Malaysian police said four North Korean men were involved in killing the half-brother of North Korean leader Kim Jong-un.
 
Two women from Indonesia and Vietnam are standing trial for the murder of Kim Jong-nam, who died in February at Kuala Lumpur International Airport after VX nerve agent was rubbed on his face. 
 
A senior police officer named four North Korean men in court on Monday, saying they fled Malaysia after the murder. 
 
The men are Ri Jae-nam, Hong Song-hac, Ri Ji-hyon and O Jong-gil. It is the first time that Malaysian police identified the four suspects as the North Korean nationals who fled Malaysia after the murder.
 
Malaysian police presented CCTV footage of the suspects meeting a North Korean embassy official and an official from the national airline Air Koryo at the airport's main terminal shortly after the attack.
