North Korea has staged 70 executions since current leader Kim Jong Un took power in late 2011, according to South Korea’s foreign minister.
Yun Byung-se also said at a forum in Seoul that Kim’s “reign of terror” is inspiring North Koreans working overseas to defect to the South.
Kim has removed key members of the old guard through a series of purges since taking over after the death of his father Kim Jong Il.
Experts claim Kim could be using fear to solidify his leadership, but those efforts could fail if he does not improve the country’s shattered economy.
