North Korea's state-run TV has released video of the country's test-firing on Friday of a new Hwasong-17 intercontinental ballistic missile.

Korean Central TV broadcast the footage from 3 p.m. on Saturday, showing the missile's launch from an international airport near North Korea's capital, Pyongyang.

The video shows the country's largest ballistic missile being carried out of a hangar on board a 22-wheeled mobile launch pad.

The footage covers the launch from various angles. It includes the missile ascending, spewing flames through its four nozzles and then appearing only as a small bright dot.

A camera attached to the missile captured images of Earth's surface fading in the distance.

State-run TV also aired photos of North Korea's leader Kim Jong Un and his daughter walking hand-in-hand to observe the launch onsite.

It is the first time North Korea has released photos of one of Kim's children.
