A fire broke out in an oil refinery in southern Russia, 200 miles from the border with Ukraine, following a drone strike, local authorities have said. The blaze at the Lukoil site in Volgograd comes amid reports of Kyiv stepping up its targeting of energy facilities in Russia. Volgograd regional governor Andrey Bocharov said on Telegram that Russian air defenses and electronic warfare (EW) systems had "repelled a drone attack" in the region overnight on Friday. As a result, "one drone fell and set off a fire at the Volgograd oil refinery."
