others use rubber tubes. even then not everybody is wearing them. these iraqi families probably paid hundreds of dollars a head for passage. but the boat is too small. this is how families are separated in a moment. he can only call out, look after the woman. it has been a chaotic few minutes here. the message from the e.u. from turkey and greece is these kind of voyages are futile. these people will be sent back. a handful are left on the shore. we ask why they are risking all of this, while under the new rules they have to go to a detention center. >> translator: greece doesn't want to accept us, turkey

doesn't want us. where else should we go? is it better to sink into the water with our children. >> reporter: within a few minutes a coast guard patrol has intercepted these people. this former free syrian fighter, he tells us he has been smuggling people to greece for nearly a year. he says agents like him are trying to convince reluctant customers that they still have a chance of making it into europe. >> translator: we tell them they can still get residency in greece. they think they will be sent back. >> reporter: europe is trying to close the door. wednesday was supposed to see the first official batch of syrians sent back to greece under the controversial deal. the only arrivals were those who

had been on the water matter of hours. >> translator: we were going to greece to escape the war. do you think it was a holiday? we cannot leave here. everyone treat us badly. they exploit us. >> reporter: what happens to them now is far from clear. still in the same country as those they left behind on the shore, but separated from them. the children play a warped version of a morning on the beach. a life jacket becomes a toy instead of a call for help. harry fawcett, al jazeera, turkey. there are conflicting reports on whether a ceasefire is actually holding. the two countries agreed to halt fighting after four days of fighting. the ceasefire held overnight, but the defense ministry is reporting 115 armenian violations in the past 24 hours.

turkey's president says armenia's troops need to put down their weapons. >> translator: i hope armenia will respond to the efforts to stop the armed clashes, but if it wasn't respond, this crime is armenia's fault. russia says turkey is taking sides. if you are looking for those who are taking sides, the most significant country doing that is russia. it loves to take sides. it took sides in ukraine, georgia, and now syria. at least eight iraqi soldiers have been killed in an us ill attacks. one of the two governments in libya is quote, standing aside to present more bloodshed. since 2014, libya has had two

competing administrations, the one in tripoli backed by powerful militias and the other in the port city of tobruk. >> reporter: the is all smiles because he had managed to reach tripoli. but he knows further progress won't be easy or quick. >> tripoli must become again an international city. this will take some time, but we have all to push together. >> reporter: he was greeted with the news that a tripoli-based political group will step aside. but that isn't the only challenger. the one based in tobruk has repeatedly rejected the accord. this veteran politician has been

tasked to the head gna. since he arrived he has been mostly confined to a naval base. but this is the first time libyans have reason to be optimistic after months of fighting that has reduced many cities to rubble and caused a power vacuum. >> translator: our main demand is for us to be like other countries. to have a government, security, and an army. we don't want militias. >> translator: we want a government of unity, we want an army, peace, stability. we want to protect our boarders. >> reporter: but these seemingly simple demands is a major challenge for libya which remains divided. the front runners in the

democratic and republican presidential contest both suffered defeat in the latest u.s. primary in wisconsin. bernie sanders picked up another win over hillary clinton. and on the republican side, ted cruz won against donald trump. cruz called it a turning point in the republican presidential race. >> reporter: it was a decisive victory for ted cruz in wisconsin, dpeeting front runner, donald trump in the state's primary. it was a win cruz promised would change the course of the republican race for the white house. [ applause ] >> 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 and applause ] >> we are winning because we're uniting the republican party. >> reporter: the cruz campaign

claims the latest victory will propel him to win future state contests and cause trump to fall short of the delegates needed to win the nomination before the republican convention. it's a convention where cruz hopes to become the party nominee. to take on hillary clinton. but her path has always become more complicated. bernie sanders was the winner of the democratic contest in the midwestern state. >> with our victory tonight in wisconsin, we have now won seven out of eight of the last caucuses and primaries. [ cheers and applause ] and we have won almost all of them with overwhelming landslide numbers. [ cheers and applause ]

>> reporter: sanders says his grassroots support will propel him to win bigger, up coming contests, and allow him to increase his delegate count. but the math favor clinton. she still has the lead in delegate count. the next primary will be a challenge for sanders. what is clear from this wisconsin primary is the momentum of both the republican and democratic front runners has been blunted. ted cruz and bernie sanders saying the course of the campaign has been changed, and now it's expected that these nominating contests will go right to the convention. let's hear now from clyde wilcox, a professor of government at georgetown university. >> bernie sanders has to win 56%

of the delegates from here on out. that's about what we got in wyoming. so he needs to do exactly that well in new york, new jersey, and california. he is behind in all of those states, so it looks like he will have a very steep road to climb. the republicans do not like ted cruz, but he is the one man who could maybe stop trump. it seems that trump will fall a little short of a first-ballot victory, which might make for an interesting time for newscasters. bernie sanders is winning 80, 85% of people under the age of 30. he is saying let's really shake things up. and hillary clinton is saying we have to make small changes. young people are not really in the mood for that. still ahead on al jazeera, we speak to an indeedian businessman who says he has no idea why he was named in the

front runner donald trump in the wisconsin primary. and democrat bernie sanders managed to add to his recent victories over hillary clinton but it was a much tighter contest. one of the two rival governments in libya is standing aside. it is a step forward for the national unity government to take power in tripoli. but there is still some resistance. activists in aleppo have confirmed that the only road linking the syrian city to turkey has been cut off by fighters. heavy fighting has been reported. our correspondent has this. >> reporter: achmed and his family rely heavily on food handouts, but it's barely enough. he is scared that kurdish fighters could cut off the only road out of aleppo. >> translator: god forbid if the road is closed, it would be a big problem for us.

there will be shortages in food, and people are poor, they don't have the ability to stock food. >> reporter: aleppo is syria's largest city. its center is divided. government forces control the eastern side, and the opposition controls the western side. and since the truce between the government and rebels began in late february, syrian forces backed by russian air power have advanced on rebel-held areas in the northern countryside. there is also fighting in the city's northern parts. kurdish forces known as the ypg, seen as allies of the government are making gains. the goal is to surround and completely cut off the rebel-held areas of aleppo. activists warn that up to 300,000 people could be affected. at this marketplace, the produce is abundant and fresh.

people say they are worried, yet they remain defiant. >> translator: we have everything. there is food, even [ inaudible ]. >> reporter: he relies on farming to feed his family. he says it is the best way to survive. >> translator: we have beans, spinach, whatever vegetables you can think of. we can farm and rely on animal stock if there is a siege >> reporter: fighting stil continuing and it's not clear if the kurdish forces can sustain their siege. but if they do, it will be the people of aleppo who will suffer the most. the so-called panama papers have claimed their first high-profile casualty with the resignation of iceland's prime minister. the leaks from panama based law

firm showed he owned a company with his wife, but had not declared it when the entered parliament. hundreds of india's rich and powerful have been named in the leak. the government is launching an investigation. one industrialist told us he had no why how he was implicated. >> reporter: behind these gates is the resident of one of the 500 people named in the panama papers. he is listed as a beneficial owner of a shell company set up last year. >> i don't even know this company. so let me just elaborate and tell you. when i relied giving the newspaper all of the details of my carpet holding, and my personal holding, including

dates when moneys were emitted, everything. because both are aboveboard as far as the laws of india are concerned. >> reporter: according to the investigation, there were items found as proof linking him to the company. he shows us an email from the first-named group. a corporate service provider in the isle of mann. this is part of the express newspaper team that lead the investigation. he had been correspondenting before the release. >> we are putting out those reports. now what is legal, what is illegal, and what is in between, that's for the agencies and the

[ inaudible ] to decide. >> reporter: the panama papers have evoked much attention from the public. since the report's release, the issue have been on the front pages of almost every paper daily. >> there is a big gap existing. so when these people they are taking advantage by taking their money to some other countries, then it hurts it. >> reporter: and that is a worry for this spokesman of india's ruling party in west ben gal. the prime minister and his party came to power and promises to crock down on tax evaders and punish those who try to hide wealth abroad. the panama papers come at a time when the party is trying to win over voters in five states where

they have never had a foothold before. china is stepping up pressure on north korea. beijing has banned most im ports of north korean coal and iron ore. and china buys an estimated two-thirds of the exports making beijing's cooperation essential for the sanctions to succeed. >> reporter: the trade restrictions are part of the u.n.'s tougher sanctions. and the import ban inclueses coal, iron ore, red earth. this is an important source of income for north korea. so these restrictions will hit north korea hard. but the statements comes with what some say is a loophole, it

allows the trade to continue as long as the proceeds are for the people and not the nuclear plan. what is unclear is how china plans to manage or keep track of that. china has been under significant pressure to be tougher on north korea especially after the north conducted nuclear and missile tests in the first quarter of this year. and it has supported the upundertougher sanctions, but chai that has traditionally preferred a softer approach when it comes to north korea. analysts say this is because china feels the collapse of the kim regime could lead to a flood of refugees. but this could be a sign that china is willing to change its approach when it comes to dealing with north korea. a drought in africa is causi

causing prices to rise. tania page now rights. >> reporter: in her small shop, this woman makes her bread. but things are getting more difficult. the drought is now even hitting people in the cities. the average prize of a bag of maze has risen by almost a quarter. potatoes cost 29% more, and the price of sunflower oil has soared. >> translator: if i were to increase prices, my customers will walk away. they are already complaining. they say food is expensive. they cannot afford, because people in the townships have no jobs. >> reporter: for months they have been warning parliament that this could trigger riots.

the country will have to import more food, but that is difficult too. >> we are expecting to see further increases in the next three months or so, but what is more painful is that these increases are likely to be sustained up until mid-2017. >> reporter: the world food program says up to 50 million people may be effected across the region. these kids are giving thanks for what little they have. 20 children live here at the center, but another 30 come for lunch every day, because their families can't afford to feed them. they are among the country's most vulnerable citizens. a rat has gotten into the orphanage's food store. fortunately most of the supplies are safe. >> if this continues it will be

terrible, really, terrible. because this is what the kids must eat. the kids must go to school. the kids must -- they must be fed, because some of them are under nourishes like that [ inaudible ]. >> reporter: she thinks as more families struggle, more kids will come to her for help, and one of the world's most unequal societies, it's those at the bottom who suffer the most. u.s. drugs giant pfizer has scrapped a $160 billion merge with their rival allergeshan. the u.s. is cracking down on companies moving offshores to avoid taxes. the instant messaging service what's app is encrypting the data sent between its one billion users.

it says it will be virtually impossible to crack the messages. the fbi recently dropped a case against apple over his encryption. >> ta 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 or group that they are communicating with. it means the government won't have access, not any government. it means the criminals won't have access, so it provides a greater level of protection. and it also makes it harder for law enforcement to eves drop on those communications. it has been in the works for a long time. i'm not sure why exactly today the announcement came.

my guess is it is something they have been planning, and of course it has been happening in the wake of the snowden revelations. and i think that really stimulated a lot of people to think more carefully about security and privacy, knowing that the government has eaves dropped around the world. some will just want to know what activists are says, others because they want to do something about criminals who are plotting terrorist activities, or farming children, or robbing banks, or whatever criminals do. so there is a lot of controversy about this issue, but a lot of people want encryption for business deals, personal information, they may have health data, other private information about their location, so it is also protecting themselves and their

children as well as the issues that law enforce brings up. almost half of all world heritage sites are threatened by mining and illegal logging. the wwf is listing 114 threatened sights which provide food, water, shelter, and medicine to more than 11 million people. gerald tan has the details. >> reporter: the great barrier reef in australia, the seringetti, these are some of the planet's most beautiful nations that the united nations has designated as natural world heritage sites. there are 197 of them around the world, and about 90% provide jobs and contribute to economies through tourism, recreation, and natural resources. it is estimated 11 million people depend on these sites

either for food or work, but a new report says that harmful industrial activities, including mining and oil production are posing a threat to almost half of these places. >> these are very special sites. these are very special places. not many places make it to the top list, and if the sites are threatened, can you imagine what happens to other natural places around the world, so this is indicative of a much growing pressure on many natural places that are so important not just for nature but also for our own developmental well-being. >> the reef is particularly at high risk. offshore oil drilling, mangrove clearing, and construction has damaged more than half of it. about 190,000 people rely on the reefs for fisheries and tourism.

the wwf is warning that it is not just harming the environment, but also the people that these ecosystems support. plenty of more news on our website. aljazeera.com is the address. god bless the great state of wisconsin.
