President Volodymyr Zelensky posted a video showing the sea drones striking the sterns of the vessels.

The tankers were in the waters near the port of Novorossiysk in Russia.

This is the third successful attack by Ukrainian sea drones in the past week.

Earlier, two of the uncrewed vessels struck a sanctioned tanker southeast of Russian city of Tuapse.

The next day, Ukrainian Navy struck two Russian patrol boats guarding the Kerch Bridge, which connects occupied Crimea with Russian territory.

And in an attack by air, Ukrainian drones struck Primorsk Sunday, Russia's largest oil-exporting port on the Baltic Sea, sparking a fire.
