>> stark warning from the organization in the government for the economy. the euro zone is falling into a severe recession. the former army chief tells the country sri lanka is going to cooperate in a war crimes investigation. and the first commercial flight taking cargo to the international space station. welcome to "bbc world news." would you volunteer to be a human guinea anything? we talk to people who have agreed to take part in drugs trials.

>> fresh warning that the crisis in the euro zone is the biggest threat to the recovery of the world economy. opportunities must now be taken to tackle the problem. it comes to us after youth unemployment, particularly in europe remains at crisisal levels with no sign of improvement for at least another four years. the split between europe's leaders on whether to cut or widen debt. >> alexis, the greek ultra left leader is riding a wave of popularity at home. but here in paris, he's been welcomed this time only by like minded politicians. the french president is now a socialist, the man next to him on stage is another socialist. and then there's the crowd.

>> your presence gives us strength for the fight we fight, because we are fighting for everyone in europe. we are going to win altogether. >> despite being anti-austerity is not anti-euro. he play be in the elections, but by then they will have the program in place. one reason they met on monday. >> in these critical times we indeed need close cooperation. i'm very optimistic that we will accomplish that like we always used to in the past. >> but for how long can that optimism last when the u.n. labor operation is warning of unemployment. it shows 75 million young people around the world are jobless. that's 12.7% of those aged

between 15-24 with one in five in europe looking for work. it's a situation for which the united states is not immune. >> we have to make sure that there is a growth strategy to go alongside the need for fiscal discipline. as well as a monetary policy that is promoting the capacity of countries like a spain or italy that have put in place some very tough targets and policies to also offer their constituencies a prospect for improvement. >> the president sounds pragmatic, but there's little he can do to predict which mantra wins, growth or austerity. >> let's go live to steve, our correspondent in berlin. looking at these oecd forecasters, the diverging

trends between the euro and the u.s. has been stuck on growth. i mean, how much pressure is angela merkel now to change tactics? >> she's from immense pressure from president obama, from francois and in germany she's under pressure, but the other way. the sense is the opinion in germany is hardening against bailouts and the euro. if you look at tabloids in germany, an immensely popular tabloid paper says "europe doesn't need the euro." but the important thing is that subject is now debated in the biggest tabloid. it's come out, if you like from the fringe, the establishment has always said, we need need the euro and people mattered,

maybe we need the deutsche or maybe not, but it's now on the front page of the tabloid. >> and the oecd report says they have called for the e.c.b. to do more and it has an essential role to play. angela merkel is not going to be pushing the euro. she has to shift, surely. >> she has to shift but she says she is very pro growth. and nobody doubts her. the question is how do you get growth? she is adamant that you don't get growth by some kind of artificial stimulus. you get growth by sorting out your finances and making the -- financing and spending the european money in a different way.

they recommend the money could be spent differently, but they are adamant no more money can be forthcoming. so that this idea of a stimulus, a government push to the economy to get it moving up wards is going to happen. that's not what they think and that's not what they are going to do. having said all that, if the situation turns from crisis to catastrophe, if there were a run on the bank, all bets would be off and nobody quite knows what anybody would do. >> thank you, jamie. that's -- the oced saying it could be issuing euro zone and -- euros. and the e.c.b. could buy up government bonds. >> yes. but to a certain extent, they have run out of options. however, what they do put a lot

of emphasize on is reform. shifting to the press conference on the report. they were saying reform, which is generally considered. i've heard this so many times over the last few months, is generally considered to be a very slow-moving, rather ineffective way of getting any kind of short-term growth, the oecd is saying it confuse a quick effect on the economy. people are saying yes, we need reform, but something that's generally put off because it's generally slow working. >> let's listen in. >> more than seven members on a two-week mission, and they spend those 10 days roughly talking to multiple

stakeholders. officials, non-officials. checking views and debating policies that have been in place and policy recommendations. so it's a very animated exercise as is always the case in the u.k. in the spirit of excellent cooperation. as a global hub and island with a long-trading history, few understand the benefits of trading and history of trading in an interconnected world such as the u.k. but also the policy choices in a world where what happens in one country affects all others. it is therefore welcome that the u.k. authorities' policy approach has reinforced policy approach. the government is implementing strong fiscal consolidation to reduce fiscal risks. the bank of england has been nimble in viggede -- to support

growth. and you have to appreciate that we do not -- the validity of policy but of policies. and policy mix, which to us is really one of the reasons why this policy mix in -- >> christine la guardia talking about the economic picture in britain. and i think the i.m.f. are recommending that they cut interest rates. further. more at the website on all our continued economic news. careen la guardia at the treasury near london. the rest of the day's news. the olympic torch arrives. part of the tour in the u.k. ahead of the olympic games in a few weeks eats time.

here live in the west of england. kenya's athletes are coming to this part of the world soon including the country of world renowned long distance runners. a lot are still training in kenya. the bbc's correspondent has traveled to the training camp in iten to find out what the secret of their enormous success is. >> we're on a very basic track but the people running around here include the london marathon winner and top athletes. the time being the top 10 kenyan athletes are here because it's a town that lives and breathes running. they are running from about 6:00 a.m. and about a quarter of this town runs. school children and athletes all mixing together. gives you a sense of just how much running means.

also got someone here whose made the journey. an irish runner. what's so special about iten? what's brought you here? >> the altitude. you're here with the best athletes in the world. some of them have made their name and to train with them is great. >> and you've got people like you, ordinary locals who want to get that success. out training with world and olympic champions. >> yes. when you go out in the morning there's four or five people. you can join in with the groups. and gives you a lot of encouragement for your improvement. >> clearly for the young people, they see role models. do you hope some of that gold medal star dust will rub off on you? >> yes. and when you are here, you get to see where they train and you

always learn something when you're here. >> people talk about the altitude. obviously that helps. their diet. is there other things that help their success? >> it's a very basic lifestyle. they heat very health lyrics basic diet. then run day in and day out and month in and month out. >> when you leave here what do you take with you? >> the benefit of the altitude, first of all. that's the main thing. but you're taking encouragement from runing with these guys and hopefully you can translate some of their mentality. >> mr. dunleavy. thank you. one other factory is the poverty. 40% of kenyans are unemployed and many of these young athletes see the stars, the wealth and how well they have done. and they think they can get that success. >> we spoke to a 12-year-old

girl, a junior champion and the entire villsg rallying around her and they are hoping she will be the key to them getting out of poverty. but she doesn't senal to be feeling that pressure. so if you want the secret, it's a mixture of everything but really it's down to their success which looks as though it will continue. >> thank you. in iten. you can follow the progress of the olympic flame, itself. if you just go online. you can watch continues video of the torch relay and see some of the iconic places the flame is passing through at www.bbc.com/news. also if you want to stay in touch on twitter. just use the hash tag bbtorch. >> and the international space station. >> five, four, three, two, one, zero.

bbc how he felt after being freed. >> what about the terms of your being released? are you going to be able to reenter politics? >> unless they do that, i can do politics. but i can -- [inaudible] as it is, we don't know. >> ideally, would you like to re-enter the political arena and challenge for the presidency again? >> yes. it's not that i want to become the president of the country or something. my intention -- >> in march the united states

sponsored the human rights saying it should do more for reconciliation and certain issues for war crimes. >> yes. i agree with that. the reconciliation is yes, it's a must. but the war crimes, they are really differing opinions. so we degrees we will argue it out. i always believe they were on specific issues. we can clarify things. people need to answer

allegations of war crimes. so that is my position. >> fonseka former sri lankain' chief. next, the war against pollution. now, getting ready to elect a president. the first leadership vote since hosni mubarak. his 30-year rule was brought to an end after a wave of protests. but egypt's next leader is likely to be decided by voters outside the capital. >> politics always takes second place to the price of cattle out here on market day. but these egyptian villages are clearly enjoying the opportunity to choose their president after years in which they have been taken for granted.

>> in the past, if they said mubarak, it was mubarak. if it was another person, it was another man. now we have the opportunity to choose. >> the crowd pushes in. lots of hands. lots of different choices. to understand this election better, we traveled even deeper into the countryside. this is where it could well be decided. most egyptians still live out here, not in the big cities. >> on the face of it not much has changed since the revolution, but you will find people debating for themselves and speaking freely for the first time. that's what makes this whole election so unpredictable. someone always used to tell these people how to vote, the ruling party, the iman, the

family. now each candidate has to fight for their vote. >> the p.f. c-webb site says dried blood resident due -- the regan foundation has expressed its outrage. this is "bbc world news" world news. these are the headlines. the sri lankain' former military chief says he will cooperate with any war crimes investigation. >> coming up in sports today. viva, the new king of french football join their fans to celebrate their fist step. flame still burns. the olympic torch is almost 300

our work if there were none willing to participate. >> we met some of the regular volunteer tests. participants are paid often thousands of pounds. lisa signed up to pay for a family holiday. >> my mom was not just worried for me and the drug testing but also the actual effects for my children and how that would psychologically possibly affect them. so it was quite tough. >> claudia was a medical student about to start his seventh trial. >> humanity has to advance. it doesn't need to stay where it is. it needs to have more drugs put on the market which have fewer side effects and which are more efficient. >> but what are the risks, in

2006 a private trial based on this london hospital went badly wrong. six men went into intensive care after taking an anti-inflammatory drug. since then clinical trials have been regulation tightened. there's been a number of people applying to take part in this flu and cold medication trial. this year a the number has more than doubled. >> this facility is now in lockdown. a number of healthy volunteers have been placed into quarantine, infected with a weakened form of the flu virus and then given the drug that's currently being tested. this is as far as we can go, but they are just on the other side of that door. >> they will be in there for the next couple of weeks and

earning nearly 4,000 pounds. >> the volunteers will be in there. >> back at richmond pharmacology, it should be a quiet night. too much momentum could interfere with the results of the trial, results that will determine whether this drug goes on to become a licensed medication. jenny hill, "bbc news," london. >> a passenger train has crashed into a freight train in india busting into flames. the freight train had been stopped at a station when the express slammed into the back of it. >> and an earthquake has struck bulgaria causing residents to rush into the streets.

>> it can do so much. using artificial intelligence, it can hunt down contamination and reports back to shore in real time. >> once in, the robots can work alone without any control from the researchers. just like a real fish, it can maneuver easily in the harbor. >> with these fish, they can run autonomous lip and do the monitoring for you and if there's a leak or anything, these fish can find it out straight away in real time and track down the source of that pollution so we can put a stop to it straight away and reduce the pollution at sea. >> these protoo types cost $30,000 but they want to cut the cost so the fish can become a permanent part of the solution. >> much more at our website.
