KYIV, May 20 – Ukrainian forces reportedly conducted successful drone strikes against Russian military infrastructure and oil refineries in occupied Crimea, Krasnodar Krai, and Leningrad region on the night of May 18 to May 19, according to the American Institute for the Study of War (ISW).

"Ukrainian forces launched 12 ATACMS against Sevastopol Bay — nine of which Russian forces shot down near Sevastopol and Belbek airfield, and three of which struck a vessel in Sevastopol port. Footage published on May 19 purportedly shows Russian forces attempting to repel Ukrainian drones over the port in Novorossiysk, Krasnodar Krai. Krasnodar Krai Governor Venyamin Kondratyev claimed that Russian air defense suppressed over 10 drones near Novorossiysk and that falling debris caused fires," the report reads.
