Two women - an Indonesian and a Vietnamese - will be charged with murder over the killing in Malaysia of the estranged half-brother of North Korea's leader, Malaysia's attorney general says.
Police have said the women smeared VX nerve agent, a chemical on a UN list of weapons of mass destruction, on Kim Jong Nam's face in an assault recorded on security cameras in the Malaysian capital's airport on February 13.
US and South Korean officials believe Kim was the victim of an assassination orchestrated by North Korea. He had been living in exile, under Beijing's protection, in the Chinese territory of Macau, and had criticised the regime of his family and his half-brother Kim Jong Un.
Malaysian police arrested Doan Thi Huong, the Vietnamese woman, and Indonesian Siti Aishah in the days after the attack.
Police are also holding one North Korean man and have identified seven other North Koreans wanted in connection with a case that reads like the plot to a spy movie.
Both women will be formally charged on Wednesday under section 302 of the penal code, which carries the death penalty.
"I can confirm that," Attorney General Mohamed Apandi Ali told Reuters in a text message.
He said the North Korean in custody would not be charged yet. His remand period ends on Friday.
The security camera footage, which has been released in the media, showed two women assaulting Kim in the departure hall of Kuala Lumpur International Airport, and the victim stumbling into a clinic. He died within 20 minutes of the assault.
Both women have told diplomats from their countries that they had been paid to take part in what they believed was a prank for a reality television show.
Huong, the Vietnamese woman, was detained 48 hours after the murder in the same airport terminal where Kim was killed.
She is believed to be the woman wearing a white shirt emblazoned with the acronym "LOL", whose image was caught on security cameras while waiting for a taxi after the attack.
The daughter of a rice farmer in northern Vietnam, Huong had left home aged 18 more than a decade ago. She was described by Malaysian police as working for an "entertainment outlet", but they gave no details of where she had been employed or her immigration status.
A South Korean police official said Huong visited the holiday destination of Jeju Island in November for four days and they were looking into what she may have been doing there.
The Indonesian woman, Siti Aishah, was detained a day after Huong.
Old neighbours in a slum in Indonesia's capital, Jakarta, said before she left to find work in Malaysia, she had lived a quiet life, working from home in her ex-husband's family tailoring business before the couple separated in 2012.
Police have said the women knew what they were doing when they attacked Kim and were instructed to wash their hands afterwards.
