A Norwegian flag flutters aside a candle outside Oslo Cathedral among tributes for the victims of the July 22 shooting at a Norwegian Labour Youth League camp, on July 23, 2011. Police said they were questioning a Christian fundamentalist Saturday over twin attacks on a youth camp and the government headquarters that killed 91 people in Norway's deadliest post-war tragedy. As harrowing testimony emerged from the holiday island where scores of youngsters were mown down by a gunman dressed as a policeman, Norway's premier said the country would emerge stronger from the "cruel act of violence".
