Russia-Ukraine war: List of key events, day 1,257

A Russian attack killed three people in Ukraine's southeastern Zaporizhia region on Sunday, Governor Ivan Fedorov wrote on Telegram. A Ukrainian drone attack sparked a major fire at an oil depot in Sochi in southern Russia, the governor of Russia's Krasnodar region, Veniamin Kondratiev, said on Sunday. The fire was extinguished hours later after 120 firefighters were deployed, officials said. Russia's civil aviation authority, Rosaviatsia, briefly halted flights at Sochi's airport during the fire. Ukraine's military says it used drones to target several sites inside Russia, including refineries, an airfield and an electronics plant.
