Child's DNA used to identify Kim Jong Nam's body, police say

Kim Jong Nam was killed February 13 in what Malaysian Prime Minister Najib Razak has called an assassination attempt. Kim was at Kuala Lumpur International Airport on his way to Macau when two women wiped his face with the highly lethal VX nerve agent, killing him in 20 minutes, Malaysian police said.

Both South Korea and Malaysia accuse Pyongyang of killing Kim. North Korea strongly denies the allegation.
