Ukraine launched a drone attack on Russia on Sunday, forcing a sharp fall in the capacity of a reactor at one of Russia’s biggest nuclear power plants and sparking a huge blaze at the major Ust-Luga fuel export terminal, Russian officials said.

Despite talk of peace by Russia and Ukraine, the deadliest European war since World War Two is continuing along the 2,000 km (1,250 mile) front line accompanied by missile and drone attacks deep into both Russia and Ukraine.

Russia’s defence ministry said at least 95 Ukrainian drones had been intercepted across more than a dozen Russian regions on August 24, the day that Ukraine celebrates its declaration of independence from the Soviet Union in 1991.

The Kursk nuclear power plant, just 60 km (38 miles) from the border with Ukraine, said that air defences shot down a drone that detonated near the plant just after midnight, damaging an auxiliary transformer and forcing a 50% reduction in the operating capacity at reactor No. 3.

Radiation levels were normal and there were no injuries from the fire which the drone sparked, the plant said. Two other reactors are operating without power generation and one is undergoing scheduled repairs.

The United Nations’ nuclear agency, the International Atomic Energy Agency, said it was aware of reports that a transformer at the plant caught fire due to military activity and stressed that every nuclear facility should be protected at all times.

A thousand km north, on the Gulf of Finland, at least 10 Ukrainian drones were downed over the port of Ust-Luga in Russia’s northern Leningrad region, with debris sparking fire at the Novatek-operated terminal – a huge Baltic Sea fuel export terminal and processing complex, the regional governor said.
