Three teenagers have been charged following a violent attack on a gay couple at Tjuvholmen in Oslo last August.

The victims, both in their 20s, suffered injuries, with one man being stabbed and the other assaulted.

Prosecutors have charged a 17-year-old with attempted murder, another 17-year-old with aggravated assault, and a 15-year-old with both aggravated assault and hate speech.

Authorities believe the attack was motivated by the victims' sexual orientation.

The case highlights ongoing concerns about hate crimes in Norway.
