Ukraine hits two Russian oil refineries overnight

Ukraine hit two Russian oil refineries in the regions of Krasnodar and Yaroslavl overnight, President Volodymyr Zelenskiy said on Sunday, as Kyiv ramps up pressure on Russia's fuel supply with its drone fleet.

Kyiv's increasingly frequent drone attacks have caused acute fuel shortages in parts of Russia, one of the world's biggest oil producers, with queues and rationing seen at petrol stations.

"We continue our operations that weaken Russia's ability to wage this war," Zelenskiy wrote on social media, adding that the refineries were about 300 km and 700 km from Ukrainian territory.

In a statement on Telegram on Sunday, Krasnodar region governor Veniamin Kondratiev said that a fire had broken out at the refinery in Slavyansk-na-Kubani, with one person killed and another injured in a nearby village.

Unverified footage on social media showed a large fire at the refinery.

Slavyansk refinery is a private plant with a capacity of about 100,000 barrels per day. It supplies fuel for domestic use and export.

In Yaroslavl region, east of Moscow, the governor said the region had come under drone attack and that temporary limits had been placed on movement on some road routes to the Russian capital.
