North Korean judo gold medalist Kye Sun Hui is hoping the national judo team she's been coaching for the London Games will replicate her Olympic achievement that turned her into a national hero 16 years ago.

A delegation of North Korean athletes left for London on Tuesday with hopes of returning to Pyongyang to the same hero's welcome Kye received after winning a gold medal at the 1996 Atlanta Olympics. Kye is now a national team coach.

North Korea's state media said the country is sending 51 athletes to compete in 11 events at the Olympics.

Kye said in an interview during a recent practice that North Koreans have a good chance to win medals in judo events as young athletes practiced the moves at the backdrop of a sign calling for an "athletic legend" in the authoritarian country.
