tomorrow morning to propose some of agreement remember the population here are very much frustrated with what th they are proposing. that's because one of the points of amnesty offered to the presidential guards. remember, this isn't just about the coup that happened last week. the presidential guards have been in power for the last 25 years. they've been i am tim dating the population and killing political opponents. here in civil society there is no question about it, they want that group disbanned. they feel that they've been robbed from these elections that were held. >> in abujo there have been emergency summits. >> they have excluded officials

of the official leading party. this is what caused the coup because the presidential guard are concerned about their future. one of the issues to be discussed was the completely disband the presidential guard. the leaders who will tramp to burkina faso tomorrow will be talking to the coup leaders about the future, and whether they will be part of any democratic process going forward. but from discussions heard today it is very likely that they should yes they should be included. yes, they believe that an inclusive democratic process is the most important thing 37 nobody should be excluded in taking part in any democratic process even if they have been behind a coup. >> well, writing extensively on cups, he explains the reactions of the presidential guard in

burkina faso. >> they have a long and contentious history with the armed forces. they were designed as a counterweight. before the president's period in office 27 years ago there were a good number of coups in burkina faso. after the rsp there weren't any successful coups, so they were successful. the rsp's relationship with the army is not a good one. the rsp is better trained, better equipped, and better paid, and they don't trust the army. that makes it difficult to understand what is going to happen next. hopefully the involvement to international mediators is going to be a positive one. there is an interest from the regional powers and also

pressurburkina faso has been very important. important. >> yemen's president has finally returned to his country. abd rabbuh mansur hadi is now back in aden from where he fled in march as houthi fighters closed in. the rebels are remain in the north of the country. in aden shipments of aid are still arriving. >> millions of yemenis have suffered over the last few months because of the ongoing fighting between the houthies and forces backed by the former president ali abdullah saleh on

one hand, and forces loyal to the president abd rabbuh mansur hadi. the aid which has been unloaded now is part of the assistance which has been provided by neighboring countries. but the international community is concerned. the problem is that the president and his government insist that they will only join political talks if the houthis surrender and hand over their weapons and pull out from the areas of control. demand which have been reject sod far by the houthis. the situation remains quite delicate, and yemen more politically divided than ever. al jazeera. aden. >> now, there are questions over the future of volkswagen's chief executive as the growing scandal grows. vw has admitted to using software that deceived regulators deceiving on toxic

emissions on millions of its diesel cars. with penalties running into billions of dollars this is the man currently under pressure, chief executive martin winterkorn. he's credited with turning the vw fortunes around? it has been reported that winterkorn will be replaced on friday. but the man himself says he's not going anywhere. >> rob reynolds has more from berlin. >> chief executive martin winterkorn apologized and said such manipulation would never happen again. >> ladies and gentlemen, many millions of people across the world trust our brands, our cars, and our technologies. i'm endlessly sorry that we betrayed the trust. i apologize profusely to our clients, the authorities and the

entire public for the wrongdoing. >> the scandal has shaken german industry. >> we're all pretty surprised by that. the a catastrophe not only for volkswagen but for all the german car makers, and it's bad for the brand made in germany because volkswagen someone one of our big brands that stand for german quality. >> even chancellor angela merkel was forced to address the stunning instance of corporate deceit. >> i hope that it will be put on the table as quickly as possible. >> volkswagen installed software that tricked emissions tests into giving the cars a passing grade even though they emitted more pollution while on the road. the company issued a statement saying 11 million vehicles are

affected. it had set aside 6.5 billion euros for recalls and servicing, and it says that volkswagen does not tolerate violations of laws and will make winning back consumer trust it's top priority. unlike other auto recalls involving design flaws or defective parts, volkswagen is accused much deliberately hatching a technologically sophisticated way to deceive. >> i think whenever you have a situation where something is calculated and malicious and there is a desire to deceive, the half life is longer for recovery. >> on wednesday a committee of volkswagen board members and major shareholders will hold an emergency meeting. a board member said that he

expects senior company heads will roll. al jazeera, berlin. >> all right, we can now speak to daniel, a mechanical engineer at virgini west virginia university. it was his reso much that helped to uncover the problem. can you explain to us, who are not engineers, and who prompted it in the first place. >> we were hired to conduct some testing of passenger car diesels in the united states.

>> we took one vehicle from the l.a. area to seattle-washington and measured emissions using commercially available missions systems. we used the systems voided by tested instruments. >> were you surprised at the initial results? yes, we've been doing this work for quite some time, over 25 years. the whole sector of emission testing we were involved in from the time of decrees with heavy duty manufacturers back in 1998. we pioneered the work used in emission testing. we've seen very good performance on emissions control. >> and when it emerged that

volkswagen was essentially cheating, what was the process? >> we had data that while we were collecting our data independently, we had colleagues from the california resourc resources board that were using the same three vehicles that we had, and testing them in a test much like would be used to do the certification testing, and we were seeing quite a disperty between the two emission levels produced by the vehicles. about a year later we made a public presentation in conjunction with icte the public forum, and we were questioned about some of the results, and we provided feedback from those. to be honest with you it had been roughly a year since we had heard anything. we assumed this had been taken care of through voluntary recall, and hadn't really kept

close track until friday when we got notification from the epa and their resources board providing information that said that the review had been brought on early on and presented the results. and the world wind of media started, and here we are now. >> here we are now. difficult for you to answer this because i know that everything that we have here is based on some very specific research. this could be something that effects other car makers as well, that they've been effectively doing the same thing? >> i can't conjecture that. i can't say that both europe and the united states are looking at what the future for regulation and enforcement looks like in compliance testing. this is one of those situations that will be used and discussed and one of the bases for redefining what the future of

the testing and compliance with the emissions will be. >> and does your research suggest, the results of your research suggest that it is the deliberate misleading of the actual emissions coming from these cars? >> i can't comment as to whether it's deliberate. i can just comment on what data shows, and we show the discrepancy between on the road performance and performance in the test field. >> thank you very much, mechanical engineer, really good to get your thoughts on this. appreciate your time. >> thank you. >> well there, is more to come for you on al jazeera. >> a rock star's welcome for pope francis on his first-ever visit to the u.s. sure, tv has evolved over the years.

catholics. those low the age of 30 hardly consider themselves catholic, and for the church they're a key demographic. they make up half of the population in the u.s. of latinos. experts say that it's a significant sign of changing times. >> i think part of it is because those who are born in the states or who women here at a very young age and are raised in the states it's not part of their up bringing in the same way. with immigration you lose that generational continue glit if hispanic are as many believe are the future of catholicism in the u.s. then the church may be in trouble. if they continue to drift away from the faithful or go elsewhere, the catholic church will steadily lose members and for now that seems inevitable. >> now the riding cost of medicine is becoming a major issue in the u.s. presidential campaign. it's been prompted by 5,000% talk in the cost of a life

most of them doubling in cost. huge price hikes for old drugs have no just any case. >> even if you pay the price your diabetes does not get 50% better when you pay 50% more. it's the same drug. it works the same way, and it has the same result for the patient if it has access to it. >> drug price something a prime campaign issue for presidential contender. >> i'm going to address starting how we're going to try to control the cost of skyrocketing prescription drugs. it's something that i hear about everywhere i go. >> but regulation would not be easy. the u.s. is the only developed nation in which drug makers are free to set their own prices even government purchasing agencies may only negotiate but not dictate what they're charged. as for daraprim, it's offering a special discount program for, quote, patients in need. but otherwise will not lower
