The poison used to kill the estranged half brother of North Korea's
leader at a crowded air terminal in Malaysia last week was the banned
chemical weapon VX nerve agent, police said Friday. Eleven days after
the deadly toxin was used, they said they would eliminate any possible
remaining trace of it from the airport and other locations.
The revelation that VX nerve agent, deadly even in minute amounts, was used in the Feb. 13 attack boosted speculation that Pyongyang dispatched a hit squad to kill Kim Jong Nam, the outcast older sibling of North Korea's ruler.
