VX nerve agent used to kill Kim Jong Nam, police say
By Joshua Berlinger, CNN
Malaysian police said in a statement Friday that tests on Kim’s eyes and face revealed the presence of the substance.
Nerve agents are the most toxic and fast-acting substance known in chemical warfare — and VX is the most potent of all of them, according to the US Centers for Disease Control and Prevention (CDC).
Kim, the estranged half-brother of North Korean leader Kim Jong Un, died on February 13 before he was scheduled to board a flight from Kuala Lumpur to Macau.
