Editor's note: This is a developing story.
A patrol ship from Russia's Black Sea Fleet, Sergey Kotov, was hit and destroyed in an overnight attack orchestrated by Ukraine's military intelligence agency (HUR), the agency said on March 5.
Reports of the attack on the Russian vessel came after nighttime explosions on the occupied peninsula, amid which the Kerch Bridge was shut down. The Russian Defense Ministry claimed that 38 drones had been destroyed over Crimea.
Several Ukrainian media outlets reported earlier today that the Russian vessel was hit by Ukrainian naval drones.
According to Ukraine's military intelligence, the ship suffered damage to its stern and on its left and right sides. Sergey Kotov was reportedly located near the Kerch Strait when it was attacked by domestically-produced Magura V5 naval drones.
"The cost of the sunken ship is about $65 million," the agency wrote.
According to the statement, the operation was carried out in cooperation with Ukraine's Navy and the Digital Transformation Ministry.

Andrii Yusov, a military intelligence spokesperson, told Radio Free Europe/Radio Liberty (RFE/RL) that the fate of the ship's crew is being clarified.
"There are killed and wounded, but there is a possibility that some of the crew managed to evacuate," he noted.
The Russian Defense Ministry did not comment on the reported attack.
Sergey Kotov has already reportedly been hit by naval drones along with another patrol ship, the Vasiliy Bykov, in September 2023. The Russian Ministry of Defense claimed that the vessels allegedly managed to repel the attack.
In total, Russia's Black Sea Fleet has four vessels of this design, which the Ukrainian Navy calls "the most modern:" Vasily Bykov, Pavel Derzhavin, Sergey Kotov, and Dmitry Rogachev. Only the latter has not been attacked during the all-out war.
Such ships can perform various tasks at sea, including guarding base points, Ukrainian navy spokesman Dmytro Pletenchuk told RFE/RL, saying that their destruction can have a significant impact.
Sergey Kotov is one of a number of Russian ships reported by Kyiv to have been hit. On Feb. 14, the Russian landing ship Caesar Kunikov was sunk in the Black Sea after being attacked by Ukrainian naval drones.
As of now, only five Ropucha-class landing ships remain in service in Russia's Black Sea Fleet out of a previous total of 13, Ukrainian Navy spokesperson Dmytro Pletenchuk said.
Ukraine has repeatedly struck Russia's Black Sea fleet since the beginning of the full-scale invasion, including the sinking of the flagship cruiser Moskva in April 2022 and a devastating missile attack on the fleet's headquarters in occupied Crimea that reportedly killed more than 30 officers.
