this is the world today from bbc news, the headlines president biden signs the law to provide military assistance for ukraine, israel and taiwan. british police arrest three people in connection with the deaths of five migrants in the english channel on tuesday. the former leader of the dup sirjeffrey donaldson appears in court — charged with sexual offences including rape. and what happened when four military horses broke free and galloped across central london. there were extraordinary scenes in london this morning when a group of military horses threw their riders and bolted through the streets leaving

four people including a cyclist in hospital. our correspondent ellie price takes up the story. if it wasn't so dangerous, it would be strangely beautiful. two military horses on the run in central london during the morning rush hour. one hits a taxi. and they carry on down fleet street. in total, five household cavalry horses ran loose after unseating four riders. one had been in charge of two courses. the damage unmistakable as they crashed into several vehicles, including this bus. three soldiers were hospitalised, their injuries not deemed to be life—threatening. the bbc understands a fourth person injured was a cyclist. at such a busy time in the day there were of course plenty of witnesses. as i looked to the left i saw two horses coming towards me and i ran to get across the road.

they are big horses and the grey or white one had blood from its weathers, its shoulders. it was coming at such a speed, i thought i need to stop those horses. two horses went past me and i saw them gallop without riders, which was quite extraordinary. i checked it was safe to pull out and another horse came around the corner with a rider on it and just missed my cab. pictures on social media showed members of the public catching and calming one of the horses. all five have now been caught and are being checked over by a vet. the chaos started to unfold near buckingham palace this morning. the black and the grey made it clear to the strand before ending up five miles away at limehouse in east london. we understand it was noise from a nearby building site that causes the horses to spook and balls and they unseated their riders and one of the loose horses crashed into the taxi just about here. household cavalry horses are used to loud noises

and the challenges of central london. many of their stablemates were involved in the changing of the guard this morning. tonight all five horses are back at the barracks near hyde park. questions remain over why they were so spooked. earlier we spoke tojeanette allen — she's worked with the household cavalry — the regiment the horses belong to — for over 13 years. she started by giving her view on what might have startled the animals. the reality is, with all the training of the world and these horses have an enormous amounts of training, to desensitize themselves of these kinds of noises, you cannot predict everything that a horse can experience while in the city and what i understand, it is very large amount of concrete being sent on the plastic builder sheet and that is not something they would've trained for. a big noise coming down words

of different university campuses. there have been pro—palestinian demonstrations and protests by students across the us in different university campuses while they're still making their voices heard, protesting against the situation in gaza and the war there. let's go to austin, texas. it is somewhat of a confusing picture but pro—palestinian protesters there and this is the university of texas campus and as you can see there, security personnel and officers on horseback and we have been keeping across these pictures for the past few minutes. but it is notjust austin, texas, want to show you different live feed coming from the university of southern california. these pictures here on campus been

carrying that tent across the grass and lots of tense being moved around there, lots of chanting but we haven't seen any clashes as of yet we have been monitoring for the last couple of moments and a third feed from new york this is columbia university. this is been the headlines and arches students arrested there last week in order to leave and take the stance down, go. you can see the tents are still there and they're in discussion with university staff there about what happens next. protests against the war in gaza but also specific demands by students in different universities locations and they want the university to divest in the between what is going on in israel. in the university of southern california, there seems to be a bit

more from it now and that's just take a listen and. whistles blowing we are going to stay on these pictures arejust a we are going to stay on these pictures are just a moment and clearly, apologies if there are any bad language used. which is going to stay with these skirmishes, it seems that the moment, nothing more than that.

if you're just if you'rejustjoining us, this is the university of southern california, pro—palestinian demonstrations taking place across the us. protesting against what is happening in gaza and students in many different locations with specific demands of the universities wanting them to divest from financial interests relating to israel. we have seen some skirmishes, i think is probably the most accurate word at the moment this it been monitoring these positions of the last few moments. crowd chants "shame on you!"

so, it looks like one of the protesters is being taken away where the organisers in the bid there, potentially urges the student on campus being taken away.

crowd chants "let him go!" directed towards the security police taking him away. crowd chants "let him go!" so, let us take you to the other campuses that we have live feeds coming into the building here. this is austin, texas. we have seen the

officers there on horseback and again, as we have been monitoring these live feeds of the past 20 minutes, we have seen certainly skirmishes, some physicality but we haven't seen anything more than that and of course, we can only speak to the images we have seen. and to share what is happening in new york, the tents that have been in columbia university asking for these tens and telling them to go in there very much store their negotiations between students there and authorities at columbia are ongoing in those three live feeds of clearly higher than the opinions and views in temperatures there pro—palestinian demonstrators across many campuses across the us it would keep them across and keep an eye on

all those feeds and we come back to as and when there are developments. let's turn to portugal now. president marcelo rebelo de sousa says his country must take full responsibility for colonial—era abuses. he also says there are circumstances when reparations should be paid, such as when massacres took place under colonial rule, or where significant items were looted and never returned. let's crossover to lisbon — and speak to paula cardoso, a portuguese activist and founder of the afrolink online — a platform for black professionals in portugal thank you for coming on the programme. thank you for coming on the programme-— thank you for coming on the programme. thank you for coming on the rouramme. h, ., ., ., ~ programme. good evening and thank ou for programme. good evening and thank you for having _ programme. good evening and thank you for having me — programme. good evening and thank you for having me here _ programme. good evening and thank you for having me here to _ programme. good evening and thank you for having me here to comment. programme. good evening and thank i you for having me here to comment on this remarks about reformations. what is your reaction was shallow last year, they said that portugal should apologise and fred's past and

what are we waiting for? share the power and means to do it and so, what are we waiting for?— what are we waiting for? are you confident you — what are we waiting for? are you confident you will _ what are we waiting for? are you confident you will get _ what are we waiting for? are you confident you will get what - what are we waiting for? are you confident you will get what you l what are we waiting for? are you . confident you will get what you want soon? ., . , confident you will get what you want soon? ., ., , , , ., soon? not really because what i see is superficial — soon? not really because what i see is superficial way _ soon? not really because what i see is superficial way of _ soon? not really because what i see is superficial way of breaking - is superficial way of breaking this topic forward is making it harder to discuss this carefully and this is a strategy to avoid the proper conversation it if the president is so invested in reparations, he should start by listening to those who suffer directly from this heritage, mainly. but every time a single black person in portugal tries to start the discussion, this person is being dismissed. so, there is less difference between words and actions and not only words. thank

the worlds largest 3d printer has been unveiled by the university the world's largest 3d printer has been unveiled by the university of maine. dubbed the �*factory of the future 1.0', the machine has been created in order to tackle the us homelessness crisis — by printing affordable housing. let's speak to dr habib dagher, he's director of the advanced structures and composites center at the university of maine. how big is this thing? it is able to rint how big is this thing? it is able to print things _ how big is this thing? it is able to print things roughly _ how big is this thing? it is able to print things roughly 100 - how big is this thing? it is able to print things roughly 100 feet - print things roughly 100 feet long and about seven feet high around 26 orseven and about seven feet high around 26 or seven feet high. it is pretty big and what is going to do? all sorts

of things. but among the big problems are trying to tackle is the lack of housing, affordable housing in the united states and in the us, we have 9 million homes that are needed right now state of maine where we live we need 30,000, 80,000 homes paid 2030 and a big issue is we do not have the labour to do that, the costs homes sway to high. painting with renewable materials, would waste if you wish, to produce his homes. ~ ., would waste if you wish, to produce his homes-— would waste if you wish, to produce his homes. ~ . ., ., , his homes. what are you, or you 'ust squirting things fl his homes. what are you, or you 'ust squirting things backi his homes. what are you, or you 'ust squirting things back over i his homes. what are you, or you 'ust squirting things back over and h his homes. what are you, or you just squirting things back over and over. squirting things back over and over and how does it work and what is actually made of? that and how does it work and what is actually made of?— actually made of? that is exactly riiht actually made of? that is exactly ri . ht and actually made of? that is exactly right and think _ actually made of? that is exactly right and think of _ actually made of? that is exactly right and think of it _ actually made of? that is exactly right and think of it as _ actually made of? that is exactly right and think of it as a - actually made of? that is exactly right and think of it as a tube - actually made of? that is exactly right and think of it as a tube of. right and think of it as a tube of toothpaste and it's doing it close toothpaste and it's doing it close to £500 per hour and this is not your normal toothpaste tube. it's

more like a fire hose what is doing is laying down materials one layer at a time the materials were using her with materials in the state of maine where the most heavily reinforced it and we lost about five paper mills a few years ago so, we have a lot of wood residuals and would waste from our sawmills that has no place to go and write 1 million tonnes per year in the state of maine and that will produce such thousand 600 square—foot homes extraordinary images we have been looking at and just briefly, how cheaply can you build a house? the ioal is to cheaply can you build a house? tte: goal is to compete cheaply can you build a house? tt2 goal is to compete with existing technologies and we have reasons to believe that will be below the cost of existing housing and the important thing is we don't have the people to build homes today and that

is the issue is a lot of people cannot buy a home or rent a home simply because we don't have the people to build them, we have the money butjust people to build them, we have the money but just at the people people to build them, we have the money butjust at the people to do it in the grand automation, will allow us to make a dent in this housing crisis.— allow us to make a dent in this housini crisis. ., ., , ., ., _, housing crisis. thank you for coming on and explaining — housing crisis. thank you for coming on and explaining it _ housing crisis. thank you for coming on and explaining it to _ housing crisis. thank you for coming on and explaining it to us. _ back to the us. let us go to austin. pro—palestinian demonstrations taking place through different locations of the moment they were to begin a cross for you this is bbc news. will be back in the us a little bit later. next, we are going to talk about plato.

plato — ancient greek philospher. an italian researcher says he's found where plato was buried. apparently, he's buried in a garden near the shrine of the muses in athens. how did they find that location? looking at ancient papyrus scrolls that were carbonised when the town was engulfed by the eruption of mount vesuvius in seventy—nine ad. they could only be read using a bionic eye. let's speak to graziano ra—nokia he's professor of papyrology at the university of pisa who's leading the team who made this discovery. thank you for coming on the programme. how did you find the burial location of plato? bi; burial location of plato? by nickini , burial location of plato? el: nicking, the history of the academy and is prepared and published by a doctor and establish some weeks ago

seeing sunny spells and showers — still some wintriness in those showers over high ground in scotland, and temperatures in a range between 8—13 celsius, so below par for this time of year. through thursday night and into friday, it looks like we'll see this weather system here just grazing the south of england and the channel islands, so that will bring some cloud, perhaps some showery rain here through the day. elsewhere, it is another sunny—spells—and—showers day. still some wintry showers in those showers over the hills and mountains of scotland, and those temperatures for most between 8—12 celsius. now, as we head into the start of the weekend, for most, it'll be a cold morning on saturday, it's another sunshine—and—showers day. but turn your eyes to the south — an area of thicker cloud and some outbreaks of rain pushing across the channel islands, into southern counties of england through saturday afternoon. with that, temperatures will start to lift a little — 1a celsius in london. and that is the story of the weekend weather, some slightly less cold air beginning to spill its way up from the south. certainly not going to be a heat wave, and it's certainly not going to be completely dry, because that slightly—less—cold air is being brought our way by this area of low pressure. looks like we will see some outbreaks of rain continuing on into sunday,

particularly across england and wales. the chance of seeing something drier and brighter for northern ireland and scotland.

hello, i'm christian fraser. you're watching the context on bbc news. the graves are now at the centre of conflicting claims between hamas and local aid workers on one side and the israel defense forces on the other. hamas claims some of the dead were executed, had their hands tied and were dumped in mass graves. the examination was carried out respectfully while maintaining the dignity of the deceased. bodies were examined which did not belong to israeli hostages, and they were returned to their place. we are horrified also - by the instruction of al nasser —— we are horrified also - by the destruction of al nasser medical complex and al shifa - medical complex and the reports of the discovery of mass graves in and around facilities. - and we call for independent, effective, transparent - investigations into the deaths.
