Ukraine strikes Russian oil facilities
The Security Service of Ukraine's Alpha unit claimed responsibility for the operation, which also reportedly damaged three Russian naval ships in Crimea.
Moscow responded with a massive 219-drone assault on Ukrainian territory, leaving 380,000 consumers without power in the north.
The escalating 'energy war' comes as both sides seek to cripple each other's economic and military logistics.
Ukrainian officials stated the strikes are a routine part of their plan to weaken Russia's joint operations capabilities.
