Lieutenant General Igor Kirillov, head of Russia’s Nuclear, Biological, and Chemical Protection Troops, was killed outside an apartment building on Ryazansky Prospekt in Moscow.
The blast also claimed the life of his assistant.
“Igor Kirillov, the head of the radiation, chemical and biological protection forces of the armed forces of the Russian Federation, and his assistant were killed,” the Investigative Committee said in a statement.
