North Korea's leader Kim Jong-un has appeared with his young daughter in public for the first time, confirming long-rumoured reports of her existence.

The girl, believed to be named Kim Chu-ae, joined him at an inspection of a major intercontinental ballistic missile launch on Friday.

The pair stood hand-in-hand during the test, which was condemned by the US. Mr Kim leads one of the world's most secretive states, and very little is known about his personal life.

Photos were published by North Korea's state news agency KCNA, showing the two holding hands while they chat, speaking with officials, inspecting missiles and watching the launch from a viewing deck.

The revelation of Kim Jong Un's daughter has interested North Korea analysts far more than news it has successfully launched its most powerful intercontinental ballistic missile

Unveiling her at such a significant launch suggests she will one day play a role in developing the country's weapons.

Recently Mr Kim announced that he would not, under any circumstance, be giving up his nuclear weapons. This is a way of showing the world his nukes are here to stay, through to the next generation.
