Hello. This doesn't happen often, but tonight on Newsround you've got

Leah and Ore here. You know the drill, guys - we're

live, it's just after five, and all of this is on the way.

Find out why a plan to create more ponds could help these guys.

And forget your laptops and tablets - Nel checks out the original

computer. Before all of that we are starting with a big story that's

been developing in Manchester today. Two female officers have died this

morning after they responded to a call about a borrowingry on a

housing estate in Tameside. The officers weren't carrying weapons

when they were shot. In the last hour they've been named

as PC Nicola Hughes and PC Fiona Bone. A man who handed himself into

the police has been arrested. The Chief Constable of Manchester

Police spoke about what happened a short while ago. Clearly this is

one of the darkest days in the history of Manchester police, if

not the Police Service overall. Because we have lost two deeply

loved and valued colleagues, because they are part of our team,

policing is very much a family. This afternoon the Prime Minister,

David Cameron, described what happened as a "shocking reminder of

the debt we owe to those who put themselves in danger to keep us

safe and secure." We'll keep you updated as we find out more about

that story. But it's important to remember it's extremely rare for

this to happen to officers on duty, but if you are ever upset by

anything you hear in the news, there's help and advice over on the

Newsround website. Next up - British troops serving in

Afghanistan will no longer go on patrol with Afghan forces, because

officers are afraid they'll be attacked. There's been a big rise

in Afghan soldiers and police officers attacking troops who are

part of the international organisation NATO. The BBC's

reporter in the capital city, Kabul, explained to Ricky why this change

of plan is so important. Quentin thank you for joining us on

Newsround. How big a deal is today's announcement by NATO?

is a very big deal. This war has been going on for nearly 11 years.

The enemy is the Taliban. International troops - British

soldiers, Americans and others - have been working with Afghan

soldiers, fighting against the Taliban. But in recent months we've

seen an increasing number of attacks from Afghan soldiers.

They've been killing not the enemy, not the Taliban, but the foreign

soldiers they've been fighting alongside. But it's a tricky

situation isn't it, because British troops do have a responsibility to

work with the Afghan police and if Afghan soldiers out there. Will

this change things now? It is very tricky indeed, because it is vital

that the British soldiers work with the Afghan partners, because there

are hundreds of thousands of Afghan police and Afghan Army here.

Whereas there are only less than 10,000 British sools. So to keep

fighting -- soldiers. So to keep fighting the Taliban they need the

help of Afghans. We spend a lot of time with British soldiers in

Helmand province and around the country. They tell us they don't

fully trust the Afghans they work alongside. They always have to

watch their backs. They always have to be careful. Now whenever Afghan

soldiers or Afghan police are around and have guns there is

always a British soldier who is armed at all times just in case

noif these insider attacks, when the Afghan soldiers turn their

backs on the British soldiers. To other news today. Royal lawyers

have stopped a European magazine from publishing any more private

photos of the Duchess of Cambridge sunbathing without her top on. Kate

and William are still on their tour of South East Asia, but the

magazine has been told to hand over the pictures within 24 hours. If

they don't, they'll have to pay �8,000 a day until they do. Lawyers

for the Royal Family say the photos were a breach of Kate's privacy.

England will soon be embark on the defence of their 2020 World Cup

title today. Kevin Pietersen has been left out of the team squad for

the tour of India. In August he got into trouble for sending rude text

messages about the then England Captain Andrew Strauss to some of

the South African players. Selectors decided on two new

players to replace Strauss and Pietersen.

Charles Babbage never got around to making them, but the Science Museum

in London has got together with a charity to try to build his old

designs. British-born Babbage bane vented

the first computer in the world and he called it the analytical engine.

He also designed the difference engine, which was more like a

sophisticated calculator. The Science Museum had Babbage's

manuscript, so decided to build this engine to see fit would work -

it did! It is a five-tonne machine. It contains over 8,000 parts. It is

effectively a great big calculator. What would it do in Babbage's day?

What was it used for? At this time you had people, mainly women, often

called computers. Babbage's idea was rather than have people doing

this, he could create a machine to do it. This machine wouldn't make

mistakes. But it's the analytical engine that's the real star, and

John Graham Cumming is the man who is going to build it. It is the

first design of a complete security as we would recognise it, with all

the bit, although they are large and mechanical. It has memory. It

has the chip, if you like, which is enormous. And it even has

programmes, apps if you like. would want to build an ancient

computer when there's hundreds of other hi-tech options out there?

You don't have one this big though. This would be the size of small

steam leek motive. The advantage is that you can see how a computer

works. Plans are in materialy stages. Fundraising is several

million it would cost to build Babbage's analytical engine. If

they succeed it will be the only computer of its kind in history.

Next up we're talking about ponds. When they're healthy and well

looked after they're a great place for wildlife. But the charity, Pond

Conservation, is warning that 80% of them in England and Wales are

badly polluted. They want to tackle the problem by undertaking a

massive pond-building mission on a scale that's never been seen in the

UK. I went to a pond to find out Dragonflies, frogs and newts.

You'll find them in ponds around the UK. But decades of not being

looked after means their habitat is under threat. The UK's ponds have a

greater range of creatures per square metre than any other habitat,

but half the country's ponds have disappeared over the past century.

Of those that remain, more than two thirds are completed. Harmful

chemicals and fertilisers and pesticides on farm which is wash

into ponds when it rains are partly to blame. The problem is ponds

can't been cleaned up. When the damage is done it is virtually

impossible to get them back to the standard needed by sensitive fresh

water plants and animals to survive. The Million Ponds Project is the

largest ever pond-creation programme in the UK. Over the next

seven years the plan is to create 30,000 new ponds in England and

Wales. Why sit so important that we act at this moment? It is really

important we create these 30,000 ponds over the next seven years.

We've identified the species at greatest risk of even extinction in

Britain. Around 10% of those species are reliant on fresh water

pond habitat. If we don't take action now we could lose those

species altogether. In 50 years it is hoped there'll be 1 million

clean fresh water ponds in the UK that. Can only be a good thing for

these guys. Man City kick off their Champions

League campaign tonight with a toughy against Real Madrid. Roberto

Mancini's boys will be hoping to go one better than last year when they
