Iran claims strike on an Omani island in the Strait of Hormuz, says tanker navigation gear there was helping 'the enemy'

Iran's Revolutionary Guard says it struck Didamar Island, a small Omani island in the Strait of Hormuz, going after radar and radio equipment that guides oil tankers along the strait's southern route, Fox News reports.

Three sources confirmed to Reuters on Wednesday that navigation and communications equipment on the island, also known as Little Quoin Island, had been attacked. Iranian state television claimed the people and equipment on the island "were helping the flow of oil smuggling by the enemy." Video published by Reuters showed smoke rising near the rocky outcrop. Fox News reports the attack followed US strikes on Iran's Qeshm Island.

The Institute for the Study of War says the strike happened Nov. 8, two days before Iranian state media claimed it. ISW says the extent of the damage is unclear, and commercial ships kept using the southern route afterward.

That southern route runs through Omani waters, outside Tehran's direct military control, and is overseen by CENTCOM. US forces keep a blockade on Iranian ports and escort commercial ships through the strait. Didamar is uninhabited and sits about 10 nautical miles north of Oman's Musandam Peninsula. It has had a lighthouse since 1914 and a radar tower used to steer traffic through the narrow passage.
