Igor Kirillov, chief of Russia’s Radiation, Chemical and Biological Protection troops, was killed in an explosion in Moscow, believed to be orchestrated by Ukraine’s SBU as part of a special operation against him. Known for overseeing chemical weapon use in Ukraine, Kirillov was seen in Russia as a patriot but faced significant accusations from the West. His controversial briefings had made him a prominent figure in Kremlin disinformation efforts. The incident raises further tensions amid ongoing allegations of chemical weapon deployments in Ukraine.
