huge military exercise. we meet these teenagers from sgan whose dreams of a-- afghanistan whose dreams of a better life turn into a nightmare. we begin in yemen where government forces say they've recaptured parts of taiz. the city has been under siege by houthi rebels for nearly a year. forces took key areas in the west and the south of the city. rob matheson reports. >> reporter: cheering crowds welcomed the news that forces the president appear to control western and southern parts of yemen's third largest city. >> this was not expected and it shocked the houthis. they were in control yesterday of many parts of taiz where

today it is only in the strategic areas. >> reporter: pro-party forces of the coalition are said to have broken through the houthi blockade but also opened a key supply route from aden. >> hundreds of fighters who were allied with the houthis switched sides and this was the main reason why taiz was able to fall into the hands of government forces so quickly. the houthis right now are blaming each other, trying to find answers of why this happened. >> reporter: supplies may not be delivered. in november forces launched an offensive to take back tairz.

it is held between the capital and the southern port of aden which they took back from houthis in july. now coalition air strikes and government forces are said to be targeting houthi bases to the east of taiz. >> translation: the siege of taiz was broken. this is a big issue. the wheels have started to roll. it might seem slow, but the efforts are huge. >> reporter: the rebels say they're sending for reinforcements and to take back the areas they held. rob matheson the u.n. is warning of a humanitarian crisis across yemen. it says nearly 2,800 civilians have been killed since the conflict began last march. more than 5300 yemenis have been injured. 21 million people, 82% of the population, need some kind of humanitarian aid and more than 2.5 million people have been

forced from their homes. i'm joined now by the u.n. humanitarian coordinator for yemen, jamie mccoldrick joining me on skype. good to have you here. this partial lifting of fighting in taiz, how is it impacting those on the ground? what's the situation there? >> since january we've been working very closely to bring material into the taiz area, both inside the enclave and elsewhere. we've been successful to do that. the chance to bring in more material, we delivered trauma kits and oxygen bottles. this is an opportunity to address the situation inside, at the same time very conscious of the crisis and the population is moving because of the intensity of the fighting i'm hearing that so many people are displaced and we're expecting those numbers to grow. what are we looking at some in >> in the area itself, the taiz

city, about 600 displaced people already in a population of 400 million. it aggravates a bad situation already the security situation now, in a place like taipz? how much will you be allowed to do, do you think, and can you give us a sense of what you're expecting to find there, what the needs are? >> we visited there in january so we saw for ourselves. clearly the hospitals, there's mention of food and gas and food and until supplies. these are the essentials to get there but beyond that, there's a large operational area that requires assistance. displaced people and vulnerable populations there. any reduction in intensity of fighting, any ceasefires that take place offer an opportunity for the humanitarian community to address those needs much

better and more regular assist particular way. it has been very ad hoc so far. we've been asking both parties to give us a chance to deliver regularly in those areas many people there had needs before the war broke out anyway. >> yes. yemen is probably the poorest country in the middle east. a difficult country to work in and live in. people struggled with daily life. the war brought an increase in all of those problems and the poverty. peace for us is important. if you bring about a peace process that will bring an end to the war and people going back to a normal way of life again it is not taiz. as you say many people are displaced and we've seen the same sort of situation in taiz and other places in other cities >> throughout the whole of yemen the figures are staggering. there are pockets very severe and vulnerable where it is quite severe. that's where the population are

most greatest. we of the humanitarian community are trying to meet those needs in a balanced way to meet populations before the situation becomes worse thank you very much for talking to us about the situation in yemen. >> thank you u.s. secretary of state john kerry says talks to end syria's conflict should go ahead on march 14 despite possible truce violations by government forces. this is according to a u.s. pool reporter accompanying kerry. he met the king of saudi arabia at a military base near the vau de-iraqi border. they've offered to send in ground forces to syria. for the second time in two weeks, demonstrators took advantage the temporary ceasefire to protest against the bashar al-assad government. marches with were held across the country in at least 15 cities where people were seen chanting sdloe begans against--

slogans against the government. the greek government says it plans to clear out a makeshift refugee camp at the macedonian border within two weeks. on friday tensions in the over crowded camp spilled over as people to youing for food aid. macedonia, along with other balkan states, have shut their borders to refugees. refugees in afghanistan are in the hundreds of thousands trying to get to europe in search of a better life. for children, the journey and risk of being deported can be terrifying. >> reporter: it is a moment of respite in a life otherwise filled with hardship, loneliness and uncertainty. teenagers who dared to dream about a fresh start far away in europe. >> reporter: no news at all? >> no. >> reporter: like this

17-year-old, he smuggled his way to the shores of greece >> the smugglers ordered me to bury my hands in snow for five hours. i was taken away and i don't know where my family is. >> reporter: unable to move forward from here as afghans are no longer welcome on the balkan route. this 16-year-old is in the same situation. >> translation: they were trying to deport me because i did not have a passport. so i left. i want to be in a place with no weapons where i feel safe. i saved the money to pay smugglers. i also borrowed money from my friends. now i'm so sad to be stuck here. >> reporter: along the way he became friends with this boy who is a year younger. they snuck across borders and slept along the way and picking

up clothes left by refugees. they relied on food left on the trail but some of his friends did not make it >> translation: there were two teenagers were us. they wanted more money. they remove their money and they still did not have enough. they were taken away. i don't know where they are >> reporter: the camp here is teaming with you accompanied children. many say they're 18 fearing they could end up in a shelter for minors. others claim they're travelling with relative, so they go unacted for and unpretected. >> reporter: every day there's a count of how many there are in the camp because despite the border being closed, people want to reach their designation, so some take their chance at crossing the borderline. for $1800 they're promised safe passage all the way to germany. it will mean more deaths and

more suffering. this boy is over whelmed by a sense of loss. at 17 he has little to live for >> translation: if they don't open the border, i will kill myself. if i have to go back to afghanistan, i will die there, so i might as well end it here >> reporter: europe is crumbling under the endless flow of refugees, but the lonely children have been abandoned by everyone. the border closures are only increasing their vulnerability and the very real of them ending in the wrong hands u.s. presidential hopeful donald trump was forced to call his rally in chicago on friday night. it came after violent clashes between his supporters and hundreds of protesters. he has cancelled another rally listed for sunday. >> reporter: people who protested against donald trump

here, it didn't take long for things to get heated inside. the crowd and to be split around 60% donald trump supporters and 40% opponents. just as the rally was supposed to start, the campaign cancelled it >> after meeting with law forcement, they determined that for the safety of everyone here, the rally will be postponed until another day. thank you very much for your attendance and please go in peace. >> reporter: that didn't happen. protesters and donald trump supporters exchanged angry words. fights broke out. a man tried to take the stage. after a struggle security officers removed him. a large contin jept of police came-- contingent of police came in and cleared the arena. there were clashes then outside. in an interview with ns n.b.c.,

donald trump said he made the right decision to cancel but said the anger wasn't directed at him >> you have people that are very, very upset about is happening with the country as a country and you have other people that just don't feel right about things. those people outside, they were coming inside and rather than having everybody get in and mix it up, i thought it would be a wise thing. >> reporter: protesters gathered outside the arena long before the event. dozens of tabbing you willty of staff at the university had petitioned school administrators to cancel the rally. when it was all over donald trump supporters were disappointed. opposers were disappointed. >> i wish he would have came and

supported us, but at the end of the day i'm still voting for him. nothing has changed north korea says its military is ready for pre-emptive attack against the south. the announcement comes as naval exercises take place in south korea. the drills are being described as the biggest ever following pyongyang's recent nuclear long-range rocket launch. >> reporter: this exercise is a show of force that is always meant to impress. the u.s. say it is non-provocative. they have told the north koreans about what has taken place here. it says it attributes to the surety of the reason. they-- security of the region.

this year the contingent is larger than ever. 17,000 working along 300,000 of the south korean officers. we have had the nuclear test earlier this year and last month the long-range rocket launch. all of this has worsened relations. we have had the sanctions by the u.n. and south korea moving the relations between the north and south as bad as they can get more to come. scientists develop a model to predict weather conditions. >> if she was to be positive on the doping for a certain substance, then there should be a certain kind of consequences for that

novak djokovic weighs in maria sharapova drug test failure. an israeli air strike has killed a 10 year old child in gaza. shrapnel from an air strike hit the child's home. the strikes came off several rockets why fired on friday night causing-- were fired on friday night causing no injuries. the iraqi phenomenon ee has declared hezbollah a terrorist group. the move was supported.

who is hezbollah? it is a lebanese shia muslim political organization with an armed wing. they are fighting in syria to support the government of president bashar al-assad. it was formed in the 1980s when it began a struggle to drive israeli fighters from the country. it has several seats in the lebanese parliament and ministers in a national unity government. the arab league and the six member g.c.c. have been ramping up pressure on hezbollah which is backed by iran. the two nations on opposing sides of conflict in syria and yemen. i'm joined by a political professor at kuwait university. why this move, why now? >> this move is because hezbollah has changed tactic from a resistance movement, when

israel used to occupy the territory. we were supporters then, but since 2011 hezbollah has shifted its tactics and became part and parcel of the iranian project to be the dominant power in the region, and it has been now wreaking havoc in syria and playing a role within the iranian fear of influence of abating, supporting, training and helping terrorist organization and cells discovered in kuwait a couple of months ago. they have a major accusation against them. plus there has been now evidence by the yemen government that was

shown on saudi television that members of hezbollah militias have been training and helping the houthis carried out the major coup against the elected yemeni legitimate government, helping them and launching attacks against saudi arabia and even carrying suicide missions without riyadh labelling hezbollah a terrorist group, is this pushing sectarian issues to the forefront. is it just against iran? is that's what is going on? >> iran is the one that pushed and is still pushing sectarianism. it is supporting those regimes in the region. it's the regime of bashar al-assad that ask massacring his-- is massacring his

population. the party that is pushing sectarianism and fanning the flame is iran. it is bringing them as far away from afghanistan and pakistan to fight a war that is not their way in syria. when we try to deter this project of sectarianism and domination in germany, now we are being accused of fanning the flame of sectarianism. we're just trying to create some deterrence from interfering in our fears and undermining our security and stability in a region that is witnessing major shift and realignment in many places and many parts of this region thank you very much. >> thank you the u.n. security council

has adopted its first ever resolution to deal with sexual abuse by peacekeepers. the agreement calls for the repatriation of those accused of sex crimes. the move was sparked by a u.n. report that showed a sharp rise in the number of allegations. 69 cases were reported last year. that's up from 52 in 2014. >> the res lieuing underscores the peacekeepers found guilty, not those accused, those fund guilty, of committing sea do not deserve to serve in u.n. peace-keeping missions. sending a clear message to troop and police contributing countries who failed to take action to prevent or punish credible allegations of sexual abuse and exploitation, awell as too all members states and to u.n. bodies to ensure that these investigations are carried out thoroughly, promptly and impartially in peru many have marched, o

threatening people's lives. >> reporter: this is 4 kilometers to get water, 4 kilometers to get back. once in the morning, again in the afternoon. 16 kilometers in four hours of walking every day. >> translation: we're really suffering because of water. every time i go get water, it shaves off years of my life >> reporter: she is among 50,000 afghans in this district who don't have access to clean drinking water. the district sits along afghanistan's border with iran. years of draught have depleted the nearby river drying up 60% of the farm lands leaving many jobless. decades of war have delayed construction of water storage facilities. its gruelling journey is the only way to reach hand dug water holes. >> translation: if we don't do

this, my family goes first tea. there's no water for 50 kilometers. thirsty-- >> reporter: in rural asia and africa, women an children walk an average of 16 kilometers kilometers a day for food and water. it robs children of education. >> reporter: six years ago the trek for water turned deadly. when young boys went to fetch water they were shot and killed by iranian border guards. villagers say it was the border guards way of sending a message. >> translation: i found my son near some bushes by the well. he had one wound on his wrist and one chest and his side. when i saw his bloody clothes i blacked out. >> reporter: a government official denied the allegation. they say they could have been smugglers, but tension between the neighbors assist as iran too

faces a water crisis. this man sits on a committee that manages the region's water supply. he says plans to address the crisis exist, but have been delayed by war and a lack of funding. >> translation: the solution is to build canals and wells. we are aware of the problem and plan to address it >> reporter: until them, a gruelling journey for water remains a daily netanyahu for decades scientists have been debating what causes extreme weather events. a team says it has developed new techniques that could link human activity to droughts and cyclones. it is offering alternative ways to predict them. >> reporter: these are plants that are clogging the water here. at the end of a long and unexpectedly hot summer. in a continent suffering under

the effects of el nino, many would welcome a new science that will tell them when there are adverse weather conditions to strike them. this is a new branch of science to seek human activity to events >> it moves us forward in our awning so we can predict the events months in advance or perhaps even years in advance. >> reporter: until now scientists have compared general computer models to work out what is going on. is human activity changing the weather or are we looking at effects on the planet that has warmed and cooled in the past. we all know the weather, or we think we do. it is a cool episode of summer's day at the end of one of the hottest summers anyone can remember with temperatures through the roof but how many of that is attributable to climate change, greenhouse emissions and

others. attribution seeks to end the debate. new and significant number krumplyging linking different scientific disciplines that establishes the human contributions to extreme weather with absolute precision. it is being compared to the u.s. surgeon general's report in 1964 that linked smoking to cancer. >> better global climate models could help. a better understanding of some of the science and the physics involved could help. better use of observational data sets and records could all help on that. so that's on the science side. on what would a person, let's say, who is responsible for safety or for the welfare of people using, i think it would be very good if she or he would understand now that, yes, science can do this attribution and to really look at that risk factor. >> reporter: since the panel on climate change in 1995, the

world has moved a long way to halting climate change and limit emissions. this group seeks to accelerate those efforts here is steph with the weather >> we've been suffering really badly in south america with a lot of rain mostly caused by el nino rather than climate change. el nino is the warming of the pacific waters. it affects the weather around the world. one of the things where we see an awful lot of rains is across parts of south america. here is the area of rain that we've seen. it has been stretching from peru all the way down towards the southern parts of brazil. it has been sao paolo where we had 150 millimeters of rain in two days. that causes a major problem with flooding. you see people having used boats to get around. they have been swimming through these flooded streets. it has been bad there.

it's not the only place. that system extends all the way back towards peru there and peru has seen a lot of flooding in the past few weeks and yet more rain means yet more flooding here. these are the pictures we're seeing out there. it seems to be getting worse. unfortunately, over the next few days there's not going to be a great deal of let up for peru. you can see the dark blues there indicating we're expecting heavy rain. some of the worst of that is likely to be in the northern half of the country where we already have that flooding. more wet weather over the next few days. further south more dryer and in rio there will be the occasional shower thank you for that. lots more to come, including a turkish town that has been nominated for the noble peace prize by its own government. plus how the world's top golfer

the top stories. yemen's vice president has announced that the houthi siege of taiz has been broken after his forces advance in parts of the city. he said relief efforts will begin immediately but fighting continues in many areas still. u.s. republican presidential hopeful donald trump has cancelled his campaign rally in chicago. fights broke out between his supporters and demonstrators.

he has also cancelled his rally for sunday. a camp will be cleared out within two weeks on friday. tensions in over crowded camp rose as people faug for food aid. the town of killis has been nominated for the noble peace prize. the party put in the bid and says europe should look to the town as a model of human rights protection. >> reporter: on the hills over looking the turkish border you can see camps. a few kilometers to the north is the town of killis which serves as an example of what can be done to help outside syria if the will is there. 90,000 here have been joined by 120 thoushg syrians who turkey has refused to turn its back on. they have set up businesses and

work together with their hosts. just outside the center these women were making firewood with their children. they have been here for four years. not an easy life, but they've been welcomed. sympathy said she had no intention of attempting the journey across turkey and into greece. that is likely to be because killis has opened its front doors to the syrians. so it has been nominated for the noble peace prize. they have even invited the european the european leader there, angela merkel. it has been common for turkey to be written off, lack of press freedoms, adelaide human rights violations and so on, but the contrast the way in which it is manage the refugee crisis and the kayous of the european union couldn't be any different.

what then do the authorities say to a europe of closed borders. >> translation: killis hosts more syrians than its own population. they share their cities and streets and air with syrians. it should be recognised by the e.u. and all countries in the u.n. and this is why it should be annulled warded a noble peace prize. >> reporter: of course, elsewhere there is huge resentment to the refugees the refugee crisis is a major issue in regional elections taking place in germany on sunday. german chancellor angela merkel is holding a final campaign rally. new parliaments will be elected in three sa states where a key talking point is the refugee

crisis. the right wing party alternative for germany has surged in popularity. dominic kane reports. >> reporter: this woman and her party are riding high in the polls with local elections just around the corner. with that popularity has come greater scrutiny. the alternative or afd once crated on opposing the euro. the main concern now is the influx of refugees to their country >> having taken more than one million asylum seekers and waiting for family, this will cause issues for germany on all sorts of levels in politics >> reporter: shifting their focus on to immigration has won them few friends among the political parties but it has gained them popularity with voters. before the influx of refugees started last summer, the afd was

receiving less than 5% in the opinion polls. fast forward to now and that number has more than doubled. one leading academic told me he thinks the coalition government's immigration policy is the main reason why. >> the afd has had really a good opportunity to get profile as an important and necessary part of german spectrum which gives voice to those citizens in increasing numbers who are not represented by the politics of the group. >> reporter: for now the test for the party is in the state parliament. the german federal system gives the states considerable powers and elections there matter. the eastern state is one of three to hold elections on march 13. a recent survey suggests the afd has now supplanted the main

social democratic party here, some afd supporters were keen to make at a rally. >> we know that they're not all war refugees. we're also human and we want to help, but we will not be made fools off. that's exactly what is happening. that's why we're here to support it. >> reporter: they belief afd speaks for their concerns. the question will be whether they can translate their opinion poll numbers into actual votes. dominic kane u.s. president obama has spoken at length about syria's civil war in an interview to the atlantic magazine. he elaborated on his decision no not launch a full-scale attack against the al-assad government after it was accused of using chemical weapons. he criticized some of washington's closest allies.

european countries did launch air strikes in libya to protect the residents of benefit gaz ee-- benghazi. obama also had tough words for the saudis who have been worried about issues with iran. the administration dispatched secretary of state john kerry to the region over the weekend. >> there are tangible, practical holding your hand ways that foreign leaders around the world request easily ascertain what the united states policies are >> reporter: while some think president obama's might have been too frank for someone who still has a lot of months in office, others think he might be clearing the way of action on a major foreign objective, israeli

peace >> a debate whether something could happen before the elections or after, but i think there are things the president can do in this final period of his presidency to resurrect the credibility of the two-state solution. >> reporter: whether obama was simply selling scores or under lining his months in the office, his allies will have taken notice activists in bangladesh have begun a 250 kilometer march in protest against plans for the building of a coal power plant close to a world heritage site. they're marching from the capital towards the world's largest mangrove forest. in 2010 an agreement was signed to develop the power plant. the company says it hopes to visit the country this month to
