LONDON — A senior Russian general was killed in a bomb blast in a residential neighborhood in Moscow, Russian media reported early Tuesday. Lt. Gen. Igor Kirillov was killed by an explosive device that appears to have been hidden in a parked scooter and set off by remote control, Russian state-affiliated media TASS reported. The explosion also killed an aide accompanying him. Kirillov was the head of Russia’s radiation, chemical and biological protection troops, TASS noted.
