About five Muslims have been injured in the Swedish town of Eskilstuna on Thursday, December 25 as an arsonist set fire to a Mosque.
According to reports, about 15-20 Muslims were attending midday prayers in the mosque, located in the ground floor of a residential building, when the fire broke out on Christmas Day.
The local media coverage 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," police spokesman Lars Franzell told reporters.
He 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.
