Two people were killed and seven others were injured in a head-on collision between a Dakar Rally support vehicle and a taxi near Peru's border with Chile.
The incident happened at 9:30pm local time on Wednesday, 10km from the frontier.
A statement on the dakar.com race website said one taxi hit the support vehicle head-on and a second cab overturned as its driver tried to avoid the collision.
Two people in the first taxi, including the driver, were killed and seven people, four of them Peruvian, were injured. Three of the injured were in the rally support vehicle. All were taken to hospital for treatment.
The collision came after the fifth stage of the race from Arequipa in Peru to Arica in Chile. The 8400km event is being staged in South America with 459 vehicles.
