Adults can be seen selling noodles, potatoes and kimchi on the streets, seemingly oblivious to the starving children wandering around them, combing the ground for anything edible.

It was a scene from a video shown to journalists Friday by an associate professor at Kansai University. Lee Young Hwa, a Korean descendant who was born in Japan, said the video was shot in North Korea by a North Korean refugee who sneaked back into North Korea from China.

He said the 90-minute video, "Inside North Korea," was shot in early October by the refugee, whom he had met in China in August and handed a video camera. The footage shows black markets and starving children in two unnamed towns in a central section of North Korea.
