What happened

Ukrainian drones struck Rosneft's Ryazan refinery and started a fire. Russian officials confirmed the attack, while U.S. government and industry reporting said two primary processing units were damaged and taken offline, sharply reducing throughput at one of Russia's largest refineries. Regional authorities reported two people injured.
