Russia’s Admiral Makarov warship has been hit by Ukrainian missiles and burst into flames, according to Ukrainian officials.

The frigate would be Russia’s latest high-profile naval loss in a troubled campaign, coming after reports that US intelligence helped Ukraine locate and sink the Russian warship Moskva weeks ago.

The Makarov was said to have been sailing close to Snake Island in the Black Sea south of Odesa.

Ukrainian presidential adviser Anton Gerashchenko reported on his Telegram page that the Admiral Makarov was hit by a Ukrainian Neptune anti-ship missile. He cited Russian sources.

Russian navy ships stationed in Crimea were sent to help Admiral Makarov, he added.
