Ukraine's military intelligence (GUR) said on February 1 that sea drones attacked and sank a Russian corvette in the Black Sea near Crimea overnight. The GUR said on Telegram that Russia's Ivanovets was patrolling near Lake Donuzlav in the western part of Crimea when several drones hit the ship.
A video posted on the site appears to show explosions hitting a ship, which then appears to start sinking. The GUR claim could not be independently verified. Russian officials have not commented. Ukraine has staged a string of damaging attacks on the Crimean Peninsula, which Russia illegally annexed from Ukraine in 2014. To read the original story by RFE/RL's Ukrainian Service, click here.
