North Korea has held a military parade attended by leader Kim Jong-un, a day before the opening of the Winter Olympics in the South.

The North often boasts of its parades but reports of this surfaced afterwards with TV only airing delayed footage.

This event is usually held in April and moving it had been seen as a setback to the warming of ties over the Olympics.

But the South announced on Thursday its president would meet the North’s Olympics delegation on Saturday.

Moon Jae-in will have lunch with the 22-strong team, which will include the North’s ceremonial head of state, Kim Yong-nam, and Kim Yo-jong, the influential sister of Kim Jong-un who will become the first member of the ruling dynasty to visit the South. Both were at the parade.

What do we know about the parade?

Early on Thursday state TV began showing patriotic films in what appeared to be a prelude to a live broadcast.

But delayed and unscheduled footage of the event only appeared on TV in the North at 17:00 local time (08:30 GMT).

The parade was reportedly smaller than recent years and the footage showed Kim Jong-un inspecting troops, alongside his wife Ri Sol-ju. There was the traditional goose-steeping and a show of heavy weapons.

Mr Kim said the North had become a “world-class military power”.

The annual parade, which this year marks the 70th anniversary of the foundation of the Korean People’s Army, is normally held in April and this was the first time in 40 years it had been given a February date.

Such parades are often given a much higher profile. In 2017, North Korea aired a live broadcast of its military parade on state television. Foreign journalists were invited to cover the event.

South Korean government officials said last month that some 13,000 troops and 200 pieces of equipment had been spotted near an airport in Pyongyang in what appeared to be a rehearsal for the parade.

What was on show?

While much of the parade was standard fare, it was the event’s climax with the appearance of North Korea’s missile force that drew the greatest attention.

The stars of the show were four Hwasong-15 ballistic missiles on their nine-axled TEL vehicles (Transport Elevator Launcher).

The Hwasong-15 made its maiden flight in November last year and has a claimed range of more than 13,000km (8,000 miles), which would theoretically put Washington DC in range.

It’s the first time that multiple examples of the type have been seen together.

Also on display were several Hwasong-14 missiles (designated KN-20 by the US) on extended truck mounts, as well as Hwasong-12 (KN-17) and Pukguksong-2 (KN-15) intermediate range missiles.

Most notable by their absence were any additional TEL vehicles, possibly meaning the North is still struggling to overcome a shortage.

Some observers also saw possible clones or copies of Russian 9K720 Iskander short-range ballistic missiles.

Why hold the parade now?

The North had insisted on the event, despite criticism from the US and others about its timing – a day before the opening ceremony of the Winter Olympics, which run from 9 to 25 February in the mountain town of Pyeongchang.
