A South Korean think tank says that doubts surrounding the leadership of Kim Jong-un are spreading among North Korean officials due to his extreme reign of terror.
 
Chief researcher Lee Soo-seok from the Institute for National Security Strategy on Wednesday presented the assessment in a statement released ahead of a forum set for Thursday.
 
The researcher said that top officials are hesitant to give advice to Kim and obeying him like sheep for fear of execution.
 
The researcher said that North Korean officials stationed abroad are defecting from the country due to growing doubts over Kim’s leadership.
 
He added that Kim Jong-un has executed more than 100 party and military officials since he took office in late 2011.
