North Korea says it will begin dismantling its nuclear test site in less than two weeks in a ceremony attended by foreign journalists.
Pyongyang said it was taking "technical measures" to carry out the process between 23-25 May, North Korean state news agency KCNA reported on Saturday.

Scientists previously said the site may have partially collapsed in September.

The move is due to take place three weeks before US President Donald Trump meets North Korean leader Kim Jong-un.

What will the ceremony include?


The dismantling of the Punggye-ri site, the exact date of which will depend on weather conditions, will involve the collapsing of all tunnels using explosives and the removal of all observation facilities, research buildings and security posts.

Journalists from South Korea, China, the US, the UK and Russia will be asked to attend to witness the event.

In a statement on Saturday, North Korea said the intention was to allow "not only the local press but also journalists of other countries to conduct on-the-spot coverage in order to show in a transparent manner the dismantlement of the northern nuclear test ground".

What do we know about the test site?


Situated in mountainous terrain in the north-east, the Punggye-ri site is thought to be the North's main nuclear facility.

Nuclear tests have taken place in a system of tunnels dug below Mount Mantap, near the Punggye-ri site.

Six nuclear tests have been carried out there since 2006.

After the most recent test, which took place in September 2017, a series of aftershocks hit the site, which seismologists believe collapsed part of the mountain's interior.

How important is the Trump-Kim meeting?


Mr Trump and Mr Kim are due to meet in Singapore on 12 June. It will be the first time a sitting US president has ever met a North Korean leader.

The key issue expected to be discussed is North Korea's nuclear weapons programme, over which the two leaders furiously sparred in 2017.

The US wants Pyongyang to give up its weapons programme completely and irreversibly.

Confirmation of the meeting between the two men came after landmark talks between North and South Korea.

Mr Trump announced the date and place of the summit earlier this week, hours after he welcomed home three US detainees released from North Korea.

"We will both try to make it a very special moment for World Peace!" he tweeted.

Is North Korea opening up?


There is a "sense of optimism" among North Korea's leaders, the head of the UN's World Food Programme (WFP) said on Saturday after enjoying what he said was unprecedented access to the country.

David Beasley spent two days in the capital, Pyongyang, and two outside it, accompanied by government minders.

He said the country was working hard to meet nutritional standards, and hunger was not as high as in the 1990s.

Mr Beasley's visit, from 8-11 May, included trips to WFP-funded projects - a children's nursery in South Hwanghae province and a fortified biscuit factory in North North Pyongyan province.

"I didn't see starvation like you had in the famine back in the 1990s, that's the good news. But is there a hunger issue, is there under-nutrition? There's no question about it," he told the BBC.

"There is a sense of turning a new page in history," he said.
