an attack a Mideast defense official attributed to Iran.

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.

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

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