Iran TV shows video of commandos capturing a tanker headed for the US.

Iranian navy commandos conducted a helicopter-borne raid to seize a U.S.-bound oil tanker in the Gulf of Oman, footage aired by Iran's state television showed Friday. The capture of the Turkish-managed, Chinese-owned Advantage Sweet represents the latest seizure by Iran amid tensions with the U.S. over advancing nuclear program. The U.S. Navy's 5th Fleet has said the Iranian seizure was at least the fifth commercial vessel taken by Tehran in the last two years. The vessel's manager, a Turkish firm called Advantage Tankers, issued a statement acknowledging the Advantage Sweet was being escorted by the Iranian navy to a port on the basis of an international dispute. All the ship's 24 crew members are Indian.
