Ukraine has destroyed a supersonic Russian jet in a drone strike, according to reports from the BBC and Ukrainian media.
The reports were based on images posted on social media which appear to show the long-range bomber, the Tupolev Tu-22, on fire. The images were analysed by the BBC, but have not been independently verified by the Guardian.
The burning plane appeared to be located south of St Petersburg, the BBC reported, using visual clues and historical satellite images of the airbase.
