Two women accused of murdering the half-brother of North Korean leader Kim Jong Un will stand trial in October.
Indonesian Siti Aisyah and Vietnamese Doan Thi Huong are accused of smearing Kim Jong Nam's face with the banned VX nerve agent at a crowded airport terminal in Kuala Lumpur, Malaysia, on February 13.
Mr Kim died about 20 minutes later.
The women, who face a possible death penalty if convicted, say they were duped into thinking they were playing a harmless prank for a hidden-camera TV show.
Judge Azmi Ariffin estimated the trial would last for two months.
The women appeared in court in Shah Alam wearing traditional Malay dresses, smiling at their lawyers and embassy officials. They were handcuffed as they were led to the dock.
But after the judge left the room, Aisyah was in tears as her lawyer debriefed her.
The two women are the only suspects in custody in a killing that South Korea's spy agency said was part of a five-year plot by Kim Jong Un to kill a brother he reportedly never met.
Malaysian police have said four North Korean suspects fled the country on the same day Kim Jong Nam was killed.
North Korea has a history of ordering killings of people it views as threats to its regime.
While Kim Jong Nam was not thought to be seeking influence, his status as eldest son in the current generation of North Korea's founding family could have made him appear to be a danger to his half brother's rule.
Pyongyang has denied any role in the killing and has not even acknowledged that the dead man was Kim Jong Nam.
