We do not know how the fire started, but it has burned heavily in the building. It was previously a church that is now used as a mosque, says Michael Hesselgård at the rescue service.
No person is reported to have been injured. The rescue service will stay until morning for extinguishing.
The building will be completely destroyed. It will not be possible to use it for anything, says Michael Hesselgård.
The alarm came in around 01.30.
