0:00:08 > 0:00:10I'm Ricky and you're with Newsround.
0:00:10 > 0:00:13On the way.
0:00:13 > 0:00:17Who's the latest star to join Strictly?
0:00:17 > 0:00:27And watch this mascot's epic fail!
0:00:29 > 0:00:32First to the big argument between the United States
0:00:32 > 0:00:35of America and North Korea, a country in the east of Asia.
0:00:35 > 0:00:37So what do we know?
0:00:37 > 0:00:41Here's Whitney:
0:00:41 > 0:00:42Two men.
0:00:42 > 0:00:43Two Koreas.
0:00:43 > 0:00:46Warships, missiles and threats.
0:00:46 > 0:00:49What is going on, and is it as scary as it sounds?
0:00:49 > 0:00:52Let's start with the two Koreas.
0:00:52 > 0:00:57One country is called North Korea, and the other South Korea.
0:00:57 > 0:01:01They were split in two after World War II, fought a war
0:01:01 > 0:01:08with each other shortly after that and haven't got along since.
0:01:08 > 0:01:11And now the two men.
0:01:11 > 0:01:15One is the leader of North Korea - he's Kim Jong Un, and he runs
0:01:15 > 0:01:18the country just like his dad and grandad before him.
0:01:18 > 0:01:22The other is Donald Trump, President of the USA -
0:01:22 > 0:01:26a country which has supported South Korea for a long time.
0:01:26 > 0:01:31North Korea is a country that has cut itself off
0:01:31 > 0:01:33from the rest of the world.
0:01:33 > 0:01:36Lots of things are run in secret there, and Kim has huge control
0:01:36 > 0:01:38over people's lives.
0:01:38 > 0:01:41He's also been trying to build nuclear missiles -
0:01:41 > 0:01:45powerful bombs that can cause devastating damage -
0:01:45 > 0:01:49that one day might be able to hit the USA.
0:01:49 > 0:01:53President Trump wants to stop this happening and he's given a warning.
0:01:53 > 0:01:59North Korea best not make any more threats to the United States -
0:01:59 > 0:02:07they will be met with fire and fury like the world has never seen.
0:02:07 > 0:02:11In return, North Korea has threatened US military
0:02:11 > 0:02:14bases in the area.
0:02:14 > 0:02:18So all of this is pretty worrying to many people around the world.
0:02:18 > 0:02:21But there have been many arguments between the USA
0:02:21 > 0:02:25and North Korea in the past - and although they've never been
0:02:25 > 0:02:28friends, things have been worked out to stop a war.
0:02:28 > 0:02:35Everyone's hoping that will be the case this time as well.
0:02:35 > 0:02:37Meet Mark Beaumont.
0:02:37 > 0:02:39He's on a mammoth mission to cycle around the world,

0:03:21 > 0:03:25it has been broken by other riders, and he now stands at 123 days.
0:03:25 > 0:03:28This time, he is not trying to break the existing record
0:03:28 > 0:03:30by a couple of days, that would be far too easy,
0:03:30 > 0:03:32he is aiming to do it in just 80.
0:03:32 > 0:03:36And it has not been easy.
0:03:36 > 0:03:39The first day, putting miles in the bank feels great.
