South Korean women, who were forced to serve as sex slaves for Japanese troops during World War II, hold a butterfly-shape placard reading 'officially apologize' during an anti-Japanese rally in front of the Japanese embassy in Seoul, 31 July 2007. They welcomed the passage of a resolution by the US House of Representatives calling on Japan to formally apologize to the victims and accept historical responsibility.
