Malaysia hunting for four North Korean suspects over Kim Jong Nam murder

Malaysian police said on Sunday they are looking for four North Korean suspects in connection with the murder of the estranged half-brother of North Korean leader Kim Jong Un.

The suspects fled Malaysia on the day of the killing, but police would not reveal the flight’s destination, just saying that they were coordinating with Interpol to track them down.

Malaysian police arrested a North Korean man on Friday in connection to the murder of Kim Jong Nam, while a Vietnamese woman and an Indonesian woman have also been arrested. A Malaysian man is being detained to facilitate the investigation.

The four suspects, who are all male and aged between 33 and 57, flew out of the country on the same day that Mr Kim died, police chief Tan Sri Noor Rashid Ibrahim told a news conference. In addition, another three North Koreans are being sought to assist police with their enquiries.

Kim Jong Nam died on Monday after being assaulted at Kuala Lumpur International Airport, where he was catching a flight to Macau. South Korean and U.S. officials have said he was assassinated by North Korean agents using what was thought to be a fast acting poison.

“I can confirm today that they (four North Korean suspects) have left our country the very same day the incident happen,” deputy inspector-general of police Noor Rashid Ismail told reporters at a press conference.

“The four suspects are holding normal passports, not diplomatic passports,” he said.

“Next plan is to get them. We of course have international cooperation especially with Interpol, bilateral involvement with the country involved, we will go through those avenues to get the people involved.”

Malaysian police said the cause of death was still not known and that they were waiting for pathology and toxicology tests after conducting a post-mortem.

Pyongyang has demanded Mr Kim's body be returned but Malaysia has refused the request, saying it must remain in the country until identified through a DNA sample from a family member.

A diplomatic spat between North Korea and Malaysia over the body has escalated. North Korea has said it would reject Malaysia's autopsy report and accused Malaysia of "colluding with outside forces" - a veiled reference to rival South Korea.

The Malaysian police said they were trying to contact the next-of-kin of Kim Jong Nam. "The body must be identified. The most eligible to identify the body physically is the next-of-kin," Noor Rashid said.

"We will verify again through scientific means, so it is very important for close family members to come forward to assist us in process of identification base on legal procedures under Malaysian law."

The police is giving the next-of-kin two weeks to claim the body. South Korea's intelligence agency told lawmakers in Seoul that Kim had been living with his second wife in the Chinese territory of Macau, under China's protection.

Kim Jong Nam, the eldest son of the late North Korean leader Kim Jong Il, had spoken out publicly against his family's dynastic control of isolated, nuclear-armed North Korea.

South Korean intelligence chiefs believe his killing was an assassination ordered by Kim Jong-Un some time ago because he perceived his half-brother to be a threat. The young, unpredictable North Korean leader had issued a "standing order" for his elder half-brother's assassination, and that there had been a failed attempt in 2012.

The North Korean leader has overseen a purge of various "traitors", including his uncle General Jang Song-Thaek, who was executed by machine gun in 2013.
