South Korea Probes Kim Jong Un Family and Daughter’s Succession
South Korea’s spy agency is studying Kim Jong Un’s family.
It is trying to find out whether he has a son.
One report describes the possible child as an older brother of Kim Ju Ae.
Another assessment says Kim Ju Ae has a younger sibling, but does not know the sibling’s gender.
This means the reports do not agree about the sibling’s age or sex.
The agency still believes Kim Ju Ae is being prepared to lead North Korea.
She is a teenage girl who often appears in public with her father.
Even if Kim has a son, the agency says he is not currently likely to take over.
The investigation shows that important details about Kim’s family remain uncertain.
South Korea’s National Intelligence Service is investigating whether Kim Jong Un has an elder son.
Another agency assessment says Kim Ju Ae has a younger sibling whose gender is unknown.
The reports differ on whether the possible sibling is older or younger than Kim Ju Ae.
The agency says Kim Ju Ae is being groomed as North Korea’s successor.
Even if a son exists, the agency says he is not currently positioned to succeed Kim Jong Un.
