Armen Sarkisyan, a criminal authority from the era of Ukrainian pro-Russian ex-president Viktor Yanukovych, was blown up in Moscow. Meanwhile, Ukrainian drones attacked the Volgograd oil refinery and Astrakhan gas processing plant in Russia.

Ukraine is believed to have launched a new drone attack on Russia, targeting a major oil depot in the southern Krasnodar region. Kyiv has stepped up its aerial attacks across Russian regions over the winter, as it seeks to disrupt fuel and ammunition supply lines to Putin's army in Ukraine.
