According to South Korea, she has a younger sibling, while daughter Ju-Ae is believed to be around 13 years old. It has previously been reported that Kim Jong-Un has a total of three children, but Ju-Ae - who is believed to be the middle child - is the only one who has been seen in public.
South Korea's security service now claims to have information confirming that Ju-Ae has a younger sibling of "unknown gender." At the same time, it notes that Ju-Ae is being groomed to become her father's successor, something that has also been previously speculated.
Reports that Ju-Ae has an older brother are also being investigated.
"But even if he exists, he is not relevant as a successor," the security service writes.
