Ukrainian sea drones damaged a Russian Black Sea Fleet patrol ship off occupied Crimea, Kyiv said on Tuesday.

Ukraine’s military intelligence agency said that a unit called Group 13 attacked the Russian Black Sea Fleet patrol ship Sergey Kotov near the Kerch Strait.

“As a result of a strike by Magura V5 maritime drones, the Russian ship Project 22160 Sergey Kotov sustained damage to the stern, starboard and port sides,” it said. The message added that the ship was worth about $65 million (£51million).

Andriy Yermak, President Volodymyr Zelenskiy’s chief of staff, said on Telegram on Tuesday that “The Russian Black Sea Fleet is a symbol of occupation. It cannot be in the Ukrainian Crimea,” in an apparent reference to the attack.
