Police say youths in southern Sweden set fires and hurled rocks at police in unrest sparked by the closure of an Islamic cultural center.
Police spokesman Charley Nilsson says no injuries have been reported, but several trailers, containers, garbage bins and at least two cars were set ablaze in Malmo, Sweden's third largest city. One person was arrested.
The violence has escalated every night since Monday, when police removed squatters protesting the eviction of an Islamic group from their basement premises in an immigrant neighborhood. Nilsson says leftist activists from other parts of the city have joined the protests.
Police say there are no immediate signs of a link to the violent protests in Greece.
