Via the  BBC,  Twin terror attacks shock Norway

Norway has been hit by twin attacks – a massive bomb blast in the capital and a shooting attack on young people at a governing Labour Party youth camp

At least seven people were killed in the bombing, which inflicted huge damage on government buildings in Oslo city centre.   Four more died at the camp, on an island outside Oslo, local media said.  One witness later said he had seen more than 20 bodies on the island, but police have not confirmed this.   Prime Minister Jens Stoltenberg, whose Oslo offices were among those damaged by the bomb, described the situation as “very serious”.  Norwegian media reports said the shootings on the island were carried out by a man in police uniform.    Police said the suspected gunman had been arrested, and later said he was also linked with the bomb attack, reports said.

No group has said it carried out the attacks.

Hours after the bomb struck Oslo, officials said some people were still inside the damaged buildings, some of which were on fire.
