Russian President Vladimir Putin has described fuel shortages across Russia as "not critical", as his military conducted an 11-hour barrage on Kyiv that killed at least 30 people.
The overnight attack into Thursday morning was one of the deadliest strikes on the Ukrainian capital since Russia's full-scale invasion began more than four years ago.
Ukraine has launched more than 50 attacks on Russian oil refineries and energy sites since March, removing approximately one-third of the country's processing capability, according to Chris Weafer of consultancy Macro-Advisory. Daily petrol output has fallen by roughly 17% to 850,000 barrels.
Rationing has been imposed in many Russian regions, with motorists waiting hours to refuel. Crimea has faced the worst shortages, with sales to individuals periodically stopped altogether. Moscow authorised the manufacture of inferior petrol with elevated sulphur levels through year's end.
At a government meeting last weekend, Putin acknowledged a "difficult period" and committed to speeding up facility repairs and exploring petrol imports. He characterised Ukraine's infrastructure attacks as an attempt to distract from Ukrainian battlefield setbacks.
Putin rejected a ceasefire proposal from Kyiv and Western allies, saying it would only allow Ukrainian forces time to rest and regroup. Any halt to fighting would require Ukraine to withdraw from the parts of Donetsk region it still holds, he said.
A final peace agreement must include Ukraine abandoning its NATO membership bid, reducing its military, and protecting Russian language and culture, Putin said.
