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 is one of two Russian ships with a crew of 29 on board that suffered severe damage in the Black Sea, authorities in Russia said.
At least one crew member was reportedly killed. The second ship was said to have drifted after sustaining damage.
The incident occurred in the Kerch Strait, which separates Russia from Crimea, the Ukrainian peninsula that Moscow illegally annexed in 2014.
