Kim Jong Un continues to rule with an iron fist, according to new reports coming out of South Korea, stating the North Korean leader has rid himself of one of his top lieutenants, Choe Ryong Hae.

South Korea's government said it's investigating reports than Un is on another deadly sweep of his inner circle, the Times reported, as Choi, Un's second-in-charge, hasn't been seen in weeks, and reportedly rubbed Un the wrong way with his leadership of various North Korean industries.
