French driver Anthoine Hubert has been killed in a Formula Two accident at the Belgian Grand Prix.
The 22-year-old died following a 160mph collision at the high-speed Spa-Francorchamps track.
Hubert raced for the British-owned Arden team, founded and run by Garry Horner, the father of Red Bull team boss Christian Horner.
A number of drivers were involved in the second-lap accident on the exit of the fearsome Eau Rouge corner.
The official TV feed swiftly cut away from the scene and there were no replays of the accident.
But footage of the incident which later emerged on social media appeared to show Hubert slamming into the barriers on the far side of the circuit before sliding across the track.
Ecuadorian-American Juan Manuel Correa then crashed head on into Hubert, whose car appeared to break in two.
Correa was taken to Liege Hospital and is reported to be in a stable condition.
The Formula Two race, which acts as the feeder championship to Formula One, followed the conclusion of qualifying for the F1 grand prix which saw Ferrari driver Charles Leclerc secure pole position ahead of Sebastian Vettel and Lewis Hamilton.
A statement released by the sport's governing body, the FIA, read: "The Federation Internationale de l'Automobile (FIA) regrets to advise that a serious incident involving cars #12, #19 and #20 occurred at 17:07 on 31/08/19 as a part of the FIA Formula 2 Sprint Race at Spa-Francorchamps, round 17 of the season.
