In Jong-nam murder case, cops confirm taking samples from condo

A senior Malaysian government official said Mr Kang had been shown a "yellow card", adding: "If he repeats the baseless allegations, he will be expelled".

Two women suspects have been detained by Malaysian police in connection with the killing.

The 25-year-old woman also said "they were maybe Japanese or Korean", the Indonesian diplomat was quoted as saying.

The Malaysian police have arrested a Vietnamese woman and an Indonesian woman suspected of smearing the chemical on his face.

Jong Nam, 46, was killed while preparing to board a flight to Macau, where he lived in exile with his family under the protection of Beijing.

Police are investigating whether it was brought into Malaysia or made there before allegedly being used by North Korean assassins. North Korea, however, is one of six countries that are not signatories to the convention.

North Korea is believed to have the world's third-largest stockpile of chemical weapons, according to the Nuclear Threat Initiative project, while South Korean analysts have identified sarin and VX as the focus of Pyongyang's programme.

This would fit with Kim Jong Un's track record of getting rid of potential contenders for the leadership of North Korea.

Notably, Kim Jong-nam was known to be under the Chinese government's protection - so North Korea's ruler crossed his ultimate protector by ordering the murder. Police said on Thursday that an interview request has been sent to the embassy, but a spokesperson there said nothing had been received.

Police had previously said that the women were paid to carry out the assault and had been told to wash their hands before fleeing from the airport.

CCTV footage shows Kim Jong-nam was approached from behind by a woman who wiped her hands on his face on February 14 at the Kuala Lumpur airport.

"The US government had no plans to engage in track 2 talks in NY", the official said, while reportedly denying commenting on individual visa cases. He is seen pointing to his face while speaking with airport officials and guards.

He suffered a seizure and was dead before he reached hospital.

Toxicology reports coming from Malaysia indicated that he was attacked with a VX nerve agent, this is now classified as a weapon of mass destruction by the United Nations. It is banned worldwide except for official research purposes.

Experts describe it as a "very toxic" chemical that can kill even in very small amounts. An odorless chemical, it can be inhaled, swallowed or absorbed through the skin.
