Ukraine war briefing: Russian oil hub of Tuapse hit for fourth time as environmental disaster mounts

Ukrainian drones struck Russia's Tuapse oil refinery and Black Sea port on Friday for the fourth time in 16 days, according to Ukraine's SBU security service, causing toxic black smoke and oil slicks along the coastline as Russian authorities reported clearing over 13,300 cubic metres of contaminated fuel and soil. The attack compounds an environmental crisis at the strategic Russian oil export hub while Ukraine simultaneously faces Russian drone barrages—Russia launched approximately 410 drones on Friday, of which Ukraine's air force said it downed or neutralised 388 across multiple regions.
