Escorted by police, gay rights activists march holding a banner calling for same-sex marriages in Zagreb on May 27, 2013. Some 400 people took part Monday in the first ever same-sex marriage march in staunchly Catholic and largely conservative Croatia, set to join the European Union on July 1. The participants marched through Zagreb to the main government offices where they put out a giant rainbow flag and read out their demands. AFP PHOTO / STR
