South Korea says top North Korean official executed

Jeong Joon Hee, a spokesman for Seoul's Unification Ministry, told that Kim Yong Jin, a vice premier in North Korea's cabinet, had been executed

North Korea has executed a top education official and banished two other officials to rural areas for re-education, South Korean officials said on Wednesday.

If confirmed, they would be the latest in a series of killings, purges and dismissals carried out since North Korean leader Kim Jong Un took power in late 2011.

North Korea is a closed, authoritarian country with a state-controlled press that often makes it difficult for outsiders, and even North Korean citizens, to know what's happening in the government.

Rival South Korea, which runs several intelligence organisations mainly tasked with spying on North Korea, has a mixed record on reporting developments in the country. In May, a former North Korean military chief, who Seoul said had been executed, was found to be alive and holding several new senior-level posts.

Jeong Joon Hee, a spokesman for Seoul's Unification Ministry, told reporters on Wednesday that Kim Yong Jin, a vice premier in North Korea's cabinet, had been executed.

Jeong said Kim was in charge of education affairs, but refused to disclose why and when South Korea believes he was executed. He also didn't explain how his ministry obtained the information.

Little is known about Kim Yong Jin, who was last mentioned by North Korea's state news agency on June 15 when it reported he attended an event celebrating the 50th anniversary of the founding of North Korea's taekwondo federation.

The rival Koreas have shared the world's most heavily fortified border since the end of the 1950-53 Korean War, and they bar ordinary citizens from exchanging phone calls, letters and emails without special permission.
