(AP) An official says an out-of-control monster truck has shot into a crowd of spectators at a Mexican air show, killing six and hurting dozens.
Carlos Gonzalez, spokesman for the Chihuahua state prosecutors' office, said the driver appeared to have lost control of the truck after leaping an obstacle during a demonstration at the "Extreme Aeroshow" on Saturday.
He said the accident killed a child and five adults and seriously hurt 40 people.
Gonzalez said prosecutors were looking into the possibility of a mechanical failure that left the driver unable to release the gas pedal.
The air show was canceled after the accident.
