The Russian military accused Kyiv of using US and British-supplied missiles for one of the strikes and promised it would "not go unanswered".

The barrage forced schools in the Saratov region to close, while at least nine airports in central and western Russia temporarily halted traffic, according to Russian officials. Moscow and Kyiv have upped strikes on each other ahead of US President-elect Donald Trump's inauguration next week, as both sides seek to gain the upper hand in potential negotiations aimed at settling the war.
