A Tesla electric car caught fire after crashing into a tow truck on a Moscow motorway late on Saturday.

Footage of the incident on state TV channel Rossia 24 showed the car by the side of the road engulfed in flames and thick black smoke. Two small explosions occurred within a few seconds of each other.

It was not possible to tell which Tesla model the car was and only the metal frame remained after the fire.

Tesla Inc stood by safety claims for its Model 3 earlier this week in the face of regulatory scrutiny, while documents showed the top U.S. automotive safety watchdog issued at least five subpoenas since last year seeking information about crashes involving the company's vehicles.

The state-run RIA news agency website posted a video showing the car driving in the left-hand lane of Moscow's ring road, known as the MKAD, before crashing into a tow truck parked by a safety fence that separates the carriageway from oncoming traffic.
