Formula 1 teams and drivers have reacted to the "heartbreaking" news that a volunteer marshal was killed in a British club racing meeting at Brands Hatch on Saturday.
The incident occurred during a British Automobile Racing Club championship event after a car spun into the barriers and made contact with a marshal's post.
An air ambulance was in attendance with the rest of the running cancelled.
The condition of the driver remains unknown.
In a statement, the BARC said: "The British Automobile Racing Club is saddened to confirm that as a result of an accident that occurred during a race meeting at Brands Hatch circuit today (Saturday 31 July), a volunteer marshal tragically lost their life. The rest of the day’s racing activity was cancelled.
"As with any major incident, the BARC is now working with the national governing body, Motorsport UK, and the local police.
"On behalf of everyone connected with the BARC, we are devastated by loss of one of the amazing volunteer marshal community who do so much to enable the sport to take place. Our thoughts and best wishes are with the family and friends of all those involved.
"It is anticipated that the event will resume on Sunday."

F1 and motorsport as a whole could not operate without the volunteer marshals, affectionately referred to as the 'Orange Army'.

A growing number of drivers and teams have also taken to social media to pay tributes.
