Clashes have taken place for a fourth day in several Swedish cities, sparked against Quran desecration by a far-right, anti-immigrant group.
Local media said three people were injured in the eastern city of Norrköping on Sunday when police fired warning shots at rioters.
Several vehicles were set on fire and at least 17 people were arrested.
On Saturday, vehicles including a bus were set on fire in the southern city of Malmo during a far-right rally.
Earlier, the governments of Iran and Iraq summoned Swedish envoys to protest about the burning.
Danish-Swedish extremist Rasmus Paludan, who leads the Stram Kurs, or Hard Line, movement said he had burned Islam’s most sacred text and would repeat the action.
