Norway mourns massacre victims

A Norwegian flag stands amid flowers July 24, 2011 in Oslo, as Norwegians pay tribute to the victims of a bomb explosion which ripped through government buildings and the shooting spree at the youth camp of the Norwegian Labour Party, two days ago. The suspect in Norway's twin attacks that killed dozens says he acted alone, police said, in a "cruel" but "necessary" slaughter planned over many months. As Norway's king and prime minister joined mourners in the cathedral, police said they are still trying to establish whether there was "one or several" shooters in the attack on Utoeya island, northwest of Oslo.

Dozens of young people were killed or wounded in Friday's shooting spree on the island just outside the capital - and the figure could rise, a senior police officer said.
