A Ukrainian drone strike has killed one person and injured another in Russia’s southern Krasnodar region, while also triggering a fire at an oil refinery and damaging critical infrastructure, regional authorities said on Sunday.

Krasnodar Governor Veniamin Kondratyev described the overnight assault as a “massive” drone attack, saying several residential buildings were damaged by falling debris.

“Krasnodar region came under a massive enemy drone attack. Sadly, one person was killed,” Kondratyev said in a statement posted on Telegram.

He added that another person sustained injuries and received medical treatment at the scene.

According to the governor, the attack also sparked a fire at an oil refinery in the region, while a power line and a gas pipeline were damaged.

The affected facility is the Slavyansk-on-Kuban oil refinery, one of the largest refining plants in southern Russia and part of the Slavyansk EKO Group. Located near the Russian-occupied Crimean Peninsula, the refinery has been targeted on several previous occasions since the outbreak of the war.

Russia’s Ministry of Defence said its air defence systems intercepted 213 Ukrainian drones across more than a dozen regions, including the capital, Moscow.

Ukraine has increasingly targeted Russian energy infrastructure as part of its strategy to disrupt Moscow’s military logistics and economic capacity to sustain the war. Kyiv says the strikes are in retaliation for repeated Russian attacks on Ukrainian cities, civilians, and energy facilities.

Russia, meanwhile, has continued to launch near-daily missile and drone attacks across Ukraine since beginning its full-scale invasion in February 2022. The conflict, now in its fifth year, remains the deadliest war in Europe since World War II, with both sides continuing to exchange long-range strikes on military and energy infrastructure.
