Seoul, South Korea (BBN)- North Korea's Defence Minister Hyon Yong-chol has been executed, South Korea's spy agency has told parliament, according to media reports.
South Korea's Yonhap news agency said MPs were told Mr Hyon had been killed on 30 April by anti-aircraft fire in front of an audience of hundreds, reports BBC.
He is believed to have been accused of showing disloyalty to North Korea's leader, Kim Jong-un.
Reports from North Korea are impossible to independently confirm.
There were few details of the reported execution, but Yonhap - quoting a briefing by the South Korea's National Intelligence Agency (NIS) -said Mr Hyon had fallen asleep during an event attended by Kim Jong-un and had not carried out instructions.
Analysis site NK News said Mr Hyon had last appeared in state media a day before the alleged execution date.
Mr Hyon is believed to have been a general since 2010, though little is known about him.
He served on the committee for late leader Kim Jong-il's funeral in December 2011, an indication of his growing influence.
He is believed to have been a general since 2010, and served on the committee for late leader Kim Jong-il's funeral in December 2011, an indication of his growing influence.
He was appointed defence minister last year.
Mr Kim has conducted a series of purges of close officials since becoming North Korea's leader.
The most notable was his uncle, Chang Song-thaek - once the country's second-most powerful figure.
He was arrested in December 2013 in front of a party meeting, found guilty of treason and immediately executed. The move was widely seen as the young Mr Kim stamping his authority.
Last month, a rights groups released satellite images it said showed unusual activity on a small arms range at the Kanggon army training area in October 2014.
The Committee for Human Rights in North Korea said the images - which could not be confirmed - showed large weaponry facing a very close target, a viewing area and several passenger vehicles.
It said the "most plausible explanation" for the image was a "gruesome public execution" by anti-aircraft fire.
