Who produced the VX poison that killed Kim Jong-nam?

Malaysian police announced earlier Friday their findings that a highly toxic nerve agent known as VX was used to kill Kim.

Malaysian police announced on Friday that tests on the eyes and face of a North Korean national had been conducted.

Kim Jong-nam was poisoned at Kuala Lumpur airport after two women wiped a toxin on his face.

Police are trying to locate the eight suspect, another North Korean, Ri Ji U, whose whereabouts are unknown, Samah said on Saturday.

Two women suspects have been detained by Malaysian police in connection with the killing.

One man wanted for questioning, who is believed to be still in Malaysia, is senior North Korean embassy official Hyon Kwang Song.

The revelation that VX nerve agent killed Kim has boosted speculation that North Korea had dispatched a hit squad to Malaysia to kill Kim, whose younger half brother is Kim Jong Un.

Most of the world has banned chemical weapons like VX, but North Korea - along with Egypt and Israel - have not signed on to the global chemical weapons pact. The Nuclear Threat Initiative reports North Korea possesses between 2,500 and 5,000 tons of VX.

"The ambassador has been informed of the process involved (in the police investigation) but he continues to be delusional and spew lies and accusations against the government of Malaysia", said Malaysian Foreign Minister Anifah Aman.

Mr Khalid has previously said the woman who ambushed Mr Kim from behind clearly knew she was carrying out a poison attack, dismissing claims that she thought she was taking part in a TV prank.

The death of Kim Jong Nam, whose daylight assassination in a crowded airport terminal seems straight out of a spy novel, has unleashed a diplomatic crisis that escalates by the day. Kim was dead within hours of the attack, in which two women went up behind him and appeared to smear something onto his face before walking away in separate directions. North Korea has not acknowledged his death.

Huong was described by police as an "entertainment outlet employee", but they did not give details of where she had been employed or what her immigration status was.

Considered twice as more toxic than sarin, the VX nerve agent is one of the most toxic and fastest acting chemical warfare agents, according to the US Centers for Diseases Control and Prevention.
