>> hello, from al jazeera's head quarters in doha. this is the nuts news hour in doha. i'm jane dutton. a shooting at a free speech meeting. fighting continues just hours before a cease hour deal is supposed to take evacuate.

houthi and their use of force against protesters. [music] it's a big job but someone's got to do it. we meet the king of the carnival. >> we begin with some breaking news out of denmark. one person has been killed in the shooting in the capitol. copenhagen. danish place say they're search forgive two suspects. shots were fired in a cafe where a freedom of speech meeting was being held. >> bullet holes in the glass at this copenhagen cafe after an afternoon debate on free speech turned dead leaving one dead and police officers badly injured. guests sent tweets saying they were under fire but still alive as gunmen stormed the building,

spraying the cafe with shots when they could not get in. lars vilks, the one who has caricaturized prophet muhammad, organized the meeting. he has advised the attack. some have called the shooting an attempt on his life. he already lives under constant police protection. he said that he and others threw themselves on the floor as bullets came through the window. those who are at large are said to be danish speaking and stormed off in a car. denmark wonders allowed if they'll strike again. >> christina, a local produce center copenhagen.

she's on the phone for us at the screen where scene where this has been happening. have you been able to find out any more. >> i have. the car that the gunmen used at the scene has been found but the gunmen are still on the loose. the danish police are on the man hunt and trying to find these gunmen before anything else happens. we're getting more detail from the police about the gunmen, but they're being extremely cautious about what they're saying. they would at the press conference covered at the last hour, they would not give us any kind of details about the appearance of the men. very much being cautious, and not wanting people to jump to conclusions. really all they told us about the gunmen was that there were two of them, and they were danish speaking. >> how surprising is something like this? i know that lars vilks had been

threatened for many years after his depiction of the prophet muhammad but there was a security presence around him all the time. >> that's right. and clearly the security was a concern. they have been very wary over the controversy of the depiction of the prophet muhammad first came to the forum. there were attacks on western embassyies and lots of violent protests. this is something that denmark has expected. you don't see a heavy police presence on the streets of copenhagen but it is there. it's in the back of people's minds that something like this could take place. >> you said that it might take place but for those people there, those witnesses near the cafe they must have been pet treefied as they open fired into the cafe. >> that's right.

they were tweeting the events of the latest happening there. we've been told that the witnesses have been gathered in one place and they're now being questioned getting more information about the attack. >> thank you for that, christina. saying to us that the car has been found of thel assailants. to eastern ukraine where the latest cease-fire is due to come into force but it's looking shaky. threatening to empose marshal law if the agreement is not respected, and the rebel leaders will continue shelling the town of the epicenter of latest fighting. richard martin has more. >> it's hard to believe the cease-fire is just hours away as ukraine volunteers a blood which attempt to recapture a captureed

community of debaltseve and mariupol. the clock ticks down in hostilities. >> with the support of the russian army the militia are trying to solve tactical tasks to widen the territories that they control. >> clearing up this morning in the center of the city of donetsk after a residential block was hit by shelling, broken windows and shattered lives, two people died in this hit. in debaltseve the government holds and the rebels want. people in their way are being forced to flee. >> it's not quiet. we're being hit from all sides. >> despite the deal being hammered out in belarus, many are headed to the border. but they're holding out little

hope that the cease-fire will stick. >> an analyst at ihs live from london. it's not looking good. this dramatic increase in fighting ahead of the cease-fire. what do you think is behind that. what do you think all sides are trying to achieve? >> i think it's not surprising that there is a surge of violence because when when the parties were working and concluding that there were a peace deal they did not immediately announce a cease-fire, they gave 70 hours to the peace deal, and they're taking this as a window of opportunity to grab as much territory as they can. which of course will jeopardize a peace deal itself because now there is a big question, what will be the line of contact? is it the one that was agreed to back in 2014 or is it a new one which would reflect territorial games. >> yes you're right. so much has changed since the

first minsk agreement. you think it's not just been incorporated in the latest agreement? >> i think it's one of--i think it's one of the weaknesses of this peace deal along with many other outstanding issues. and but the bottom line is that both parties seem to lack the spirit of finding a peaceful solution. they haven't--it doesn't seem that they think that military solution is an exhausted avenue, and also there has to be a realization of their limitations, both military militarily and. >> the president has already threatened marshal law. we're looking at possibly marshal law and the u.s. could flood the country with weapons and saying it could punish

russia economically. >> when it comes to ukraine they need to stop the bloodshed but it is close to devault. one respect that could push ukraine closer to default is the russian loan that russia could demand an immediate payment of the ukraine's finances are in a very very dire situation. the country needs i believe some some--even if it's temporary some peace in the eastern regions to refocus on its finances on its economic situation to avoid a default. >> of course, we're seeing a humanitarian crisis growing as well. thank you. key members of iraq's parliament say they're suspending their participation in government after the killing of a sunni tribal leader. we warn you that some of the

images we're go to show you are disturbing. among a group of 12 people kidnapped by a shia group in baghdad and then murdered. the act was condemned, it was described as heinous and unacceptable. two sons of an iraqi also dead. let's go--before we get to the political process let's talk about the killings. any more about who was behind it and what their intentions were? >> there have been no details released so far but what the iraqi government has said they're mounting an investigation to try to find out who was responsible. it has to be said that one of the check points that allegedly where they were picked up and taken from was actually a militia check point. this was own a routine procedure.

we saw one of the mps was released badly beaten with a broken leg. then after that we saw bodies turn up the iraqi government saying they want to investigate this. they're pulling out earlier and it looks like more groups will follow. >> that's a real problem the new government was to be all inclusive to stamp out groups like isil. >> you're absolutely right. they're bringing about a very united national unity government. that's likely to be derailed as well. this is a very big political crisis going on here in baghdad. lots of meetings going on right now. the sunnies are very angry.

the only way they can pull themselves out of this crisis. is if the shia-led government is if there is an investigation this was a very brutal crime. including the sunnies. this was an insult not only to their political party but for all sunnies here in iraq. it's a very delicate thing. what needs to happen very quickly is this investigation needs to happen. there needs to be a very visible investigation, and the culprits need to be brought to justice quickly. if that does not see happen, we may see more tit-for-tat revenge. >> thank you. we have a lot to cover on the al jazeera news hour. mending their ways, we report from nigeria's niger delta

bringing peace to the region. >> separated by occupation, we meet a palestinian couple determined to keep their love alive. and there is no place like home for australia. a big score against england in the cricket world cup. >> talks are being held in yemen between houthi rebels and the party of the former president ali abdullah saleh. it comes after houthis took power in sanaa triggering protest across the country. >> angry protesters set fire to a shia houthi vehicle in yes hen's third largest city. they say the car was being used by the houthies to prevent them

from holding a demonstration. you this is one of many predominantly sunni region where is anti-houthi sentiment is on the rise. this is the city south of the capitol of sanaa. the shia houthies are in control of the city, but people are worried. protesters are out on the streets to denounce what they say is a houthi crackdown on activists and opponents. >> they kept beating me, torturing me for hours. they wanted false confessions things that i was never involved in. they wanted me to lie to say that other figures were paying us to protest against them. that american and british organizations are investigating the youth in in yemen against them. all lies.

>> anti-houthi protests are spreading across the country. in the city of ibb many gather in the main square to express their solidarity with president hadi who was recently forced to resign. last week shia houthies dissolved parliament and said they would run the country on their own for a period of two years until elections are held. the coup was denounced by the international community. the u.n. is renewing efforts to bring the factions together, including calling for new powers for its envoy. many countries have evacuated their embassies in the capitol of sanaa including the usa which has been actively engaged in drone attacks against al-qaeda in yemen. >> we do not coordinate anything with the united states when it comes to these reports about their airstrikes in yemen.

we only coordinate with the yemeni army. we reject the u.s. involvement in our internal affairs and the interference forces some to give support to these terrorist ever groups. >> you al jazeera,. >> mohammed, a former adviser to three of yemen's past advisers. good to have you with us. let's talk about the two main issues. the violence and you had talks. let's start with the violence. what do you make of the way the mouthys are treat--the houthis are treating the demonstrators. what is behind that? >> the houthies want to rule by hook or crook. they're using all oppressive measures and they're losing ground. they cannot control more than 20% of the country by any way.

i mean, this is quite serious now with the all the embassies shutting downish and then this is a negative development which--since the country is heading downwards towards internal conflict and chaos which the former dictator has been threatening to take over the country. >> what about the support they have outside of the country? the u.n. issued a report condemning some of the action taken by some of the houthies and foreign intervention. who are they referring to here? >> well, it's obvious that it did aim at individuals and entityies which will derail the political settlement. and obviously the--i mean, the

entities it means iran, hezbollah and the rest of the people who are pushing the country towards this sort of end. houthies are really, unfortunately, are being encouraged by the u.n. envoy who is being rather reluctant to point out their mysterious ways of dealing with the country. they were much more courageous when one week ago they did accuse the former dictator and the houthies to be the ones responsible for derailing the whole political settlement. >> i was going to ask you let me jump in here. i was going to ask you about the talks between the houthies and the former president saleh what are they hoping to achieve? >> well, one group. this is a group-- >> that's what i'm asking you. >> yes yes they're not more than 20% of the country. so they're one group which

we're ruling the north of yemen for a long. there are corrupt centers that have been governing the country and now they're trying to spread across, which is not going to be accepted by the rest of the country. but as i was mentioning, we need a new initiative. they should have been more courageous in pointing tout that the houthies and the former president are the ones derailing the settlement. instead of saying all yemeni parties are responsible for the failure it is facing. he needs to be more courageous or he's shooting his own foot by the position. they did threaten to take measures against all those who are responsible for derailing the settlement. unfortunately, we have not seen the commission, the--there was a commission that was formed for sanctions. it did not report back to the

u.n. council and it should have been named. names who are responsible for whole mess up with the country facing now. obviously the houthies and iran, they're choosing some sort of choice they want to bring the wholethe whole on the heads much everybody. that is quite serious. we have our brothers might be now, and they should be more affirmative and proactive in. facing the security and the peace of the region. >> thank you very much. >> thank you. >> italian government has said it's prepared to intervene with libya to combat the islamic state in iraq and the levant. it said that the group had captured the city of circumstance arte. now they had been controlled by forces loyal to the national congress in tripcally. dominick kane reports.

>> a convoy of trucks parades through the town near sirte. these are fighters affiliated with the islamic state in iraq and the levant. for weeks forces who say they support isil have become increasingly more active in libya, and now they say they've taken sirte. they've given supporters of the libya dawn coalition until sunday to get out. the deteriorateing situation prompted leaders of the general national congress in tripcally to hold an emergency meeting on saturday. >> we have huge reports by the ministry and intelligence service that the city is now under the control of the group and it does not recognize the libyan state. we're trying to identify their true identities and where they came from. >> the presence of isis linked to isil on the mediterranean coast has alarm am stones on the

ed some countries countries. >> in the eastern city of bengahzi, former general haftar and his forces have been fighting supporters of libyan dawn. haftar support another parliament, which is based in the city of tibruk. on friday one of his field commanders suggested they would sunny retake substantial parts of bengahzi. >> we are currently in the special forces barracks. as you see that's the traffic light opposite here and we're heading towards--we hope in the next few hours to liberate it as we hope and pray. >> but haftar's men have made such statements before. and for now the fighting among the many armed groups in libya continues. dominick kane al jazeera.

>> hundreds of protesters have rallied in about a iran's capitol to mark four years since the start of the country's up rising. activists have up loaded videos showing running battles with police in several suburbs. they say dozen much as people have been injured. this video appears to show a child being arrested. the demonstrators are mainly shia muslims calling for political reforms from the reigning sunni royal family. nigerian government says that it has forced off attacks. locals say that the group open fired as they opened the city on saturday as they through leaflets calling for the boycott of next month's general election. the attack has called for a curfew in the area. now the northeast isn't the only part of nigeria with a recent history of violence. the southern niger delta was

part of fighting. from niger delta. >> this woman is still new at this. the nigerian government granted amnesty to fighters for the group of former fighters like her. they get a basically balance and they are taught a trade and an incentive not to attack oil pipelines and kidnap foreigners. but she said she still can't look after her two children. desperation could make her go back to a life of violence. >> i don't want to go back. i do not want to go back to that. >> these creeks are quieter than

they used to be, but armed groups still hide out here. men largely disbanded when many accepted the amnesty offer. the men were paid to keep their fighters away from the oil pipelines. the fighters were well armed. they would also destroy oil pipelines and kidnap foreigners. after years of fighting in the creeks former warlord pastor ruben now lives a comfortable life largely financed by the amnesty program. one he does not want to give up. he knows that could happen if president goodluck jonathan loses the election in march. >> if for any reason people who are desperate of power push goodluck jonathan out, i don't think there will be peace in the niger delta. >> the niger delta is where 90% of nigeria's oil comes from.

but this is most poem live. poverty and frustration could make it ease for former war loads like pastor ruben to find new recruits. they believe that the amnesty was a short-term solution that benefited only a few. >> if you didn't qualify arms, you didn't qualify for amnesty. the question therefore is the people that have potential to carry arms, that have not carried arms, what do you do with them? they are the ones that are left out. they're the ones who will carry arms in the future. >> the struggling single mother says if things get worse then she'll reluctantly join any warlord who offers her a way out of poverty. al jazeera, in the niger delta. >> stay with us on the news hour still ahead. >> deep in the russian arctic. inside each of these doors is an ukrainian family. keep watching to find out what they're doing here and what the

future holds for them. >> a red hot start up to internet institution. we look back at ten years on youtube. >> canada's yukon territory. i'll be looking at how scientists are studying the amazing athletes, the yukon arctic ultra to learn how conditions might be for humans in space.

>> america's first climate refugees >> this is probably a hurricane away from it being gone. >> who's to blame? >> 36% of land lost was caused by oil and gas industry... >> ...and a fight to save

america's coastline. >> we have kinda made a deal with the devil >> fault lines al jazeera america's hard hitting... >> today they will be arrested... >> ground breaking... they're firing canisters of gas at us... award winning investigative documentary series... the disappearing delta only on al jazeera america >> hello again. you're watching the al jazeera news hour. one person has been killed in a shooting in denmark's capitol of copenhagen. danish police say they're searching for two suspects. shots are fired at a cafe where a freedom of speech meeting was being held. a cease-fire agreement in eastern ukraine is due to take effect in a few hours is looking shaky. there has been intense fighting

leading up to the deadline. key members of iraq's parliament are suspending their participation in government after the killing of a sunni trial leader. monk a group of 12 people kidnapped by shia group in baghdad, and then murdered. let's get more now on the top story. the shootings at a cafe in copenhagen. joining us is a terrorism analysts. thank you for joining us. what do you make of what happened at that cafe? >> i know the layout of the cafe very well. it's one of the centers, the cafe. there were 50 people gathered there, including the french ambassador to denmark, as well as lars vilks, the controversial

artist who has a bounty on his head by al-qaeda: one suspect open fired on the building, with an automatic weapon. of course, there was one person injured. one person dead. three police officers injured and two assailants disappeared in a car under fire. and they are now in copenhagen, and the police are searching for them. >> any idea who they might be, and the style of the attack, does it tell you anything more about them? >> well, i mean, it was an automatic weapon that takes time and care to get. it's not so easy, and of course, you know, the target was the meeting place and potentially

lars vilks. of course, we need to know who they are before we can draw any huge conclusions. any widespread confusion. but it's very much a rerun of the charlie hebdo situation. luckily there were police officers on the scene but it's too early to know who did this. >> let me ask you about the daneish security service. they said that the shooting at the free speech event was likely a terror attack. it's quite a loaded statement a terror attack. i raise that because of the killing chapel hill killing with three muslims have been killed. why do you think these three words are specifically being used. >> because you have another state president the french ambassador as well as lars s

vilkss. there were no other reason for why they would open fire in that fire in that area, it was clearly aimed at the meeting taking place inside. >> good to get your analysis. thank you. let's get more on ukraine. the warning from petro poroshenko that he'll impose marshal law if a peace deal is not kept. we have more from eastern ukraine from donetsk. how is that statement going down and what do you think has prompted him into saying that? >> well, i think the prompt comes from what has happened certainly in the last 48 hours or so since that truce agreements with signed. we've seen a big escalation in

shelling certainly around hot spots in the town of debaltseve. it has to be put into context what have was said in recent hours. basically, separatests will stop shelling areas in the self proclaimed donetsk people republic. except for debaltseve. he said that it was not talked about in the minsk agreement. he said if any of the ukrainian soldiers and there are thousands of them reported to be surrounded in that town, try and break out then they will be met with dire consequences. he actually said if those attempts were made by the soldiers, they would be stopped and the enemy eliminated. so very harsh words coming from

the enemy as well as president petro poroshenko. >> you've seen how reluctant people are to obey the cease-fire. i'm talking about the fighters. tell us what else is going on on the ground. >> well, we left the ukrainian side early this morning the ukrainian controlled area this morning. there are a lot of troops in that area and a lot of heavy shelling. we then came across the borders. we spoke to separatest fighters at the border check points, who were at the time setting up mortar positions. they were saying that they were preparing certainly for--what they described as a battle in the night hours before this truce is supposed to be implemented. we came in to donetsk it had been very quiet in shelling in the important. there were shells that landed very close to a press conference being given or being prepared to

be given by the separatest leader at the time. one of those shells landing in a residential area killing three residents. and then it went very quiet again. but it's literally in the last 45 minutes to an hour we're hearing increasing shelling here around donetsk. in the last 15-20 minutes we heard grad rockets being fired as well. some very different language being given by respective leaders, and seemingly things deteriorating if we like, the closer we get to this time for the truce to start. >> all right, thank you for that charles stratford. >> well, for many ukrainian who is have already left their homes, any cease-fire is already too late. since the fighting began a year ago hundreds of thousands of people have fled to russia. 40,000 or so and some areas are

taking up 200 refugees a day. some are sent thousands of kilometers from their homelands. we go to the arcticcy of mur america's unsk where many ukrainian refugees now live. >> itthey left behind a house and everything in it. now they share one room and a college dormitory. they haven't even a spoon or fork when they arrived. but this family does not do much complaining. >> he started work as a builder on a construction site. a month ago he got work at the port. a representative from the company came here and said he needed men. several guys from the dorm got jobs there. i work as a shop assistant. >> the dorm houses 53 ukrainian refugees at the home down from a peak of 128. since december 1st they've been paying their own way after the

russian government shut off financial support. thankfully most have picked up work. home may be thousands of kilometers away, but these days the internet keeps friends and family connected. christina is getting news from luhansk. >> why didn't you leave? >> i didn't get the chance to go. >> it's because of work. she had a job and a salary. now they can only work half a day. they want to leave but they can't. you need to get a permit to leave the city. >> the winter nights are long here. it's colder. not all the locals are happy with ukrainian refugees taking their jobs, and the accompanydations are cramped. but as the man overseeing the building points out all that have is preferable to what is going on at home. >> the only motivation for them to stay and go and safety. if it's more safe here they'll stay. >> now a third grader at a local

school. it's entirely possible that he'll graduate, find a job and start a family here. ukraine will just be a fading childhood memory. >> in malaysia protesters have been rallying demanding the release of anwar ibrahim. he says that the charges are politically motivated. one palestinian couple separated for years by the israeli occupation will be spending the day apart yet again in the occupied best bank. we have their story. >> it's become a routine for rashe and dalia. nearly every morning they log on to their computers and video chat with each other for at least an hour. they've been doing this for almost four years after a

meeting in a conference in jordan where they quickly fell in love, and soon after decided to get engaged. >> she's so affectionate and climb. dalia is very loving. that's why i want her to be the mother of my children so she can teach them how to be like her. >> but he lives in the occupied west bank while dalia lives in the gaza strip. they need permission to see each other, a request that has been denied. after nearly four years of trying to be united, i asked if she ever feels like giving up? >> at times i get depressed. i feel like i don't want to go on. i think to myself why did i throw myself into this tornado. when will it be over? when will the humiliation end? >> the separation of gaza and

the west bank affects thousands of palestinian families. according to human rights groups israel routinely prevents palestinians from passing through whether it's for weddings, funerals or other social reasons. something that has been described as unbearable for families split between the two areas. >> they say for security reasons, but of course, one cannot accept this argument. it's a very sweeping argument saying that all the people are security threats. >> friends have started a facebook campaign called "deliver the bride to the group" and hope that it attracts the attention president mahmood abbas, who they believe can help. that's why dalia remains optimistic. >> love is stronger than politics and we'll make our dream come true and live together forever. >> until that happens, they will

have to settle for moments like this. al jazeera, in the occupied west bank. >> make sure you stay with us, because robin will be here with all the sport. he'll tell us if england have managed to continue their promising start at the six nations tournament.

>> ten years ago sharing videos online was a novelty. then three americans started a website called youtube. these days it has more than a billion users and it's one of

the most profitable sites in the world. technology takes a look at how a small idea became big business. >> here we are. >> this is the first video ever up loaded to youtube. the company's co-founder joey at the san diego zoo in 2005. >> the idea that anyone, anywhere could share their videos online caught on fast: just over a year later 65,000 videos were being up loaded each day, and youtube was getting 100 million daily views. no surprising when this happened. >> today we have exciting news for you. we've been acquired by google. >> 17 months after going live youtube was bought by google. for $1.65 billion. >> google has this very large-scale infrastructure for quantum delivery, and youtube

would not have been able to do it if it was just a similar start up by a few guys. >> with the backing of google, the site's influence and open access policy made it a powerful force. >> no longer do people have gatekeepers, radio stations, tv networks movie studios to get the word out on content they've created. instead, anyone can create something and distribute it to the world. >> and with a billion people visiting the site each month, a new generation of online stars have found their audience. triesing on the sites and the revenue sharing system means some are making millions of dollars each year. >> now once they have built an audience they can do merchandise, brand deals concerts if they want to. so it's really reduced the barriers for anyone to go and build an audience and monday advertise. >> it's also seeing a wide

variety of educational religious and charity groups, post lectures, guides, and tutorials. changing the self-education industry. more than 300 hours of video is up loaded to youtube every minute. making it difficult for the company to stop violent sometimes explicit videos were being posted. >> this is the challenge as well as the opportunity. you can have this huge platform that anybody can up load anything. it can have huge positive net value but negative net value as well. >> as many people connect to the internet and their bandwidth i am poor, the popularity of youtube is likely to increase. they hope to continue to dominate audiences and the revenue that they bring. >> there is money to be made. >> there is money to be made.

exactly. >> what's happening? >> there is plenty going on. the new zealand and australia open their campaigns with victory. >> redeveloped in the 2011 earthquake captain brandon against sri lanka. he would be called out having scored 65 from just 49 bowls. williamson with 57 at the black caps with his 13th. cory anderson top score was 75 from 46 bowls as new zealand finished from their 50 over.

despite 65, sri lanka never got close to the targets. captain matthews fell short when he was called out. sri lanka all out for 233 giving new zealand 98-run victory. >> we're excited for the win. >> it must an long road to go. >> there is a big opening win for australia in melbourne. after being dropped on his second bowl aaron finch went on to score his runs against england on his home ground. glen maxwell added a half century. stephen finn became the first englishman to take a hat trick.

troubles continued the england captain got his fourth in the last five matches. like fin marsh would take five wickets. steve smith with the diving catch to remove butler 92-6. james taylor tried to keep the visitors in the game he was on 98 when australia caught the final wicket. the decision was reversed on review but then james anderson was deemed run out on the same delivery. england all out on 231 australia winning on 111 runs. al jazeera. >> six nations rugby continues. in action right now it's the irish who enjoy 18-11 lead. that's the score there.

england scored six times. england now notched that at 21 wins with 21 games against italy. the italians, though, it's a defeat from 18 games. maintaining the eight league, the champions thrash their opponents as you can see from the score 8-0. all netting two in the route. idle preparation for champions league tie. well let move up to spain now. the coming up to full time with the match. real now just seconds away from wrapping up a 2-0 win which will put them four point clear of bar

6 kilometers. many drop out because of the extreme cold. the race is providing scientists with a chance to study how people cope in such harsh conditions. >> racers in the uconn arctic ultra spend days, weeks even crossing landscapes like this. seemingly endless expanses. temperatures that can freeze exposed skin staying on the move taking food and water managing your pace. then there is the long northern winters night. it's colder. you're alone and you have to choose. do you keep going and get fatigued or sleep and risk hyperthermia? it's a constant challenge and frightens even front runners. >> it was minus 50-52, i don't know, i was freezing. i kept going at that high speed. but i didn't get warm at all. impossible. >> after that horrible night the current race leader is tested by a scientist from berlin's center

for space medicine. heart rate, sleep patterns and body rate are neured. he fills in a question mayor about his state of mind. three others are taking part as well. >> the idea is to increase mankind's knowledge to put this in a broader perspective about the human physiology. the adoptability of the human body. >> isolation endurance and extreme continues the cold all of these are relevant to greater understanding of the human body, and finding out what it might be like for human beings in space. with the yukon winter at its worst, it is not nearly as severe as what is beyond earth's atmosphere it is a handy proving ground for space exploration and the return of space explorers to their home planet. >> astronauts are required to do

survival courses and survival training and you know, it's quite possible, it's my hope that this study might help to increase their chances of survival should they end up in an environment like this one. >> for most runners this is a race against time, weather and other competitors. for scientists, a chance to explore something little known how fragile human bodies can and do survive extreme stress. near car maximum in the uconn. >> that is the sport for now. >> well, brazil's biggest party of the year started in rio de janeiro. 100,000 tourists are expected for the five-day carnival. as lucia newman reports the city's new carnival king has begun his reign.
