Malaysian police officials were quoted in news reports as saying that the 45-year-old Kim was sprayed with a chemical spray at a Kuala Lumpur airport and died while being taken to a hospital.
Ri's daughter-in-law, however, was excluded from the family purge mainly because her father Han is now in a high-ranking position at the foreign ministry and her mother was from the family of Lim Chun-chu, one of North Korea's independence fighters, Thae was quoted as saying.
Jong-Nam, who was travelling alone, had at 9am told airport staff at a reception desk that he felt "dizzy" after an unknown person had swabbed his face with an unknown object.

Mr Kim was known to lead a life of luxury outside his country. Ko and Kim Jong Il had another son, Kim Jong Chol, who was seen at an Eric Clapton concert in London in 2015.
Kim Jong Nam was the most public of all of Kim Jong Il's sons before Kim Jong Un took power, though most remember him for the scandalous headlines he made.
If reports are true, this could be the most significant killing of a member of North Korea's ruling family since the death of Jang Song Thaek in 2013. "We do not know his identity", he said.
The North Koreans have been implicated in at least one other poison needle attack, in 2011, when a South Korean pastor and activist died mysteriously in China.

For good measure, the president added: "I don't ever want to call a court biased and we haven't had a decision yet". Trump insisted Blumenthal was mischaracterizing Gorsuch's words, though a Gorsuch spokesman confirmed them.
Kim Jong-nam survived another suspected assassination attempt in 2011 in Macau.
South Korea's presidential office said it had no plan to convene a National Security Council session as there is no unusual movement in North Korea. He is believed to have been born May 10, 1971, although birthdays are always unclear for senior North Koreans, Gause said.
Kim Jong-Un has been trying to strengthen his grip on power in the face of growing global pressure over his country´s nuclear and missile programmes.
"The power elite that have ruled the country will continue to be in control", wrote Kim Jong-nam in an email. But it's widely believed Kim Jong-Un saw his older half-brother as a threat to the regime. Her roots in Japan, Korea's former colonial master, had negative implications in the North and were kept hidden from the ordinary people.
Fadzil said an ambulance picked up Jong-Nam from the airport. "He was originally going to succeed Kim Jong Il".
Kim was a frequent traveler to China but had not defected from the North Korean government.
"I would say maybe this smart, overweight playboy from Macau has the highest chances of physical survival of all the Kim Jong Il children", Professor Andrei Lankov of Kookmin University told the outlet in 2012.
