Ukraine just launched a series of drone strikes on Russia's oil refineries, knocking out about 30% of their processing power.
Nine big refineries, including ones in Ryazan, Yaroslavl, and the Volga region, were hit hard, disrupting operations and making Russia's fuel shortages even worse.
Sergei Lavrov says Ukraine ignored Trump
These attacks could have cut crude processing by as much as 200,000 tons per day, a huge blow that some are calling a disaster for Russia's fuel supply chain.
This could mess with both their energy exports and what's available at home.
While Russia's Foreign Minister Sergei Lavrov accused Ukraine of ignoring Trump's calls to halt strikes on Russian energy infrastructure, Ukraine's President Zelenskyy says these strikes are necessary payback for ongoing Russian aggression.
All this comes just after US President Trump suggested a ceasefire to stop attacks on energy sites, so tensions are definitely running high.
