MALAYSIAN Health Minister Subramaniam Sathasivam said yesterday that the dose of nerve agent given to Kim Jong Nam was so high that it killed him within 20 minutes after causing “very serious paralysis.”

Mr Kim, the brother of North Korea’s dynastic ruler Kim Jong Un, died on February 13 at Kuala Lumpur airport in what the authorities say was a well-planned hit by two women who wiped liquid on his face.

Police revealed on Friday that the banned VX nerve agent was used to kill Mr Kim.
