The video appears to show the sinking of a Russian tanker

Footage released by Russia’s Southern Transport Prosecutor’s Office shows a Russian oil tanker broken in half and sinking amid a severe storm, with streaks of oil visible in the water.

The ship was one of two Russian ships with 29 crew members on board that were seriously damaged in the Black Sea, Russian authorities said.

At least one crew member was reportedly killed. The second ship is said to have drifted away after sustaining damage.

The incident occurred in the Kerch Strait, which separates Russia from Crimea – the Ukrainian peninsula illegally annexed by Moscow in 2014.
