Kim Jong Un 'executes 70 officials'
North Korean leader Kim Jong Un has executed 70 officials since taking power in late 2011 in a "reign of terror" which far exceeds the bloodshed of his dictator father's early rule, South Korean officials said.
South Korean foreign minister Yun Byung-se, at a forum in Seoul, compared Kim Jong Un's 70 executions with those of his late father, Kim Jong Il, who, he said, executed about 10 people during his first years in power.
An official from South Korea's National Intelligence Service confirmed that the spy agency believes the younger Kim has executed about 70 officials but would not reveal how it obtained the information.
Mr Yun also said the younger Kim's "reign of terror affects significantly" North Koreans working overseas by inspiring them to defect to the South.
North Korea, an authoritarian nation ruled by the Kim family since 1948, is secretive about its government's inner workings, and information, even that collected by South Korean intelligence officials, is often impossible to confirm.
Kim Jong Un has removed key members of the old guard through a series of purges since taking over after the death of Kim Jong Il.
The most spectacular purge to date was the 2013 execution of his uncle, Jang Song Thaek, for alleged treason. Mr Jang was married to Kim Jong Il's sister and was once considered the second most powerful man in North Korea.
South Korea's spy agency told politicians in May that Kim ordered his then-defence chief, Hyon Yong Chol, to be executed with an anti-aircraft gun for complaining about the young ruler, talking back to him and sleeping during a meeting.
Experts say Kim could be using fear to solidify his leadership, but those efforts could fail if he does not improve the country's shattered economy.
