Ukraine accuses Moscow of recklessness due to risk of ecological damage as second tanker runs aground

A Russian tanker carrying more than 4,000 tonnes of oil products has sunk in the Black Sea amid stormy conditions while a second has run aground, threatening an ecological disaster.

The cargo ship Volgoneft-212 snapped in half on Sunday after being hit by a large wave. Video showed its bow end sticking vertically out of the water. The boat got into difficulties off the east coast of occupied Crimea, 5 miles (8km) from the Kerch strait, Russian media reported.
