On 13 February 2017, Kim Jong-nam, half-brother of North Korean leader Kim Jong-un, died after an assault at Kuala Lumpur International Airport in Malaysia. According to the authorities he was murdered by poisoning with VX which was found on his face. The authorities further reported that one of the women suspected of applying the nerve agent experienced some physical symptoms of VX-poisoning. The director of a non-proliferation research program of the Middlebury Institute of International Studies at Monterey stated that VX fumes would have killed the suspected attackers even if they had been wearing gloves, suggesting that the VX was applied as two non-lethal components that would mix to form VX only on the victim's face.
