Stockholm police called in reinforcements from across Sweden to
quell a possible sixth straight night of riots in the country's
capital.  The nightly unrest led Britain's Foreign Office and
the United States embassy on Friday to warn their nationals
against travelling to the affected areas.  "We will be getting
reinforcements from Gothenburg and Malmoe tonight," police
spokesman Kjell Lindgren said, naming the country's next two
largest cities.  Parents and volunteer organisations who have
patrolled the streets in recent nights have helped decrease the
intensity of the unrest, Lindgren said.  No information about
the specific number of police due to arrive was revealed.
Minister for Integration Erik Ullenhag said the violence was
being committed by a small group of people, many of whom were
already known to the police and did not live in the area were
they were causing trouble.  "What we are seeing are extreme,
unusual events. But we need to be absolutely clear about one
thing: we can never accept violence,"
