victory for the republican ted cruz and bernie sanders in wisconsin primaries you're watching al jazeera live from doha. also coming up, one of libya's two rival governments steps down for the sake of political unity. anger on the streets of peru as thousands protest against the

presidential runner. toxic water, millions of people don't have safe drinking water in bangladesh the front runners in the democratic and republican presidential contest both suffered defeats in the latest u.s. primary in the state of wisconsin. bernie sanders picked up another win beating hillary clinton on the republican side. ted cruz won against the front runner donald trump. cruz called it a turning point in the republican presidential race. >> reporter: it was a victory for ted cruz beating donald trump in the primary. >> tonight was a bad night for hillary clinton. it was a bad night in the

democratic primary and it was an even worse night for her in the republican primary. [ cheers ] >> we are winning because we are uniting the republican party. >> reporter: the cruz campaign claims the latest victory will propel him to win future state contests that cause trump to fall short of the 1237 candidates needed to win the nomination before the convention. a convention where cruz hopes to become the party nominee to take on hillary clinton. the path to her party's pension nomination has also become more complicated for clinton. bernie sanders was the winner of the democratic contest in the mid western state. >> with our victory tonight in wisconsin, we have now won seven

out of eight of the last caucuses and primaries. [ cheers ] >> we have won almost all of them with overwhelming landslide numbers. [ cheers ] >> reporter: bernie sanders says the grass root support will propel him to win bigger upcoming contests and allow him to increase his delegate count, but the footpath favors clinton. she still has the lead in delegate support. the next contests will be a challenge for sanders given she once represented the state as a senator in the u.s. congress. what is clear from this primary is that the momentum of both the republican and democrat front runners have been blunted. ted cruz and bernie sanders saying the course of the chain has been change and it could be

a very messy path and it is expected to go right through to the july convention a professor of politics at the george washington university says the election system would favor cruz more than sanders as the contest continues. >> it is true that bernie sanders has won a number of contests, but we have to look at what type of contests these are. what he has been doing very well in and doing well among are those who are independents who are open to vote in those open primaries like wisconsin or closed contests. we see that this race by the time it moves to new york will have a very different character. new york has a closed primary. that means the democrats are the ones who will be voting not independents, and when you look tonight, even at the exit polls,

bernie sanders and secretary hillary clinton split democrats 50/50. certainly ted cruz's win tonight is a significant one, he did pose at least what we're expecting to a 15% margin that is much larger than any of the polls predicted wisconsin was going to be. i think it is also important to look he won republicans in this contest. donald trump, like senator sanders, won independence. as we move forward, these will change the character of the race and i think on the republican side we're certainly looking at a contested convention where, as on the democratic side, hillary clinton is likely to gain the delegates she is needing to win, but bernie sanders is able to stay a thorn in her side, traps

all the way through june one of the two rival governments in libya is standing aside to "prept any more bloodshedskwot. the announcement comes after the ucht n-backed unity government arrived in trip he. since 204 libya has had two competing administrations, one in tripoli backed by powerful militias and the other one in the port city of tobruk. >> reporter: the u.n. special envoy to libya is all smiles. that's because he has managed to reach the capital of trip leap to meet part of the unity government he helped form. he knows further progress won't be easy or quick. >> tripoli must become an international city where they reopen their embassies. it will take some time. we all have to push together. >> reporter: he was greeted with the news that the political group will step aside. that government is isn't the only challenger. another has refused the deal to

the libyan supreme court. the one based in to bruk has-- tobruk has refused it. politician has been tasked to head the g nchl a and the task to unite the fractured libya. he has been mostly confined to a naval base. this is the first time libyans have reasons to be optimistic after months of fighting that has reduced many cities to rubble and caused a power vacuum that is being exploited including groups by i.s.i.l. >> >> translation: we want to have a government, security and an army. we don't want militias. >> translation: we want a government of unity. we want an army, police, salaries and stability. we want a state that can protect its borders. >> reporter: these demands are a

major challenge for libya which remain split between rivalries and other armed groups russia says it will support u.n. brokered talks in syria. staffan de mistura is in moscow to meet the foreign minister. he is hoping for more negotiations ahead of the next round of talks to end the conflict. >> i must say i also want to make the point that [indistinct] we are extremely pleased on how the indications came from the liberation, which has been a symbol for the whole international community of what needs to be the beginning of freeing areas which are of international value which we've

been waiting for. that's something that what we need to acknowledge the opposition in iceland is renewing its calls for a snap general election after the resignation of the prime minister over the revelations about his and his wife's financial links. there are links to an offshore companies with big claims on iceland's banks. in other words, a big conflict of interest. >> reporter: it is as far as you can imagine from iceland to the british virgin islands, but the attempts by the prime minister here to help hide his wife's wealth there have caught up to him. this woman runs an ice-cream parlour. her sell out is called wintris, the name of the company that the prime minister and his wife established. lots of lemons >> it is very powerful and it

leaves a, what do you say? >> reporter: a sour taste in your mouth >> yes. bitter like we all feel today t we feel sad and i am ashamed, like i'm shamed to be an icelander. >> reporter: having walked out of the interview which confronted him with his part in a tax dodge had pent monday saying he wouldn't resign and then tuesday saying he would. if his coalition partners wouldn't stand by him. for now it's april standoff, but opposition groups believe he won't last until a plan of no confidence vote on thursday. >> there is no meetings in the parliament, no chamber meetings or economy meeting because people feel that the parliament cannot function in this state of crisis. we have a full pledged political crisis that needs to be solved. everybody except the prime minister himself recognised that this is doing tremendous damage to the reputation of iceland in the international context >> reporter: the protests over this reflects a sense of

betrayal. projects have restarted as the economy has picked up, yet the country's bank remain weak and government imposed capital controls mean a limit on how many people can take out of cash machines. in that context of the idea that their prime minister has been helping his wife to hide tens of millions of dollars so far away is, for many people, absolutely infuriating. so wintres has become part of the language of proficiency test here in misquoted shakespeare, on a tv in the shops and this one reads "not my frim minister"-- prime minister" thousands of people have marched against the daughter of the former leader, who is running for the presidency. protesters believe that if sympathy wins the elections, people that collaborated with her father will come back to power. he is serving a 25 years for

corruption and crimes against humanity. >> reporter: they shouted never again, remembering thousands of people killed or disappeared by security forces during the government in the 90s. >> translation: the people associate her with so many killings her father was responsible for. so much injustice. >> reporter: they remembered the level of corruption of her right hand man-- her father's right hand men, accused of bribing politicians, journalists, businessmen >> translation: we will never forget. no-one came out clean. everyone had a price tag. >> reporter: demonstrators protested against her candidacy for the presidency and they chose this date on april 5, that 24 years ago a coup was led to

disband congress intervening against the judiciary and began ruling by decree. >> reporter: her candidacy has divided a country much as her father did when he fled to japan. she is trying to distance herself from her father's legacy, but she carries the weight of her name. her supporters say critics are unfair to her. >> translation: sympathy can't be guilty for her-- sympathy can't be guilty for her father's mistake. she is young and has localities of projects to fill >> reporter: she signed an honor agreement to, among other things, respect human rights. she promised she won't use power in favor of her family, meaning that sympathy won't free her father from jail. she has not been able to gain more than 30% support.

>> translation: although she has distanced herself from some old supporters and old policies, some voters say there is absolutely no way they will vote for her. >> reporter: her greatest challenge is to create a new strategy to disassociate her from her father's legacy. as nearly 50% of voters say they will never put an fujimori back in power lots more news still to come for you, including no rain and no help. fill peeps drought crisis turns into an election issue. what's app unveils security measures to better protect messages from prying eyes. es from prying eyes.

welcome back. you're watching al jazeera. the top stories. ted cruz has defeated donald trump in the wisconsin primary. bernie sanders managed to add to his recent victories over hillary clinton but it was a much closer contest there. one of the two rival governments in libya is standing aside. it is a step to the national unity group to take poefr. iceland's prime minister has resigned over leaked documents that shows his family's link to offshore companies. he was facing a no confidence vote and mass protest calling for him to step down. the philippines experiencing one of its worst draught brought on

by el nino. the island described as one of the agricultural heartlands is suffering. farmers have been protesting over a lack of government action. three farmers were killed in demonstrations. our correspondent, there was tight security when those protests were taking place. what's going on today? >> reporter: it has to be said that the situation has changed dramatically since the weekend and those scenes of violence on friday, the large security situation, hundreds of police officers and special forces. there is no sign on any security whatsoever. it has to be said that up to four and a half thousand farmers have sought sanctuary in the ground of that methodist church

has dissipated as well. they wanted some help in the position that they have been facing in the draught, they have seen donations that the farmers have been dissipating now. there is less than a thousand here now. we're seeing a steady stream of people carriers as well as food distributed. they have a long journey to the areas that they come from. a couple of groups have told me that they had to travel at least three and a half to four and a half hours and they have a long journey back tonight several thousand farmers had been looking for some sense of sanctuary. are they receiving it? >> reporter: they have, yes. certainly here over those few days and they have been very grateful to the church authorities that have given them that sanctuary.

of those four and a half thousand, nearly three have left. there is less than a thousand here now. what really has transpired is that the civil society itself has come to the forefront to help many of the farmers. again, it has taken on a whole different term. farmers say they would not come to protest about their drought situation, they want to leave it in the hands of the politicians. what we're seeing on thursday will be a group of senators, the upper hours of the philippine law maker, coming to the city about 120 kilometers from here, and they will be on a fact-finding mission and only stay there to listen to testimony from some farmers, if they can get there, but mainly the police and authorities to see what happened here, why the situation got out of control. they won't be handing out any punishment, but certainly they will be using it as a political stick to hit the government with because the government have been very silent on helping the

normal farmer who is suffering from draught across not just this area, but croatian the country. it is up to local officials and local authorities that have been helping in this region there has been very little help. it is a bit sporadic where the help is, but this whole issue is turned into a more political debate. in the four weeks that we have leading to the presidential election thank yous. the international criminal court has declared a mistrial in the case against kenya's deputy president throwing out charges he faced of post-election violence almost a decade again. he and a radiologist were accused of crimes against humanity. the violence killed more than a thousand people and hundreds of thousands were displaced. judges of the court ruled witness interference have made a fair trial impossible.

south africa's president has survived an impeachment vote in parliament. the motion was launched after it was found he violated the konty stews. he had spent-- city city tugs. he had-- constitution. he spent 16 millions dollars to refurbish his home amnesty international says the number of executions carried out globally has more than doubled in the last year. at least 1634 people were executed last year. that's up from 1061 people in 2014. iran executed more people per capita than anywhere else and along with panning stan and saudi arabia carry out 90% of the executions. china is not included in the list because the country keeps its numbers as a state secret. although human rights group estimate thousands of people are executed there every year as

well. however, fewer countries use the death penalty. congo, fiji and surinan stopped engs cushions in the last year >> the rise of executions was down to primarily huge increases in three countries, iran, pakistan and saudi arabia. together these three countries accounted for almost 90% of all the executions that we recorded in 2015. again, excluding china the u.n. has up covered serious sanitation failures in its haiti peace-keeping mission after thousands of people died from an outbreak of cholera in 2010. they lacked basic facilities such as toilet and soap. the u.n. has refused to accept responsibility for the outbreak and claimed immunity from compensation claims. this update from the u.n. >> reporter: this internal u.n.

report is a damning kalt log of appalling sanitary practices by the u.n. peace keep years in haiti. 11% of the camps were still dumping raw assuming into the local-- raw sewerage into the environment. >> we're dealing with a variety of problems, including extremely poor sanitation infrastructure. as you see, it has taken effort to deal with that. we have tried and we have - >> reporter: isn't it poor accountability infrastructure at the u.n. as opposed to underground in haiti >> you're kind of playing a game with words there. what we're trying to do is physically tangibly improve the situation on the ground so it's better. >> reporter: new research suggests that the head lean figure of 9,200 dead in the

outgreat vastly undercounts the fatalities by, perhaps, thousands. each day amonth by this in haiti. we are aware that they're aware of their shore comings 20 million people are forced to drink arsenic-contaminated water according to a human watch rights report. efforts to clean up the supply has been hampered by corruption. >> reporter: for a lopping time this woman couldn't figure out what was wrong with here. she couldn't go to the stove unanal to stand the heat. she couldn't even be outside in the midday sun. it was years before doctors pinpointed her problem. the water she was drinking. >> translation: my parents and my husband took me to many doctors. they all said i had a skin condition only.

it wasn't until someone from an arsenic outreach came to my village that they figured out what was wrong with me. >> reporter: according to a human rights watch report published on wednesday, thousands of people suffer from arsenic-related problems that are not detected. >> reporter: doctors rely heavily on noticing skin lesions which sometimes alert them to arsenic-related diseases. the problem is most people suffering from such illnesses don't develop these lesions. the condition is not diagnosed and they don't get treatment. >> reporter: it is a forgotten tragedy. about 20 years ago arsenic in the war was a big news story home and abroad. government agencies an international donors promised to stamp out the problem. >> translation: in the old days people would drink from lakes and ponds and there was no arsenic problem. then we started to build tube wells to combat disease and that's when the arsenic became

an issue in the water. >> reporter: the solution was to build deep tube wells which reached deep groundwater beyond arsenic contaminated zones. 43,000 people continue to die every year from arsenic-related illnesses according to human rights watch. their report says a major problem is the deep tube wells are diverted from high risk areas ending up in safer zones that are closer to the homes of people with connections to politicians >> translation: i think the claims of corruption are over stated. our officials are working around the clock to identify victims in airs that need wells. >> reporter: human rights watch has called for donors to investigate where the weld they funded ended up being installed. it might be too late for this aleppoed, but she hopes there's still time to save her child from suffering the same fate what's app is encrypting its

data between users. they say it will be virtually impossible for their communications to be intercepted. >> it means that anybody who sends a text message or makes a phone call through the app can rest assured that their communications are only going to be seen or heard or read by the person who they are communicating with, or the group they're communicating with. the government won't have access, not the u.s. government or chinese government. it means criminals won't have access so it provides a greater level of protection. it also makes it harder for law enforcement to eavesdrop on those communications which, of course, is a challenge for law enforcement. it has been in the works for a long time. i'm not sure why the announcement came. it could be because of the apple

story, but my guess is it is something that they've been planning and it happen been in the wake of snowden revelation. it makes people think about security and privacy knowing that the government had eavesdropped on communications around the world. in terms of the impact. i think governments are going to be concerned. and that's for a variety of reasons. some because they want to know what activists are saying and others because they want to do something about criminals who are plotting criminal activities, or hurting children, whatever criminals do. there is a lot of controversy about this issue, but a lot of people want encryption for legitimate reasons, business deals, personal information, they may have health data acor private information about their location. it's about protecting themselves and their children as well as
