Russia Arrests Suspect in High-Profile General’s Assassination

Russia’s Federal Security Service (FSB) detained Wednesday a suspect in the assassination of Lt. Gen. Igor Kirillov, who was killed by a bomb hidden in a scooter outside his Moscow apartment.

The suspect, identified as an Uzbek citizen born in 1995, allegedly acted under orders from Ukrainian intelligence, according to the FSB.

Ukraine’s Security Service (SBU) has taken credit for the attack, calling Kirillov a “legitimate target” due to his role in directing the use of banned chemical weapons—an allegation Russia denies.

Kirillov, the chief of Russia’s nuclear, biological, and chemical protection forces since 2017, was a controversial figure, often accusing Ukraine of using toxic agents in combat.
