DPM: Kim Jong-nam used passport under the name Kim Chol

PUTRAJAYA: The North Korean who was killed at the Kuala Lumpur International Airport 2 (KLIA2) on Monday has been officially confirmed as Kim Jong-nam, the half-brother of North Korean leader Kim Jong-un.

Deputy Prime Minister Datuk Seri Dr Ahmad Zahid Hamidi said the confirmation was made based on the passport held by the victim as well as documents provided by the North Korean Embassy for verification.

He also confirmed that Kim Jong-nam had travelled using the "undercover" identity of Kim Chol.

"We have looked into the possibility that he travelled using a fake passport. I think he has two different identities. Probably this is an undercover document. But it is an authentic passport," he told a press conference here.

It is believed that Jong-nam had used the passport under the name of Kim Chol to travel incognito.

Ahmad Zahid gave assurance that security at KLIA2 "is at the highest level” despite the incident.

“Our airports' safety is at the highest level. We are equipped with high definition cameras. This is a very, very isolated case,” he said.

Jong-nam, 45, was killed by two women who splashed his face with a chemical at the KLIA2 departure hall at about 9am on Monday. He was about to leave for Macau.  The women later got into a taxi and fled.

One of the women, aged 29, who was in possession of a Vietnam travel document bearing the name of 'Doan Thi Huong' was arrested on Wednesday when she tried to board a flight out.

The other woman who has an Indonesian passport under the name of Siti Aishah was nabbed at 2am Thursday.

Both women have been remanded for seven days to assist in the investigations.

Police are looking for four men who were in the company of the two women at the airport when Jong-nam was killed.
