Ukrainian drone strike forces Russian Syzran refinery offline

A Ukrainian drone strike on May 21 damaged the main crude distillation unit at Russia's Syzran oil refinery, forcing the facility to halt operations. Repairs to the CDU-6 unit, which processes most of the refinery's capacity, are expected to take over a month, according to Reuters.

The Syzran refinery is one of several Russian oil processing plants targeted by Ukrainian strikes as part of broader efforts to disrupt Russia's energy infrastructure and war economy. The damage to the CDU-6 unit represents a significant blow to Russian crude oil processing capacity during the ongoing conflict. Such strikes aim to constrain Russia's ability to generate revenue and maintain fuel supplies for military operations.
