Russia's patrol ship "Sergey Kotov" thwarted an attack of two Ukrainian drone boats overnight and neutralized them, the Russian Defense Ministry (MoD) said on Tuesday.
"Last night, using two unmanned boats, the Ukrainian armed forces unsuccessfully tried to attack patrol ship 'Sergey Kotov' of the Russian Black Sea Fleet that is controlling ship traffic in the southwestern part of the Black Sea (370 kilometers [230 miles] southwest of Sevastopol)," the ministry said in a statement.
On Monday, a total of 11 drones were shot down and suppressed by means of electronic warfare in the skies over the Republic of Crimea.
