Ukraine launched a large-scale drone attack on May 15, striking energy infrastructure in multiple Russian regions.
Social media reports indicate a significant fire at the Ryazan oil refinery. The facility maintains an annual production capacity of over 17 million tons.
This operation aims to disrupt fuel supplies for the Russian military and curb energy revenues. Attacks on Russian oil infrastructure reached a four-month high in April.
Oil markets are sensitive to these disruptions due to ongoing instability in the Middle East. Tensions surrounding the Strait of Hormuz further exacerbate supply concerns.
