At least 10 people have died in a fire that broke out onboard two cargo ships in the Black Sea near Crimea on Monday night, according to Russia’s state news agency TASS.

Crew members jumped into the frigid sea to escape the flames, which probably began during a fuel transfer. Search teams have so far rescued at least 14 people and continue to look for the missing, Russia’s transport ministry told Reuters.

The two Tanzanian-flagged ships, named Candy and Maestro, had 31 crew members onboard, including Turkish and Indian citizens.

Both ships reportedly remain ablaze.

According to Reuters, the conditions were stormy on the Kerch Strait at the time of the incident.
