SEOUL, Aug. 15 (Yonhap) -- Hundreds of South Koreans joined a weekly rally in Seoul against Japan's wartime sex slavery on Wednesday as patriotism soared across the country on the 73rd anniversary of its liberation from Japan's colonial rule.

Despite the sweltering weather, about 700 activists, citizens and Korean women who were forced to serve at Japan's army brothels during World War II gathered in front of the former building of the Japanese Embassy.

"I will live to the age of 200 to resolve this historical issue with you. There should be never such atrocities," Lee Yong-su, a former sex slave, told participants at the rally.

Protesters chanted slogans, such as "Apologize to the victims of the sex slavery!" and "Compensate the victims legally!"
