Update: The Front Altair, the Marshall Islands flag tanker damaged in Thursday's attacks, has now sunk, according to Iranian television. Later, others denied these reports.

.. If accurate, the sinking could have a serious impact on oil prices and the environment, as the ship contained twice the amount of oil as Exxon-Valdez.

While some sources cited torpedoes as the weapons used in the attacks, another said officials suspected the use of a magnetic mine, similar to the devices used during last month's attacks.
