STORY: North Korea test-fired a Hwasong-17 intercontinental ballistic missile (ICBM) on Friday, state news agency KCNA reported on Saturday.
The biggest surprise, however, was the presence of Kim's daughter, whose existence had never been publicly confirmed before.
KCNA did not name the girl, who is seen in photographs in a white puffy coat holding hands with her father as they look at the massive missile.
Kim is believed to have as many as three children, two girls and a boy, experts said. Some observers believed one of those children was seen in footage of celebrations for a national holiday in September.
North Korea has never announced who would follow Kim in the event he is incapacitated, and with few details known about his young children, analysts had speculated that his sister and loyalists could form a regency until a successor is old enough to take over.
