According to an overnight statement by the Malaysian police, Kim Jong Nam—half-brother of North Korean leader Kim Jong Un—was assassinated with the nerve agent VX at Kuala Lumpur International Airport.
VX is one of the high-end chemical warfare agents developed and produced in large quantities by the USA, USSR and some secondary powers during the cold war. Former military chemical weapon arsenals are being eliminated under the Chemical Weapons Convention. The Democratic People’s Republic of Korea (DPRK), of course, is together with Egypt, Israel and South Sudan one of the four hold-out states. It is widely believed to have a significant chemical warfare capacity, but how militarily effective it might be is anyone’s guess.
Commentators will happily inform you that it possesses the world’s largest stockpile, which is as good as meaningless given that all other arsenals have been almost entirely eliminated under international supervision. BBC World already broadcast a report in which an unidentified ‘expert’ said it had to be a nation-state because its synthesis is far too complex for your backroom.
However, the substance is not unknown in terrorism: Aum Shinrikyo synthesised somewhere between 100 and 200 grammes of the substance between 1993 and 1995. It tried to assassinate several opponents by spraying it in the face of the victim with a syringe. Only one person died; the others survived. It always appeared technological overkill: had the cult used more ‘traditional’ assassination weapons, such as knives or guns, their attacks would have been far more lethal.
Many questions; few answers so far
As the information stands right now, the Malaysian police’s claim is remarkable for what it does not say. The preliminary toxicology report reportedly states that traces of VX were detected on swabs of the dead man’s face and eyes. If this is the case, then the following questions require an answer:
- Why were there no previous descriptions in press reports of symptoms typically associated with nerve agent exposure (spasms, foaming, discolouration, etc.)?
- Why did it take 9 days since the assassination on 13 February before the poison was confirmed?
- Why did the preliminary toxicology report (or at least the police officer) not mention physiological consequences of nerve agent exposure, such as increased acetylcholine levels (which is responsible for the spasms)?
- What is meant by ‘traces’? Residue? Or small amounts? VX is a pretty persistent agent that can last for days. Rubbing the agent in the face suggests an area with a rather high concentration of the agent, even if the amount was limited.
- Why did the assassin not display any of those symptoms? Was she wearing gloves or was the agent contained in a capsule? (And if she was wearing gloves, were they then not found? Or fragments of a capsule?) Did she receive a nerve agent pretreatment antidote? There were some reports of vomiting, but was this reaction related to nerve agent exposure? Any splash of a tiny droplet anywhere on her body would have resulted in some symptoms of varying degree. She was jailed, but nothing to such effect was reported.
- There was apparently no decontamination effort at the airport. So, were first responders or medical staff at the airport clinic, police officers and other persons who came to the victim’s assistance or were in his vicinity affected through secondary contamination? No reports, thus far.
- Have samples been sent to one of the top-level OPCW certified laboratories, such as the Verification Laboratory, Defence Medical and Environmental Research Institute, DSO National Laboratories in neighbouring Singapore (with or without involvement of the OPCW)?
- Why did the Malaysian authorities say earlier today that they would sweep the airport and other locations for radioactive material? And apparently not for VX traces?
These, and I am sure, many more questions require clear answers before we can arrive at reasonable conclusions. More to come over the next days and weeks …
