A Russian oil tanker carrying thousands of tonnes of oil products split apart during a heavy storm on Sunday, spilling oil into the Kerch Strait, while another tanker was also in distress after sustaining damage, Russian officials said.
The vessels were in the Kerch Strait between mainland Russia and Crimea, which Russia annexed from Ukraine in 2014, when they issued distress signals.
Russian investigators opened two criminal cases to look into possible safety violations after at least one person was killed when the 136-metre Volgoneft 212 tanker, with 15 people on board, split in half with its bow sinking.
Footage on state media showed waves washing over its deck.
The Russian-flagged vessel, built in 1969, was damaged and had run aground, officials said.
An unverified video posted on Telegram showed some blackened water on stormy seas and a half-submerged tanker.
The second Russian-flagged ship, the 132-metre Volgoneft 239, was drifting after sustaining damage, the Emergencies Ministry said. It has a crew of 14 people and was built in 1973.
