North Korea revealed leader Kim Jong-un's daughter for the first time Saturday in photos showing them attending the test-firing of an intercontinental ballistic missile (ICBM) the previous day.

The North's state media reported that Kim inspected the launch of a Hwasong-17, the country's largest ballistic missile, at Pyongyang International Airport on Friday.

He was present at the scene "together with his beloved daughter and wife," the North's official Korean Central News Agency said.

Photos released by the news agency showed his daughter in a white winter jacket and black pants standing and walking together with Kim in front of the missile that sat on a launch truck.

The daughter apparently in her tweens was also seen along with her mother, Ri Sol-ju, watching her father as he instructed military officials.

It marked her first official appearance in state media.
