Two teenagers were killed in a crash before mass violence broke out in Cardiff last night, with cars torched and missiles hurled at officers.
Riot officers battled with swelling crowds of rioters into the early hours of Tuesday morning, with pitched battles at one point involving up to 150 members of the public.
A heartbroken mum pleaded with rioters to stop as her teenage son Kyrees Jordan Sullivan and his friend Harvey Evans lay dying.
