Sex slave issue: South Korean leader Moon criticizes Japan

South Korea's president has criticized Japan's insistence that the issue of women forced to provide sex for Japanese troops in World War II has been settled.

President Moon Jae-in said Thursday that Japan "should not say the matter is closed." He added that "a crime against humanity committed in time of war cannot be closed with just a word."

So-called comfort women provided sex for Japan's military in conditions that many experts say were sexual slavery. Many of the women were from Korea, then a colony of Japan, who were taken to front-line brothels.

The previous South Korean government signed an accord with Japan in late 2015 to settle the issue, which has bedeviled bilateral relations. The Japanese government said it lodged a "strong protest" over Moon's remarks.
