North Korea executes top education official, South Korea says

North Korea has executed its top education official, Kim Yong Jin, the South Korean Unification Ministry said Wednesday.

Unification Ministry spokesman Jeong Joon Hee held a press conference early on Wednesday to address media reports of a public execution of a senior-level North Korean official.

Two other officials, Kim Yong Chol, the head of North Korea's United Front Department (UFD), and a senior member of North Korea's propaganda department, received "revolutionary measures," commonly referred to as re-education, according to the spokesman.

No other details are immediately available.

Executions are widely considered a political tool forNorth Korean leader Kim Jong Un to consolidate his hold on power.

In May 2015, the country's defense minister, Hyon Yong-chol, was reportedly killed with an anti-aircraft gun after being accused of treason.

Two years earlier, Kim's uncle, Jang Song-thaek, was executed after being branded a "traitor for all ages."
