Kim Jong-Un executes defence minister

Hyon Yong Chol, 66, who headed the country's military, was killed late last month for disobeying Kim Jong Un and falling asleep during a meeting, according to a South Korean news agency.

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.

The reported execution comes after South Korea's spy agency said late last month that Kim ordered the execution of 15 senior officials as punishment for challenging his authority.

Hyon was said to have shown disrespect to Kim by dozing off at a military event.
