Ukraine's military struck two Russian oil distribution facilities in the Bryansk and Samara regions overnight, Kyiv's general staff said on Tuesday. In Samara, the military hit a line production station that mixes Russian oil for its flagship Urals oil grade for export, the general staff said on Telegram. In Bryansk, it hit a line production station of a pipeline critical for Russian army supplies, the military said. It was not clear if the recent attacks had an immediate effect on Russian oil exports. Ukraine has in recent weeks renewed its campaign of long-range drone attacks on Russian oil production sites, systematically targeting key facilities to try to reduce Moscow's export revenues and frontline supplies.
