Deputy Prime Minister Datuk Seri Dr Ahmad Zahid Hamidi today said Kim Jong-nam's identity has been confirmed based on DNA sample comparison with one of the deceased's children.
Kim Han Sol appeared in a 40-second video last week in which he described his father's death as a "killing", although Pyongyang has repeatedly denied any involvement and said Kim Jong Nam, who was only identified as a North Korea "diplomat", had died of "natural causes".
Malaysian authorities say Kim was killed February 13 when two women smeared his face with the banned nerve agent VX in a crowded airport terminal.
The murder, and Malaysia's attempt to investigate North Koreans inside Pyongyang's embassy in Kuala Lumpur, has sparked a diplomatic meltdown between two countries with once strong ties.
No next of kin has come forward to claim the body. Malaysian officials have said Kim Jong Nam and Kim Chol are the same person but have declined to elaborate.
The 2019 Asia Cup final round qualifier between North Korea and Malaysia will be played on June 8 this year.
Zahid also said 50 North Korean workers in Sarawak would be deported because their work visas have expired, explaining that they are among more than 170 North Koreans working in mines in the Borneo state, in a government-to-government arrangement.
Malaysia has refused North Korea's request to release the body without an autopsy and investigation.More news: Manchester United midfielder Fellaini ends Premier League goal drought

Who killed Kim Jong-nam?
He was speaking to reporters after launching the new VIP facilities of the Kuala Lumpur International Airport (KLIA) here Wednesday. About 315 North Koreans are in Malaysia.
Two women - one Vietnamese and one Indonesian - have been arrested and charged with the murder.
It is reported that the North Korean workers are mainly in businesses including coal mining and construction.
Malaysian authorities have confirmed that the body of Kim Jong-nam has been embalmed.
Up to 100,000 North Koreans are believed to be working overseas and their remittances are a valuable source of foreign currency for the isolated regime.
There are nine Malaysians in North Korea - three embassy staff members and their family members. Airport surveillance footage shows them approaching the victim and apparently smearing his face with a piece of cloth.
