What happened

A Ukrainian drone strike caused a fire at Rosneft's Syzran refinery. Samara regional authorities confirmed the refinery fire, and industry reporting said the plant's main crude-distillation unit was taken offline. One person was reported injured; a simultaneous attempted strike on the nearby Novokuibyshevsk refinery did not cause a fire.
