“There are still smouldering fires so the building is difficult to access,” Andreas Leandersson, emergency services spokesman at the southern Älvsborg rescue service, told Swedish newspaper, Aftonbladet.
Göran Carlbom, duty officer of the Swedish police, Western Region, told TT that it is too early to say if the fire was started deliberately.
“At present there are no such suspicions. We must talk to the patrol and rescue services first,” Carlbom said
The extent of the damage that the building sustained was difficult to determine on Sunday morning but police confirmed that arson is one avenue of enquiry.
“We have a patrol on the site and will start the investigation as soon as possible,” a police spokesman told TT.
“It is no longer possible to use the site. All activities have been cancelled until further notice,” the mosque’s administration said on Facebook.
