This happened on October 25, 2019 in Norway. According to the backinfo I got, a 16 year old Afghani refugee stabbed 18 year old Norwegian guy multiple times in the back.
The Norwegian was critically injured, but survived. The video shows mostly the aftermath of the stabbing.
The incident happened in Haugesund, Norway. The 16 year old refugee was reportedly arrested and charged with attempted murder. Many thanks to @mineprairiedog for the update.
Props to Best Gore member @assviolator for the video:
