At least 13 people including three children were killed when a Sukhoi Su-34 fighter jet crashed into the courtyard of a nine-storey apartment building and exploded in a fireball in southern Russia just across the Sea of Azov from Ukraine.
The supersonic jet, which the defence ministry said was on a training flight, was seen on video footage speeding across the horizon on Monday with a fire in one engine before a blast and a fireball engulfed the building in the city of Yeysk.
