A senior Russian general, Lt. Gen. Igor Kirillov, was killed in a bomb blast in Moscow, reportedly orchestrated by Ukraine's Security Service. Kirillov was head of Russia's radiation, chemical, and biological protection troops. He was targeted with a scooter-based explosive, killing both him and an aide. The SBU accused him of war crimes, alleging he authorized over 4,800 uses of banned chemical weapons against Ukrainian forces. Video footage of the attack was shared with the media, and SBU sources labeled the operation as "retribution" for war crimes.
