North Korean dictator Kim Jong Un ordered the head of his military to be killed by anti-aircraft gunfire for “insubordination and treason” and for falling asleep at a meeting while the “Supreme Leader” was speaking, according to South Korea’s intelligence agency Wednesday.

The man killed, General Hyon Yong Chol, was most recently the chief of North Korea’s People’s Armed Forces which made him second in commander of the country’s military. According to South Korean spies, he was killed by firing squad in front of hundreds of military officers in Pyongyang last month.

Several sources have confirmed — including area media outlets who even produced photographic evidence — that Chol was caught dozing off two seats from Un while being briefed about military matters.

The way he was executed, though, was even more grisly than a regular firing squad. As unbelievable as that statement is. But it was.

From the Washington Post:

North Korean defectors have recently been saying that executions are being carried out in increasingly spectacular style — including with high-caliber artillery — to make an example of those who fall afoul of Kim’s monolithic system.

A recent report from the U.S. Committee for Human Rights in North Korea contained satellite imagery apparently showing several people standing in front of anti-aircraft machine guns at a military training area 13 miles north of Pyongyang in October last year.

Another insane display that pretty much falls in line with Un’s recent tantrums and irrational, paranoid decisions. Perhaps his master plan?

This report is the latest suggestion that Kim, the 30-something third-generation leader of North Korea, is tightening his grip on power. Kim, who succeeded his father, Kim Jong Il, at the end of 2011, had his uncle and mentor, Jang Song Taek, executed at the end of 2013, because he had disobeyed orders and worked in secret to build up his base of power.

Since taking over the country ruled through a bizarre personality cult, Kim has ordered a series of reshuffles, purges and apparent executions as a way to consolidate his authority.
