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

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.

The blast took place close to the location where a senior Russian general was killed in a car bombing in the capital on Monday.

Lt Gen Fanil Sarvarov died after an explosive device - which had been planted under a car - was detonated.
