At least 80 people are dead as a result of a rampage Friday on a Norwegian island, police said, an attack that came shortly after an explosion killed seven others in the Scandinavian nation's capital.

Police have detained a 32-year-old Norwegian man who they suspect opened fire on scores at the ruling Labour Party's youth camp on Utoya Island, about 20 miles from Oslo. Police spokesman Are Frykholm, who told CNN early Saturday about the death toll spike, said authorities are investigating further, based on information from the man.


That attack and the massive explosion in the heart of Oslo are definitely linked, police said.
Seven were killed in the attack in the Norwegian capital, officials said. In all, 90 people were hospitalized as a result of the Oslo blast, said Erik Hansen, a spokesman for Oslo Mayor Fabian Stang.
