Fresh clashes

Some 17 cars were reported to have been burned in Utrech overnight, but the BBC's Johnny Dymond said areas that had been at the centre of previous violence were virtually deserted.
He says there is no easy explanation for the sudden stop in the violence - it may be that the riots have run their course, or that the rioters are simply drawing breath. An organized figth?
the police is afraid of the possible spreding of the violence over the area.
