NK defectors plead for help

North Korean defectors Cha Sung-hyuk, 11, second from right, and his uncle Ko Kyung-ho, second from left, plead for help, during a press conference at the Korea Press Center in central Seoul, Tuesday, for Cha’s mother, Ko Kyung-hee, who is now allegedly being held in a political prisoner camp in North Korea. The mother defected to the South in 2011, but returned to North Korea a year later because she worried about possible persecution of her family. However, she was arrested, tortured and put in a prisoner camp, according to her family. Her son and brother defected to the South in December. / Yonhap
