A spate of blasts recorded across the Mediterranean on tankers that have recently called at Russian ports has security analysts concerned about a new form of attack targeting merchant shipping. Two Thenamaris aframax tankers – the Seajewel and the Seacharm – have both reported explosions onboard in the past month in the Mediterranean, while the Grace Ferrum product tanker has also been badly hit off Libya, all suffering similar damage – holes in hulls below the waterline, leading to some security analysts to suggest the vessels were targeted with limpet mines. In late December, the Russian Ursa Major general cargo ship sank in the Mediterranean between Spain and Algeria after an explosion. Away from the Mediterranean, the Turkish-owned Koala tanker, laden with 130,000 tonnes of heavy fuel oil, was about to set off from the Russian port of Ust-Luga when three explosions ripped through the rear of the ship on February 9, forcing the crew to evacuate. googletag.cmd.push(function() { googletag.display('div-gpt-ad-1_95_0_1_2'); }); TagsGreece Italy Libya Russia Spain Turkey
