Norwegian Prime Minister Jens Stoltenberg, back to camera third left, comforts teenagers who were attending a Labour Party youth wing summer camp on the Utoya island at the Sunvold Hotel, Sundvollen, Norway Saturday July 23, 2011. A Norwegian gunman disguised as a police officer beckoned his victims closer before shooting them one by one, claiming at least 84 lives, in a horrific killing spree on an idyllic island teeming with youths that has left this peaceful Nordic nation in mourning. The island tragedy Friday unfolded hours after a massive explosion ripped through a high-rise building housing the prime minister's office, killing seven people.
