A Russian marine biologist was drowned, and an Italian badly hurt, when the research vessel on which they were working was rammed by a cargo ship and sank off the coast of Sicily on 3 August. The ship, Thetis, was measuring marine biomass around seven kilometres off the island's coast when it was struck by the Heleni, a 55,000-tonne Panamanian container ship. It was morning, and the weather was foggy.
