Ukrainian drones targeted a fuel depot in Russia's Yaroslavl region on Sunday. Both Russian and Ukrainian sources confirmed the attack. Kyiv emphasized that the target was located more than 700 kilometers from the Ukrainian border. In addition, a chemical plant in the Tula region, near Moscow, was also hit. The strikes represent a significant extension of the range of Ukrainian operations. These attacks target critical infrastructure deep within Russian territory. The operation underscores Ukraine's growing capability to strike distant targets.
