19/06/2017 Newsround

Good morning, Jenny here with your Monday Newsround.

First, there's been a serious incident in London overnight.

Shortly after midnight, a van drove into a crowd

of worshippers coming out of a mosque in Finsbury Park,

in north-east London.

Police are making the area safe, and have closed roads.

Several people have been taken to hospital, and one

person has sadly died.

One man has been arrested.

As we find out more about what happened,

you'll be able to get updates at Newsround online,

and don't forget if you're upset by this story,

or by anything in the news, there's loads of help

and advice there too.

Now, the Tour de France starts in just under two weeks.

It's one of the toughest bike races in the world,

and includes cycling up some of the biggest mountains in France.

But how do you go from riding your bike in the park, to taking on some

of cycling's biggest challenges?

Whitney went to meet a brother and sister who've done just that.

Alfie and Saskia have cycled 300 miles from London to Paris.

Alfie's climbed Mont Ventoux, the hardest mountain

of the Tour de France.

And he's also got to the top of Col du Tourmalet -

that's 2115 metres high.

How did you get into cycling and become so good at it?

My dad did London to Paris in a day.

It just made me want to do something amazing just like him.

I'm not actually that good, it's just I'm very determined

to complete what I've started.

You can see I'm not the best at this.

What advice would you give to people who want to be as great as you?

Try every type of cycling and if you don't like one type,

try the other until you can find what you like doing.

It's just good to keep trying.

Even if you fall over a few times, well, cycling's difficult and you'll

get used to it eventually.

Tour de France is coming up.

Alfie, you've gone up some of the toughest mountains

that are in the race.

How did you get good enough to do that?

It was really, really hard.

I thought about giving up at parts of it but when I was at the top

I just knew that it was there and I had to keep on going

because I was going to do it.

And are you both looking forward to Tour de France?

With Alfie having gone up the mountains, it's kind of exciting

watching the ones he's gone up, like, "Huh, my brother's

done that already!"

I have to say, you guys have given me top tips,

you're making me feel more confident and motivated.

Shall we go for a ride?

Yeah, of course.

I hope that I don't fall.

Fetch, sit and roll over - they're all things that

you would teach a dog to do.

But what if your pooch doesn't understand what you're saying?

Here's Ricky.

Stay...

Stay.

Meet Caleb, a four-year-old rescue dog like any other,

apart from one thing - he doesn't understand English.

Drop it...

Drop it.

And although he's a German shepherd, German isn't the language

he understands, it's Polish.

Staff here only figured out what the answer was when a man

who spoke Polish came to take one of the other dogs home.

As soon as he heard the language, Caleb's ears pricked

up, and they realised he understood every command.

He was sitting down, he was lying down, he was giving them a paw,

he was giving the ball back to us, doing all sorts, and whenever

we tried we just got absolutely nothing, he was all over the place.

So now they've started learning Polish.

"Paw" is "lapa".

And Caleb has started to understand English,

which will make finding him a new home much

easier in the future.

Maybe even with a family that speaks both languages.

Sport now, and British tennis number one Jo Konta lost her first

grass court final on home soil, as she was beaten at

the Nottingham Open by Donna Vekic.

The competition was one of Jo Konta's warm-ups before

Wimbledon, which starts in July.

Next up, a trip to the hospital can make some people feel a bit nervous.

Well now a project is hoping to help kids who aren't that keen

on a visit to the doctors.

Welcome to teddy bear hospital.

It's where children here in Croatia get to experience what it's

like to visit a hospital or be seen by a doctor.

It's normal to feel a bit nervous before going for a checkup,

that's why this special project was set up.

It involves a bit of role-play.

Medical students are the doctors and children pretend to be

the parents of their toys, who are the poorly patients.

TRANSLATION: By playing here, they get the feeling it's some

kind of game when they visit the doctor, and that's great.

The teddy bear hospital project started 20 years ago in Sweden,

and now it's happening all over the world.

TRANSLATION: This is also good for student doctors,

so they know what to expect in the real world.

You get a better idea about what it's like,

better than studying from books.

The whole point is to make children feel relaxed when it

comes to the real thing, and these kids look pretty happy.

Thanks, Ricky.

Meet the latest additions to this Siberian tiger family.

These four cubs are just a month old and were born in a wildlife

sanctuary in southwest China.

At the moment, the four cubs haven't been given names,

so staff can only tell them apart by the different

stripes on their tails.

That's all from the team for now.

Newsround's back at 4.20pm.

Don't forget to head online for the rest of the day's stories.

Goodbye.

There's an Easter egg hunt in Little Roy next

and Little Roy gets accused of cheating.

A bit like when you lot said that I'd cheated

at the CBBC HQ treasure hunt. It is nothing like that.

You DID cheat on the CBBC HQ treasure hunt.

What are you on about? Allegedly!
