Malaysia says cause of death still unknown in killing of north korean

You're referring to the mysterious death of Kim Jong Nam, the half-brother of North Korean leader Kim Jong Un, who was killed at Kuala Lumpur International Airport in Malaysia in February 2017.

According to reports, Kim Jong Nam was attacked with a deadly nerve agent, VX, at the airport's departure gate. Two women, one from Vietnam and one from Indonesia, were arrested and charged with his murder. However, the investigation has been ongoing, and the cause of death is still unknown.

Malaysian authorities have said that they are still waiting for the results of further tests to determine the exact cause of Kim Jong Nam's death. The country's health minister, Dr. Subramaniam Sathasivam, has stated that the autopsy report showed that Kim Jong Nam died from "acute VX poisoning," but the exact mechanism of the poisoning is still unclear.

The case has been shrouded in mystery, with many questions remaining unanswered. The two women accused of the murder have denied any involvement, and North Korea has denied any involvement in the killing. The case has also raised concerns about the use of chemical weapons and the lack of transparency in the investigation.

It's worth noting that the investigation has been complicated by the fact that North Korea has refused to cooperate with Malaysian authorities, and the country has been accused of trying to cover up its involvement in the killing. The case remains a major diplomatic incident between Malaysia and North Korea, and it's unclear when or if the truth about Kim Jong Nam's death will be revealed.
