On the 11th (local time), the twelfth day of the war between the United States and Israel and Iran, four ships were attacked in the Strait of Hormuz area. Iran's Islamic Revolutionary Guard Corps (IRGC) said it was responsible for two of them.

The Revolutionary Guard said it struck the Liberia-flagged cargo ship Express Room, owned by an Israeli company, on the morning of the same day and brought the vessel to a stop, stating, “It sailed while ignoring warnings from the Revolutionary Guard Navy.”

The Revolutionary Guard also announced that it attacked the Thai-flagged container ship Mayuri Nari after it ignored warnings and attempted to transit the Strait of Hormuz.

The ship caught fire after being struck. According to the Thai Navy, 20 crew members evacuated in lifeboats, and the Omani Navy rescued and transferred them. The remaining three are being rescued.

On the same day, in waters 25 nautical miles (about 46.3 km) northwest of Ras Al Khaimah in the United Arab Emirates (UAE), the Japan-flagged container ship One Majesty was hit by an unidentified projectile. According to Japanese media, there were no injuries, and no flooding, fire, or oil spill occurred. It was also reported that navigation was unaffected.

Another vessel that came under attack was identified as a bulk carrier 50 nautical miles (about 92.6㎞) northwest of Dubai, UAE. According to maritime risk management firm Vanguard, the ship is the Marshall Islands-flagged Star Guiness, and while the hull was damaged, all crew members are safe.

The Revolutionary Guard stressed, “All ships seeking to pass through the Strait of Hormuz must obtain permission from Iran.”

The Strait of Hormuz is where roughly 20% of the world's crude oil shipments pass. As Iran has effectively closed the strait, the passage of ships carrying Middle Eastern crude and petroleum products has been halted.

Since the outbreak of the war on the 28th of last month, the number of vessels attacked in and around the Strait of Hormuz has risen to at least 15.

Khatam al-Anbiya, the central military headquarters that oversees the Iranian armed forces, issued a statement on state TV the same day, threatening that “any vessel belonging to the United States, Israel, or their allies, or carrying oil cargo from these countries, will be regarded as a legitimate target.”

It added, “You cannot keep oil and energy prices low by artificial means,” and warned, “Oil prices depend on regional security, which you have destabilized, so prepare for 200 dollars a barrel.”
