Ukraine claimed Tuesday it has sunk another Russian warship in the Black Sea using high-tech sea drones as Kyiv’s forces continue to take aim at targets deep behind the war’s front line. Russian authorities did not confirm the claim.

The Ukrainian military intelligence agency said a special operations unit destroyed the large patrol ship Sergey Kotov overnight. The ship, which Ukraine said was commissioned in 2021 and was hit near the Kerch Strait, reportedly can carry cruise missiles and around 60 crew.

The sinking of such a modern ship would be a significant loss and an embarrassing blow for Moscow, even though there are dozens of other vessels in its Black Sea fleet.

Patrol boats such as the Sergey Kotov are part of Russia’s countermeasures against drone attacks, according to an article published last month by the Foreign Policy Research Institute, a US think tank. The vessels use radar and a helicopter to detect and destroy drones using grenade launchers and heavy machine guns, it said.

Kyiv's forces are struggling to keep the better-provisioned Russian army at bay at some points along the largely static 1,500-kilometer (930-mile) front line, but are also taking aim at targets far beyond the battlefield.

In the Black Sea, Ukrainian successes against enemy warships have pushed the Russian fleet away from the coast, allowing Ukraine to set up a grain export corridor.

The Ukraine defense ministry posted on X, formerly Twitter, a video of what it said was the nighttime attack on the Sergey Kotov using Magura V5 uncrewed vessels that are designed and built in Ukraine and laden with explosives. Seven Russian crew members were killed and six were injured in the strike, while 52 crew were rescued, the military intelligence agency said.

The Ukrainian claims could not immediately be independently verified, and disinformation has been a feature of the fighting that broke out after Russia’s full-scale invasion of its neighbor in February 2022.

The private security firm Ambrey said the attack took place at the port of Feodosia, in Crimea, which Russia annexed in 2014. Ambrey said it has seen footage taken by a crew member on a merchant vessel in the port, showing the Sergey Kotov firing at the drones.

The ship was hit at least twice, with the second strike resulting in a large blast, Ambrey reported.

Last month, Ukraine claimed it twice sank Russian warships using drones. On Feb. 1, it claimed to have sunk the Russian missile-armed corvette Ivanovets, and on Feb. 14 it said it destroyed the Caesar Kunikov landing ship. Russian officials did not confirm those claims.

Kyiv officials say some 20% of Russian missile attacks on Ukraine are launched from the Black Sea, and hitting Russian ships there is embarrassing for Moscow.

Almost two years ago, the flagship of Russia’s Black Sea fleet, the Moskva guided-missile cruiser, sank after it was heavily damaged in a missile attack.

North Korean leader Kim Jong Un supervised tests of short-range ballistic missile systems that simulated nuclear counterstrikes against US and South Korean forces, state media said Friday, as the North continued to blame its rivals for escalating tensions through their joint military exercises.

The report came a day after South Korea’s military detected multiple launches from North Korea’s eastern coast and assessed that the tests could also be related to the country’s weapons exports to Russia during its war in Ukraine.

North Korea’s official Korean Central News Agency said Thursday’s tests involved a mobile ballistic missile system apparently modeled after Russia’s Iskander, as well as 600-millimeter multiple rocket launchers that South Korean officials classify as ballistic due to their self-propulsion and guided flight. Both are part of a growing lineup of weapons systems that the North says could be armed with “tactical” nuclear weapons for battlefield use.

KCNA said the tests were intended to train military units operating missile and rocket systems to more effectively execute attacks under the North’s nuclear weapons control system and ensure a swift response to a nuclear crisis.

The agency criticized the United States and its “vassal states” for expanding joint military exercises on and around the Korean Peninsula, which the North claims are preparations for nuclear war, and said Thursday’s launches demonstrated the “rapid counteraction posture” of its forces.

Kim stressed the need to strengthen the role of his nuclear forces in both deterring and fighting war, and called for continued efforts to improve combat readiness and precision strike capabilities, KCNA said.

South Korea’s Joint Chiefs of Staff said multiple missiles of various types were launched from the area around the eastern port city of Wonsan on Thursday from about 8:10 to 9:20 a.m., with the farthest traveling about 800 kilometers (497 miles).

Lee Sung Joon, spokesperson for the Joint Chiefs, said in a briefing the North Korean launches were possibly intended to test the performance of weapons it plans to export, as the country continues to send military equipment and troops to fuel Russia’s warfighting against Ukraine.

Japanese Defense Minister Gen Nakatani told reporters that none of the North Korean missiles reached Japan’s exclusive economic zone and there was no damage to vessels or aircraft in the area.

It was the North’s first known ballistic activity since March 10, when it fired several ballistic missiles hours after US and South Korean troops began an annual combined military exercise, and the country’s sixth launch event of the year.

Tensions on the Korean Peninsula have escalated in recent months as North Korean leader Kim continues to accelerate the development of his nuclear and missile program and supply weapons and troops to support Russia’s war against Ukraine.

Thursday’s launch came a day after North Korean state media said Kim urged munition workers to boost the production of artillery shells amid his deepening alignment with Moscow.
