US President Donald Trump and North Korean leader Kim Jong-un sign an agreement in Singapore
North Korea "commits to work towards the complete denuclearisation of the Korean peninsula" but analysts say it has not made specific commitments
Mr Trump later defends what he has achieved and stuns observers by saying the US will stop war games with South Korea that infuriate the North
He says Mr Kim agreed to destroy a "major missile engine testing site" and that sanctions won't be lifted until progress is made on denuclearisation
The summit is the first time a sitting US president has ever met a North Korean leader

We don’t know how well prepared Kim Jong-un is for the summit, but the assumption is: very. Donald Trump? The US president went on record as saying he doesn’t have to do his homework. "I don't think I have to prepare very much," he told reporters just before leaving for Singapore. "It's about attitude. It's about willingness to get things done." Today will show how this works out.
The very fact the meeting is taking place marks a dramatic shift in relations between the two leaders, who last year traded insults and threats of war.
Here's our full story on the events in Singapore so far, and what we expect from today.
There were some extraordinary scenes in Singapore last night as Mr Kim took a tour downtown. Some in the crowd were shouting "Mr Kim, we love you".
Unusually, Mr Kim's tour was also reported on state media back home. It almost never reports on the leader's activities in real time, so North Koreans often don't get the (heavily censored) information for days.
North Korean defectors, meanwhile, have been reminding the BBC about conditions for those who do not toe the line back home.
“Mr Kim… we love you!”
President Donald Trump is up early and has tweeted confidently in the past hour:

So here's something pretty much unthinkable just a few weeks ago: a selfie with Kim Jong-un, smiling into the camera. The guy who took the picture and posted it on Twitter? That's Vivian Balakrishnan, Singapore's minister for foreign affairs. He was out for an evening about town with the North Korean leader. The post drew a lot of criticism online, but it shows that the normalisation of Kim from brutal isolationist leader to statesman is in full swing.
We're here in Singapore, where the meeting will take place. The two leaders are staying separately at hotels a few miles down the road. We’ll be bringing you minute-by-minute coverage, observations from our BBC colleagues on the ground here as well as in China, South Korea, the US and around the world. And of course comment from Korea experts and our colleagues in BBC News Korean.

Why historic? Well this is the first time a sitting US president had met a leader of North Korea - two previous firm enemies. It’s happening after a surreal roller coaster ride of diplomatic back and forths, and a LOT of uncertainties. The two are discussing a crisis that, only a year ago, saw them threatening each other with nuclear annihilation.
Welcome to the BBC’s live coverage of a historic day. The meeting between US President Donald Trump and North Korea's leader Kim Jong-un is upon us. It’s 06.30 local time in Singapore - they will meet in a few hours' time. We’re going to be with you all the way.
