A number of Formula 1 personnel are being treated by medical staff at the Circuit de Catalunya for burns and smoke inhalation following a major fire in the Williams garage after the Spanish Grand Prix.
Shortly after a team photo was taken to celebrate Pastor Maldonado's victory, around 90 minutes after the end of the race, it is believed that fuel exploded while it was being prepared for transportation as part of the post-race procedure.
The explosion filled the garage with black smoke, which poured into the pits and paddock, and personnel from a number of teams as well as track officials moved quickly to put the blaze out.
A number of team members were caught up in the incident, with those suffering from burns and smoke inhalation being taken to the medical centre.
While there has been no official confirmation of the number of F1 personnel involved in the incident or the extent of their injuries, Williams, Force India and Caterham have confirmed that their staff members are being treated.
Williams has said that four of its crew are being looked at in the medical centre, although the extent of the injuries is unknown.
Force India has confirmed that one of its team members was being treated for smoke inhalation, while Caterham has issued a statement confirming that four of its crew are being attended to too.
"Caterham F1 Team was involved in a fire that started in the Williams F1 Team's garage after the end of the Spanish Grand Prix," it said in a statement.
"All the team's employees have been accounted for and four people have been taken to the circuit medical centre for examination; one with a minor hand injury and three with respiratory issues.
"A further statement will be issued when more details about the incident are confirmed."
