Kim Jong Nam was identified publicly last week after Malaysia received DNA sample

South Korea and Malaysia accuse North Korea of killing Kim; Pyongyang denies it

Kuala Lumpur, Malaysia CNN  — 

The body of Kim Jong Nam, the estranged half brother of North Korean leader Kim Jong Un slain last month, was identified using a DNA sample from his son, Malaysian authorities said Thursday.

The sample was obtained by Malaysian authorities who went overseas to get it, Malaysia Deputy Prime Minister Ahmad Zahid Hamidi said.

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.

Malaysian authorities didn’t publicly identify Kim’s body until last week after obtaining a DNA sample “from the child of the deceased,” Malaysian Deputy Prime Minister Ahmad Zahid Hamidi said Wednesday.

He declined to elaborate on how the DNA sample was obtained.

Kim’s family is believed to be in hiding. His son Kim Han Sol emerged publicly for the first time after his father’s death last week in a 40-second video posted online by a group called Cheollima Civil Defense.

It’s not clear when the video was shot, but a South Korean National Intelligence Service spokesman verified the son’s identity to CNN.

The row over the body

The decision to hold Kim Jong Nam’s body – and conduct an autopsy – angered the North Koreans. They wanted the body and said Malaysia should hand it over because he was a North Korean national.

But Malaysian authorities would only release it if a DNA match was provided.

This diplomatic row culminated in both countries issuing dual travel bans – Malaysians were prohibited from leaving North Korea and North Koreans couldn’t travel out of Malaysia.

Nine Malaysians are in North Korea. It’s not clear how many North Koreans are in Malaysia, but police believe three people wanted for questioning in Kim’s killing are holed up in the North Korean Embassy in Kuala Lumpur.

There are four suspects at large, believed to be back in North Korea, and two people in custody regarding the case.

The international police service INTERPOL issued red notices for the four of them Thursday.

Red notices are described by the US Justice Department as the “closest instrument to an international arrest warrant in use today.” But they only pertain to countries that are INTERPOL members, which North Korea is not.

Siti Aisyah of Indonesia and Doan Thi Huong of Vietnam have both been charged with murder and face the death penalty if convicted.

Authorities from both countries have said the women believed they were participating in a prank TV show, but Malaysian authorities do not believe that’s true.
