  • Dozens of sea mammals have been found dead since last month’s Russian oil tanker spill in the Black Sea, a dolphin rescue centre said as authorities raced to contain the disaster. The spill began on 15 December, when two ageing Russian tankers were caught in a storm off the Kerch Strait linking Crimea to southern Russia. One sank and the other ran aground, pouring about 2,400 tonnes of a heavy fuel oil into the surrounding waters, authorities estimate. Russia’s Delfa centre, which rescues and rehabilitates dolphins, said on Sunday it had recorded 61 dead cetaceans – a type of aquatic mammal that includes whales, dolphins and porpoises – since the incident.
