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.

Despite recent progress in peace talks between Russia and Ukraine, the two nations continue trading fire via missile and drone attacks.

A Ukrainian drone was shot down near Russia’s Kursk Nuclear Power Plant, sparking a transformer fire that cut reactor output but did not raise radiation levels.
