 An Indonesian woman arrested for the murder of the half-brother of North Korea's leader has said she was given 400 Malaysian ringgit ($90; £72) to carry out a prank. 
 
 Indonesian embassy officials met Siti Aisyah, 25, on Saturday in the Malaysian capital. 
 
 She said she was given the cash to smear Kim Jong-nam's face with "baby oil" as part of a reality show joke. 
 
 Tests show Mr Kim was killed with the highly toxic nerve agent VX. 
 
 It is classified as a weapon of mass destruction by the United Nations.

 Unravelling the mystery of Kim Jong-nam's death 
 
 Mr Kim died last week after two women accosted him briefly in a check-in hall at Kuala Lumpur international airport. 
 
 The airport has been swept for toxic chemicals by a forensic team, the fire department and the Atomic Energy Licensing Board.

 There is widespread suspicion that North Korea was behind the attack, which it strongly denies. 
 
 A Vietnamese woman and a North Korean man have also been arrested in connection with the killing. 
 
 The Vietnamese foreign ministry confirmed that the Vietnamese national being held was Doan Thi Huong, born in 1988, saying she had told officials she thought she was taking part in a television prank. 
 
 At least seven other suspects are wanted by police.

 After a 30-minute meeting with Siti Aisyah on Saturday, Indonesian Deputy Ambassador Andreano Erwin said: "She only said in general that somebody asked her to do this activity. She only said in general she met with some people who looked Japanese or Korean. 
 
 "According to her, that person gave her 400 ringgits to do this activity... She only said she was given a kind of oil, like baby oil." 
 
 The officials said they did not see any physical signs that the suspect had been affected by the chemical.

 Malaysia's police chief Khalid Abu Bakar said on Friday that the presence of the nerve agent had been detected in swabs taken from Mr Kim's eyes and face. 
 
 Mr Kim had sought medical help at the airport, saying someone had splashed or sprayed him with liquid. He then had a seizure and died on the way to hospital. 
 
 What is the deadly VX nerve agent? 
 
 Image copyright Science Photo Library Image caption Molecular model of VX nerve agent shows atoms represented as spheres 
 
 The most potent of the known chemical warfare agents, it is a clear, amber-coloured, oily liquid which is tasteless and odourless 
 
 Works by penetrating the skin and disrupting the transmission of nerve impulses - a drop on the skin can kill in minutes. Lower doses can cause eye pain, blurred vision, drowsiness and vomiting 
 
 It can be disseminated in a spray or vapour when used as a chemical weapon, or used to contaminate water, food, and agricultural products 
 
 VX can be absorbed into the body by inhalation, ingestion, skin contact, or eye contact 
 
 Clothing can carry VX for about 30 minutes after contact with the vapour, which can expose other people 
 
 Banned by the 1993 Chemical Weapons Convention

 Who was Kim Jong-nam? 
 
 The well-travelled and multilingual oldest son of late North Korean leader Kim Jong-il, he was once considered a potential future leader. He has lived abroad for years and was bypassed in favour of his half-brother, Kim Jong-un. 
 
 He had been travelling on a passport under the name Kim Chol. North Korea has yet to confirm that the deceased was actually Kim Jong-nam.

 For many years, it was believed Kim Jong-nam was being groomed to succeed his father as the next leader. 
 
 But that appears to have come to an end in 2001 when Kim was caught sneaking into Japan on a fake passport. 
 
 He later became one of the regime's most high-profile critics, openly questioning the authoritarian policies and dynastic succession his grandfather Kim Il-sung began crafting in 1948.

 Two women implicated in the killing of the estranged brother of North Korea's leader will be charged with murder shortly, Malaysia's prosecutor says. 
 
 Attorney General Mohamed Apandi Ali said the women - from Indonesia and Vietnam - would be formally charged and could face death if convicted. 
 
 The women allegedly smeared a deadly chemical over Kim Jong-nam's face at a Malaysia airport earlier this month. 
 
 They have said they thought they were taking part in a TV prank. 
 
 "They will be charged in court under Section 302 of the penal code," the attorney general said, which is a murder charge with a mandatory death sentence if found guilty. 
 
 He said no decision had yet been taken on whether to charge a North Korean man, Ri Jong Chol, who is also being held over the killing. 
 
 That "depends on the outcome of the police investigation, which is still ongoing", Mr Apandi was quoted as saying by AFP news agency. 
 
 The two women - Doan Thi Huong from Vietnam and Siti Aisyah from Indonesia - are among some 10 suspects identified by Malaysia as being involved in the killing. 
 
 The other suspects include a senior official at the North Korean embassy in Kuala Lumpur and a staff member of the state airline. South Korea believes at least four suspects are North Korean spies.

 A high-level delegation from North Korea - led by the former ambassador to the UN - arrived in the Malaysian capital on Tuesday. 
 
 They said they were seeking the retrieval of the body and the release of Ri Jong Chol, as well as the "development of friendly relationships" between North Korea and Malaysia.

 North Korea has not confirmed that the person killed on 13 February at Kuala Lumpur airport was Kim Jong-nam, the half brother of leader Kim Jong-un, saying only he was a North Korean travelling on a diplomatic passport. 
 
 Kim Jong-nam, 42, was at a check-in desk for a flight to Macau, where he lives, when he was accosted. 
 
 He was smeared with a very high amount of the toxic nerve agent VX and died in pain within 15-20 minutes, Malaysia's health minister said on Sunday. 
 
 Who are Doan Thi Huong and Siti Aisyah?

 Little is known for definite about Doan Thi Huong and Siti Aisyah except that they had left their homes in different parts of Asia and were trying to make a living in Malaysia. 
 
 Malaysian police officials described Ms Huong, a 28-year-old from Vietnam, as an "entertainment outlet employee" while Ms Siti, 25 from Indonesia, was working in a hotel massage parlour. 
 
 It is clear they lived precarious existences, reports the BBC's Rupert Wingfield-Hayes who has been researching the story. 
 
 Ms Huong's Facebook page, in which she posted under the name Ruby Ruby, showed her posing in a number of selfies and glamour shots. There are rumours she once auditioned for Vietnam's version of Pop Idol.

 Her family said she left her home village in north Vietnam at 17 to study in the capital Hanoi, and had rarely returned home since. They said they were surprised to learn she was in Malaysia. 
 
 Her stepmother told BBC Vietnamese that the family were fed up with all the attention they had received but were grateful for the support of their neighbours. 
 
 "They are sympathetic because they don't understand how a daughter of a family with high moral values like us could become like that," Nguyen Thi Vy, 54, said. 
 
 Siti Aisyah was arrested for the killing along with her 26-year-old Malaysian boyfriend, who was later released on bail. 
 
 She told the Indonesian embassy officials that she thought she was taking part in a reality TV show, and had been paid 400 Malaysian ringgit ($90; £72) to smear what she thought was baby oil on to Mr Kim's face. 
 
 Ms Siti was out partying with her friends the night before the killing. A friend, who spoke anonymously, said they had been celebrating her birthday, which had been the day before. Film footage purportedly from the evening shows her talking with friends about becoming an internet star.

 KUALA LUMPUR, Malaysia (AP) — Malaysia's health minister said Sunday that the dose of nerve agent given to North Korean ruler Kim Jong Un's exiled half brother was so high that it killed him within 20 minutes and caused "very serious paralysis." 
 
 Kim Jong Nam died Feb. 13 at Kuala Lumpur's airport in what Malaysian police say was a well-planned hit by two women who wiped a liquid on Kim's face. Police revealed Friday that the banned chemical weapon VX nerve agent was used to kill Kim, raising the stakes in the case. 
 
 Health Minister Subramaniam Sathasivam said the dose of VX given to Kim was so high that he showed symptoms within minutes. Kim fainted at the airport clinic and died in the ambulance while en route to a hospital, he said. 
 
 "VX only requires 10 milligrams to be absorbed into the system to be lethal, so I presume that the amount of dose that went in is more than that," he said at a news conference. "The doses were so high and it did it so fast and all over the body, so it would have affected his heart, it would have affected his lungs, it would have affected everything." 
 
 Asked how long it took for Kim to die after he was attacked, Subramaniam said, "I would think it was about, from the time of onset, from the time of application, 15-20 minutes." 
 
 Malaysia hasn't directly accused the North Korean government of being behind the attack, but officials have said four North Korean men provided two women with poison to carry it out. The four men fled Malaysia on the same day as the killing, while the women — one from Indonesia and the other Vietnamese — were arrested. 
 
 Experts say the nerve agent used to kill Kim was almost certainly produced in a sophisticated state weapons laboratory and is banned under an international treaty. But North Korea never signed the treaty, and has spent decades developing a complex chemical weapons program. 
 
 Kim was not an obvious political threat to his estranged half brother, Kim Jong Un. But he may have been seen as a potential rival in North Korea's dynastic dictatorship, even though he had lived in exile for years. 
 
 North Korea has denied any role in the attack. 
 
 Earlier Sunday, Subramaniam said the state chemistry department's finding of the VX toxin confirmed the hospital's autopsy result that suggested a "chemical agent caused very serious paralysis" that led to death "in a very short period of time." The VX agent can lead to death very quickly in high doses, he said. 
 
 He said the final autopsy report would be submitted to police soon. 
 
 Subramaniam also said that there have been no reports of anyone else being sickened by the toxin, but that medical workers who attended to Kim would remain under observation for possible delayed effects. 
 
 Tens of thousands of passengers have passed through the airport since the apparent assassination was carried out. No areas were cordoned off and protective measures were not taken. 
 
 Early Sunday, more than a dozen officers in protective gear swept the budget terminal where Kim was attacked and said they found no traces of VX. 
 
 Abdul Samah Mat, the police official leading the investigation, said the terminal was "free from any form of contamination of hazardous material" and declared it a "safe zone" after a two-hour sweep. 
 
 He also said a condominium on the outskirts of Kuala Lumpur that was raided by police last week had been rented by the four North Korean suspects who left the country. He said police were still testing a seized substance for traces of any chemicals. 
 
 Abdul Samah said the Indonesian woman who was arrested, Siti Aisyah, vomited in a taxi on the way from the airport after the attack but is fine now. He said that more tests were needed to determine if the two arrested suspects were given antidotes so the nerve agent wouldn't kill them. 
 
 An antidote, atropine, can be injected after exposure and is carried by medics in war zones where weapons of mass destruction are suspected. 
 
 On Saturday, representatives from the Indonesian and Vietnamese embassies met with the two arrested women, who both said they thought they were part of a prank show. Aisyah said she was paid the equivalent of $90, according to Andriano Erwin, Indonesia's deputy ambassador to Malaysia.
– One of the women arrested in the airport slaying of the North Korean leader's half-brother says she thought she was smearing baby oil on her victim's face as part of a reality-show stunt. Siti Aisyah, who is being held in Malaysia, met with officials from her home country of Indonesia Saturday and told them she got paid $90 for what she thought was a harmless prank, reports the BBC. "She only said in general she met with some people who looked Japanese or Korean," says Indonesian Deputy Ambassador Andreano Erwin. "She only said she was given a kind of oil, like baby oil." On Friday, Malaysian officials announced that Kim Jong Nam was killed with a deadly nerve agent called VX. Authorities think Aisyah and another woman wiped it on his face in the crowded airport in Kuala Lumpur, perhaps as a kind of one-two punch—one woman smeared one compound, the other a second, and they combined to create the nerve agent. For the record, Malaysian officials have said they're not buying Aisyah's story that she was duped, notes the Guardian. One other person is in custody, a North Korean male who lives in Malaysia, and authorities say seven other North Korean suspects are being sought, reports the Wall Street Journal.
