An oil tanker caught fire after striking naval mines east of the Strait of Hormuz, the Iranian Navy said Tuesday.

In a statement, the Navy said the tanker had switched off its tracking systems and attempted to pass through a “restricted and unsafe” area before hitting the mines, The Caspian Post reports, citing Anadolu Agency.

The vessel sustained damage and caught fire following the incident, according to the statement.

The Navy did not disclose the tanker’s identity, flag, crew details or whether there were any casualties.

It said the Strait of Hormuz remained “unsafe and closed” to vessels attempting to transit without coordination.

The Navy added that ships seeking safe passage through the strait must coordinate with Iran’s armed forces.

The incident comes amid diplomatic efforts to end the conflict involving Iran and the United States, as regional countries seek to facilitate negotiations and ease tensions.

Türkiye, Saudi Arabia, Pakistan and Iran have also maintained diplomatic contacts on regional security, including discussions aimed at reducing tensions and supporting efforts toward a lasting settlement.

Washington and Tehran signed a memorandum of understanding in June and began negotiations, which later collapsed over disagreements concerning navigation through the Strait of Hormuz, a strategic waterway for energy supplies and other goods.
