Malaysia's health minister Subramaniam Sathasivam has reportedly said that the dose of poison given to North Korean ruler Kim Jong-un's half-brother Kim Jong-nam was so high that it killed him within 15-20 minutes. Malaysian police reportedly revealed that the banned chemical weapon VX nerve agent was used to kill Kim. The minister reportedly said on Sunday that the dose was so high that it "would have affected his heart, it would have affected his lungs, it would have affected everything."
