National flags are set at half mast at the Nordic embassies to Germany in Berlin, July 23, 2011. A suspected right-wing Christian gunman in police uniform killed at least 84 people in a ferocious attack on a youth summer camp of Norway’s ruling Labour party, hours after a bomb killed seven in Oslo. The flags represent L-R: Denmark, Finland, Iceland, Norway and Sweden. REUTERS/Tobias Schwarz (GERMANY – Tags: CIVIL UNREST POLITICS CRIME LAW)
