Three people - including two police officers - have been killed in an explosion in Moscow, Russian authorities have said, BBC reported. 

Two traffic police officers saw a "suspicious individual" near a police car on the city's Yeletskaya Street, and when they approached the suspect to detain him, an explosive device was detonated, Russia's Investigative Committee has said. 

The two police officers died from their injuries, along with another individual who was standing nearby, according to BBC.
