Ukraine has launched strikes on Russian energy sites. Russian authorities and media said on Sunday that drone debris set fire to a fuel storage facility in the Rostov region, and civilian infrastructure was reported damaged in Saratov province. Ukraine has increased attacks on Russia’s oil and gas facilities, saying they fund Moscow’s invasion. Meanwhile, Kyiv denied Russian claims that a Ukrainian drone struck the Russian-occupied Zaporizhzhia nuclear plant. Russia's state nuclear energy company accused Ukraine of a deliberate attack. The Zaporizhzhia plant has repeatedly come under fire since Russia's full-scale invasion began in February 2022.
