Eight people have died after an out-of-control monster truck ploughed into a crowd of spectators at a Mexico air show.
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.
Footage shows the truck bouncing around after the jump and then driving into spectators standing about 10 metres (32ft) away.
At least one child is among the dead and 80 people were hurt, with 46 still hospitalised on Sunday morning, said Mr Gonzalez.
It is thought the number of people killed could rise and local health authorities have also put out an urgent call for blood donors.
Prosecutors are looking into the possibility of a mechanical failure that left the driver unable to release the accelerator pedal.
Some witnesses also said the driver appeared to have hit his head on the inside of the truck during the jump, causing his helmet to come off.
The air show - at the El Rejon park near Chihuahua - is an annual festival where planes, motorbikes and monster trucks perform stunts.
The remainder of the three-day event was cancelled after the crash.
