The dose of nerve agent that was sprayed in Kim Jong-nam’s face was so high he was dead within 20 minutes, authorities have said.
Kim Jong-un’s exiled half-brother was attacked in what police say was a well-planned hit by two women at Kuala Lumpar’s airport on February 13.
He was struck by a banned chemical weapon VX, in a dose so high that he showed symptoms within minutes, according to Health Minister Subramaniam Sathasivam.
He said in a news conference: ‘VX only requires 10 milligrams to be absorbed into the system to be lethal, so I presume that the amount of dose that went in is more than that.
‘The doses were so high and it did it so fast and all over the body, so it would have affected his heart, it would have affected his lungs, it would have affected everything.’
Asked how long it took for Kim to die after he was attacked, he added: ‘I would think it was about, from the time of onset, from the time of application, 15-20 minutes.’
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 on the same day as the killing, while the women — one from Indonesia and the other Vietnamese — were arrested.
Experts say the nerve agent used to kill Kim was almost certainly produced in a sophisticated state weapons laboratory and is banned under an international treaty.
But North Korea never signed the treaty, and has spent decades developing a complex chemical weapons program.
North Korea has denied any role in the attack.
