missing in the western state here and the people are not just calling for justice in the on going investigation, they are calling for the suspension of elections in the state here which are set to be held only june 7. they say if anything those elections will just produce a continued corrupt political class and a political class parked with people with ties to organized crime and say this is a state run by drug trafficking organizations. it's very likely the federal election will support this proposal because that would be an admission that democracy doesn't truly exist in mexico and that is something that the president is unlikely to want his government to be admitting and we have been speaking to people and here is what they had to say about why there shouldn't be elections. >> translator: i don't think elections right now would do any good but we are trapped because we don't believe in incising violence and don't want to over throw institutions in a cue.

some air strikes which are obviously attacking places of strategic importance, the presidential palace other areas where they believe that houthi military powers are concentrated. but how successful it will be that is hard to say right now. historically this is unlikely to be very successful. air strikes are only very effective if they are immediately followed up with ground exploitation through ground forces. >> i was going to ask you about that sorry, what are the chances of ground forces and who has the courage to put boots on the ground? >> well the saudis have been very unclear about their intentions here. they said something along the lines they are studying ground of options and already mobilized some ground troops towards the border so there is a sort of

half-hearted hint at ground forces. egypt and other countries have suggested they might support an invasion with ground forces but it's a very -- it's a very difficult thing to do, setting in ground forces into a situation like this. we have seen what happens when even western forces go into a different country such as iraq and afghanistan, getting in is not difficult. getting out is a major headache and it's very likely that if the saudis lead a coalition to invade yemen it could be the quagmire that the u.s. faced in iraq and afghanistan. >> where do you think this leaves i.s.i.l. and al-qaeda if they go in with further air strikes and ground forces? >> that is the other complicating issue here because yemen is a very complex structure and if you weaken the

houthi and yemen army that are aligned with the houthis, then you end up strengthening al-qaeda and i.s. both of whom are as we know very dangerous organizations. and their ambitions go beyond purely yemen of course. their ambitions are very much aligned to saudi arabia and of course they have some sympathizers within the middle east throughout but particularly in saudi arabia. so what we could be opening up is a far more dangerous situation than even in syria right now in the longer term. >> let's leave it on that point. good to have you with us thank you. russian-launch crews on two continents putting the final touches on rockets scheduled to blast off less than two hours apart. one is sending two satellites into orbit from the jungle and

the other has a three-man crew to the international space station, the future of the international space station is in doubt and tom ackerman explains. >> reporter: one of the world's greatest engineering achievements thanks to 100 billion more than 140 rocket and shuttle launches and 180 space walks. bigger than an american football field the international space station equals the weight of 300 cars and/or bits the earth in seconds and u.s. and russia and 13 other nations where they performed hundreds of plant and physics experiments but for nasa it's a stepping stone for earth to each another planet. >> on a journey to mars make no mistake this journey will help guide and define our generation. >> reporter: cost over runs and technical glitches forced a scale back of the station's original grand design. >> the element that survived

throughout it all was to facilitate human exploration further in space. >> reporter: i.s.s. was supposed to be shut down by 2020 but u.s. president barack obama has committed through its operation through 2024 and audit questioned that talking about capacity for transporting large replacement parts at short notice and solar panels wearing out sooner than expected and a matter of cost private money to maintain the research projects has been running short and america international partners slow to extent participation and include russia and say vehicles are the only man transport to the station since nasa ended the shuttle problem and car goes and due to taxi astronauts by 2017 russian officials say their country is getting the short end of the station's commercial

stick. >> translator: we want to create problems for the russian rocket space industry. >> translator: the americans have been attempting to cause as much damage as possible to develop in the russian space. >> reporter: later this year a new russian cosmo drone will open and it may be preparation for building their own high altitude orbit station in the next few years. >> nobody is making much of a profit in space these days and building separate space station might be an attractive idea but that would be a huge investment of funds as well. >> reporter: so for this generation of enthusiasts the center piece of space exploration will remain that huge lego set, some 300 kilometers above the earth, tom ackerman al jazeera, washington.
