The shooting took place on an island (Utøya) some distance from Oslo. The youth organization of the social democratic party (the major party in government) has a camp there every summer.

One person shooting wildly - looks more like a "school shooting", but according to rumors the perpetratot wore a police like uniform, and got access to the island, claiming it was a routine operation connected to the bombing.

IF there is a connection, it sounds like this is not an al quaida operation or similar, I can't see why they would, in addition to bombs in Oslo, send one person to shoot wildly at a summer camp.

BTW, I live in Bergen 500 km from Oslo.
