Kim Jong-un’s powerful uncle has been “dismissed” from his post at the helm of North Korea’s military, the reclusive nation's state-run media reported Tuesday. Chang Song-thaek is Kim’s uncle by marriage, and he was one of seven senior figures to accompany Kim’s father’s hearse in Pyongyang two years ago. An economic reformer, Chang normally handles discussions with China, North Korea’s only major ally. His removal from power would be the biggest shakeup in Pyongyang since Kim took power. The National Intelligence Agency also announced Tuesday that two of Chang’s closest aides were executed in public for corruption in November.
