Assassination of Kim Jong-nam
Documents violence — written to inform, not to shock.

On 13 February 2017, Kim Jong-nam, the older half-brother of North Korean leader Kim Jong Un, died at Kuala Lumpur International Airport in Malaysia after being attacked with VX nerve agent. Kim had lived abroad since his exile from North Korea in 2003 and was traveling under the pseudonym "Kim Chol." He arrived at KLIA2's departure hall around 9:00 a.m. to catch a 10:50 a.m. AirAsia flight to Macau, after having visited the resort island of Langkawi. Two women approached him and applied separate components of VX to his face and hands, which combined to form the lethal nerve agent. Kim reported to an airport receptionist that he had been grabbed from behind and had liquid splashed on his face. He was treated at an airport clinic, given atropine, adrenaline and tracheal intubation, but died roughly 15 to 20 minutes after the attack while being transported to Putrajaya Hospital.
Malaysian police arrested Đoàn Thị Hương, a Vietnamese national, on 15 February, and Siti Aisyah, an Indonesian national, on 16 February, identifying both through CCTV footage. Both women were charged with murder, which carried a mandatory death sentence under Malaysian law. Both said they believed they were participating in a prank for a hidden-camera video and had been promised payment they never received. According to their lawyers, they had been separately recruited and handled by North Korean men posing as being from Japan and China, and had rehearsed similar "pranks" on other unsuspecting people on multiple prior occasions. Malaysian police also named several North Korean suspects, including four men who left Malaysia shortly after the attack and reached Pyongyang, and others who took refuge in the North Korean embassy in Kuala Lumpur and were later released without charge after being interviewed and cleared. One detained North Korean man, Ri Jong-chol, was released and deported due to lack of evidence.
An autopsy, conducted despite North Korean objections, found VX degradation products on Kim's body and on the two women's clothing, and a pathologist testified there was no evidence of the heart attack North Korea claimed had caused his death. The murder trial of Aisyah and Hương began in October 2017 at the High Court in Shah Alam. Testimony covered forensic toxicology, CCTV evidence, and the women's history of performing similar "prank" videos. In March 2019, Malaysia's attorney general dropped the murder charge against Aisyah following a request from the Indonesian government, and she was released. Malaysian prosecutors initially declined similar treatment for Hương, prompting criticism from lawyers and Vietnamese officials that this was discriminatory. On 1 April 2019, the murder charge against Hương was also dropped, and she pleaded guilty to a lesser charge of voluntarily causing hurt by dangerous weapons or means, receiving a sentence of three years and four months, reduced by one-third; she was released on 3 May 2019.
The assassination triggered a diplomatic dispute between Malaysia and North Korea, including expulsion of ambassadors, travel restrictions on each other's citizens, and North Korea's rejection of Malaysian findings. The United States later cited the assassination as one reason for relisting North Korea as a state sponsor of terrorism and imposed sanctions over North Korea's use of VX nerve agent.
