a world's 1st trial in connection to syrian state sponsored torture. while some victims of torture were among those testifying they hope the trial could set an international precedent did he spoke to one young syrian here in germany she has not seen her father since he disappeared 8 years ago witnesses say he was seized by armed men from his home in damascus. there are always fresh flowers next to ali moustafa us portrait he was forcibly disappeared in syria 8 years ago the few remaining photos of him i was daughter while father's most precious possessions just look at them a 1000 times trying to conjure up his presence the day it happened was i was away from other then living in northern syria had meant to visit her husband in the mask because they hadn't seen each other in months. or 10 minutes before she arrived she called them and said i need to stay in i'll be there in 15 so he said that i clean

the house everything is perfect and i'm just waiting for you'll. see our fists in minutes later she i have doubt she called him and he never responded. oh my. god i mean. of the day but i was so calling to neighbors armed men had come to take the most stuff away while father mother and sisters had to flee syria one week later and leave him behind they still don't know anything about what happened to him. and i actually survived by leaving syria and not getting killed. maybe i have physically survived somehow bought you cannot just get used to the fact that you lost your dad in one second you know you cannot just used to the fact get used to the fact that he just disappeared for no reason. my 1st father is one of 130000 people who have

gone missing in syria investigators believe most of them were disappeared in bashar al assad's prisons jim court has now convicted one former intelligence officer for his role in the torture of prisoners in syria another officers trial is still ongoing when the trial began wafa sultan amongst a portrait of 61 to 10 years and held a vigil in front of the courthouse. i live in mind myself and i don't mind the whole word every day that my dad was political was against the eugene he only demanded freedom justice and the state of law and for that reason has been disappeared for almost 80 years now and this is not acceptable i'm not going to be silent about that today we're often feels at home in berlin though she could see herself eventually returning to syria and rebuilding the country in the meantime it's important for her to be in germany at this is storage moment i think this is

the hope of many syrians in very many we are working our best to be accepted part of the decision making regarding syria because you cannot just discuss and decide anything about us without us. hopes to reunite with the father one day until then surely mind the world of the fate of syria has disappeared. well let's get more on the trial in copeland's now. on highness and following proceedings for us there but as we said this is the 1st international trial of state torture conducted by the assad regime in syria tell us about the verdict here and what exactly the defendant has been accused. of the verdict is the accused has been found guilty of crimes against humanity because he has supported the depreciation of liberty and taught in at least the cases but. this

case is not just about a this was made clear by the ruling of actually the ruling is not just over i had to step out here but she took at great length she talked about a system of torture in syria as a system of oppression systems that bashar al assad had installed to keep his iron grip on the country and actually that's what's on trial here today and copeland's what was he sentenced for and for how long the sentence for yet is 4 and a half years in prison and that means that even though he is being in prison during the trial and pretrial in pretrial treason he will stay in prison and will not walk as a free man out of his called room with his a lot of people been wondering why this trial on state sponsored torture in syria

is taking place in germany why is that. well obviously the best place for a trial like that would be syria itself but that's not possible because so tough a trace is the main perpetrators all still in charge that. comes into play something that we call. international criminal law and universal jurisdiction because of that's german prosecutors and german cults can prosecute crimes even though they haven't been committed in germany and even doing these it germans are involved either as victims or as close. as people who do those crimes. fun high in reporting in copeland's for us thank you. now to a verdict in another closely watched court case here in germany and a tourist iraqi preacher known as abu allah has been found guilty of supporting

terrorism and being a member of a terrorist organization he was viewed as the leader of the so-called islamic state here in germany. was accused of radicalizing and recruiting young people in germany and helping them to travel to iraq in syria has been sentenced to 10 and a half years in prison the conviction brings an end to a costly high security trial. our political correspondent julia so delhi has been following the latest on this story for us hi julia so how significant is this case . it is an important case and it has been an important trial as you've said it was seen as the point of reference for the islamic state in germany and a very important recruiter across europe he was sentenced to 10 and a half years in prison which is quite an important sentencing the prosecution had asked for 11 and a half years and he has been charged and found guilty of being

a member of a terrorist organization of aiding the organization of violent acts and of funding terrorism and his acts have had serious consequences. people that he has recruited and radicalized here in germany have traveled to iraq and syria including 2 twins who traveled to iraq and killed many people in a suicide attack and the case has also been linked with a codefendant. was said to have house he is the terrorists who killed 12 people in attacks against a christmas market in berlin in 2006 although there has been no direct connection with. have been part of his network at least this is been a pretty complex trial julie it started 3 and a half years ago i mean how difficult was it to gather evidence against. it has

been hard to find concrete evidence especially looking at the. toughest accusations against and the court case has relied in terms of evidence mostly on the testimony of 2 informants one is a member of the security services. was imbedded in the network and collected evidence over the years and another informant is a former radicalized person who was radicalized and who traveled to syria and once he came back to germany he decided to talk to the security forces and tell what the network created by was all about what does this case tell us about the islamists here in germany i mean how much of a threat does the. authorities say that the situation is still serious there's still a serious threat of islamic terrorism but it has changed compared to the years to tell that 20122016 we now don't anymore see

a clear and widely accepted leader of islamist factions here in germany and the situation is evolving now the major threat is given by individuals who might be inspired by terrorist ideologies but there is not a strong clear network here in germany and the situation has definitely changed since 2016 also because of the fall of the so-called islamic state in syria and iraq and because of the action of authorities here in germany pursuing such groups are political correspondent julia so delhi thank you now to some other headlines from around the world joe biden has held his 1st bilateral meeting as u.s. president with canadian prime minister justin trudeau in the virtual meeting the 2 leaders discussed their mutual policy goals around china and climate change they pledged to work towards achieving net 0 emissions by 2050. we're now and british

naturalist david attenborough has issued another impassioned plea to world leaders to take immediate united action on climate change speaking at a virtual meeting of the un security council and burress said continuing on our current path would lead to the collapse of the natural world and the breakdown of civilization gonna has become the 1st country to receive vaccines through the un backed kovacs initiative 600000 doses of the astra zeneca vaccine have arrived in opera it is the 1st batch of $2300000000.00 vaccines expected to be delivered to low and middle income countries by the end of the year. and asked for an astra zeneca will reportedly deliver less than half of the vaccine that promised the european union in the 2nd quarter of this year the drug maker is supposed to provide $180000000.00 doses to the e.u. by the end of june it has already missed its 1st quarter commitments due to production issues. for the 1st time german authorities have given approval to

rapid covert 1000 tests for home use 3 products have been cleared by germany's medicines regulator until now rapid tests could only be carried out by trained professionals in the country the health minister hopes the kids will play a central role in curbing the pandemic as lock down restrictions are. he says more home test kits will be approved next week. could the mass testing planned for germany has already been rolled out in austria did not be as funny for char reports from vienna where rapid and tests are freely available and even compulsory for school students the opera house is one of the landmarks but unfortunately the only going on the locals are no longer coming here to enjoy a performance what they want is a rapid and teaching test and this is for example the spruce over there which by the way used to be a traditional viennese suit stand. i need to get tested to.

thank you very much well needless to say this was very uncomfortable but very quick to within minutes i will have my result this cost me sooty 9 euro spot there are hundreds of pharmacy in austria where you can get tested for free but there you will need to wait a bit longer for the result and there are a lot of people here who are willing to get tested to get this quick and fijian test done in order to go to the hairdresser or to go to school because there are schools here in austria it's required twice a week to present such an antigen test a negative called the test result of course to be able to participate at school currently $1000000.00 tests are carried out each week in all stria one of the highest rates in the world has the government and the government hoops the more acceptable to be called to get tested the sooner the economy will be able to get

back and to reopen. a new report is calling for u.n. sanctions against sri lanka's former top generals for war crimes during the country's civil war for almost 3 decades tigers separatists fought for an independent state for the ethnic minority more than 100000 people were killed in the war many of them civilians thousands more disappeared. this is the number of days these mothers have been protesting for 4 years they've stood on the side of the road in the town of junia in the north of sri lanka. the women want to know where the children and husbands are they've been missing since the end of the civil war in 2009. jail when he took us he poli has also been here every day for 4 years she's looking for her daughter. that thought about it would that we need each other my suffering is also felt by these other mothers because of that i keep on functioning that it not only for my child but for only children and husbands who

went missing we have to find out what happened to our children that all these mothers believe that their children and loved ones will return that they can't lose their hope. 52 year old says she recognized her daughter in this photo from 2015 it apparently shows the girl standing next to form a sri lankan president much upon a series saina. signifies a spurt her tone in the mother's protest. the family belongs to the tamil minority during the last days of the civil war they were forced to leave her home and were taken to a camp run by sri lanka's secret service and interrogators on the way to go on the ticker is a polite says her daughter was kidnapped by whom is unclear. shortly before the end of the civil war in 2009 the sri lankan army kind tamil territory the soldiers were looking for fighters from the tamil tiger liberation organization or l.t.d. who were fighting for independence according to the un both warring parties committed serious war crimes up to 15000 tamils are officially messick that the

united nations believes the number to be much higher it has been impossible for this family to find peace since their eldest child disappeared they have been to the police time and again and even called on the un refugee agency and the un human rights commission to get involved but in vain philibert about it it's very difficult now that my wife stays a lot of money at the protest site but i'm with her and thought all the time about them and i keep telling my wife to bring out daughter home. or i'm convinced that my daughter is still a life or your. protest spicer lanka's tunnels are growing. thousands took to the streets for 3 days in early february demanding the government clarify what happened to the countless mr sri lanka's current president got a buyer rajapaksa declared all missing persons to see east and 2020 including the

daughter of jail will need to supply rajapakse that was the defense minister during the civil war the un commissioner for human rights lays the blame for alleged atrocities committed during that war on rajapaksa current army chief. the women simply want to know what happened to their children so far no sri lankan government has offered to help them. let's speak more about the story now with another on the sheaf the u.n. deputy high commissioner for human rights must honestly say you so much for joining us. let's talk 1st of all about the measures that you are seeking in sri lanka what sort of sanctions are you calling for and what are they supposed to achieve. well 1st of all i mean i think the big worry is that these and by nations with unity without any sign of dress poorer the victims so we are calling for 1st of all an

enhanced one a training and strong preventive action by the international community i think this is essential for us to make sure that we don't slip further into war and more violations we just heard from this story the right to truth and justice for the victims i think this failure to deal with the past has had a devastating impact on all the communities and so we want the international community to listen and need the early warning signs. time for international action to ensure this justice investigations and prosecution in their national courts i think is a is one option certainly under the accepted principles of extraterritorial universal jurisdiction and targeted sanctions what we've seen before acid freezes travel against credibly and perpetrators are going to be important aspects i'm wondering what were sponsor got you're anticipating here from the sri lankan government

because it has maintained that it is not complicit in any disappearances or war crimes and that it doesn't recognize any foreign judges so what impact could these measures actually have. well i mean we have a very transparent relationship we published our report which will be discussed this afternoon when the council the high commissioner will present the report and then we will open it up to it if there are active discussion and debate we're having gauge with the government they have read the report they have made their comments we've had discussions and i think we need to have a continued open dialogue as we do both in colombo and from here. from new york as when i think we believe that unless we see specific action we have really many wearing trance over the past year or so what the government says and what it does need to be consistent there's been an increasing militarization of many governmental functions more intimidation of civil society very rapidly

shrinking civic space many constitutional safeguards inversed political obstruction of accountability and the use of anti terrorism laws i think we're looking to them things and there are many facts on the ground that speak to the inability or unwillingness to move forward if we talk about the violations that you're tracing back to the conflict the war ended more than a decade ago why do you think it has taken so long to call out human rights abusers in sri lanka. well i mean i think this is always a complicated issue we need to have the facts we need to establish we need to have access i think to the many narratives that are going on and i think we believe that's one stage that we really were making progress but i think these past couple of years have been very complicated for us particularly this last year and i think that demonstrates that inability and unwillingness of the government at this stage to deal with the past to advance accountability in any meaningful way means that we

have to consider international action the tool to ensure justice for international crimes we saw the emotional story of families looking for answers about their disappeared loved ones are you hopeful that there really is an opportunity here for them to find justice well i mean i think that's what this house is all about and in the human rights council is really trying to underscore that while if there is justice international human rights for him are very unlawful think if we can't we have drawn up many plans we have many prescriptions we know how we can make the situation better but it needs to start with owning up to what happened. ending this overview and punitive and really making this accountability stick where it needs to have to leave it there not at all now she's un deputy commissioner for human rights thank you very much for joining us. thank you for having me. now

of opposition activists in 2011. coming up next our environment show eco africa takes us from cape town to us about to look at urbanization and efforts to make cities more sustainable way to. obtain. some of.

growing fast more and more people are leaving the culture aside in search of opportunity is now things can get a little crowded at times and that puts a strain on the environment today we're going to look at where the problems lie and which challenges need to be mustered there are just some of what's coming up. what to do when the world becomes because you can't tell 6 to a drought by diversifying its water supply. what happens to them barmaids as more people move into the city we hear from the united nations agency you inhabitants. and from got bitch to go do you think then capital is using the bone to try to generate power. from. the movement of people is the driving force behind up in isolation most people move to the sea to in the hope

of finding a better life they may be fleeing the effects of climate change or persecution all sittin up better place to implement durante is what most people living in the cities also mean so grits a strain on the environment in those areas will begin with our eco check to bring you some facts and figures. great is eating into green more and more land just being covered in concrete and asphalt urban areas currently occupied some 2 percent of the world's surface the landmass of russia and brazil combined. un studies predict cities will take up twice as much space by 2050. if population growth stays at the current rate it will have dire consequences for all more than half of us already live in urban areas by 2050 that's expected to be true of 70 percent of the world's population.

cities are spreading outwards in asia and africa in particular more and more prime arable land to spain developed by the end of this decade will see the loss of an area as big as germany. the steep rise in migration to cities is also impacting living conditions more shanty towns are springing up without proper sanitation or electricity. traffic volumes and c o 2 emissions are increasing and the amount of waste to. some 2000000000 tons of garbage are produced world wide annually by 2050 that amount is projected to double. global warming is fuelling extreme weather events the pressure on urban ecosystems is growing. increasingly people are realizing that

cities have to be made greener enter more sustainable in megacities urban farming is beginning to take off along with rooftop and vertical gardening. citizens are doing their bit cleaning up rivers and recycling plastic. and in industrialized nations cities are turning to intelligent traffic systems and sustainable mobility. c o 2 emissions could drop 30 percent in cities if more cars were shared for example but even then the environmental impact of continued urbanization will present challenges for the leaders of the africa's rapidly growing towns and cities. something needs to be done for sure many cities and collaborations already feeling the effects the impact of climate change is especially noticeable in south africa with heavy rainfall in winter stream heatwaves the rest of the year.

that is right crease in $28.00 kept down almost reached day 0 when the authorities would have been forced to tunnel the tops during the long dry period to prevent any repeat of that scenario the city is now investing heavily in water management. and some pleads the construction wonks and flew swing the west water treatment facility on the outskirts of camp town is currently being upgraded financed through in on by the german development bank for some fleece the average is long over due the form on top of the wish to water is a clear sign that the plant is struggling currently the plant is designed to treat 72000000 liters of water a day. flow into the plant is on average about 90 maybe you can see that the prong is overloaded in terms of the amount of flow that's conceiving. flashback to 2018

due to a severe drought kept on dams had run dry residents queued to stock up on drinking water day 0 was looming through strict last minute water restrictions kept on escaped the catastrophe. for city councillors sonthi limburg the water crisis was a learning experience. he did learn very important lessons from the drought one of the key this is the need for us to not be entirely dependent on surface water from grain pulling out there because there's a risk of. rainfall patterns remaining very low and we have seen this in the case for the last 5 winters and so we do that in business area and critical thing to diversify food supply and this is one mechanism in which we will waste water through the grid some fleets will be able to treat an additional 18000000 liters of

once water the end product can be used for multiple purposes we have pro quality that will come out of this won't be portable but it will be to us in the standard we can we use for industrial purposes can be used for for your guys and purposes future droughts in a fast growing population are major challenges for the water supply in kept on and surrounds especially in informal settlements poor water infrastructure ports the health of residents a triscuit so number one song see is the community leader of the language settlement contaminated water that is running through the streets is a big problem here at the end of the day all this water you see it off should treat a storm water pipe storm water power shoot straight to believe are very by fits the dam where we get our drinking water you know so it means municipalities should do as much to clean the environment why and where

a solution or community not to get or get sick you know. only a few kilometers down the hill scientists are trying to solve some of the issues that's the water had brought such as test natural processes to treat quantum you need to draw on of from the informal settlement what the experts kevin winter initiated the research site. we're really not putting enough resources into our wastewater treatment works into our water provision and into our drainage because the drainage is where the vectors for disease all started to move and so here's one example where we actually intercepting some of that water from what is effectively drainage somewhat for the downstream and cleaning that water up and using that water safely then to irrigate gardens stones and couple in sources such as peach pipes actors bio filters and clean the water of bacteria nutrients and heavy metals these nature best solutions require space but present

a useful addition to conventional treatment plants kept on has learned the hard way only by investing in its water infrastructure can the city be feed for the future the upward of some fleet is should do to be finished by 2023. but a lot more is needed to keep our biggest cities for the future they native nations human settlements program walks for more sustainable and and development so what does that mean for me and how could it change our lives if africa met we all must figure from the regional office. wanting. to see you. but up a trend of. today point to 20 we are talking about 6 to 600000000 people

living in cities which got to 40 percent of the population and by 2035 with 50 percent of population leaving urban settings look at. sub-saharan 54 percent of population leaving informal settlements water sanitation green energy and really a preschool. the deficit in africa in time of masters billions of dollars yet you have to do it if you want to keep those people in this particular area that the major question today if you facing just jealous of increased population important for us to see step out of the west how africa and cities can be nice climate and every month issues for now. it's only. you how do you even buy something and i try to buy something which is

jobs have to step basic infrastructure if you don't have you to where we are in the village we're going to do there people are looking for better jobs and better employment they're also looking for access to basic set this is climate change of course what happened in mozambique really pushed people to go to the cities of course because they're not safe and this is happening regrettably now every year so what they can do there but also you have conflict pushing people to come to cities look at what's happening decide region people are fleeing from reality to come to the city because that's where they can find peace. i'm turning to authority you are overloading your cities. those efforts let's take it to other cities and bring jobs and opportunity for people to be there instead of just concentrating on one city's you heard about this program if you can have it on public space and green which is more about you know allowing cities to have a such a consideration to the green and trees when scum you know to planning but also

allow people to get out houses and get access to those green area will help assist them with hope for social reasons in term of integration and social cohesion the upper teens and fusses morten so going to cities before entering a balance but also to loosen the pressure on big cities so that people who have access you know to basic services they assist the water sanitation health system schools where they are instead of needing to compete cities thank you very much. do you know the feeling of pain in the middle of the city and he just becomes unbearable with not even a breath of fresh air to cool to dell is because so cold heat islands build up between the buildings and it's not a problem of city life in the era of climate change let's look at what happens.

urban heating is the name given to the so called heat island effect. temperatures in towns and cities rise more sharply than in the surrounding areas because of the density of streets and buildings and the many people cars in trains all of which produce. spread over the year the mean air temperature in an urban areas is around $1.00 to $3.00 degrees celsius warmer than the areas outside them or large green spaces within them. on top of this town in city centers often cool down far less at night because the building density doesn't allow cool air to move around the city. on hot summer nights without a breeze the temperature difference between the city and its surroundings can be more than 10 degrees celsius. so what to do above the. conditioning is not an eco friendly solution we all know but there are

a number of sustainable ways in which towns can prepare for extreme weather a gem the steps taken to protect cities both from extreme heat and for with the help of nature. these young trees fresh from the mystery are being planted in a new residential neighborhood complex and handbag the leaves on some wonderfully green and french especially when compared to these beach settings. the space alder is a hybrid species bred from japanese and caucasian alder with many beneficial characteristics than an athlon evans says when it gets hot the poorest in their leaves close to retain valuable moisture. we haven't planted many of the spades out there yet it's new here a climate change tree a city tree of the future. we still have to see how they fare in urban settings my suspicion is they're far superior to native species. climate change is playing

havoc with cities around the world. one reason many cities can't deal well with heavy rain or floods is that so much city surface is covered by concrete and water concept into the ground. environmental scientists complained that this ceiling effect means half of all rainfall is lost compared to woodlands and meadows and not available to people all nature. rain water that's channeled straight into drains and carried away is gone it can evaporate and it's removed from the natural water cycle effect evaporation cools the air and we feel that has dogs as you can all the sealed surfaces heat up a lot and stay hot if there's no cooling effect from of operations that's one reason we get urban heat islands and alternative approach can be found in southern belle them in a neighborhood where sponge city water managed.
