The Director-General of Malaysian Health Ministry Noor Hisham Abdullah said on Tuesday that they had conducted the first autopsy of Kim Jong Nam and still awaited the results of a toxicology report.

A forensics team on February 15 conducted and completed the first autopsy on the body of a DPRK male believed to be Kim Jong Nam, doctor Abdullah said, adding that no second autopsy has been conducted. 

The press conference came a week after Kim Jong Nam, half-brother of DPRK leader Kim Jong Un, was murdered in Kuala Lumpur International Airport.

Police officers were present during the autopsy process, which is conducted in compliance with the international standard, Abdullah said. 

He told media they are still waiting for the toxicology report from Malaysia's Chemistry Department before they release the body to the DPRK.

The forensics team has not received any DNA samples from a next of kin, nor the medical records of the deceased, the doctor said.

Malaysian authorities have beefed up security at the hospital containing the body of Kim Jong Nam, as reports say his son, Kim Han Sol, will soon arrive to claim the body.

So far, there’s no indication that Kim Han Sol has arrived in the country. ‍ 

It’s been a week since news broke out that the half-brother of Kim Jong-Un had been assassinated in Kuala Lumpur's international airport. Here is what we know about the death of Kim Jong Nam. 

Last Monday morning Kim Jong Nam was at the budget terminal of Kuala Lumpur's main airport preparing to fly to Macau.  

He was approached by two women, one of whom grabbed him from behind and sprayed his face with an apparently poisonous liquid, according to police and leaked CCTV footage. 

Kim Jong Nam then approached airport staff, gesturing to his face in a bid to explain what happened, footage showed. The staff later led him to the airport clinic, where a picture released in Malaysian media shows him slumped in a chair.  Kim Jong Nam suffered a seizure and was rushed to hospital but died before he arrived.  

In the days following the attack, police announced they had arrested a 28-year-old Vietnamese woman called Doan Thi Huong, as well as 25-year-old Indonesian Siti Aishah and her Malaysian boyfriend.  Huong was caught on security footage from the airport wearing a T-shirt emblazoned with the word "LOL", police said. Later police arrested a 46-year-old DPRK national called Ri Jong Chol, who they said lived in Kuala Lumpur and worked in IT.  

Police are currently seeking four more men from the DPRK, who entered the country on different dates in the fortnight running up to the assassination, and all left on the day it was carried out.  The men returned to Pyongyang on a convoluted route via Indonesia, Dubai and Vladivostok, immigration officials and sources said.  

Seoul cited these developments as proof that the DPRK was behind the attack. But Pyongyang hit back, accusing the Malaysian investigation of being politically motivated.  

Malaysian authorities insisted a family member must come forward to provide a DNA sample before the body can be released - something they said has not yet happened. If no next of kin comes forward within a fortnight, police have said they would consider other options for the body.

A toxicology report should be released between one and two weeks after the post-mortem, the health minister has said on different occasions, which means there could be more detail about the kind of poison used as early as Wednesday.  ‍
