They are the most vociferous of the protests taking place across the US against a grand jury decision not to indict the killer of black teenager Michael Brown.
Prosecutor Bob McCulloch issued a statement saying police officer Darren Wilson had been found to have acted within the law and in keeping with his training.

Questions have been raised as to why officials waited until 8pm, when night had fallen, for the verdict on Wilson's fate to be announced.
