South Korea's gender equality and family minister has raised the issue of women used as sex slaves by the wartime Japanese military at the human rights panel of the U.N. General Assembly.

Although Cho Yoon-sun did not specifically name Japan, she called Friday on "the responsible government" to apologize and take responsible measures in her speech at the assembly's Third Committee, which oversees social and humanitarian affairs.

With the advancement of women on the committee's agenda, Cho devoted a substantial portion of her address to the issue of the "comfort women," as Japan euphemistically refers to its wartime sex slaves.
