syria's government aid it will attend talks to end the war, but it will only wait 24 hours. if the opposition doesn't show up. >> and we visit the turkish border town nominated for a nobel peace prize after opening its doors to syrians fleeing the conflict. hello there, i'm jonah hull. this is al jazeera live from london. also coming up. celebrations as the yemeni government enter taiz partially breaking the year-long siege of

the city. scuffles between supporters and protesters force donald trump to call off a rally in chicago. >> and computer 3, human 0 in a landmark moment for artificial intelligence. syria's government has confirmed it will take part in talks to end the war which are due to start in geneva on monday, but warned they will wait only 24 hours for the opposition to turn up. they ruled out discussion of presidential elections and were critical of envoys who said he wanted a vote to take place in 18 month's time. we have the latest now from geneva. >> both main sides now say they're coming to geneva for the

talks. the confirmation for the government coming from the deputy prime minister and foreign minister. he made it clear that the role for president assad was not up for discussion. >> we are adamant on holding the integrity and sovereignty of syria as one state. at least this is what has been reiterated by the international documents. including those who would resolve the situation in syria. >> those comments have angered the opposition. they've made it clear that there should be no pre-conditions for these talks. the u.n. special envoy in an interview with al jazeera said he hopes to get substantive issues on day one. >> we can say that when we started talks in earnest, with

substantive talks on the 14th, we'll be able to at least tell everyone that this is happening, therefore, one is not enough, and we need to push further. and, two, now we can concentrate on the real agenda. what is it? the political process. what is that? well, it is a new governance that will be completely different from what they have at the moment. second, a new constitution, not the old approach, and three, new elections. with u.n. supervision. >> so the stage is set for an important day on monday. the first day of this round of talks and they're going to discuss the crunch issues, the

future governance of syria. >> now, a member of the syrian national coalition cautions that no one should get ahead of themselves. >> talking about elections is premature. they're starting for a transition of power to a transition of governing bodies. this is going to organize and arrange for a new constitution where we can establish a cease-fire and the syrian people, who can come back and civil education. so it's pre-ma sure now to talk about election. what we should talk about is the transitioning governor body, and this will organization electio elections. >> on the ground in syria government forces have attacked the city.

they're trying to advance on areas on opposite significance control. tha city has been nominated for a nobel peace prize and said that europe should look to the town as an example as it deals with the ongoing refugee crisis. we have this report. >> on the hills over looking the turkish border, just a few kilometers to the north is the town kilis which serves as an example of what can be done to help outside of syria if the will is there. the 90,000 who live here have been joined by 120,000 syrians. they set up businesses and work

together with their hosts. just outside of the center these women were making firewood with their children. they've been here for four years. not an easy life, but, said this woman, they've been welcomed. she had no intention of attempting the journey across turkey and into greece. that's likely to be because kilis has opened its front doors to the syrians. so they've been nominated for the nobel peace prize. they believe their efforts are so deserving they've invited the european leader they admire the most, german chancellor angela merkel, to come and visit. >> the contrast between the way turkey is managing the refugee crisis and the chaos of the european union could not really be any greater. frankly, it's hard to think of a single european town or city that could be nominated for the

nobel peace price in the way that kilis has been. >> what do the authorities say to an europe of increasingly closed borders? >> kilis hosts more syrian than it's own populations. citizens share their city, their streets, even their air with syrians. we believe the example of kilis should be recognized by the e.u. and all countries in the united nations. this is why kilis should be awarded the nobel peace prize. elsewhere in turkey there is huge resentment against the refugees, but not in kilis. laurence lee, al jazeera, southern turkey. >> government forces in yemen say they've recaptured parts of taiz which has been under siege by houthi rebels for almost a year. the city lies south of sanaa,

which is also under houthi control. they managed to take control of key areas south and west of the city with the backing of saudi coalition strikes. hashem ahelbarra reports now. >> troops loyal to president abd rabbuh mansur hadi break through houthi lines in taiz, partially breaking a seize on the yemen's third largest city. they can now send in humanitarian aid, and for the government the latest gain is the latest development in the push to capture the capital of sanaa. >> the siege of taiz was broken. this is a big issue. the wheels have started to roll. it might seem slow but efforts are huge. >> but the fight to control taiz is far from over. these are houthi fighters trying to hold ground in the stronghold in eastern taiz.

but despite the heavy fighting and gains made by government forces, the houthis remain defianc defiant. >> we will destroy them and we'll win the fight. >> this is a film of houthi fighters killed trying to defend taiz. ththe houthis were hoping to expand their presence in yemen and consolidate their grip on power. these are houthi fighters trying to repel a government offensive in the oil an- and gas-rich province. they try to move north to capture the capital. and if they do that, the houthis

might lose the water. >> republican presidential hopeful donald trump insists the rally in cincinnati, ohio, will take place on sunday. that's despite claims by local organizers that it had-canceled. it was confirmed on trump's twitter feed in which he wrote, the rally is on, love you, ohio. and it comes after a campaign event in chicago was abandoned before it could even start on friday. violence erupted between his supporters and hundreds of protesters that later spilled on to the streets at the university of chicago. and speaking now in dayton, ohio a few minutes ago, donald trump had this to say. >> it was thousands of people, and unfortunately, we were not able to let a lot of them know don't go, we would have had a problem like you wouldn't

believe. just like big nick over here, they would have wiped him out, and that would not have been good. >> let's go to alan fish who are joins us from washington, d.c. alan, donald trump back on the campaign trail in dayton, ohio. he has come under a lot of criticism both from his own opponents in the republican primary and on also from the other side of the ail. is it fair to say that he has sown the seeds for this kind of violence? >> in ohio, john kasich, and marco rubio in florida. they say he has set a tone, which is allowed this violence to failure relinquish. his democratic opponents are standing away from this for the time being, but donald trump has doubled down and said look, we're not causing this problem. it is people who are coming here to protest our first health right, and the right to free

speech will not be squashed. when asked to tell his followers to tone it down, he said, when others are told that, then we'll do the same thing. this is typical trump. he's not backing down and insisting that his supporters are good people. but we've seen violence at his events. we've seen protesters attacked at this event, and the events in chicago showed that there were enough protesters getting into that event that it could have turned very nasty if that event has gone ahead. and tomorrow, it is going to be held in a different vaughn. >> tell us where we are in the republican primary race, and also this violence is likely to have any sort of negative impact on donald trump's campaign. or is there that old maxim of there is no bad publicity, only

publicity. >> this would have derailed any other candidate and any other election, and he has merged stronger. this is no ordinary selection and donald trump is no nearly politician. marco rubio, the florida senator, saying, look, if you're in ohio, please vote for john kasich rather than donald trump. he's trying to split the vote that may well--he's trying to stop the split in the vote of the anticipate trump faction. but rubio who is still behind donald trump, knows if he doesn't win the primary on tuesday, he knows his campaign is over. and john kasich has been saying, ohio is key. ohio is purpose. he's five points behind donned

trump. what does that mean for donachie trumped? it guarantees him the nomination when you go to the convention in ohio later in the summer. >> allen fisher with us live from us from washington, d.c. thanks so much. still to come this half hour, venezuela's opposition starts its campaign to oust the president, but have their supporters he'ded calls to take to the streets? and the long trek for water, drought replaces war as the biggest threat to many afghans. >> we are on the tipping point. >> we can save species. >> it's the biggest question out there. >> it's a revolutionary approach. >> we are pushing the boundaries. >> techknow is going to blow your mind. >> our experts go inside the innovations, impacting you.

shortages of basic goods and food crisis. venezuela is deeply divided between supporters of president maduro's socialist government and those who oppose it. the opposition won elective elections giving control of the national assembly for the first time in 17 years. but since then, the court dominated the assembly's powers tease why the opposition announced this week that it would take all constitutional means to host maduro. they include valuing a ref republican democrat, calling mass protests. well, president maduro has hit back at those trying to outhim. he up assists that the brought for and he accused the

opposition the putting their political interests first. >> if they do that in the mission of an economic crisis what can we expect from thee people request nothing good. we can expect the worse. but what is more important we're here to increase undisturbed, and from there they will not get rid of me. we have to. >> we're live in caracas now. few have turned out. why do you think that is? >> there are a couple of reasons. they have to could you up outside of the food sores and try to get just a little food

that is available. that is certainly a priority. but also we spoke to other people who say that they would have easily or gladly attended if it had been hugo chavez talking on them to take the streets, but some how nicolás maduro did not cut it for them. i think what was the last larger than life leader, and the those they once counted on. >> they would use constitutional means to oust mr. maduro, but as i understand it the supreme court is will the government on most of these sorts of issues leaving protest really the only option. do you think we're likely to see the tensions on the streets ramping up in the weeks and months to come when it comes to

dealing with the administration and the government. >> it's certainly a wildcard that many people fear, that this discontent is mounting, and that spontaneous rioting and protesting could take place. the opposition has also talked about calling on a revoked referendum in a way to try to deminute their the discontent that seems to be growing every day. it seems that the supreme court would block the constitutional amendment. that's why they're going for a three-pronged approach. critics are saying that this three. pronged approach did not lead to many supporters on the street today. >> the crisis a regional issue in germany, germany's chancellor
