Brown Ferguson: Jury decision not to charge sparks riot

A US grand jury has decided not to charge a police officer over the fatal shooting of unarmed black teenager Michael Brown in Ferguson, Missouri.

State prosecutor Robert McCulloch said the jury had exhaustively examined the evidence but Mr Brown's family said they were "profoundly disappointed".

News of the ruling sparked the worst night of rioting yet in Ferguson.

Shots were fired and cars and buildings set alight as police fired tear gas to break up the crow of protesters.
