The June 18 attack was the second strike on the Moscow Oil Refinery in three days, with industry sources saying it damaged refining units, pipelines and fuel‑storage tanks at a plant that helps supply fuel to Moscow and the surrounding region. Russia said it downed hundreds of drones across multiple regions, but several reached their targets and ignited large fires at the site. Kyiv says strikes on refineries, export terminals and pipelines are intended to cut energy revenues that fund Russia’s invasion, a campaign Western analysts say has tightened conditions in Russia’s fuel market without yet crippling exports. Moscow has continued missile and drone attacks on Ukrainian cities and energy infrastructure in parallel with the refinery strikes. Ukraine also secured more than $4 billion in fresh military pledges at the latest meeting of the Ukraine Defense Contact Group, and the EU formally opened the first cluster of accession negotiations with Kyiv in mid‑June.
