many sunnis in the capitol feared they would be punished for those attacks. the pilgrimage ends on thursday but the violence is not expected to end. some politicians are warning that the military achievements against the islamic state of iraq and the levant has not been accompanied by political reconciliation. >> we even we win the war and get the displaced back and we maintain the sectarian environment, then i'm sure things will blow up in the future probably in a more ugly way than it is now. >> reporter: authorities are trying to portray the violence as an isolated incident, but this is a country at war not just against isil but its communities have still not made peace with each other. at least 16 gold miners are

missing after a flood at a mine in columbia. columbia's president says everything will be done to help the victims. >> reporter: it's an agonizing wait for those trapped inside this gold mine. water flooded three of the shafts. rescuers say it could take days before all of the water is pumped out. 15 minors are missing and only a few managed to come out alive. >> translator: i survived because it wasn't my day. i was the last one to climb out. i was grabbing the poles. my friend didn't make it because when the mine fills up, it fills up with gas, and the gas drugs you. >> reporter: some family members accused a local electricity company for what happened. >> translator: my son had already sensed this. he told me this would happen. and it would be the local

electrical company's fault. they had no light to work with. he told me that last week. they are going to be so unfair to us that they are going to cut off the light. and if they cut off the light, a disaster will happen. look it was not a lie. >> reporter: most gold in columbia is extracted through illegal fines. that and a lax laws are believed to be contributing to unsafe mines. there were 87 mine accidents last year. the government says it is doing the best it can. >> translator: when i found out this morning, i gave precise instructions to the minister of mines, the national mining agency, and the risk management unit director so they with spare no effort to help those people trapped. our hearts are with the families, and we'll do everything we can to find them as quickly as possible. >> reporter: but promises of

support don't mean much to those suffering. staying in columbia where the government has recommended ending the practice of spraying toxic chemicals over coca fields. farmers have complained that the controversial herbicide has ruined their crops and health. >> reporter: since the 1990s, crop dusters have been spraying toxic chemicals on coca fields throughout columbia. the herbicide has been a centerpiece of the u.s.-funded effort to curb the country's production of cocaine. but after 20 years and billions of dollars, columbia seems ready for an about face. >> translator: we are the only country in the world that keeps using fumigation against illicit crops. there is a health risk related it to.

>> reporter: claims that the spraying causes skin rashes and other diseases which research has confirmed. >> translator: we have demonstrated a strong statistical relationship between the fumigation campaigns and those illnesses. >> reporter: the chemical has also had a limited effect on its targets. >> translator: if coca is sprayed you cut it down and four months later it regrows. legal crops are gone for good. it's counterproductive. there are other ways to negotiate alternatives. >> reporter: here farmers have tried the alternative. as part of a government-funded substitution program they switched to peppers and cocoa, but it wasn't enough. carlos is one of them. he says making the switch was difficult and expensive. but it paid until last october when his field was sprayed

again. hundreds of farmers who have stopped growing coca have seen their legal crops destroyed this year by indiscriminate use of fumigation, and feel they have been betrayed by the government. >> why did we get hit? how can you blame somebody going back to growing coca? >> reporter: if fumigation is scrapped, the government says it will focus on alternative methods, and promises to step up introduction of cocaine rings. the farmers feel ending fumigation is a first step but unless the government provides real development in the regions, many will continue to seek coca as their best option. india's prime minister is in china at the start of a three-day official visit aimed

at increasing economic ties between the world's two most populous nations. india and china have long-standing border disputes but are expected to put those aside to talk about economic deals that could be worth billions. >> reporter: most foreign leaders begin state visits to china in the capitol. but modi flew first to the capitol of the president's home province. a sign perhaps to the often strained relationship between these two neighbors may finally be easing. the president and prime minister are arguably the region's two most powerful leaders, ruling over a combined population of more than 2.5 billion, a third of humanity. they have much in common both are proud nationalists and both lead two of the world's fastest-growing economies, with

india's growth rate having now overtaken chinas. the two lead verse a lot to discuss. the president wants to promote ambitious plans to establish new trade routes linking china with europe and south asia, but one of those routes passes through kashmir, a region disputed by pakistan and india. it is though the tensions over another border the one that separates china and india that will be dominate during the visit. both countries claim large areas. it lead to a brief war more than 50 civilizations. this city is more than 2,000 years old. modi visited the pagoda which houses works translated from an -- san script. and no visit would be complete

without the visit of ter cota warriors. it was the symbolic backdrop for a leader who hopes for better relations with china. scientists say new superstrains of disease are dinnering antibiotic useless. unless drug companies invest in fining solutions an extra 10 million people may die in the next 35 years. >> reporter: a typhoid clinic in zimbabwe, these pictures were filmed during a 2012 outbreak. normally it can be treated be antibiotic, but a new superstrain is spreading around the world and is more and more infections become drug resistant, it's worrying health

experts. the world health organization has warned we're herding towards what we wall a post antibiotic era. they have also raised the prospect of infections that used to kill millions of people here in europe becoming a danger once again. now a u.k. based initiative wants drugs companies to invest $2 billion in researching more effective medicines. their prize would be one of large payment if they develop the most needed antibiotic. it could cost over $37 billion years over ten years. >> we have estimated if we don't do these kind of things it's going to cause world gdp to be 100 trillion, trillion dollars smaller than otherwise would be the case in 35 year's time.

so as a person that has thought of risk versus reward for much of my adult life $37 billion as big as it sounds is nothing. >> reporter: the idea would also remove the commercial insecttive for drugs firms to sell as many antibiotic as possible. the more the drugs are used the more the bacteria become resistant, but overprescription by doctors is not the only problem. most antibiotic consumed in the european union are for factory farm animals to produce meat faster and cheaper, the british government says the world needs to work on the demand side of the problem as well as supply. >> we need to first and foremost prevent people from getting infected in the first place, and secondly, to ensure that we make very best use of the antibiotic that we have got, that we preserve those antibiotic. >> reporter: according to the w.h.o. three-quarters of

countries have no plan to deal with growing antibiotic resistance. if the new initiative could at least convince them it is a problem, many lives could be saved. the method is nothing new, cover a roof with grass and it keeps the building below warm in the winter and cool in the summer, but in france it is now mandatory for some new buildings to a green roof top. from paris, emma hayward explains. >> reporter: this woman tends to a little piece of paradise green space is at a premium here and this communal garden is on top of a -- of a shopping center. >> translator: roofs offer a really interesting area to do things, and it's all part of the debate on how to stop global warning. >> reporter: and in some parts of paris, tarmac and tiles are being replaced by grass, plants

flowers, and soil. this isn't just a growing trend, under a new law, all roofs on new commercial buildings and industrial areas in france will have to be partially green. it isn't just to make everything look that bit nicer, it's also to improve biodiversity and air quality too. pollution can be a problem in paris. the smog sometimes forces the authorities to ban half of the cars from coming into the city. green roofs are being sold as one fairly inexpenszive solution. >> translator: green roofs are important to develop because they improve our quality of life, because in paris we don't have much green space compared to other european capitols. it's also really interesting for biodiversity. we can capture dust particles with plants and some plants capture heavy metals.

>> translator: these particles are in no way absorbed by a few green roofs. it's completely ridiculous. >> reporter: as with any new seeds that will sewn it may be some seasons before the full results of this new law are known. emma hayward al jazeera, in paris. all right. we're waiting shortly for a press conference to take place at camp david. in that is where the u.s. president is having a presidential retreat. his press secretary is due to hold a press briefing there shortly. you can see the journalists waiting for the arrival of josh earnest. this summit is being held with the gulf cooperation council. let's speak now to al jazeera's

senior political analyst. this summit, let the scene for us ahead of it. >> it has been -- it has been a few years or at least couple of years of skepticism on the part of the gulf regional council and its leadership because of what they see as america's relationship with iran something they suspect has been going on behind their backs in secret for a long time and then suddenly there was an agreement, and they were exactly [ inaudible ] of its meaning in terms of the nuclear aspect and regional and geopolitical aspect. so you could say this is a mum mum -- summit on scepticism and assurances. >> how much are they going to get out of it? who is going to achieve what though? we know obviously certainly countries like saudi arabia

they want a firm reassurance from obama. what can obama offer them? >> you know, this particular summit at camp david is going to be part of a series of discussions and -- and coordination and so on and so forth. and that's why i suspect we don't have the kind of representation that the united states was hoping for, meaning the king of saudi arabia -- >> that was -- withdrawals particularly from the king of saudi arabia it did look like a snub -- >> exactly. that's and what i mean it's part of a series. because clearly the preparation to the summit weren't enough. the preparation in terms of assure ranss to the saudis if you come you are going to get such and such. certainly the americans have turned their back on the idea of any discussion of a treaty of a strategic security treaty like the one the united states has with europe or with japan and south korea, which apparently

requires far more preparation and so on and so forth. but then there is the question of the eminent iranian american [ inaudible ]. and already we have a deal and apparently there is going to be another deal at the end of june. that means iran will have the capacity to enrich uranium on the short and long term. and it will be even more powerful in the region than it has been. and the gulf needs the kind of security assurances that if it's not a treaty then what? i think they want a serious defense system to be manned by the united states or helped being manned by the united states. they want the kind of soft indicated weapons that the israelis have gotten. but more than anything else my feeling is that the gulf leaders

want the doctrine that was instituted under president carter in the '70s that said look, the united states commits to the protection and defense of the gulf countries in case of a threat. that was never actually officialized. it was a friendly commitment if you will. they would like to have this official. they would like to have it strategic on the long term in order to protect them from any potential threat. >> interesting as well. obama obviously is acutely aware of the sensitivities and anxieties of the gcc. a couple of days ago i think it was, he gave a rare interview to a foreign newspaper where he was quite harsh on iran. a deliberate policy in advance of the summit? >> back to his interview to the "new york times" several weeks ago, and i think that's one of the -- that's one of the comments that he made that apparently upset the saudis the

most is when he said look you are going to face no threat from iran. this is all delusional if you will. the threat is going to come from the domestic discontent which kind of bothered them a lot that now he's interfering in the interior affairs of these countries without even committing to their security from the countries like iran that is witnessing [ inaudible ] with the united states. that upset him a lot and especially because -- particularly the saudis -- but also the other countries are sensitive to the idea -- or at least they claim that a potential iranian interference in their own affairs locally, domestically in the gulf countries could lead to instability and potential violence, and hence that should not be seen as something resulting from their rule but rather from iranian interference as they claim as has been seen

in iraq syria, lebanon, and as they claim it has been seen in yemen. they don't want iran also to medal in their own countries as far as they are concerned. >> you talked about yemen, and clearly iran is going to be top of the agenda as far as the saudis are concerned, but yemen too is a hugely important issue at the moment. presumably the saudis looking for even more backing from the u.s.? >> there are now about five or six disagreements between the united states and saudi arabia on the question of yemen. number one, the -- saudi arabia has accepted a ceasefire, but the united states would like to see a quick move from the military to the diplomatic arena. saudi arabia is taking its time and wants to make sure all of its military goals are fulfilled. two, the americans would like to see an international sponsorship of these talks, because if it's just going to be saudi --

>> well the houthis have said they will not go to riyadh. >> exactly. >> so the united states is pushing to say, we need to go somewhere else because the houthis aren't coming. but as far as saudi arabia is concerned, they are not legitimate anyway because they are the one who have been medalingmedal medaling yemen. third i think the united states would like to see a role for iran. secretary kerry said i have spoken to a certain foreign minister who assured me the houthis would be happy to come. clearly he meant iran. i think the iranians can help with the houthis, and hence they need to be brought on board. and the united states would like to see a move towards national reconciliation in yemen. and they don't like to see that

part of the world destabilize, especially since there has been this idea that the iranians are going with their own ships -- >> and not allowing inspections. >> exactly. so that could lead to the incidents. >> do stay with me. let's head back to the u.s. and speak to alan fisher who is waiting for this press conference to take place. particularly from the point of view of those gulf cooperation council countries, what is the u.s. looking to get out of this particular summit? >> i think when it comes to the end of the summit we could almost see gcc bingo. there will be certain things that will be said that we would almost write right now. that they are committed to working together. they were reassured about america's support and commitment to the gulf cooperation council.

but i think what happens at the end of this summit will be very telling. if barack obama is there on his own, not taking questions standing with no one from the gcc by his side we can assume things did not go well. and there will be pressure put on the gcc, to put someone in the room with barack obama. but as he has been explaining this discontent that america is cozying up to iran so they want to hear exactly what this deal will mean. the countries have been briefed extensively by john kerry and other diplomats, by ambassadors in the capitol to let them know what is happening in these talks. what the gcc will want to know is what america will do next. barack obama quoted in an arabic newspaper on thursday saying

look we know iran gets involved with the houthis in yemen. it is involved with hezbollah. we know it continues to support syria and bashar al-assad but think about how much more bold iran would be if it had a nuclear weapon. barack obama is getting the gcc on the table and saying look we know iran is a problem, but this deal is good for us and the g cc. we heard from josh earnest on al jazeera when he spoke to patty culhane. but to give them more arms sales, or perhaps describe them as non-nato strategic allies and that opens up all sorts of geopolitical and particularly military support for the gcc. their hands are tied to a degree because israel has to have an advantage. but the u.s. will be hoping that the gcc will leave here feeling

the love from the white house, slightly reassured, but given as he says the difficult relationship between the saudis and the americans over the last two years, there is no guarantee that that is going to happen. and many will suggest that the white house perhaps miscalculated by deciding to hold a summit and it not to be an overwhelming success because in the u.s. wider world. >> how much of a snub was it, the fact that he gets only two of the gulf cooperation council leaders showing up? >> ill health also plays a part here. but i think marwan summed it up succinctly when the said the summit was announced. announced that the saudi king would be there and a couple of

days later, the saudi king said no, i'm not going to be there. they can say it is because of the ongoing situation in yemen, but i think it's perhaps true that the king didn't get what he wanted going into this meeting. he wasn't going to walk away with what he felt would be a good deal. the saudis didn't send along someone who was just walking past the office at the time. they did send the defense minister, and the foreign minister. two people who the americans deal with on a day-to-day basis particularly when it comes to yemen and also with isis. so they are high-profile people here, and they will discuss things and be able to go back and report to the king what has been discussed here but it is embarrassing for the white house that they didn't get their first choice as it were all six leaders sitting around the table with barack obama and he is

slightly diminished because of that. but the amirs of kuwait and qatar are here and both are important. >> thanks for the moment allan. now back to london. the president of the united states has a little balancing work to do in his job, but what to the gcc actually view him? and how do they view him as being a friend to the gulf? >> i think that's a very important question because we need to place this summit within a context of sort. since the beginning, the idea that barack obama wants to contract, you know, the superpower and itself involvement in the middle east. the fact that he was insistent in withdrawing from iraq not attacking syria, was his dent to get involved in libya. they are suspicious of his intentions not to get involved

when they need him most. they are skeptical of obama, and when you read some of the reports from the gulf what they write about is after obama. that's what most of them are already thinking about. and if they are not coming today, because they will probably show up for the next summit with the next president. it is also his legacy -- is to have a deal with iran something they suspect. >> thanks for your analysis appreciate it. that's it for this particular hour of news join me again in a couple of minutes for much more on that summit at camp david.
