Ukraine launched a wave of overnight drone attacks deep inside Russia just as world leaders gathered in Davos and U.S. envoys prepared to meet President Vladimir Putin in Moscow. Strikes hit an oil terminal and the Afipsky oil refinery in southern Russia’s Krasnodar Krai, killing at least three people, injuring others, and setting multiple fuel tanks ablaze, according to local authorities and Ukrainian media. Additional attacks struck Russia’s Republic of Adygea, damaging residential buildings. This came as President Volodymyr Zelensky skipped Davos, saying he would attend only if new U.S. air-defence and energy aid were secured, while Trump’s envoys Steve Witkoff and Jared Kushner headed to Moscow for talks on a peace deal.
