Lee Ryeon-hee, 20, a high school student who defected from North Korea, places her hand over her heart in honour of the South Korean national flag during her graduation ceremony at the Hangyeore Middle and High School in Anseong, about 80 km (50 miles) south of Seoul, February 11, 2011. Forty-three students graduated from the school, which was built to educate North Korean teen defectors, five days before their former leader Kim Jong-il's birthday. They will go on to college or find employment. REUTERS/Jo Yong-Hak (SOUTH KOREA - Tags: POLITICS EDUCATION SOCIETY)
