last remaining rebel group in colombia is being blamed by the government for days bombing of that police academy at the government has been speaking out about this alexander i'm p.f.c. brings us the latest now colombia's defense minister and the attorney general say they have enough proof and intelligence that demonstrates according to them that attacker was indeed an explosives expert for the land rebel group that you had lost his right hand in a previous explosion and that he had been responsible for explosives training in rebel camp in different regions along the border with venezuela where the operates and that also the the man that was arrested in the early hours of friday was part of an urban cell here in the capital bogota the attorney general says that allegedly he was caught on the phone speaking about is role in these

attack if paul this is true or the government believes that to be true it could also have of course consequences on the ongoing peace negotiations with this rebel group the last one standing in colombia we're expecting the president. to make a decision on these peace talks later on friday at the end of a security meeting that's been ongoing since friday morning. still ahead for you on the program we're at the eastern end of the five hundred kilometer irish border where locals warry back to offer up barriers to their businesses and fears about press freedom in guyana following the murder of an investigative journalist who helped expose widespread corruption.

get a welcome back to the national weather forecast all things are looking much better down here towards the southeastern part of europe all the rain the windy conditions in the snow has ended so are much clearer as you can see on the satellite image across that area but we are seeing the weather is out here towards the west and they have been princely is seeing a system coming out of the atlantic it is going to bring some winds as well as some very heavy rain over the next few days for parts of spain as well as portugal up here towards the northwest though london it is going to be a cloudy day for you here on saturday with a temperature of about five degrees now as we go towards the end of the week it will be seen that system out of the iberian peninsula make its way towards the central part of the mediterranean and it is going to bring some rain showers as well to the southern part of france over the next few days let's go down here towards another part of africa that same system is also going to be a factor here so we're going to see an increase of rate particularly over here towards morocco for algeria as well along the coastal areas not looking too bad here on saturday but as we go towards sunday we are going to be seeing an increase

for a little on the areas along the coastal areas there with the windy conditions also beginning to develop so for robot it is going to be a rainy day for you at seventeen algiers rain in your forecast at fifty but tunis partly cloudy conditions here with a temperature of sixteen. we're talking about ivory poachers who have decimated populations of elephants in africa they almost always shipped the ivory out of a different country from where it was poached because that's where you start your search to look in the wrong place this radiocarbon dating method tell us their trade ivory is legal or not then we have a place we can focus law enforcement on to take those out and perhaps the source of the r.v. from entering the network take note on al-jazeera. a

a skyscraper in moscow. well in all the stories we're following the democratic republic of congo is rejecting the african union's call to delay the final result of last month's disputed presidential election a you won't see announcement to be postponed because of concerns of electoral fraud provisional results declared opposition need to fix this you katie the winner but they are being challenged by his rival modify you do you accuse us to she k.t. of rigging the outcome with outgoing president joseph kabila. has more now from the capital kinshasa. government officials in kinshasa have told the african union that this is a sovereign country no one should interfere no one can tell the d.l.c. how to run the elections they also say they can fees because they getting mixed messages from african leaders we know the african union is unhappy with the electoral process so far but leaders from the southern african development community issued a statement saying that the people of the d r c should be able to resolve their own crisis foreign country should not interfere and people especially its national

committee should wait for an outcome from the courts we know that eight constitutional judges are meant to make an announcement on the way forward they could either say the feeling is the katie won the election which means he will be sworn in as president in a few days time they could order a recount all they could say the whole process was a mess of the ditch and she be held again wish to take months maybe even years and that means it could be the remains of president until those elections are held all eyes of course will be on martin fire you the opposition leader the catholic church has won the election by sixty one percent if he's not happy with the outcome from the court how he reacts if easy to tell his supporters to go onto the streets and protest is no guarantee the concert hall to make announcement friday it could be over the weekend or sometime next week a kenyan court has ruled that five suspects in choose days hotel attack must be held in custody including a canadian national well suspected of helping gunmen who still need us at hotel compound and killed twenty one people based on group says it was behind the attack

just outside his home in accra and what appears to be a targeted killing almost all do is from the north the other families were from this place is all here morning you know it's something very shocking and what people were even intending to do we have big. in moscow come to talk to us not to take the law into our hard because yet we don't know who is responsible. of this unfortunate incident i met worked closely with the award winning investigative journalist and us army together they expose corruption in the gun in judiciary health sector and most recently saw several hours after the killing and asked person to video on twitter showing a member of parliament making threats against ahmed in june last year after the latest exposé on soccer that led to a lifetime ban from the sport for the head of ghana's football association for bribery and corruption has come to. that which we need to do something extra not

the terrible trade in the legal ivory. now. new tools straight from the lab that could find a crime that's brought elephants to the brink of extinction and getting a seizure is a great victory but the elements are already dead. from rita davis and is an environmental biologist i am holding a tray of elephant who should show us the high tech plan to stop the killing. then céline stranded along the california freeway yes freeway doctor should do some more it is a mechanical engineer chill show us what's been done to find out why this is happening at this thanks dave distressed and i'm still taurus i'm an entomologist vamps are team plenty. know it's do some science.

techno on phil toys joined by marie to davison and dr should do some more because there were outlaws out there who are working in the shadows committing horrible acts against defenseless majestic animals we're talking about the ivory poachers who have decimated the populations of elephants in africa and it's really a nominee because ivory guys for about a thousand dollars a pound. than an illegal drugs and you know what that means is that the damage has been devastating over one hundred thousand elephants have been killed in just the last three years and the question is what can we do about it we found a team of scientists that are using some unexpected weapons d.n.a. and radiocarbon dating check it out. april eighteenth two thousand and fifteen. customs intercepts four tonnes of ivory smuggled in being sacks from the democratic republic of congo. it is the largest

seizure in this country's history the ivory on the way to laos seized in bangkok after a tip the seizure makes headlines customs displayed over three tons of confiscated african ivory worth six million dollars a historic bridge from kenya and. nine hundred elephants but the perpetrators of this horrible crime against animals are never caught for law enforcement entities like interpol stopping the killing of elephants at the source is what's critical. the question ends where exactly is all this ivory coming from they almost always shipped the ivory out of a different country from where it was poached because that's where you start your search looking in the wrong place sam wasser is the director of the center for conservation biology at the university of washington. when it comes to solving the mysteries of the illegal trade wasser has created a coalition of scientists virtual detectives using techniques. indian ache

struction from ivory. genetic mapping through dung sampling and radiocarbon dating this multipronged approach attacks a criminal enterprise that's brought the majestic african elephant to the brink of extinction and there's probably only four hundred fifty thousand elephants left so the whole focus of our lab is to really try to use d.n.a. assignment of large overseas. singapore two thousand to six and a half tons of ivory seized the largest in the country's history roughly six hundred fifty elephants were killed for this haul of ivory. but where in africa did the ivory originate from they assume this much ivory must come from multiple sources authorities send samples to washers lab for analysis right now from anywhere in africa we can assign a seizure of ivory closer than three hundred kilometers to where it came from

wasser and his team get to work the first step is to prepare the samples of seized ivory. we cut off a piece of the ivory and then leave we do is we stick that piece inside a plastic tube with a magnet and stainless steel plugs on the end we drop that in liquid nitrogen which cools it to about minus two hundred forty degrees celsius so extremely cold within three minutes it comes out like baby powder. so it's a whole the ivory and it preserves the d.n.a. at the same time that was one of the biggest breakthroughs of our. elephant d.n.a. from the ivory seized in singapore is extracted and analyzed in washers lab the d.n.a. from the tusks is then matched against a genetic reference map of africa's elephant populations this map has been generated by d.n.a. taken from another source rich in elephant d.n.a.

i am her. olding a tray of elephant coop not exactly something you'd associate as a tool for fighting international crime but these samples provide critical pieces of data for creating a genetic map of elephants across africa yup collecting dung samples may not be glamorous work but it's a task wasser and his team take seriously we make the map from the dung we take genetic markers out of the dung samples so you see here this map of africa there's about fourteen hundred total samples here and each sample is from a separate family group loesser was able to determine the origin of the six and a half tons of ivory seized in singapore and shipped out of malawi it all came from a neighboring country zambia. wasserstein had made a discovery that would revolutionize law enforcement's approach to poaching basically the study debunked some of the assumptions that you and interpol had

about how these activities were working what were those assumptions and so as assumptions that law enforcement general had and one was when you get a big seizure they were cherry picked from all over africa and what we showed is that's not what's happening there in the same area over and over and over again. the plight of the african elephant has been well documented these heartbreaking images were shot in a sanctuary for elephant orphans in kenya from before the biggest enemy of elephants when the out in the woods on this two year old being bottle fed stood by his mother's body for three days after she was murdered for her tusks the first to kill the bowls and then you kill the matriarch so now you're destroying the leadership in your group as well as the long term knowledge that these elephants have and when elephants become vulnerable so does the rest of the ecosystem there are these keystone species where you take this one out and it has this huge ripple effect on all these other species elephants are true keystone species.

sophisticated transnational syndicates oversee every step of the trade from the illegal poaching to the smuggling of tusks to carving factories and shops around the world. this footage part of an undercover investigation captures a shipping agent explaining how ivory is smuggled out of africa very wrong or very good. we need an urgent method that stops the killing even getting a seizure is a great victory but the owners are already dead. last month singaporean customs seized another shipment of ivory coming out of kenya and headed for vietnam three point seven tons worth an estimated. eight million dollars singaporean authorities have already contacted wasser to oversee d.n.a. analysis was his lab and now receive samples from over ninety percent of all marj i

have receivers what we are trying to really do is to figure out where are the major poaching hotspots across africa his latest study based on d.n.a. analysis of twenty eight seizures between one thousand nine hundred six and two thousand and fourteen reveals there may be only two major hotspots for poaching in africa southern tanzania and a place known as the tri them. when you're saying hot spots you mean hot spots of poaching activity hotspots of seizure activity what are you referring to a hot spot is a place where you are able to provide multiple tons of ivory repeatedly over multiple years then we have a place we can focus law enforcement on take those out and perhaps choke the source of the ivory from entering the network and unravel it so that's the big plan.

a techno crew member is on vacation in thailand when he comes across this all too common display he's told of their ivory pieces offered up for sale for a price the sale of ivory to foreigners is illegal in thailand yet as our camera reveals it goes on as this old newsreel footage shows ivory was once very popular. across into his own but all that changed in one thousand nine hundred ninety when the international trade in ivory was made illegal. d.n.a. analysis is one tool that could ultimately help government's crackdown on where ivory is coming from but it can't tell investigators when the killing took place anything postin is illegal to. what it comes down to is this this radio carbon dating method can tell us if trade of ivory is legal or not kevin you know is a geo chemist who uses a method known as radiocarbon dating to determine the age of ivory this is the part

of the tusk that was actually growing when the animal was shot because we need to know when did this elephant die and so this part of the tusk tells us that and so we drove the powder on to this wave paper here. and we collect it into these vials next to ivory powder is combusted and turned into pure c o two so what is this we can bust it in this tube it there's other impurities in there other gases we need to get rid of those so that when we measure the radio carbon content we just are measuring the c o two gas radiocarbon dating literally relies on the fallout from the events that took place from one thousand nine hundred fifty two to one thousand nine hundred sixty three. one fire. above ground atomic testing between the united states in the soviet union we've

basically doubled the radio carbon concentration in the atmosphere now what does that mean then for organisms when you have a spike in radio carbon in the atmosphere what it did do is give them all the unique geochemical fingerprint in their tissues all these photosynthetic organisms trees grasses that sort of thing are taking in c o two some of it having carbon fourteen in it and in the animals that eat that then also take on that radio carbon signature look there it is you can actually see it's freezing down on the right side so now we're going to do is torch it off and have the final final product. and bring this to them and you do this individually for each sample yeah this is it's time consuming it's so you want to wear these to to watch this process so this is just a regular methane tour. not to be done at home and eat and warm a glass. all around that it's sort of like. holding soft serve. and it's unique. and now you can

see. there's our c o two right there that's that's the frozen c o two from an elephant heading for radio carbon announces after you know receives the radio carbon content of a piece of ivory he can match it against the bomb curves a record of atmospheric levels of c fourteen before and after the atomic testing era the radio carbon dating a five re could be used to verify the age of ivory being sold on the legal market as antiques but here's the bottom curve and i call this left side before nine hundred sixty three the rising limb so the tusk is imprinted with the radiocarbon constitution from that year so we can and go and measure that radiocarbon concentration and say ok it's for example one point three and that allows us to draw horizontal line across the bottom curve here and you can see it actually

intersects it into place two answers it can be nineteen sixty or it could be one thousand and eighty so the way to do this is to sample part of the test that you know is older and in the part of the house you know it is younger and compare the relative radiocarbon concentrations and just fit them back onto this curve so if the older one has a higher concentration in the younger has a lower than your on this falling limb of the bomb curve november two thousand and thirteen canadian authorities learned that a pair of tusks are being offered by this toronto based auction house as antiques suspecting the tusks are not as old as the sellers claim authorities confiscate them and turn them over to. buy david a pair of tusks clearly showing that his elephant was poached after the law went into effect and. the auction house went to court and pleaded guilty now you know and collaborator turi serling have teamed up with wasser to apply this technique to investigate trends in the international trade in illegal ivory since the

international ban african countries have been stockpiling confiscated ivory occasionally they destroy some of it but much of it remains sitting in government warehouses so they have huge stockpiles on the order of one hundred or one hundred twenty tons and some of these nations they're so they're sitting on this ivory waiting for the day that the international market opens again if current poaching hotspots are shut down the next major source for ivory could be the stockpiles and radiocarbon dating would help confirm it to what extent do you wrestle with despair at the situation and to what extent do you embrace hope and there have been some seizures where i got to say you know when we pulled them out and started rinsing him off in the blood was pouring out of him that we were just sitting there in tears i mean you know that that has happened but you know you get. used to it and and then you start getting these breakthroughs and so no i feel like you know

we've got a plan i feel like we're making and in there and that's really what drives me. to steps of d.n.a. techniques that you talk about that practice has been done for a long time to maybe track the origin of the disease what took him so long to get through tracking down poachers you know we've used d.n.a. techniques to understand populations of lots of wildlife we're using it within the context of conservation a lot more now it's still a fairly new field so there was a time when ivory was used in canada and believe it pools and now it's illegal but why is the market still so robots the main markets are in china and then actually the united states is the second largest player here part of what's driving that is that there's some. communities in the us that really value ivory iris you mostly find it as an ornamental carving it's very beautiful when it's polished and carved and it carries a sort of status because of its values so there's still

a pretty high demand there is a crisis unfolding on the coast of california from san diego up to san francisco and beyond sea lions are leaving their natural ocean habitat and wandering up on shore even sometimes in people's yards and streets well i joined a ride on my we were literally rescuing sea lion pox the story is crazy some of it's heartbreaking and it's coming up that. this punk named johnny cash is making a run towards the open ocean with a satellite transmitter tied to his back he may hold the on says to a sad epidemic among california's coastline. there are plenty of highways that hug california's ocean shores and he's ninety freeway isn't one of them the sight of a baby seen a quarter of a mile inland is unsettling. but in two thousand and fifteen it's not that unusual

according to local news agencies the creatures are stranding starving and apparently dying in record numbers this year along the coast the images tell us a haunting story well we have seen spikes and rethink years two thousand and fifteen is already off to an unusually start the headlines paint a picture of an epidemic of sick pops in desperate search of food but what's really going on is more complex techno went to the san diego headquarters for a federal agency that studies the oceans says ports happened in the last two years is the waters in the northeast pacific have warmed up way beyond anything more used to according to noah a warm up ocean off southern california has made it hard to finance things. the lions to forage and as a result the pups are not getting enough nourishment el nino is an event scientists have seen several times but this year's temperature is

a quite different what's really different is that the waters in the northeast pacific warmed up over a year ago and usually that warming occurs after the only no developed in this case that preceded it ocean warming impacts the food chain from the bottom up as upwelling wins a causing deep water currents typically rife with cold water nutrients to secularize up mostly nutrient depleted warm water so when you talk about nutrients what is that that biologic material in the deep ocean gets remember allies tend to work in organic nutrients and so the upwelling them keeps that cycle going so how does it affect the top of the food chain the whole food chain gets depressed a lot of the those fish species that could move have moved northward and a food source there's a lot less than we had last year and the evidence can be seen daily all along the california coast from san diego to san francisco in san diego sea world the company which face public heat for. has taken

a public role in sea lion rescue efforts. it's really a new thing i was lucky i think yeah this how long do you feed them for typically it will be two painting for about twelve days and about five days they have gained enough strength to actually start showing some interest again and pressure and they will start taking water to fish sea lions a facet method to an almost tree asure like setting the pups to fed a special protein which formula up to two hundred feedings a day take place behind the scenes we have to gradually read about it because their bodies haven't seen fresh and they can't process it properly they have to show it to us that they can afford process three to five pounds of fish per day which is what they would require to maintain their weight before we stop to feed brands to it observe sea lion health at sea world's nonprofit research on. so in studying their habitats you able to get a better idea of what's happening in terms of global climate change food seem to

have vanished for some reason the question is whether that's a sign i think of long term climate change the bigger issue is are these little intensive answered we're seeing recently going to become more common as climate generally changes according to the national marine fisheries service is the west. as rescued pups are returning starved again it is the most historically busy year ever of this argument twenty five hundred sea lions stranded in california this year alone in the first twelve weeks that we're into the year marine biologists and executive director of the pacific marine mammal center a key from a tosser has seen it all but. they're actually six months old coming into us under birthweight that's how starved they're the other difference in this year that we didn't see in twenty thirteen and twenty forty is that we're now seeing a lot of adults coming in that are very me seated very star you can see every bone
