where it is only with the siege and the strategic areas of taiz that caused a complete fall. >> reporter: forces backed by air strikes from the saudi arabia led coalition broke through houthi and opened up a key supply routes. >> hundreds of fighters who were - troops allied with the houthis switched sides and this was the reason why taiz was able to fall into the hands of government forces so quickly. houthis are trying to find answers of why this happened. >> reporter: desperately needed medical supplies as well as food and heating oil may now be delivered. hospitals have struggled for months to treat the sick and injured. in november forces fought to

therefore, our priorities are different and it leads to differences of opinion. for the lebanese it is a very serious problem because lebanon can only function on the consensus of the factions in the company. they've done pretty well in the last couple of years having a consensus on how to confront the challenges of al-qaeda and d.a.e.s.h. on their border and the army has functioned well. by putting pressure on hezbollah, you're putting pressure on the political system and driving a wedge between the various groups. will they hold together or put apart into competing factions more so russian air strikes have been blamed for the death of several, including 10 in aleppo, on friday. there is a video showing the aftermath of the strikes when a bus in homs had been hit. i.s.i.l. and al-nusra are not

part of the cease of hostilities. while the ceasefire is in place, demonstrators in syria protested against the bashar al-assad government. marches were held across the country in at least 15 cities including azaz where people were chanting slogans against the government. in a small town protesters did you say erupted the demonstration-- disrupted the demonstration. aid groups say countries including russia and the u.s. are undermining their own commitments by sporting opposite sides in the civil war. >> reporter: it is a grim milestone, almost five years since the start of syria's civil war and the new report by aid agencies, including oxfam, action aid, save the children and several syrian charities says the past year has been the

worst yet. the report entitled "fuelling the fireskwoets, that's some that 50,000 people have lost their lives in the last 12 months with almost a million civilians forced flee their homes. 200,000 of those home were partly or completely destroyed in 2015. a millionian and a half people are in need of aid and 400,000 children no longer in school because of the violence. it is noted there is pressure. u.n. security council resolutions says have consistently been flouted by parties to the conflict and their international backers, including permanent members of the u.n. sc have actively added fuel to the fire. the report highlights how russia's air campaign since september last year has damaged

civilian infrastructure while reportedly causing thousands of civilian casualties. bombing by the u.s.-led coalition is similarly noted to have caused deaths and damage to civilian areas and the international powers are accused of supplying weapons to opposing forces on the ground. the report notes that a partial cessation of hostilities has resulted in fewer civilian casualties and greater humanitarian access to besieged areas. however, all parties including governments that sit on the u.n. security council bear direct responsibility for the war in syria. jonah hull u.s. presidential hopeful donald trump was forced to call off his rally in chicago on friday night. it came after clashes. one person was arrested. >> reporter: while people protesting against republican

presidential donald trump lined the side walks outside the university of illinois in chicago pavillion, it didn't take long for things to get heated inside. the crowd and to be split about 60% donald trump supporters and 40% opponents. just as the rally was supposed to start, the trump cancelled it >> after meeting are law enforcement has determined that for the safety of all around here, tonight's 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 contingent of police eventually came in and cleared the arena but the battles moved outside. some of the thousands who were inside the arena clashed with some of the thousands of people

outside and with police. 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 what's 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 have 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 faculty and staff at the university of illinois at chicago had petitioned school administratorors to cancel the rally. they thought it would provide a dangerous environment for students. when it was all over supporters were disappointed and opposers

were happy. >> it was a good result. >> i am disappointed, but at the end of the day i'm still voting for him. nothing has changed former u.s. first lady nancy reagan has been laid to rest. nearly a thousand people attended her funeral in california. michelle obama and hillary clinton were there. reagan has been called one of the most influential first ladies in u.s. history. she died on sunday at the age of 94. lots more to come including we meet the palestinian teacher who has been nominated for the global teacher of the year award. the hike in power tariffs in nigeria despite powers cuts. ers cuts.

allegations of sexual abuse and exploitation as well as to all member states and to u.n. bodies to ensure that these investigations are carried out thoroughly prompting and impartially the greek government plans to clean out a makeshift refugee camp at the macedonia border in two weeks. on friday tensions in the over crowded camp spilled over as people justled for food aid refugees from afghanistan are part of the current human influx into europe all searching forking a better life, but for or fan children and the journey of being risk of being deported can be terrifying. >> reporter: it is a moment of respite in a life otherwise filled in hardship, loneliliness and uncertainty. teenagers who dare to dream about a fresh start far away in europe.

>> reporter: no news at all? >> no. >> reporter: like 17-year-old who left afghanistan with his parents, smugged his way to the shores of police >> the smugglers ordered me to bury my hands in the snow for five hours. i have not seen my family since. i don't know how to find them >> reporter: he is receiving medical care in the camp. unable to move forward as appear gangs are no longer welcome on the balkan route. 16-year-old is in the same situation. he is an orphan who first worked in iran as a janitor. >> translation: they were trying to deport me because i did not have a passport because i left. i want to be in a place with no weapons where i feel safe. i borrowed money from my friends. now i'm so sad to be stek here. >> reporter: along the way he became friends and they travelled together, picking up

clothes left by other refugees and hoping to go undetected. they relied on food left by compassionate people along the trail, but some of their friends didn't make it. >> translation: there were two other teenagers were us. the smugglers wanted more money. they removed their money, but they still did not have enough, so they were indicated napped and-- kidnapped and taken away. i don't know where they are. the camp here is teaming with unaccompanied children. many say there are 18 fearing they could end up in a shelter for minors. other claim they're travelling with relatives so they go unacted for and unprotected. every day there's an account of how many are still in the camp because despite the border being closed and being secured, people here want to reach their designation, so some take their chance at crossing the borderline. >> reporter: it is what others are considering. for $1800 they're promised safe

passage all the way to germany. it will mean more deaths and more suffering. waseem is over whelmed by a sense of loss. at 17 he has little to live for. >> 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 only increasing their vulnerability and the real risk of them ending in the wrong hands north korea says its military is ready for a pre-emptive attack against the south. the announcement is in response to joint military drills involving the u.s. and south korea. >> reporter: this exercise is a show of force that is always meant to impress. the u.s. say it is

non-provocative. they've told the north koreans what is taking place here. they say it adds to the stability of the region and does not undermine it. from the north koreans point of view, though, they suspect this is a prelude for an invasion, used as a cover for a build-up of forces. those are not helped by the fact that the u.s. contingent is larger than every, 17,000 u.s. forces taking part and working alongside 300,000 of south koreans. we have had the nuclear weapons test this year and last month the long-range rocket launch. we have the punitive sanctions imposed by the u.n. and south korea, meaning that the relationship between the south and north is about the worst it can get a 250 kilometer march is

taking place in bangladesh. they want the government to scrap its plans for a power plant near a heritage listed mangrove forest. the company says it will visit the country this month to discuss the issues people have marched to protest against election board barring the rival after they say his party failed to comply with reck legislations. brazil's president says an arrest for - an order for the arrest of her predecessor has no legal basis. he is wanted on money laundering charges related to a luxury beach front apartment he owns.

he denies the charges saying they're politically motivated. the president has also been under scrutiny over her 2014 campaign. >> translation: the demand that former president be remanded in custody went too far. there is absolutely no basis for the request. all legal experts agree. the gesture goes beyond common sense. it is an act of injustice. it is absurd and our country can't watch this being carried out for the leader responsible for important changes in the country cuba has signed an historic deal with the european union normalizing relations. the chief met cuban president after two years of negotiations. the e.u. is cuba's second biggest trading partner despite differences over political reform and human rights issues. nigerians will soon be facing higher electricity costs as

providers say it is the only way to improve power supply, but consumers do not agree. >> reporter: this man is very unhappy at the 6 56% rise in his electricity bill. he relies heavily on having a steady power supply for his worksho workshop. >> we will refuse to pay our bill. how can it increase. it is not steady. >> reporter: electricity providers say the price rise will generate important revenue to invest in much needed improvements >> no-one wants to pay more. we understand that, but the reality is there have been decades of under investment and we need to get the supply chain healthy and you can only do that when the revenues are there. >> reporter: the government recently privatized the

electricity industry to try and solve the power shortage. in a country of more than 170 million people only 6 million customers are on the national grid. the industry regulators say they were worse off under the old tariffs >> >> if we were with old tariff, we would have a fixed charge, without the protections that the new tariff offers. we will also be staying with the potential for increased amounts. >> reporter: the amount that is being stolen is another problem that is driving the applies increase. electricity providers are taking action. hundreds of thousand of so-called smart meters are being installed. electricity distribution companies say the technology will be able to stop customers illegally siphoning off power. the effects of under investment, mismanagement and corruption may

take years to wear off so providers can meet demands. one part which is close to the capital never had electricity >> we feel very bad and we feel that we are not human because there is no electricity. we are not in ward. >> reporter: they hope they will get connected to electricity smi soon, but 100 million dollars of investment is needed to meet the demand country wide a palestinian teacher has been short listed for the global teacher of the year award. it is given to exceptional teachers who have made outstanding contributions. we met one of the finest. she tells her story in her own words. >> translation: i'm a second grade teacher. i had a personal experience with

my children due to the surrounding violence. it affected their behaviour and achievements, but by playing games i was able to get them out of the shock. the dominant theme is violence through what they see. playing games makes them happy. happiness that they miss because of the israeli occupation. in my class i make sure that the children are happy. they play, have fun, and learn. through games i was able to change their attitudes and as a result their academic achievements. having a palestinian teacher among the 10 finalists for the global teacher price proves that we can compete, compel our methods and tools, build palestine. we can build our state. i focus on children with special

needs. they are marginalised mainly because of the classes. they need special education and i'm confident they would be creative if they were given enough potential for decades scientists have been debating what causes extreme weather events. now a team in the u.s. says it has developed new techniques that can link human activity to droughts and cyclones. it is offering alternative ways to predict them. >> reporter: these are plants enclosing the north at the end of a long and unexpectedly hot summer. they're suffering under el nino and so millions would welcome new science to help them know when floods or droughts is likely. a new branch here that seeks to link human activity to individual events.

>> it moves us forward in our understanding so that we can start to predict events months and maybe years in advance. until now scientists have compared models to try and work out what is going on. is human activity really changing the weather or are we just looking at natural 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 day here at the end of one of the hottest summers anyone can remember with temperatures through the roof. who how much of that is attributable to climate change. an increase in greenhouse emissions and other issues. it is linking different scientific design repliess which establishes human contributions to extreme weather with absolute precision. it's being referred to the

journey general report that links smoking to cancer. >> better climate models could help, better understanding of the science orificics could help. better use of objectional data sets and records could all help on that. so that sort of on the science side. on what would a person, let's say, who is responsible for safety or for the welfare of people, 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 limiting emissions. this seeks to enhance those a 16th century church has resurfaced in mexico.
