Kim Jong-nam murder: Malaysia PM says citizens 'effectively hostages' in North Korea

Malaysian citizens are effectively being held hostage in North Korea, Prime Minister Najib Razak said on Tuesday after Pyongyang banned them from leaving the country in a row over the assassination of Kim Jong-Nam. 

"This abhorrent act, effectively holding our citizens hostage, is in total disregard of all international law and diplomatic norms," Razak said in a statement.
