German Chancellor Angela Merkel prepares the wreath after a wreath-laying ceremony at the wall of the Concentration Camp Memorial in Dachau, southern Germany on August 20, 2013. More than 200,000 Jews, gays, Roma, political opponents, the disabled and prisoners of war were imprisoned in Dachau during World War II. Merkel became the first German Chancellor to visit the camp but critics slammed her decision to include the stop on an election campaign swing. TOPSHOTS/AFP PHOTO / GUENTER SCHIFFMANN
