Russia Says It Thwarted Another Attack on the Kerch Strait Bridge

The Russian military said Saturday that it had thwarted another attack on a critical bridge linking the occupied Crimean Peninsula to Russia that Kyiv has vowed to keep attacking until it is unusable.

The Russian Ministry of Defense said that three Ukrainian “semi-submersible unmanned boats” targeting the Kerch Strait Bridge were destroyed in the Black Sea overnight. The first maritime drone was detected shortly before midnight and the other two launched about 10 minutes apart just after 2 a.m. local time, the ministry said in statements.

The claims could not be independently verified, and Ukraine’s military did not explicitly comment Saturday on whether its drones had targeted the bridge.

But Ukrainian officials have said that they consider the destruction of the vital 12-mile-long bridge a strategic priority, and Kyiv’s forces have repeatedly targeted it.

Last month, Russia’s Defense Ministry said it had shot down two Ukrainian missiles targeting the Kerch Strait Bridge. And in July, predawn explosions hit the bridge in what the Russian Defense Ministry claimed was a Ukrainian attack using maritime drones. While that strike inflicted far less damage than an explosives-laden truck that detonated along a key stretch of the bridge in October, it exposed the vulnerability of the bridge — and other Russian supply routes far from the front — as Ukraine wages a grueling counteroffensive in the country’s south and east.

The head of Ukraine’s Security Services, Vasyl Malyuk, has confirmed that Kyiv was behind the October attack.

Britain’s Defense Ministry said on Friday that Russia had deployed a “range” of measures — including smoke generators, air defense systems and an “underwater barrier of submerged ships” — to “minimize damage” from future attacks on the Kerch Strait Bridge.

“The bridge’s importance for both logistics and symbolism of Russian occupation mandates these extensive protection measures,” it said in an intelligence update.

Ukraine has been racing to expand its fleet of maritime drones to counter Russian naval dominance on the Black Sea. In October it used naval drones to attack the Russian fleet at Sevastopol, a Crimean port, though it is not clear how much damage was done. Russia has also repeatedly accused Ukraine of launching aerial attack drones over occupied Crimea.

At the same time, Ukraine in recent weeks has intensified its frequency of drone attacks in Russia. A wave of exploding drones was launched in six regions of Russia this past week, damaging four military cargo planes at an airfield, in an apparent sign that Ukraine was increasingly capable of striking back deep inside Moscow’s territory.

American officials have said that the drone attacks in Russia are intended to demonstrate to the Ukrainian public that Kyiv can still strike back, even as its counteroffensive to reclaim Russian-occupied territory moves at a grinding pace. Another objective, as top Ukrainian officials have said, is to bring the war home to the people of Russia.
