Commandos from Iran’s paramilitary Revolutionary Guard rappelled down ropes from a helicopter onto an Israeli-affiliated container ship in the Gulf of Oman near the Strait of Hormuz and seized the vessel April 13. This was the latest in a series of attacks between the two countries. A special forces unit of the Guard’s navy carried out the attack on the vessel, a Portuguese-flagged container ship associated with London-based Zodiac Maritime. The Strait of Hormuz is the narrow mouth of the Persian Gulf through which a fifth of all globally traded oil passes. Fujairah, on the United Arab Emirates’ eastern coast, is a main port in the region for ships to take on new oil cargo, pick up supplies or trade out crew. According to reports, the waters off Fujairah have been subjected to a series of explosions and hijackings since 2019.
