Hi, I'm Hayley, coming

up on Newsround:

A spy mystery involving

Russia and the UK.

A Chinese clay army

on display in Liverpool

And...

The hostel where you can

pretend to be an astronaut!

Officials in Russia are being asked

to explain what they know

about happened to a former spy who's

been hurt here in the UK.

Ayshah has more on this.

This is Sergei Skripal,

he's from Russia and was jailed

there more than ten years

ago for being a spy,

but he was released and now lives

here in the UK in Salisbury.

Just over a week ago,

he was found on a bench

in the city centre along

with his 33-year-old daughter Yulia.

They were both very poorly.

It's thought they'd been

poisoned deliberately.

It's also thought a policeman

was affected by the poison

after going to help find

out what happened.

He's in hospital too.

Skripal spied on Russia,

where he's from, for Great Britain

and that's why many people think

he's been hurt.

The British Prime Minister

says the poison used

to attack him was made in Russia.

The Government has concluded

that it is highly likely that Russia

was responsible for the act

against Sergei and Yulia Skripal.

But a member of the Russian

government says that's rubbish.

Theresa May says Russia has

until midnight to explain

properly what happened.

Skripal and his daughter had been

to a restaurant in a pub that day.

People who'd also been there have

been told to wash the clothes

they were wearing and any items

they had with them.

Health experts say the risk

to the public is low though.

Emergency services and army experts

are investigating and helping

to keep people safe.

OK history fans,

stick around for this,

we're heading to Liverpool to see

an ancient underground army

that's been kept hidden

for thousands of years.

Martin s got this.

This is the Terracotta Army.

It was buried deep underground

secretly guarding the tomb

of China's first Emperor

for more than 2,000 years,

until it was discovered by accident

as farmers dug the land.

The tomb belonged to

Emperior Qin Shi Huang,

the founder of the Chinese empire,

who had many enemies.

He believed that these full-size

clay soldiers would protect him

in the next life after he died.

Now, they've been carefully brought

back to the surface and repaired

for everyone to see.

But you don't have to go all the way

to China to see them,

some of them are right

here in Liverpool.

So these kids have been

to check them out.

How long did it take to make

the terracotta warriors?

We don't know exactly

how long it took

to make one warrior

but, as you can see,

they are so detailed

and elaborate, I imagine

it would have taken quite some

time to make each one.

Each part of the body

was made separately,

so the legs and feet were made,

and they were solid clay.

Because they're so heavy, the base

of them had to be quite steady.

Who were the strongest warriors?

The warriors are all soldiers

who were ready to fight in battle,

but in another pit nearby

were figures that the emperor had

made to entertain him

in the afterlife, and in that pit

were acrobats and strongmen,

and the strongmen figures

had really big muscles,

so I imagine they were

meant to be very strong.

So, what do they make of the army?

I'm so amazed how big

the terracotta warriors are.

I like how they look

and they've got armour on,

they look really detailed.

When I imagined what they would look

like, I wasn't expecting them

to be a really big size.

I think it's actually really

impressive that they came from China

all the way to Liverpool and that

they're still in really

good shape and condition.

Thanks, guys.

And if you've ever wanted

to experience staying in space

but don't fancy the long rocket

flight, then check out

the 'Subspace' hostel in Croatia.

Croatia's first space capsule hotel

has just won an award for the best

hostel in Eastern Europe.

Guests get to feel like they're

on board a spaceship

with all the gadgets and gizmos

and of course the

cramped living space.

The tiny bedrooms are called

capsules, they're only two metres

long and are 1.2 metres

wide and high.

That's about the size

of your school desk,

but they manage to squeeze in a bed,

a monitor, a safe

and a mirror there.

There's no windows or natural light,

but you can see the stars

and planets painted on your ceiling.

So you can imagine you're flying

through space when in fact you've

not moved and cannot move further

than a few steps.
