The U.S. military has stopped another merchant vessel trying to break through the American blockade of Iranian ports.

Axar.az reports, citing The Associated Press, the Gambia-flagged bulk carrier Lian Star ignored multiple warnings from U.S. forces overnight as it tried to enter an Iranian port, the official, who spoke on condition of anonymity to discuss military operations, said. The ship was disabled by U.S. aircraft in the Gulf of Oman and remains adrift there, the official said, adding that U.S. forces have not boarded it.

With the latest action, U.S. military has stopped six ships trying to breach the blockade. One was allowed to proceed.
