The incident occurred at the Ilsky refinery near the Black Sea port of Novorossiysk in the Krasnodar region. Meanwhile, the Institute for the Study of War says that the Kremlin drone attack was "likely staged" by Russia, and that Moscow may use the strike to limit or cancel 9 May Victory Day events.
