Attacks on Russian oil refineries
Ukraine has been regularly targeting Russian oil refineries with long-range drones since late January.
At least 13 strikes on Russian refineries have been recorded, said Ukraine's SBU Security Service.
Oil extraction and processing in Russia have decreased by 12% after the strikes.
Revenue from oil product exports accounts for one-third of the Russian budget and a substantial portion of the military budget, SBU Chief Vasyl Maliuk said.
