The alarm came in around 01.30.
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.
The rescue service will stay until the morning for extinguishing.
The building will be completely destroyed. It will not be possible to use it for anything, says Michael Hesselgård.
When the rescue service leaves, the site will be blocked off and investigated by the police. The incident is being investigated as a suspected arson.
The classification is set because we do not know why it has started burning, says the police's press spokesperson Patric Fors.
