Sweden experiences restless nights.
Since Thursday April 14, Norrköping and Linköping, two cities southwest of Stockholm, have been the scene of clashes every night between the police and rioters.
Twenty-six people suspected of having taken part have been arrested, Swedish police announced on Monday.
Demonstrators are protesting against a rally by the anti-immigration and anti-Islam group "Hard Line", led by Danish-Swedish Rasmus Paludan.
The far-right leader, who was sentenced in Denmark for racist insults, has been on a "tour" of Sweden in recent days, targeting neighborhoods with large Muslim populations to burn the Koran there and sparking violent counter-demonstrations on his passage.
Malmö also affected
On Sunday, many Swedes demonstrated again to protest against new announced rallies, which Mr. Paludan finally gave up.
In Norrköping, the police fired warning shots which in turn injured three people.
In Malmö, where he burned a Koran on Saturday, the night from Sunday to Monday was agitated, for the second consecutive time, with in particular a fire starting in a school.
Outrages abroad
Mr Paludan's holding of rallies where he burns the Koran has sparked protests across the Arab world.
Iraqi diplomacy, which summoned the Swedish charge d'affaires, judged that it was an act "provocative for the feelings of Muslims and offensive for what is sacred to them".
Saudi Arabia also "condemned the actions of certain extremists in Sweden and their provocations against Muslims", according to its official agency.
