open your eyes to a world in motion. this is the al jazeera news hour. i'm david foster live from london. this is what we will look at in detail for the next 60 minutes. desperation of these migrants sent back to libya as they try to reach europe. also coming out, the u.n. urges the saudi-led coalition to

stop bombing airports in yemen so help can get in. police in texas investigate the backgrounds of two men shot dead after opening fire outside a far right conference. ifrmths . i'm andrew simmons reporting from a mountainous region from nepal, and i'll explain why some of the aid isn't getting through to victims of this earthquake. >> i'm robin adams with all the sports. i'll tell you who it is later in the program. also ahead, andy murray gets his bench open trepidations off to a winning start. some make and some don't. those that don't, not all of them perish as so many have. they're left stranded. the latest migrants rescued from people smuggling boats in the

mediterranean have arrived in italy. in the last 48 hours alone, nearly 6,000 people have been taken to the italian port. in a minute we hear from stephanie dedekker of those arrivals. what of those turned back? she met some whose dreams were ended after he set off from the north african coast. >> reporter: by now they've been at sea for over 12 hours. it was a smooth sail. they thought they had made it if it weren't for the libyan coast guards. we ought up with the boat off the shores of western libya. the coast guards have carried out an overnight rescue operation, five rubber dinghies each with about 100 people on board. they come from nigeria, ghana, mali senegal and beyond. men and women, young and old. you want to go to europe?

many of the migrants here are not happy they're returning to libya. to reach this point they have traveled for weeks, sometimes months. they have to work to earn enough money to pay for the journey, and to be picked up on a day where there's good weather conditions is a huge disappointment. it's back on land in libya that it becomes clear how much of a disappointment it is. how hungry they are. and how vulnerable they feel. >> please help me. help me please. i'm on my way going there. i'm almost there. please help me. let me be dead. please. >> reporter: their stories with ones of people trying to desperately escape the turmoil they were born into. [ screaming ] >> reporter: she's from ghana and three months pregnant. she was hoping to give birth in italy. >> i'm very stressed out and frustrated.

i don't know where to go and i don't know what to do. right now i have nothing. i have nothing. i have nothing. >> reporter: she's from nigeria. her father was killed by boko haram. she promised to send money back to her mother when she set off. >> i don't want them to deport me. i don't want them to deport me. >> reporter: so many people die in the sea. >> we don't care. we don't care! >> reporter: some of these migrants first arrived in libya to find a job, but the lawlessness made they decide to go further north. he paid extra for a life jacket. >> for you from here we're going this place. >> reporter: are you worried about it? you look very nervous? >> yes.

some people die of hunger here. >> reporter: it won't be easy. for now they're in a detention center somewhere in libya hoping to be released soon and try their luck across the mediterranean sea once again. they approached the port in silence. silhouettes in the dark sky. the boat has just docked and it's quite a powerful moment as the migrants stand silently as the boat has just come to shore. many of them, of course, with incredibly difficult stories to tell. they've risked a lot to get here. many won't know where they're going from here but certainly this is one of the first times that they would have felt safe in a very long time. almost 900 people were on board after being rescued on saturday they finally docked in sicily in the early hours of monday morning. >> it never stops.

we talk about the emergency, because there is not really a sudden emergency, but we know that it's a chronic condition repeating again and again. >> reporter: it took hours for the migrants to disembark. the emergency cases first, but as there's a one by one medical screening for so many meant it was slow going. their exhausted-looking faces a hint of what they've been through. we were not allowed to talk to any of them. italy's ministry of interior decides where they will go next but not all want to stay and will try their journey to other countries. their future remains uncertain, but for now they arrived to a new day after a invoicingage in which they risked their lives. it's a journey thousands more will attempt and not all will make it here alive. hour-by-hour the situation changes, so this is the latest we've got from stephanie dekker in italy.

>> the italian coast guard says there's a few ongoing rescue operations in the mediterranean. thousands have been rescued the last few days just an indication how many people attempt to take this journey. this good weather is set to last. it takes around 24 hours once the migrants are rescued at sea to come to shore. they have the difficult task to allocate where they go once they come to show. they get rigorous medical checks and get identified and they move on. it's concerning. we've seen people come to shore in different conditions. they've been through harrowing times. medically some of them were injured and taken straightaway to hospital. we managed to speak to one man on that boat. he said that there were six palestinians from a refuse new camp and the refuse knee camp in syria besieged by the syrian government for years has been infighting amongst groups.

isil is also inside. incredibly difficult to see how people make a dangerous, long and expensive journey for them and finally arriving here. when they arrive in europe yes, they're happy. it's still a very uncertain future as to how their lives were unfold. austria's is asked for a eu quote yent to accommodate the refugees. so far this year almost 1800 people have died crossing the mediterranean, at least those are the ones we know about. an estimated 40,000 have made the dangerous journey since january, and officials expect the total number of arrivals for 2015 to top 200,000 in italy alone. let's talk to the southern europe spokeswoman for the unhcr. she's joining us via skype from rome. i was interested to hear you say

that we need measures that might offer a safer way for refugees to get to europe. how would that work in your opinion? >> the fact that at least 50% of those coming to europe crossing the mediterranean arriving to greece 50% at least of them are refugees. people coming from syria, people coming from somalia, they would in my case have received a refugee status once in europe. so unchr is proposed 12 actions very specific and concrete. some of them focus on the fact that these refugees should be provided with some attractive legal ways to arrival in europe. so europe should open for some quotas and provide these people with different kinds of

possibilities from family reunification. we have families that are broken because of the war. the father is in europe the mother with the daughters with children are in libya waiting or in turkey. so family reunification is already into the european regulation and should be facilitated. then we have the possibility to increase the resettlement quarter. we know that some counties in europe have done a lot, like germany, for example. some others might do more. some countries will start to increase their settlement quotas, like italy for example, for the first time. first of all, we want to bring these people out, to pull these people out of the hands of the smugglers. we should give them something attractive. >> can i ask you this? this is something that i think has been largely ignored. we talk about the human traffic

from the north african up to malta and sicily. you alluded to it and i want to to ask you about it. the traffic from syria to turkey and then they go to greece. how much of a problem is it there in the northern part of the mediterranean? >> you know trafficking networks are much ahead of the policies in this moment and this is why it's so important to bring refuses out of this. the worst thing is not only we have trafficking networks operating with different more or less in libya, in asia in turkey, but there are trafficking networks operating in europe on the very same european land. >> so how many people are trying to make that journey as well? how much of a problem is it for them and for, let's say, the greek authorities?

>> well you know, the numbers the people that are trying to make the journey is likely increasing from turkey to greece. mainly it is syrian refugees all of them. some iraqis also. and then the people that are trying to cross the mediterranean in the central part from libya to italy, this is a trend that is confirmed in comparison to last year. so what we are looking at is that the numbers of this year people crossing are basically aly bit higher than the last year. what is more worrying for us is the fact that much more people have died this year. >> let me turn to something, if i may that was agreed in this euro-wide summit. the urgent action and the vary countries said they would send military vessels to help with the patrols off the coast of

libya. others would offer different kinds of assistance. we're talking two weeks ago, and i know it's difficult to put together. in two weeks an awful lot of people died. do you think there's an urgency for these things that are needed or not? >> well we preachappreciated the fact that in strausbourg for the first time it was very clear that the awareness about the importance -- i mean relative to this cry? front of everybody. for the first time the european union took the decision to share some -- >> have they -- >> sorry? >> have they done enough in the time they've had since that meeting? >> well before that meeting we were saying all the time that the u.n. had done too little and too late. we can see that in terms of the rescue operation, at least the attitude is more cooperative.

it's still early, it's still early to evaluate after a few days what are the effects, the concrete impact of the decisions. of course we will continue with our proposed actions, because proposed action number one is not only thes are s ares are s ares are re could you at sea. otherwise, if we close the door they will try to enter from another door because they do not have any other places to go back. they will try anyway to come. >> thank you very much indeed. >> you're welcome. >> as you say, you'll keep up the pressure and we will keep monitoring it. thank you very much. now to nepal. rescuers there find more and more bodies as they reach at least areas cut off by the earthquake. in one village 100 people were buried by an avalanche. we reached a north village that

was badly hid. the crucial road was blocked by landslides and that meant people couldn't get through to the people that badly need it there. andrew simmons has this report. >> reporter: ruined villages on every mountainside. no one is here to help so they're getting on with it by themselves. this isn't rebuilding. it's about clearing up the best they can attempting to recycle the timber and rubble to built temporary shelter. more than a week after the quake, there are no tents. not even any basic plastic sheeting. further down the mountainside a proud family man works away. everyone is helping. he struggles to hold bacterias. -- back tears. >> translator: our lives have gone. how can we rebuild? what can i say?

where will we get help? who will help? >> reporter: this is what's been stopping anyone reaching villages beyond his home. landslides caused by the quake and aftershocks. the road ahead has been blocked for more than a week. our vehicle is one of the first to get through. the road ahead is treacherous. no aid convoys here. you can see how much aid is needed though with one glance at the village of tadi. out of 90 homes only four are left standing. army patrols pass through. their task is to search for missing people including foreigners. small amounts of food have been left for them, but helicopters pass by on other missions. this is an all too familiar scene. so many villages like this one decimated. the people show a remarkable resilience but is it enough to face what lies ahead?

unless there's rapid assistance raj who has a wife and baby doesn't think he'll be able to cope. >> translator: we have nothing. however much we dig, there are only stones. we have no food. how will we survive? that's what it comes down to survival. not just hardship and the rain and cold of the monsoon season could be only a month away. andrew simmons, al jazeera. stay with us if you can on the news hour. we have this coming up. the violence in the capital as police try to shut down the latest anti-government protests. the parliament considering extending digital spies in the wake of recent attacks there. and what he believes about this. we have that and more sports on

the way. saudi arabia is considering a truce in yemen to allow in humanitarian aid. the saudi-led coalition finding houthi rebels carried out air strikes targeting the runways at sanaa international airport and other airfields across the country. the u.n. says it makes it impossible to get aid in. >> translator: partners report difficulty providing medical services as a result of the current security situation and continued air strikes tarreds sanaa and sadda. food partners have reported they have to suspend assistance in hurati district also because of a lack of fuel. casualtyies of the numbers of displaced continue to rise. the local resources say there were widespread violence and

the humanitarian for yemen asks for the coalition not to target sanaa airport so humanitarians can reach all affected by the armed conflict in yemen. >> another country is joining that sawed dpi-led coalition. how many troops and what are they going to do there? >> reporter: well the announcement was made by the form rin minister to a handful of mps at the national assembly on monday. we're talking about 2100 troops. senegal is an experienced keeper under u.n. mandate. nowhere does it have 2100 troops. we're talking about armored vehicles pair troopers and commandos. they will be based at or around the saudi -- the 1,800 kilometer saudi border with yemen and

patrolling that border with the saudis? >> what's the deal here nicholas? this is a gulf fight. it voovl involves members of the gulf cooperation council and saudi arabia and yemen. senegal is a western african country. what's the tie-in here? >> well this announcement just comes weeks after the president went to meet the saudi king. he came back from that visit saying he will supports any saudi-led coalition. but the official version here gifrn by the for minnesota industry is that as a muslim majority country, senegal has an obligation to protect the muslim holy sites in saudis. there are certainly people here that say there's another game at play here. the senegalese are trying to

raise funds, $21 billion to turn senegal into middle income economy. it's looking for the saudis to do that. >> thank you. nicholas hart there in senegal. >> qatar signed a deal for raphael fighter gentlemens from france. it was during the capital of qatar, doha earlier. the french president meeting the amir amir. he's now in saudi arabia where he discussed iran's nuclear program. the syrian military's head of logistics survived. they al qaeda-linked front was behind the fact as vicktoria gave me reports.

>> the israeli police use nonlethal winnipegs and only water cannons to disperse the crowd. we take into account the range and sun grenades are effective and only make noise and scare it off. it causes no damage whatsoever. >> reporter: the center of tel aviv is cleaned up but little will wash away the stain and shock between the violence. coming up you opt news hour why a shortage of affordable housing is important in the election cam taken. we're at the boat at that book fair where respects are paid to gabrielle, and where someone watched off with one of his most valuable books. robin is standing by with the details. details.

austria's chancellor called for an eu-wide quota to accommodate people reaching europe's southern shores. 8600 have been rescued in three days. rescuers in knee pap find more and more bodies as they reach areas cut off by last month's earthquake. in one village people were buried by an avalanche. saudi arabia says it's considering a truce to allow humanitarian aid to reach the country. now to burundi. the red cross said three protesters were killed and 45 hurt in violent confrontations with the police. the police for their part say a grenade was thrown at them injuring a number of officers. the activists are angry about the president's decision to seek a third term in office.

defined a battle. the leaders of the op pox calling for protests across the country to be held at about the timing of elections. they want local polls to be held before the presidential election scheduled for october. the united states is going to give $45 million to help kenya deal with increasingly difficult refugee crisis. u.s. secretary of state john kerry promised the men to the u.n. refugee agency operations to help about 600,000 refugees. more than half of them are somalis in a karnt that kenyan officials have threatened to close. >> this funding is part of our effort to maintain our long-standing commitment and kenya's long-standing commitment to be able to provide haven to refugees. what this money will mean is better schools. it meepans access to health

clinics and will benefit refugees and also particular the kenyan communities who graciously act as hosts. u.s. authorities say they are investigating any possible links between gunmen shot dead by police in texas and groups such as isil. police killed two people on sunday after they opened fire outside a conference exhibiting cartoons of the prophet mohammed. the police officer spoke with the media near the center where the shooting took place. >> he did what he was trained to do.: he did a very good. od. >> we think their strategy was to get to the event center and that they were not able to get bas past that outer perimeter.

>> let's bring in jay gray from garland. that's the dallas suburb that is in texas, and there's been an awful lot said since the shootings and we don't know what the motives behind the deaths actually were. >> reporter: no a lot of speculation, david. you can see the fbi evidence team still working at the scene. here is the car that the suspects were in when they drove up to the events center here. a lot of evidence markers on the ground here. i've counted numbers up into the 70s at this point. a lot to comb through here and they've done that since an hour or so after the shooting and they will continue to do that throughout the evening in what police describe as a long and tense and very meetic lues investigation in the beginning stages here. both of the men involved here had some interaction with federal agents.

one lied to federal agents and was convicted and had planned to travel to africa to join a tourist group there. the other on the terror watch list, so that's a key to this investigation and points to a tie with what was going on at the draw of mohammed event. it was an event and showing of art using the prophet's image. there was also a contest here for cartoonists, a $10,000 prize for first place for the cartoon they depicted as the best using that image, david. >> well i mean the governor of texas is saying this is a terrible crime. at the same time he's saying free speech. we have it in this country. you have to live with it. >> it was a freedom of speech forum, and a lot of people say speech is free regardless of whether you like the message or notted. it's a bit ionic in january

there was another event here hosted by a muslim committee here here. it was an effort to explain what their religion was all about. so at that event they were close to 1,000 protesters anti-muslim protesters here. they knew going in it was an issue and the group that sponsored the event this week and paid an extra $10,000 to have extra and added security here including members of the s.w.a.t. team from the garland police department. that paid off last near. could have been worse here. especially when you take into account they drove up to the event center at the time this event was supposed to be ending. there could have been 100 or 200 people in the parking lot at that time. it ran long so no one was here. i think you hit it right on the head there, david. could have been much worse and police acting quickly here and

the investigation which is anything but quick. >> thank you. jay gray in texas. about this time in three days we're going to get a hint of what's to come for the next five years. the state of the economy and concerns about immigrants right now are the key issues. voters appear to also be worried about the cost of housing, especially for young londoners, as laurence lee reports. zo on the banks a new quarter of london rising into the sky. that's an acute shortage of funding. a one-bedroom flat costs over $1 million and most of is already sold. the new american embassy will be here. the developers went out of their way to mark this entire area not

to londoners but wealthy foreign investors. the vision is tempting. he could install his girlfriend in a flat. he might rent it or leave it empty, but the whole district is irrelevant to 99% of people that live in london. >> the center of london tends to attract money, some russian money and middle eastern investors are looking for prime product in the middle of london. far eastern is middle to upper class investors who invest for their pensions and children. >> down the road developers have their eye on another lucrative plot. one is slated for demolition. isin has lived here for 20 years and spends her time helping victims with domestic violence. as the wrecking ball hits here she'll be out of london because she can't afford the prices. >> they are forcing us to go outside of london to some other small towns.

at the moment what they're offering us we cannot afford to live in london anymore. >> reporter: nearby housing for poorer people has already disappeared. developers took the road shows to investors in places like singapore, mumbai and beijing that charge thousands a month in rent. all over london the cranes are moving in. they protest, but the noise of capital drowns the voices out. >> this will create a dead heart of london and we're against that. we want a living london. this is our last stand against social cleansing of inner london. >> reporter: successive governments have let this happen. after winning power in 1997 tony blair's first act as labor prime minister was to visit this very estate. he said there would be no forgotten people in the britain he wanted to build, but his government first came up with

the idea of knocking down these people's flats. it brings us back to the elections and the endless debate about the skefshing and unskefshing poor and whether there shouldn't be a cap. yet, nowhere in this national conversation is there anything about the role of rich foreigners whose actions have made it incredibly difficult for many, many people to live in london at all. housing inflation is such that a leading charity found just 43 homes in all of london were now affordable for first-time buyers. thousands of young people had to move out of the capital entirely failed by politicians and a market dominated by rich investors. laurence lee, al jazeera in london. the french parliament is something to vote on a law that prosing wider intelligence gathering powers. it's a bill that would force internet companies to monitor users and it's gained widespread political support after january's attacks in paris on

the offices of the magazine "charlie hebdo." some people are worried that the legislation could be misused. >> reporter: the paris attacks on january 7th sent shockwaves across france and signaled a major change in the ballouchy mood. soon after the attacks, the political left and right came out into the streets in their millions united by the feeling that something significant needed to be done to protect france and prevent more violence. this is how the french government responded. with a bill proposed by prime minister manuel broadening state powers of surveillance. >> the public opinion is asking for more security and applauding police, which in france is quite new. this is all very important. >> it would force internet companies to monitor suspicious behavior employing black boxes

to filter communications. it would allow spy up agencies to tap phones ander mails without the need for permission from a judge. microphones and key loggers monitoring computer use can be extensively employed. they have marks $450 million toe recruit extra security and intelligence offices. all the bid has widespread support in the french parliament elsewhere concerns are growing. some of these sdmon straighters are from internet companies. journalist and activists feel that the french government puts state security above privacy and civil liberties. web companies are worried the laws could frighten the way some customers. some are saying they will relocate outside of france if the bill becomes law. >> whether i've liking for the jihad wikipedia page is it

suspicious activity? this is what mass surveillance is all about. it is wrong because it creates self-censorship. >> the french government insists all targeting will be monitored. they're keeping an eye of 1200 individuals. while the spirit seen during january demonstrations remains strong so too, is support for greater government powers. al jazeera, paris. . his best known book has been stolen from a fair in the capital of bogota. the signed first edition of "100 years of solitude" worth a record $60,000 and was on loan to the fame. despite his fame in his home country it remains rather low.

>> reporter: the guest country at this year's international book fair in bogota is an imaginary one. the enchanted place invented for gab gabrielle who died a yerlg. >> it's a nation that resembles clutch ya and latin america. it resembles our widest dreams. >> the exhibition immerses visitors in the literary landscape made famous by "100 years of solitude" and connects them to the book. it's like looking deep into a magical mirror that looks at passions conflicts and contradictions. here in colombia outside of major cities few have ridden. despite incentives to increase readership, still over half

doesn't read books. most cities and towns in clutch ya don't have a book starstorebookstore. they're expensive and considered a luxury item. the government response so to build pub labor braers in poor radio johns and provide free access to books, computers and technology. 104 new libraries have been built in the last four years, like this one. it's deep into a territory hit by the country's internal conflict. >> translator: this anxiety and desire to know the world can be achieved from books. >> with the help of volunteers and still a head start in the mobile version of the library where books are brought into isolated rural areas under rebel control. >> translator: i remember we once walked five hours to reach a village.

when we got there, there were 60 people all waiting for books. >> for her work she's been rewarded with the national prize and over $20,000 to expand the reading programs. mostly aimed at the next generation of readers. it's an uphill battle in a country still working to improve its education system. but in this small town they're fighting it one page at a time. we will look in a moment on this news hour the robots help stroke victims on the slow road to recovery. we will tell you why it was a monday in may to remember for the seaside town in the u.k. we'll have that and the rest of the sports. orts.

>> to help unearth secrets of the past we foun a scientists that looks down from space and into the future. dr. sarah parkik is a pioneering archaeologist using satellite images, she was the first to map egypt's lost city of tanis, creating an incredibly accurate current take layout of a city that hadn't been seen in 3,000 years. she discovered 300 tombs in 1,000 ancient settlements. >> you may see you guys digging around in the dirt and you wonder why. >> if you look back you learn from people in the past about who you are today.

the reality is we haven't changed. we're the same people that built the pyramids and we're the same people that built stonehenge. when we look at the archaeological record in one story in egypt there's an inscription in the western desert and a guy is writing on the face of a cliff, i can't believe how much i had to drink. my boss is so angry. i can't make it to work together. this is 3,000, 4,000 years ago. nothing has changed. >> nothing has changed. >> a few things have changed over the past 4,000 years. the world has grown en incredibly complex. they have embraced it as a way to advance the field of archaeologicalarc archaeology archaeology. >> satellites allow us to be much more focused in terms of excavation in the survey. archaeology is facing a number

of challenges regarding funding as well as access to sites on the ground. we absolutely need new scientific approaches to allow us to know exactly where to go and what to dig. otherwise we waste time and money. >> to find out how this works, we turn to the experts at digital globe who own and operate the largest and most advanced commercial satellite constellation in the world. what is remote sensing? >> remote sensing, believe it or not we all do. it's sensing without touching something. so our eyesight our ears all need nor sensing. what you talk about here is a camera and this is from space taking pictures of objects without touching them. >> based in boulder, colorado, ball arrowerospace is an experienced leader in building and launching satellites. they're constructing the world view 3 for digital globe. the production floor resembles a giant operating room for spacecraft. it is an incredibly secure

location to which we were given rare access. the world view 3 satellite scheduled to launch summer 2014 represents the latest and greatest advancements in commercial satellite imaging. flying 3 # 0 miles above the earth, it's enhanced image sensors see through dust fog, and smoke and haze and can see below the earth's surface to discover ancient buried cities currently invisible to the naked eye. >> we already have five satellites that take pictures of the entire globe, so what we have on the satellite are what we call red, green, blue. this is what we see with the naked eye. we have a band called the ray. we have added more bands in what we call short wave. an area of it is rich with information about foresty, agriculture, geology, so there's a lot more to do with these new

bands we cannot do with our constellations. >> it's a new wavelength of light you can detect? >> that's correct. we call it invisible light. with the inindividual i believe light this is the shot of infrared that uses powerful information. >> world view 3 will allow archaeologists and scientists to see into the middle infrared and that's different because it will allow us to see what currently are completely invisible signatures from geo geological samples on the ground our buried in the greed. >> our philosophy is there's so many brilliant people out there, let's leverage their capabilities and knowledge. we took some other things we're doing and created something we never thought about it. we're focusing on current planet and how it's changing and how we're talking about what has happened 4,000 years ago, 10,000 years ago to the present.

>> a not so pleasant surprise is alarming rise of looting at these ancient sites detected now from space. >> following the arab spring many of the guards at the sites in egypt and syria went away and so a number of individuals have gone after archaeological sites. what we have done with the satellite data is mapped thousands of these looting pits. this is a multi-billion dollar industry and they're trading them in many cases like in syria, afghanistan and iraq. this is helping to fund and support international insurgency efforts. there are a lot of similarities between blood diamonds and looting archaeological sites. >> he's working with the doctor on remote sensing projects in egypt. >> what you have here are two satellite images.

this one was taken in 2010 before the start of the revenue on the right, and then on the left it's taken the end of 2012 beginning of 2013. you can see all these hundreds of black holes are looting pits. >> we found this kind of loots has increased. it's very huge. i feel so bad because some people didn't know about what they're doing. they just go and do that and that's not good because once you destroy it you will not get it again. you will destroy your history. >> the ultimate goal is to set up training programs so that we can train the really bright enthusiastic young egyptian men and women to use this new technology because ultimately it's the egyptian people

responsible for protecting their heritage. >> how cool was that? people have been archaeologists for centuries, and we're living in the most exciting time thanks to technology. >> it was so exciting for me coming from a military intelligence background is i think of us using this technology to discover things like underground bunkers and weapons of mass destruction. to see it unearthing the secrets of the past something fun and exciting was really night. >> these are the best commercial satellites and can be rented out for those purposes. some governments use it for that and less nepharious prurps. >> thank you for the stories well. another fascinating week of tech know. check us out next time. time.

saudi arabia considers suspending air tribing strikes to allow humanitarian aid. i'm david foster. also coming up the desperation of the migrants intercepted and sent back to libya as they try to reach europe. we're in a remote corner of quake-hit nepal to find out how people are surviving without any help from outside. remembering colombia's literary legend. we're at the bogota book
