Reuters: North Korea has executed its defense chief on treason charges by putting him in front of an anti-aircraft gun at a firing range, Seoul’s National Intelligence Service (NIS) told lawmakers.

Hyon Yong Chol, 66, who headed the isolated country’s military, was purged late last month for disobeying Kim Jong Un and falling asleep during a meeting at which North Korea’s young leader was present, according to South Korean lawmakers briefed in a closed-door meeting with the spy agency on Wednesday.

His execution, the latest of a series of high-level purges since Kim took power in 2011, was watched by hundreds of people, they said.
