A Russian general was killed by a car bomb in southern Moscow on Monday, Russian investigators said, adding that they suspected Ukrainian special services could have been behind the attack.

The bomb exploded under the Kia Sorento driven by Lieutenant General Fanil Sarvarov, head of the Russian General Staff’s army operational training directorate, as he left a parking space at 06:55 Moscow time.

Russia’s State Investigative Committee said that Sarvarov died as a result of his injuries.

The investigators published a video showing the wrecked car, with blood visible on the driver’s seat.

The committee said that one of the versions being investigated is that the bomb was planted by Ukrainian special services. There was no immediate comment from Ukraine.
