Attempted North Korean Coup?

Just one explanation for the movement of troops toward the North Korean capital.

The troop move drew the ire of Ri's main rivals Jang Song-taek, the uncle and guardian of leader Kim Jong-un, and Vice Marshal Choe Ryong-hae, Chosun.com reported. 

While it is clear that the situation on the Korean peninsula was unstable following the death of Kim Jong-il, the news agency makes no mention of whether the troop moves may have been linked to a possible coup d’état.
