Kim Jong-nam, the older half-brother of North Korean leader Kim Jong-un, was killed in a Malaysian airport Monday after he was sprayed in the face with an unknown liquid, police said Tuesday. He then died on the way to the hospital after being assisted by workers at the airport.

Two women were responsible for Kim's death, according to a South Korean source.

Malaysia's Criminal Investigation Department (CID) chief Mohmad Salleh earlier told Channel NewsAsia that travel documents found on the man indicated he was Kim Jong Nam.

Recently he was believed to have been living in Macau, Singapore and Malaysia.

South Korean media reports meanwhile said Jong-Nam had travelled using a fake passport under the name of Kim Chol.

Jong-Nam, known as an advocate of reform in the North, once told a Japanese newspaper that he opposed his country's dynastic system of power.

A North Korean man in his 40s died suddenly at Kuala Lumpur International Airport, an officer from the police division overseeing the airport told The Nikkei.

Interestingly, his half-brother, the current North Korea leader, was also educated in Switzerland but developed no such opinions.

Kim Jong Nam had a son named Kim Han Sol, who used to study in Bosnia and later France.

South Korean intelligence agencies were not immediately able to confirm the report, according to The New York Times.

Kim Jong-nam and Kim Jong-un are both sons of former North Korean leader Kim Jong-il, who died in late 2011, but they had different mothers. The reason? Despite his outspoken opposition to North Korea's oppressive regime, he was probably Kim Jong-Il's oldest son - making him the true heir to the North Korean throne. The men deliberated on a response in a dining room at Trump's Mar-a-Lago club, in full view of other diners.

The South's MOU said the Malaysian police hadn't revealed the cause of death of Kim Jong Nam as well as the circumstances around the incident. TV Chosun said that the North Korean leader appeared to have sent agents to assassinate his eldest sibling, considering him a potential threat to his rule. Since the beginning of previous year, North Korea has conducted two nuclear tests and more than two dozen missile tests, the most recent last weekend when an intermediate range missile flew about 300 miles from a launch site northwest of Pyongyang.

Kim went into hiding in Malaysia after the execution of his uncle, Jang Song-thaek, back in December 2013.

Indeed, Thae Yong-ho, the highest profile North Korean defector in recent history, hinted recently that Kim Jong-un's leadership was in trouble, saying, "The traditional structures of the North Korean system are crumbling".
