Remarkable piece of detective work if they're right. "The world's first ever footage of Korean sex slaves used by Japanese soldiers during WWII has emerged. Grainy black and white footage from 1944 shows seven bare-footed women outside a brick house said to be a military-run brothel in occupied China as it was liberated from the Japanese by Allied forces. One woman in a dirty blouse is seen talking to a Chinese officer, others stare nervously at the ground and one, who appears to be pregnant, gently touches her bump. Until now, photographs and accounts from survivors - labelled 'comfort women' by Japanese forces - have been the only records of Korean sex slavery. But after a two year trawl through US archives, researchers uncovered footage which appears to show sex slaves at Songshan, Yunnan Province, as US-China Allied Forces reclaimed Songsan from the Japanese. A team from Seoul University and Seoul Government matched the footage outside the building to pictures and identified the women by their clothes and facial appearance."
