Ukraine claims strike hits Russia’s large oil refinery and pumping station
Ukraine says its forces struck Russia's Lukoil-Nizhegorodnefteorgsintez refinery in Kstovo and the nearby Yaroslavl-3 oil pumping station on May 18–19, potentially shrinking Moscow's fuel capacity; the refinery is among Russia's largest (about 17 million tons annually) and provides gasoline, diesel, and aviation fuel for the military, though the full extent of damage remains unclear, while Russia reported drone incidents in Yaroslavl and near Moscow with no casualties.
