KUALA LUMPUR, MALAYSIA - Malaysia’s health minister says the dose of poison given to North Korean ruler Kim Jong Un’s half brother was so high that it killed him “within 15-20 minutes.”
Kim Jong Nam died February 13 at Kuala Lumpur’s airport. Friday’s revelation by Malaysian police that the banned chemical weapon VX nerve agent was used to kill Kim raised the stakes significantly in the case.
Health Minister Subramaniam Sathasivam said Sunday that the dose of VX given to Kim was so high that it “would have affected his heart, it would have affected his lungs, it would have affected everything.”
Subramaniam said it required only 10 milligram of VX for it to be lethal “so I presume that the amount of dose that went in is more than that.”
The killing of Kim Jong Nam took place amid crowds of travelers at Kuala Lumpur's airport and appeared to be a well-planned hit. Kim died on the way to a hospital, within hours of the attack.
Tens of thousands of passengers have passed through the airport since the apparent assassination was carried out. No areas were cordoned off, and protective measures were not taken. Subramaniam said there had been no reports so far of anyone else being sickened by the toxin.
Late Saturday, however, police said they would begin a sweep of the terminal where Kim was attacked. It started around 2 a.m. Sunday and involved officers from the police's chemical, biological, radiological and nuclear teams, as well as the fire department's hazardous materials unit and the government's atomic energy board. Although VX is not radioactive, police said the radiological team and the atomic energy board were involved as a precaution.
Abdul Samah Mat, the police official leading the investigations, said a two-hour sweep by more than a dozen officers in protective gear detected no hazardous material. He declared the terminal a "safe zone."
Earlier Saturday, police warned they would issue an arrest warrant for a North Korean diplomat if he refused to cooperate with the investigation into the attack.
Experts say the nerve agent used to kill Kim, banned under an international treaty that North Korea didn't sign, was almost certainly produced in a sophisticated state weapons laboratory. North Korea has spent decades developing a complex chemical weapons program.
Kim was not an obvious political threat to his estranged half brother, Kim Jong Un. But he may have been seen as a potential rival in North Korea's dynastic dictatorship, even though he had lived in exile for years. North Korea has denied any role in the attack.
Malaysia said earlier in the week that Hyon Kwang Song, a second secretary at the North Korean Embassy in Kuala Lumpur, was wanted for questioning. But authorities acknowledged at the time that he had diplomatic immunity and they couldn't compel him to appear.
On Saturday, Malaysia's tone changed.
Abdul Samah, the police official, said authorities would give the diplomat reasonable time to come forward. "And if he failed to turn up ... then we will go to the next step by getting a warrant of arrest from the court," he told reporters.
Lawyer Sankara Nair, however, noted that diplomats have immunity privileges even in criminal cases. "Police can apply for a warrant, but it can easily be set aside by the embassy," he said.
Malaysia hasn't directly accused the North Korean government of being behind the attack, but officials have said four North Korean men provided two women with poison to carry it out.
The four men fled Malaysia shortly after the killing, while the women — one from Indonesia and the other Vietnamese — were arrested.
On Saturday, representatives from the Indonesian and Vietnamese embassies in Malaysia met with the two women.
Indonesia's deputy ambassador, Andriano Erwin, told reporters later that Siti Aisyah said she had been paid the equivalent of $90 for what she believed was a harmless prank. Aisyah, 25, said she had been introduced to people who looked like Japanese or Koreans who asked her to play a prank for a reality show, according to Erwin.
Asked if she knew what was on her hands at the time of the attack, Erwin said: "She didn't tell us about that. She only said that it's a kind of oil, baby oil, something like that."
An odorless chemical with the consistency of motor oil, VX is an extremely powerful poison; an amount no larger than a few grains of salt is enough to kill. It can be inhaled, swallowed or absorbed through the skin. Then, in anywhere from a few seconds to a few hours, it can cause a range of symptoms, from blurred vision to a headache. Enough exposure leads to convulsions, paralysis, respiratory failure and death.
The Vietnamese woman who was arrested, Doan Thi Huong, also thought she was taking part in a prank, Vietnam's Foreign Ministry said Saturday.
In grainy surveillance footage, the women appear to smear something on Kim's face before walking away in separate directions. Malaysian police said the attackers knew what they were doing and had been trained to go immediately to the bathroom and clean their hands.
Experts say the women must have taken precautions so the nerve agent wouldn't kill them.
An antidote, atropine, can be injected after exposure and is carried by medics in war zones where weapons of mass destruction are suspected.
Also Saturday, police confirmed that a raid earlier in the week on the outskirts of Kuala Lumpur was part of the investigation. Abdul Samah, the police official, did not specify what authorities found there, but said the items were being tested for traces of any chemicals.
