Two women charged with assassinating the estranged half-brother of North Korea's leader were ordered to enter their defence in their long-running trial Thursday, marking the next chapter in a story that has gripped the world.
A Malaysian judge ruled there was enough evidence to support a murder charge against Siti Aisyah from Indonesia and Doan Thi Huong from Vietnam.
The women are accused of smearing a deadly nerve agent on Kim Jong Nam's face as he waited for a flight at Kuala Lumpur airport.
Here is a timeline of key events in the killing.
A portly North Korean man, later identified as Kim Jong Nam, dies after being attacked at Kuala Lumpur International Airport on February 13. Seoul points the finger at its northern neighbour and says it was a political hit aimed at weeding out potential rivals to North Korean leader Kim Jong Un.
Malaysian detectives track down two migrant women -- one Vietnamese and one Indonesian -- who they say are seen on CCTV carrying out the attack.
The two women, who are eventually charged with murder, say they had been paid to carry out what they thought was a prank for a reality TV show.
An autopsy reveals Kim died from exposure to the VX nerve agent, an artificial chemical so deadly it is banned under international treaty and classified by the UN as a weapon of mass destruction.
Kuala Lumpur arrests North Korean citizen Ri Jong Chol in connection with the murder. Over the following days investigators say diplomats and airline employees from the isolated regime are also wanted for questioning. All are holed up at the North Korean embassy or have already left the country.
North Korea pours scorn on what it calls "absurd" claims that VX was used, saying South Korea and the US are mounting a smear campaign against it.
Pyongyang insists the dead man was called Kim Chol and demands his body be returned. Investigators refuse to release the corpse.
Malaysia cancels a visa-free travel deal with North Korea and deports North Korea's ambassador. Pyongyang hits back, expelling Malaysia's envoy.
Tensions escalate after North Korea bans all Malaysians from leaving Pyongyang. Malaysia retaliates and the international community calls for calm amid allegations of hostage holding.
In early March, Ri Jong Chol is released from custody and deported from Malaysia. Frustrated Malaysian police say they believed he was involved in the plot but lacked evidence to prove it.
At the end of the month, Malaysia's then-Prime Minister Najib Razak announces an agreement has been reached to return the body to North Korea. Nine Malaysians stuck in Pyongyang will be free to travel and North Koreans in Kuala Lumpur will be allowed to go home.
In October, the two women go on trial over the murder. They maintain their innocence.
Four men formally accused on a charge sheet of plotting with the women to murder Kim Jong Nam are identified by a police officer as North Koreans who fled Malaysia immediately after the assassination. The women's lawyers insist they are the real masterminds.
