and why this song is breaking more records.

First to the big argument between the United States

of America and North Korea, a country in the east of Asia.

And, to careers, warships, missiles and threats. What is going on and is

it as scary as it sounds? Let's start with the two careers. One

country is called North Korea and the other, South Korea. They were

split into Mac after World War II fought a war with each other shortly

after that and haven't gotten along since. And now the two men? One is

the leader of North career. He is Kim Jong Un and he runs the country

just like his dad and grandad before him. The other is Donald Trump.

President of the US app. A country which has supported South Korea for

along time. North Korea is a country that has cut itself off from the

rest of the world. Lots of things are run in secret there and Kim has

huge control over people's lives. He has also been trying to build

nuclear missiles, powerful bombs that can cause devastating damage,

that one day might be able to hit the USA. President Trump wants to

stop this happening and he's given a warning. North Korea is best not

make any more threats to the United States. They will be met with fire

and fury like the world has never seen. In return, North Korea has

threatened US military bases in the area. So all of this is pretty

worrying too many people around the world. But there have been many

arguments between the USA and North Korea in the past. And although

they've never been friends, things have been worked out to stop a war.

Everyone is hoping that will be the case this time as well.

Roared on by the crowd, he qualified, booking

I wish to thank the IAAF for giving me another chance.

I just want to thank this crowd - it's so amazing.

And Mo Farah will be going for gold again on Saturday,

after he qualified for the final of the 5,000 metres last night.

He'll be joined by fellow Brit Andy Butchart,

after he qualified as a fastest loser from the second heat.

Mo says he's worked hard for what he's achieved,

and encourages people to do the same.

You can't dream of something unless you do something about it. And I've

been given a chance in life and I work for hard for it and I achieve

what I have to do from hard work and keep grafting. To all the

youngsters, you can be like me. Stargazers around the world

are getting ready to enjoy the best bits of the spectacular
