North Koreans were involved in the murder of the half-brother of leader Kim Jong-Un, with four having fled the country on the day of the killing.Seoul said the announcement proved Pyongyang was behind the murder of Kim Jong-Nam, who died after being squirted in the face with an unidentified liquid at Kuala Lumpur International Airport on Monday.
The case has also sparked a diplomatic row between Pyongyang and Kuala Lumpur, after Malaysia rejected demands quickly to hand the body over to the North.
