PST considers the shooting in Oslo as an extreme Islamist terrorist act.
This is what PST chief Roger Berg says during a press conference in Nydalen at 14.00 today according to NRK.
There has been a terrorist attack, and there is an unresolved terrorist situation. Therefore, the level is set up, says Berg.
The threat level thus goes up from level 3 to level 5, which is the highest level.
Oslo Pride has canceled the Pride parade today after the terror attack in the early hours of Saturday out side LGBTQ gay pub called London Pub, after advice from the Norwegian police.
