Russia accused Ukraine of launching multiple drone attacks on Sunday, targeting critical infrastructure.
A drone strike near the Kursk nuclear power plant damaged an auxiliary transformer, leading to a 50 per cent reduction in operating capacity at reactor No. 3, though radiation levels remained normal and there were no injuries from the fire that the drone sparked.
A separate significant blaze erupted at the Novatek-operated Ust-Luga fuel export terminal in Russia's Leningrad region after it was reportedly hit by Ukrainian drones.
Drone activity resulted in temporary flight suspensions at several Russian airports, including Pulkovo.
Ukrainian drones also attacked an industrial enterprise in Syzran, with Ukraine stating its strikes target infrastructure crucial to Russia's military efforts.
