Deadly Mexico 'monster truck' crash at air show
A number of people have been killed and dozens injured at an air show in Mexico, after a modified pick-up known as a monster truck crashed into spectators.
The monster truck - with tyres said to be 1.5 metres (nearly 5ft) high - ploughed into a stand in the northern city of Chihuahua.
The BBC's Will Grant said the driver appeared to lose control of the vehicle before it hit the spectators.
