On Tuesday there was an attempted hijacking of a tanker in the Gulf of Oman. According to the UK Maritime Trade Operations (UKMTO), nine armed men boarded a Panama-flagged tanker before leaving several hours later – reportedly after the ship’s crew sabotaged the vessel’s engines. The UK believes this attempted hijacking was the latest in a string of maritime attacks perpetrated by Iran or one of the several militant groups it backs in the Middle East.
