Lt. Gen. Igor Kirillov, the commander of Russia’s chemical, biological and radiation defense forces, and his assistant were killed during an explosion in Moscow on Tuesday, just a day after he was charged criminally by Ukraine's Security Services.
Russia's Investigative Committee said the explosive device was placed in a scooter near a residential apartment block on Ryazansky Avenue and triggered remotely, according to The Associated Press.
The bomb had the power of roughly 300 grams of TNT, according to Russian state news agency Tass.
Reuters reported that Ukraine's Security Services, also known as the SBU, claimed responsibility for the hit on Kirillov. Fox News Digital has reached out to the intelligence agency for confirmation.
