Five years later, Kim Jong Nam was attacked on Monday in the second terminal of Kuala Lumpur International Airport in Malaysia, which is reserved for low-priced carriers.
According to two senior Malaysian government officials, who spoke on condition of anonymity because the case involves sensitive diplomacy, the elder Kim died en route to a hospital on Monday after suddenly falling ill at the budget terminal of Kuala Lumpur International Airport. Malaysians and North Koreans can visit each other's country without visas.
One of the women touched Kim's face with a cloth that contained an unidentified liquid before both departed in separate directions, police said.
Lawmakers from South Korea, bitter enemy of the North, said that their intelligence agencies believe this was a false alias and that the man was in fact the half-brother of North Korea's dictator.
Kim Jong Un had about 50 officials executed in 2014 on charges ranging from graft to watching South Korean soap operas.
There is also a dividing view of whether the apparent assassination can "be understood as a display of Kim Jong-un's tightening grip on power or conversely, as symbolic of the young leader's struggle for stability", says Dr Bell."It is also possible that China is looking for an alternative North Korean leader and could have thrown their support behind another member of the Kim family".
Inspector-General of Police Khalid Abu Bakar said yesterday the North Korean tried to seek help at the customer service counter at KL International Airport 2.
News of the murder came two days after Kim Jong Un test-fired a ballistic missile as part of efforts to develop North Korea's nuclear-weapons capability.
This took place despite North Korean objections about an autopsy taking place.
In 2012 he published the book: "My Father, Kim Jong Il, and I - Kim Jong Nam's Confessions", based on interviews and about 150 emails he exchanged with Kim Jong Nam for seven years. There is speculation that Beijing hoped to install him as North Korea's leader should crisis erupt in the Korean Peninsula.
The estranged half-brother of North Korean leader Kim Jong Un has been killed in Malaysia, according to South Korean security sources.
Who was Kim Jong Nam?
Kim Jong-nam may have invited his half-brother's ire by criticizing him publicly.
My Father, Kim Jong-Il and Me (2012) is not available on Amazon or anywhere else in English. She has a position in a propaganda and agitation department and is known as Kim Jong Un's gatekeeper, Gause said.
