Local media footage showed smoke and flames billowing from the windows before firefighters put the blaze out.
The incident comes amid a fierce debate in Sweden over immigration policies. The far right wants to cut the number of asylum seekers allowed into Sweden by 90%, while mainstream parties are intent on
preserving the country’s liberal policy.
“A witness saw somebody throw an object through the window of the building, which serves as a mosque, after which a violent fire began,” Lars Franzell who is the Police spokesman told reporters.
Franzell said five people were taken to hospital for treatment of injuries ranging from smoke inhalation to lacerations.
Police are treating the incident as arson but no arrests have been made so far, Mr Franzell added. Eskilstuna, which has a large immigrant
population, was the scene of clashes involving neo-Nazi groups opposed to Sweden’s immigration policy earlier this year. On the 3rd of December, the Sweden Democrats – a populist party with a strongly anti-immigration
agenda – brought down the minority governing coalition after it had been in power for just two-and-a-half months, by refusing to support its budget plans.
