"Smoke rises from the interior of a destroyed cellar mosque as firefighters search the remains of the building after an arson attack on December 25, 2014 in Eskilstuna, central Sweden. An arsonist set fire to the mosque in central Sweden on Thursday injuring five, police said, as the country faces a deep political crisis caused by the rise of the extreme right", AFP reports.

“Somebody threw an object through a closed window and afterwards a fire started inside,” police spokesman, Lars Franzell, said on Thursday.

“There were between 15 and 20 people in the premises,” Franzell added.

The move to rebel against the government budget proposal was considered a major political breakthrough for Sweden Democrats, which became the country’s third-largest group in parliament in the September general elections. The far-right party holds strong views against immigration.
