MEXICO CITY, Oct. 6 (Xinhua) -- At least 13 people were killed and 70 others injured when a modified van crashed into spectators at an air show in northern Mexico's Chihuahua state, local media reported Sunday.
The tragedy occurred Saturday afternoon in the state's capital Chihuahua city, when the driver of the monster truck lost control of the vehicle and careened into the crowd at the Extreme Aeroshow.
Of the 13 victims, nine of them were killed on the spot, while the other four died later in nearby hospitals, the report said.
Authorities arrested the driver and are still investigating the cause. A spokesman for the State Attorney General said mechanical failure may cause the accident as the vehicle's accelerator was stuck.
Witnesses said the driver lost consciousness to bang his head against the canopy of the vehicle after performing a jump on a pile of junk cars.
Chihuahua State Governor Cesar Duarte said on his twitter account that the accident "has left us shocked," adding that "the state government will offer all necessary support to the municipality to overcome this terrible tragedy."
The Extreme Aeroshow was canceled immediately after the accident during the second day of the three-day show in a park on the outskirts of Chihuahua. It was the third annual airshow, which includes airplane stunts, skydiving and motorcycle acrobatics among other daredevil acts.
