Iran’s Islamic Revolutionary Guard Corps claimed responsibility Tuesday for striking navigation equipment on Oman’s small Didamar Island in the Strait of Hormuz. State media reported that the IRGC navy targeted systems it accused of aiding unauthorized ship transits, including those escorted by U.S. forces.

Three sources with knowledge of the matter confirmed to Reuters that navigation and communications systems on the island, also known as Little Quoin Island, came under attack. Video footage showed smoke rising from the area, though the exact source remained unclear. The Institute for the Study of War assessed the strike occurred on November 8, with Iranian claims following on November 10.

Omani officials acknowledged detecting a loud explosion but a senior official stated that the navigation aids had not been struck. Satellite imagery from November 10 revealed no obvious damage to the lighthouse or radio and radar masts, though burn marks appeared earlier.

The incident unfolded against the backdrop of the U.S.-Israeli conflict with Iran that began in late February. U.S. forces have provided escorts for commercial vessels to maintain oil flows through the strait after Iranian attacks reduced traffic. Exporters have turned to ship-to-ship transfers off Oman and the UAE to bypass disruptions.

Shipping analysts said the reported attack on Didamar would likely have limited effect on overall transits because alternative systems remain in place. Iran has repeatedly targeted what it calls unauthorized routes near the Omani coast.

The claims add to ongoing maritime incidents in the region, where at least 130 events have occurred since February and dozens of seafarers have been killed. Both sides continue limited strikes on vessels and infrastructure while broader diplomatic efforts to ease tensions have stalled.
