Kim Jong-nam was killed by VX nerve agent, Malaysian toxicology reports say.
The half-brother of North Korean leader Kim Jong-un died last week after two women accosted him briefly in a check-in hall at a Kuala Lumpur airport.
The toxicology reports indicate Kim Jong-nam was attacked using VX nerve agent, which is classified as a weapon of mass destruction by the UN.
There is widespread suspicion that North Korea was responsible for the attack, which it fiercely denies.
North Korea responded furiously to Malaysia’s insistence on conducting a post-mortem examination and has accused Malaysia of having “sinister” purposes.
Malaysia’s police chief Khalid Abu Bakar said on February 24 that the presence of the nerve agent had been detected in swabs taken from Kim Jong-nam’s eyes and face.
One of the women Kim Jong-nam interacted with at the airport on February 13 had also fallen ill with vomiting afterwards, he added.
Khalid Abu Bakar said other exhibits were still under analysis and that police were investigating how the banned substance might have entered Malaysia.
