One vessel was “allegedly struck by a blast,” which caused the fire that then spilled over to another ship, an official with the Russian Maritime and River Transport Agency said.
Clouds of black smoke can be seen billowing over a vessel engulfed by a blaze on YouTube footage, which shows the scene of the incident. Another ship can be seen floating nearby.
Some three dozen sailors managed to escape the burning ships by jumping off the vessels. At least 11 people died in the incident and 12 have so far been rescued from the sea.
