Russia¡¯s Federal Security Service said on Thursday it had foiled several plots by Ukrainian intelligence services to kill high-ranking Russian officers and their families in Moscow using bombs disguised as power banks or document folders.

On Dec. 17, Ukraine¡¯s SBU intelligence service killed Lieutenant General Kirillov, chief of Russia¡¯s Nuclear, Biological and Chemical Protection Troops, in Moscow outside his apartment building by detonating a bomb attached to an electric scooter.

An SBU source confirmed that the Ukrainian intelligence agency had been behind the hit. Russia said the killing was a terrorist attack by Ukraine, with which it has been at war since February 2022, and vowed revenge.
