COPENHAGEN, Denmark — Police have arrested 50 people after mobs of youths torched cars and lobbed rocks at officers and firefighters in a sixth night of violence in Danish cities.
A police spokesman said youths were arrested overnight in Copenhagen, Aarhus, Ringsted and other towns.
It remained unclear exactly what triggered the unrest.
Some say immigrant youths were protesting alleged police harassment, and that the reprinting of a controversial cartoon lampooning the Prophet Muhammad aggravated the situation.
On Wednesday, more than a dozen Danish newspapers reprinted the Muhammad cartoon that sparked massive protests in Muslim countries two years ago.
They called it a gesture of solidarity after police revealed an alleged plot to kill the cartoonist.
The republication sparked more protests. In Pakistan, hundreds of protesters set fire Friday to Danish flags and demanded the Danish ambassador's expulsion.
