Ukraine's military reported striking a Russian military plant that produces drone components deep inside Russia, along with attacks on oil infrastructure. The strikes targeted an oil refinery and a "shadow fleet" oil tanker in the Black Sea. Ukraine stated that its missiles successfully hit the military manufacturing facility, which supplies key components for Russian drones used in the conflict.
The attacks caused fires at multiple oil facilities in Russia and Crimea. Russia characterized the strike on St. Petersburg as unprecedented in scale.
