The Exilenova+ Telegram channel reported that the vessel had previously operated in the Novorossiysk area and the Black Sea and had sailed under the Russian flag.
An attack on the port of Sochi was reported earlier.
The extent of the damage to the vessel and the consequences of the reported attack remain unclear.
