Kim Jong has 'executed or banished over 100 members of uncle's family' More than 100 members of the family of the executed uncle of Kim Jong-Un have been killed or arrested, a report claims. A news website for North Korean defectors, Daily NK, reported that members of Jang Song-Thaek's family were rounded up by the dozen following his arrest and subsequent death in December. Although South Korean news agencies have published unconfirmed information from North Korea in the past, the report from Daily NK back up the claims of a 'purge' of Jang's family. The president of South Korea, Park Geun-Hye, has previously spoken of her fear of purges among the powerful in the North. 'North Korea is now engaged in a reign of terror while carrying out a massive purge to consolidate the power of Kim Jong-Un,' she told a cabinet meeting. Since Kim Jong-Un came to power in April 2012 he has shown himself to be a brutal tyrant, having executed or demoted a long list of people he has deemed a threat. According to newspaper Chosun Ilbo, Ri Yong-ho, Kim Yong-chun, U Tong-chuk, and Kim Jong-gak, all part of his father Kim Jong-il's inner circle, were handpicked to groom the 31-year-old leader, but have since disappeared or been demoted. As well as his uncle, Jang Song-Thaek, other high-ranking members of the military have been purged, including three defence ministers and three chiefs of the army's general staff. Kim Chol, the vice minister of the army, was reportedly put to death in October 2012 by soldiers firing mortar rounds at him. In August last year, members of a female musical group, Unhasu Orchestra - which included his ex-girlfriend - were reportedly publicly machine-gunned apparently for watching pornography and filming themselves naked. There are said to have been between 40 to 80 public mass executions in North Korea in 2013. The family were recalled to the Pyongyang area of the country by Ministry of State Security troops in early December before being killed, sources said. Kim Jong-Un's former mentor Jang was accused of a number of crimes against the state. Jang is the husband of Jong-un's biological aunt, the sister of his father Kim Jong-Il.
