Large increase in gang violence yes. But this is a pretty strong and specific claim, I live in Sweden and have not seen this in the news. Some of the gangs part of the gangswars are MC related clubs like Bandidos which seem to be mostly ethnically Swedes, and they've been an issue for decades.

Arguably part of the problem is our emulation of US war on drugs, it failed there and its obviously failing here and allows gangs to have large income. Together with bad integration and prospects for children of immigrants/refugees allows gangs to influence and exploit them to do crime and attacks for them.
