Police said at least 85 people were killed in Friday's shooting attack on a youth camp near Oslo, while the search for victims continued, dpa reported.
A 32-year-old Norwegian man, who has not been officially identified, was earlier Saturday charged with the shootings, as well as for a bomb explosion in central Oslo that claimed seven lives.
The number of fatalities could still rise as police were searching the waters off Utoya island where the camp was organized by the youth league of the Labour Party.
