Ukraine launched a massive wave of drone strikes overnight that forced the Crimean Bridge to close and grounded flights from Moscow. Russian Defence Minister Sergei Shoigu ordered the Black Sea navy to strengthen the protection of its facilities and conduct regular drills. Shoigu “ordered the installation of additional firepower, large-calibre machine gun systems” on its Black Sea warships “to defeat enemy drones”. The Siberian Battalion, an anti-Kremlin Russian group, claimed to have entered the settlement of “Gorkovsky” in Russia’s Belgorod Oblast. Russia downed 36 Ukrainian drones overnight, including five in the Moscow region, the Russian defence ministry reported on March 17.
