A powerful uncle of North Korean leader Kim Jong-un has been removed from his post, South Korean media reports say.
Citing South Korea's intelligence agency, they say Chang Song-thaek, 67, lost his position as vice-chairman of the North's top military body.
Two close aides were also executed for corruption, according to the reports.
If confirmed, Mr Chang's removal would be the biggest upheaval in North Korea's leadership since Mr Kim succeeded his father, analysts say.
Kim Jong-un took over after Kim Jong-il died in 2011.
