Kim Jong-un's reign of terror resumed this week as South Korea's spy agency reported the North Korean dictator ordered more executions.

According to the report, North Korea executed five senior officials using anti-aircraft guns because they made false reports that “enraged” leader Kim Jong-un, South Korea’s spy agency said Monday.

The comments by the National Intelligence Service in a private briefing to lawmakers come as Malaysia investigates the poisoning death of Kim’s estranged elder half-brother, Kim Jong-nam.

That investigation is still going on, but South Korea says it believes Kim Jong-un ordered the assassination, which took place February 13 at Kuala Lumpur’s airport.

The spy agency told lawmakers that five North Korean officials in the department of recently purged state security chief Kim Won-hong were executed by anti-aircraft guns because of the false reports to Kim, South Korean lawmaker Lee Cheol Woo said. It’s not clear what false reports they allegedly made, and the NIS didn’t say how it got its information.

South Korean spies have a spotty record when reporting about high-level events in authoritarian, cloistered North Korea.

North Korea fired Kim Won-hong in January, presumably over corruption, abuse of power and torture committed by his agency, Seoul said earlier this month. The fallen minister had been seen as close to Kim Jong Un. North Korea has not publicly said anything about Kim Won Hong or about the alleged executions in his department.

Lee also cited the NIS as saying that Kim Won-hong’s dismissal was linked to those false reports, which “enraged” Kim Jong-un when they were discovered.

Since taking power in late 2011, Kim Jong-un has reportedly executed or purged a large number of high-level government officials in what rival Seoul has called a “reign of terror.”
