Several clips have emerged on social media showing an explosion and fire at a munitions factory in the Russian town of Kopeisk, around 1,600 km (1,000 miles) from the Ukrainian border.

Russian state news agency Izvestia has reported two explosions at an “enterprise” in the city last night and that 12 people were killed. As yet the cause of the blast is unconfirmed.

The footage we’ve seen indicates the explosions occurred at the munitions plant, which is located near to the city of Chelyabinsk in the Urals region.

The clip in question is filmed from a moving car driving past the military facility. We confirmed the location by matching street furniture and a building visible on Google Street View.

We have also verified footage from a CCTV camera positioned around 3km (two miles) away from the site which shows one explosion.

The footage is marked with a timecode saying it was recorded at 23:44 local time (19:44 BST), which fairly closely coincides with initial reports about the explosion.
