The Ukrainian Navy said that it struck a Russian special unit located on an oil rig near Crimea overnight on Tuesday.
The strikes killed a Russian anti-tank crew and destroyed reconnaissance and surveillance equipment at the Syvash drilling rig in the Black Sea.
A post from the Ukrainian Navy’s telegram stated that the Russian army tried to frame the attack as a failure.
“Attempting to portray another defeat as a victory, the Russians are spreading a video allegedly showing the destruction of a Ukrainian Navy boat with a 'Lancet' munition,” the post read.
However, the navy stated that it had actually struck with a suicide drone.
Ukraine, Russia trade attacks on energy infrastructure
Syvash is an oil rig that can drill wells up to 3.7 miles deep. It’s one of the Ukrainian state gas and oil company’s Boiko Towers, which have been occupied by Russia since 2014.
The Telegraph reported that Russia has used them to monitor Ukrainian activity in the Black Sea between Crimea and Odesa.
Earlier this week, Ukraine said its drones struck Tuapse, one of Russia's main Black Sea oil ports, causing a fire and damaging at least one ship, as part of Kyiv's efforts to undermine Russia's war economy by targeting its energy infrastructure.
The regional administration confirmed the strike sparked a fire at the port.
Ukraine has for several months been striking Russian oil refineries, depots, and pipelines, while Ukrainian energy infrastructure has also been the target of Russian strikes in a war that is approaching its fourth year.
