UNNAMED GROUPS ACTIVE

"Certain population groups" are making work difficult for Sweden's firefighters:

Firefighters in Malmö in southern Sweden are demanding police escorts on calls. The firefighters have had enough of threats and violence in some of the city's rougher areas.

After being attacked by stones on a recent call, they are threatening not to take calls to Rosengård without a police escort. They are also demanding shatterproof windows and surveillance cameras on their vehicles.

I'm guessing it's maybe Lutherans.
