The Russian Ministry of Defense reported the information.
According to the ministry, Russian air defense systems intercepted and destroyed 35 UAVs over Russian territory.
Specifically, 4 drones were reportedly shot down over the Moscow region, 17 over the Krasnodar region, 3 each over the Belgorod and Kursk regions, 4 over the Yaroslavl region, 2 over the Kaluga region, and one each over the Oryol and Rostov regions.
In Slavyansk-on-Kuban, explosions were heard during the night, followed by a fire at one of the city's facilities.
According to ASTRA, one person died from a heart attack after the explosions. There were no casualties from the fire, and the settlement is not under threat.
Local authorities reported the fire at the Slavyansk Refinery was completely extinguished around 03:30 a.m.
Later, Ukrainian media outlets cited sources as saying that the Security Service of Ukraine, together with the Special Forces and the Unmanned Systems Forces of the Ukrainian Armed Forces, were involved in the attack on the oil refinery in Russia's Krasnodar Territory.
"We can already talk about a successful outcome - a large fire was recorded in the area of atmospheric columns, which were the main target," the source said.
The source added that the Security Service continues to implement a strategy to undermine Russia's economic potential and reduce the flow of oil dollars that Russians send to the war.
In general, the Security Service’s drones have recently successfully attacked 12 oil refineries in Russia.
