this is the mass in that world where the students were attacked. at the beginning, i think we couldn't understand what really was happening with the missing students of iguala. it was like another story about violence. my name isjose and i'm a journalist and i do photography, i do video. as mexican journalists, we learn a lot from the other investigations. we learn how they move and how they manipulate the evidence. the corruption has become a normality for us. we are very suspicious about everything that the government says. the morning was interesting because now, we have a lot of soldiers, a lot of marines patrolling the area. when we arrived to the cocula all the dam, they closed the road. they didn't allow us to cross this point. they tell us, "get out of here. "you don't have

nothing to do here. "this is private." isaid "no, no, no. "you can't kick me out. "i'm a journalist. "i have the right to be here." they start to organise a convoy with marines and members of the police. it looks weird, the whole thing. so, i start to make camera from a long distance. and i start to follow them. and they came into the rio sanjuan and they start to look for something. myjournalist instinct tells me "stay here, don't move". because something is going to happen here. at the same time, tomas zeron flies from mexico city to cocula with one of the detainees who had confessed to the killings. at the same time, tomas zeron flies from mexico city to cocula with one of the detainees who had confessed

to the killings. the search at the river on the 28th of october would become a contested part of the government's investigation.

this is the afternoon of that day, the 28th. this is like one, two hours after zeron has left the scene. this is the forensic team. they are making an inspection in the riverbank, picking up small things and putting them

in forensic bags of evidence. at that point, forensic argentina group arrive and i thought the guys with the white suits were working with the argentinians. later, i knew that the argentinians didn't have any idea what was happened just a couple of metres below them. and it was obvious that they were having an argument. we came down from the garbage dump a little bit earlier. we were stopped at the road in cocula that actually borders the rio san juan.

one of the prosecutors was there — one of the federal prosecutors — and he blocked with his pick—up our way. and he said, "you can't pass right now. "there's an operation going on. "you can't continue. " we were like, "what on earth is going on here?" at that time, we didn't suspect much, so we waited in the cars for a while and then, they let us pass, and that was it. the next day on october 29, one of the federal prosecutors came to the garbage dump and said, "we have "another site. "you should come now." and that's when they took us to the rio sanjuan. we realised when they took us to the rio san juan that that was close to the same spot where we had been stopped the day before. there were already federal forensic experts next to the river.

they were extracting from a plastic bag a black bag, like a garbage one. they told us that that bag had been recovered by scuba divers that were inspecting the river. and then, i saw one fragment of bone that was, you know, considerably larger than what we were seeing at the garbage dump in cocula and almost not damaged by fire and so, i thought "well, if there are more remains "like this, we may be able at least to extract "dna "like this, we may be able at least to extract "dna and compare it against the dna of the families." by then, as i said, we had worked on a number of cases in mexico where forensic evidence had been tampered with and you're constantly

asking yourself what part of the evidence can you trust? and so, when we go to the rio sanjuan and see this fragment that is way larger and almost not burnt, it's like, "this is very different from everything we are seeing." we were not there when the bag was taken allegedly out of the river and we were not there when the specific

my name is omar gomez trejo and i'm the former prosecutor of the case in mexico. in the months after the boys went missing, civil unrest grew. in december, 100,000 people marched through mexico city to protest their disappearance.

in january 2015, the attorney general announced they had found a dna sample that matched one of the missing students.

the government said the case was closed and that the dna from the bone in the river matched missing student alexander mora venancio, confirming their account, which they described as "the historical truth". in this official version, the students left the iguala bus terminal in four buses. corrupt local police working for the mayor and a local drug cartel had attacked them and detained the group of 43. cartel gunmen murdered them, burning their bodies

at the dump and throwing their ashes into the river sanjuan.

for us there is no scientific evidence to establish the official story. whoever knows where that fragment is coming from knows something about where the rest of the remains of the students may be. it holds the key to a lot of information.

in april2015, omar gomezjoins the team of independent experts as their local assistant.

the story of this fifth bus become central to the whole story because it is such an anomaly. this is the only bus that was not shot at and only of the five buses that the students were on that will leave the city that night. it is also a bus that the federal government will lie about constantly. we knew with certainty that we had cracked into a major criminal organisation with direct ties to guerrero.

hello. full uk forecast in a moment. first of all, i thought i'd reflect on storm ingunn that came across the north atlantic wednesday and hit sweden and norway wednesday night, bringing what looks like being record—breaking winds, sustained winds of 122 miles an hour, parts of norway, and 116 miles an hour in sweden. unimaginable strength

of the winds. there were even stronger gusts. the gusts that we recorded were even much stronger than those that hit southern england in the great storm of 1987 — one of the most powerful storms i've ever seen, storm ingunn. now it's the lovely end to the day on thursday, fine sunsets many of you spotted caused by the clear skies illuminating the cloud out west. but it is the cloud that's going to be winning the battle, i suppose, over the next few hours, progressively turning quite cloudy, a few patches of drizzle around, some rain into western scotland, but very mild air, again flowing in off the atlantic. we see high pressure to the south, weather fronts to the northwest where it will be windy. gusts of wind reaching 50 odd miles an hour across northern scotland, where it'll be damp and drizzly across western areas. elsewhere, a lot of cloud to start the day. but given its quite windy, i suspect we will see some sunny breaks breaking through across parts of east scotland, to the east of the pennines, probably eastern parts of wales, and maybe eastern side of both antrim and downs. so you might see some glimmers of sunshine. either way, it will be a very mild day. the air gets a little bit

cooler across northern areas on saturday, say cooler, temperatures coming a bit closer to average, sunshine and showers working in here. again, it's quite blustery. england and wales having the thickest of the cloud with some patches of light rain coming and going. temperatures 14 degrees, again, well above average for this time of the year. the average in london is nine degrees. for sunday's forecast, again, we've got the mild air with us, but thicker cloud this time, so probably a higher chance of seeing some damp weather at times. the far north of scotland, again, quite blustery with some showers working in here. for most of us, temperatures again on the mild side, ten to 14 degrees pretty widely. but then after this mild run of weather, might be something of a shock to the system to see the weather turns a lot colder next week. and for some of you, that means a return of seeing some snowfall. now it's a little bit less certain just how cold it gets further southwards across england and wales. but it could be that we see some snow. for the time being, the models are picking up thick cloud with outbreaks of cold rain at times.

live from washington, this is bbc news. the us imposes sanctions on jewish settlers who've carried out violence in the occupied west bank. israel's prime minister says the measures were unnecessary. a gas plant explosion in kenya's capital lights up the night sky. witnesses told local media they felt the ground shake after the blast. a food fight brews in brussels: farmers take their ongoing protests over regulation and cheap imports to an eu leaders summit. hello, i'm caitriona perry.

you are very welcome. we begin the program with two new developments from the biden administration in dealing with events in the middle east. first, presidentjoe biden has approved sanctions on four israeli settlers accused of attacking palestinians in the occupied west bank. biden signed an executive order saying violence in the region had reached intolerable levels. israeli prime minister benjamin netanyahu says the vast majority of settlers are law abiding, but that israel takes action against law—breakers and there was no need for the measures by washington. violence against palestinians in the west bank has spiked since hamas launched an unprecedented attack on israel on october 7th. the united nations estimates about 370 palestinians have been killed in the west bank since then. here in washington, the us state department urged israel's government to do more to stop the violence against civilians. there is no justification for extremist violence
