A unidentified survivor from the shooting at an island youth retreat reacts as she embraces a man outside a hotel where survivors were being reunited with their families in Sundvolden, Norway, Saturday, July 23, 2011. A Norwegian dressed as a police officer gunned down at least 84 people at an island youth retreat before being arrested, police said Saturday. Investigators are still searching the surrounding waters, where people fled the attack, which followed an explosion in nearby Oslo that killed seven. The mass shootings are among the worst in history. With the blast outside the prime minister's office, they formed the deadliest day of terror in Western Europe since the 2004 Madrid train bombings killed 191. (AP Photo/Matt Dunham)
