hello, i'm christian fraser. you're watching the context on bbc news. tiktok says it will challenge in court — a new law that could see it banned or sold in the united states. now for sport and for a full round up, from the bbc sport centre. hello from the bbc sport centre. a busy evening of football in the premier league to update you on first, with liverpool hoping to move back level on points with arsenal, who sit top of the table. they're at goodison park for the merseyside derby. that's one of four matches happening. everton 1—0 liverpool, jarrad branthwaite with the goal. a crucial match forjurgen klopp�*s

side, in the title race. they need to get back into that match. everton need the points too, as they battle to avoid the drop. wolves 0—1 bournemouth. antoine semenyo. crystal palace 0—0 newcastle, manchester united 0—0 sheffield united. former argentina international carlos tevez has been admitted to hospital after suffering from chest pains. the ao—year—old former manchester united, manchester city and west ham striker was taken to hospital in buenos aires on tuesday and will remain there until medical tests are completed. tevez, who won 76 caps for argentina, took over as manager of independiente in august last year. the former world no.1 naomi osaka has won her first match of the clay court season at the madrid open, beating belgium's greet minnen. osaka won in straight sets, 6—4, 6—1. it was only her second match on clay since going out in the first

round of the french open two years ago, and herfirst win on the surface since then. emma raducanu's progress in stuttgart last week failed to count for much. she collapsed to a straight—sets defeat to maria lourdes carle at the madrid open. having made it to the quarter—finals at last week's tournament in germany — that encouraging form deserted her, as she was defeated 6—2 in the first set by her argentinian opponent, who is ranked 83 in the world. the 2021 us open champion wasn't at her best on the clay by any means, losing the second set by the same scoreline. jack draper though is on to the second round, after beating the australian thanasi kokkinakis on a decisive 3rd set — it finished 6—3, 3—6, 7—5, he will now move on to face hubert hurkacz on thursday. some news to alarm rafa nadalfans though — he says he's not sure if he will be able to play at next month's french open after pushing through the pain barrier in his comeback from injury.

the 37—year—old, who is a 22—time grand slam champion, said that he is farfrom being in top form and that he's only playing in the first round of the madrid open on thursday as a personal sacrifice. nadal, who has said he expects to retire after this season, returned to competition in brisbane in january after almost a year sidelined with a hip flexor injury, but hasn't played consistently since. ronnie o'sullivan made a fine start to his bid to win a record—breaking eighth world title as he dominated the first session against welsh qualifierjackson page. o'sullivan is looking to move clear of stephen hendry�*s seven crucible successes and holds an emphatic 8—1 lead over 22—year—old page, the world number a3. o'sullivan needs to win only two frames when the match resumes on thursday. meawhile, china's ding junhui is out after losing the deciding frame in a dramatic first round match against the world number 17 jack lisowski. a clearance break of 131 from ding, who was runner up here eight years ago but has never won the world title, levelled the match at 9—9.

but it was the englishman, lisowski, who came out on top in that final frame — to set up a meeting with stuart bingham in the second round. and that's all the sport for now. we will keep you up—to—date with everything that goes on in the football a little later on. a little earlier in the programme we talked about the ukraine passage which passed the senate last night. attached to it is a bill that would ban tiktok in the united states or force the chinese owner bytedance to sell it within nine months. the us government says it has concern that tiktok might share that user data with the chinese government — claims it has always denied. the company's ceo, said today bytedance will take the us government to court. make no mistake, this is a ban, a ban on tiktok and ban on you and your voice. politicians may say otherwise but don't get confused, many who sponsored the bill admit a tiktok ban is the ultimate goal. so, how would a ban work,

what precedent could it set and how long might all this take? professor anupam chander is a visiting scholar at the institute for rebooting social media at harvard university he is an expert on the global regulation of new technologies. just the man. professor, they are suing as expected. but on what basis? , , , ., basis? they will sue based on their first amendment _ basis? they will sue based on their first amendment rights. _ basis? they will sue based on their first amendment rights. tiktok - basis? they will sue based on their first amendment rights. tiktok is i basis? they will sue based on their. first amendment rights. tiktok is an american company and ask any person inside the united states, it has first amendment rights. also its users will sue and they will claim that there rights are being violated. it clearly is substantial intrusion upon free speech rights. the question the courts will ask is, is that intrusion dust notjustified by national security concerns at the administration alleges. let’s by national security concerns at the administration alleges.—

hard—fought case with very unpredictable results. you hard-fought case with very unpredictable results. you talked about the first _ unpredictable results. you talked about the first amendment - unpredictable results. you talked i about the first amendment defense. of course the government will talk about user data, privacy and the concerns of the national security agencies have about this. irefill concerns of the national security agencies have about this. will that feature prominently _ agencies have about this. will that feature prominently in _ agencies have about this. will that feature prominently in the - agencies have about this. will that feature prominently in the case? l feature prominently in the case? absolutely. the government will argue that any impingement upon the free exercise of speech rights by the americans is to be justified free exercise of speech rights by the americans is to bejustified by the americans is to bejustified by the harms of allowing this app to continue as it currently is in the united states. and they will say basically that leaving the app as it is in the hands of largely chinese owners puts americans personal and national security at risk. haw national security at risk. how invested will _ national security at risk. how invested will other _ national security at risk. how invested will other us - national security at risk. how invested will other us companies be invested will other us companies be in this? this is pretty unprecedented style. if the sale was

ordered then you would think there would be some tit—for—tat for the american companies have precious intellectual property in china which they would want the chinese government to get their hands on. many people in the united states know that china has already banned a bunch of apps from the united states, information services like the new york times or like facebook or twitter. and even wikipedia. there is a lot of other companies that still operate within china. companies like apple and microsoft seldom even companies like tesla. all of these companies collect a huge amount of information about chinese citizens. so they could face blowback in china. but also there is a risk that other countries could borrow this same model to not only ban a foreign app but simply say,

no, we would rather not band that you we just want to have you turned the keys over to someone local. we've seen a bit of that in russia since the invasion of ukraine. in the us who would buy it? there's a whole pile of regulation coming down the track. there are companies may be interested in buying tiktok if they have the technology and the financial clout. then you are talking about one of the big three orfour and then you're talking about one of the big three or four and then you're into questions about the monopolising of the market. w , questions about the monopolising of the market. , ., �* ., the market. exactly. you've got serious antitrust _ the market. exactly. you've got serious antitrust problems. - the market. exactly. you've got| serious antitrust problems. that will mean that the most significant internet companies likely will stay there hand. companies like google and not talk and apple will likely not want to enter into the game. in 2020 we did see microsoft make moves to say, we're interested and we would've been a great owner of this intellectual property. microsoft

does not have a social networking app. today the idea of the current giant might extend its tentacles even further into another social networking space probably will be met with frowns in washington, dc. i would suspect that microsoft two would suspect that microsoft two would stay its hand. we will see. as other entrepreneurs or big financers, we seen former treasury stepped forward to say he is assembling a coalition to buy the act. , ., act. interesting for the fire sale. professor anupam _ act. interesting for the fire sale. professor anupam chander, - act. interesting for the fire sale. i professor anupam chander, thank act. interesting for the fire sale. - professor anupam chander, thank you for coming on the programme it is been hugely helpful. closely linked to that china — the news here in europe this week that chinese spies have infiltrated key government departments. there were two arrests here in the uk.

christopher cash, a uk parliamentary researcher and another man. both charged with spying for china, allegedly providing information which could be "useful to an enemy". and then in germany, the top adviser to a far right politician was also arrested. maximilian krah, is a key member of the alternative for germany. his assistant, jian guo, is a german national who had worked for krah since his election to the european parliament in 2019. he is accused of passing sensitive information on negotiations and decisions within the european parliament to the chinese intelligence service. christopher steele is a former british intelligence officer. worked for the russian desk at mi six. good to see you, chris. it's extensive which begs the question, do we know the full scale of it? ida. do we know the full scale of it? no, i don't think— do we know the full scale of it? no, i don't think we _ do we know the full scale of it? iifr, i don't think we do. this is possibly the tip of the iceberg. i think it's very significant that china in particular seems to be

adopting a much more aggressive and direct intelligence effort against western institutions for the particularly the fact that they are going directly at our political systems and also i see echoes of russia's playbook here in terms of targeting the far right parties in europe for potential sources and agents. europe for potential sources and auents. ., , agents. one of the due rested here, christopher— agents. one of the due rested here, christopher kash _ agents. one of the due rested here, christopher kash was _ agents. one of the due rested here, christopher kash was employed - agents. one of the due rested here, christopher kash was employed by l christopher kash was employed by alicia kearns, the conservative chair of the foreign affairs committee. he was charged with providing information to a foreign state. the question i had about him is, was invented by the intelligence services before he took the job? is, was invented by the intelligence services before he took thejob? i services before he took the job? i think it's very difficult in a situation like parliament where there are 600 mps in 800 lords to actually vent people properly. we know the vetting system has been under quite a lot of financial pressure in the uk of late. the entity that is probably no other

than a cursory look at whether he for example would've had a criminal record. i think this is the worry and think that somebody so young being allegedly recruited by the chinese could well be a long term prospect for them in terms of his ability to network and move about within the political system here. how does it work? how they picked up at universities, other giving grants and tied into the chinese, how are they getting their claws into these people? i they getting their claws into these eo - le? ~ . , people? i think it varies. obviously. _ people? i think it varies. obviously, the _ people? i think it varies. obviously, the ones - people? i think it varies. obviously, the ones like | people? i think it varies. . obviously, the ones like the people? i think it varies. - obviously, the ones like the one in germany where it seems that although his adjournments citizen he's chinese, probably through family ties into asia or china. also people travelling to china, students are vulnerable to be targeted and recruited in this way. my understanding without wanting to prejudice the cash case is that he actually spent a considerable amount of time in china before this

happened. of time in china before this happened-— happened. the head of the counterterrorism _ happened. the head of the i counterterrorism commander happened. the head of the - counterterrorism commander at the met said there'd been an extremely complex investigation why so complex, how did these investigations tend to work? i think there's a great _ investigations tend to work? i think there's a great deal— investigations tend to work? i think there's a great deal of— investigations tend to work? i think there's a great deal of difference i there's a great deal of difference between having counterintelligence and human intelligence on a particular person or situation. and being able to produce evidence in a court of law. what's striking about this is that these guys have actually been charged now. and will go to court and evidence will be presented to show that they were allegedly working for a foreign power. that's a step forward and it indicates how aggressive the chinese are for the interestingly russia is at war effectively so you would expect russian espionage to be strong and aggressive in risk carefree in terms of risk. you wouldn't really expect china. i actually think the chinese are

beginning to look more like the russians in terms of their human intelligence operations now. since ou talked intelligence operations now. since you talked about _ you talked about counterintelligence, counterintelligence, counterintelligence evolves to the threat, whether it's islamist, russian, do you think the european authorities are good at tracking chinese espionage? it’s authorities are good at tracking chinese espionage?— chinese espionage? it's a very difficult question _ chinese espionage? it's a very difficult question to _ chinese espionage? it's a very difficult question to answer. . chinese espionage? it's a very difficult question to answer. i | difficult question to answer. i think they are not used to the chinese working in human intelligence operations of this type. china traditionally has been much more interested in hacking operations and the theft of intellectual property. i think the lessons they've learned from russia will have to be applied to china pretty quickly in order to get this thing under control. it looks at the moment there is a plethora of these things and it is not being controlled by the security authorities at home. for coming on. around the world and across the uk, this is bbc news.

welcome back. there were some extraordinary scenes in london this morning a number of horses from the household cavalry which were on exercise in belgravia, threw their riders and bolted through the streets leaving four people including a cyclist in hospital. our correspondent ellie price has 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 horses. 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 the sources. to stop the 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 here 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 caused 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. good to hear the horses are well. the best of those who were injured today. we have been covering the pro—palestinian campuses across us universities. the scale of that unrest is beyond anything we've seen since the war began. let me show you some pictures from the university of southern california with the police have taken a much more robust approach to the sit ins. similar scenes at the university of texas. that's the

university of texas. that's the university and austin, texas. you can see the riot police on patrol. it feels like it's snowballing. like a national movement at the moment it is dragging in the politicians. a lot of focus has been on columbia university. let's show you live pictures from the main campus where we're expecting speaker the house mike johnson we're expecting speaker the house mikejohnson to speak. he's been speaking in the last few minutes with the jewish students speaking in the last few minutes with thejewish students there. he's expected to give some details on what he's the protesters who set outside of the main faculties, more than 100 were arrested last week put up than 100 were arrested last week put up the jewish than 100 were arrested last week put up thejewish students at this campus, indeed faculty members themselves who are jewish campus, indeed faculty members themselves who arejewish have complained that criticism of israel's policies has now veered into anti—semitism and it's becoming more threatening. the university held a meeting with students today

to come to some accommodation. for the remainder of the semester we're told they will be holding some of the lectures online. we're expecting emma vardy who is on her way to the university of south carolina. let's dive around some of these live pictures as we wait maybe for the speaker to appear at the microphone. this is texas. it's a bit kalmar thenit this is texas. it's a bit kalmar then it was just an hour ago. obviously, when you're talking about young people who form such an important part ofjoe items coalition and a national moment we met movement which is growing, politically it is dangerous for the for the emma vardy, where are you near the campus of university of california where we scenes of violence in the last hour or so. i’m

violence in the last hour or so. i'm headin: violence in the last hour or so. i“n heading towards it. there have been these clashes with police on the campus. we understand there was some tents pitched at all the demonstrators gathered had been warned to disperse. their sense has been escalation and clashes with police. also the university has to some degree anticipated these tensions and has anticipated what might develop with these protests. because of that they had cancelled graduation speeches today. in an attempt to ward things off or calm tensions. a lot of this has been quite inflammatory on social media. both with information and social media material also helping to ramp up media material also helping to ramp up protests and ramp up tensions in terms of the israel and hamas war. we also saw something similar in texas where police detained at least ten people, we understand after huge protest bear at the campus in austin. we understand that the test

was in support of two palestine for the students were asking for the university to stop its relationship with manufacturers who supply weapons. and in a similarfashion it seemed the protesters were detained at the police had asked him to disperse. what's really raising eyebrows is that there were officers in riot gear present at the scene for the people questioning whether it was a heavy—handed approach when it was a heavy—handed approach when it comes to unarmed protesters. there's been a lot of debate about that with people seeing these pictures too. i that with people seeing these pictures toe-— that with people seeing these pictures too. i said it's starting to feel like _ pictures too. i said it's starting to feel like a _ pictures too. i said it's starting to feel like a national - pictures too. i said it's starting i to feel like a national movement. pictures too. i said it's starting - to feel like a national movement. do you think it is connected through social media?— you think it is connected through social media? that is undoubtedly art of it social media? that is undoubtedly part of it because _ social media? that is undoubtedly part of it because movements - social media? that is undoubtedly i part of it because movements these days are absolutely connected organically through social media. when you see something happening in 1's state it will anchor people and others. everybody can pitch into the debate online when you are watching the pictures as we're sitting here

watching various pictures develop on twitter, acts and other platforms. it raises emotions, and tensions and the pictures on the news coming in from gaza and things like that. they are very emotive. social media does promote more emotive material. when it comes to student protests of course they are pretty organic, they can spread quickly. we've been seeing this over the recent days. reports from gaza to date not good. in the last few minutes the white house has said it wants answers on these reports of mass graves in the grounds of two of the main hospitals. we can show you some of the detail on that very shortly. the speaker is promising a hard—line response to this. he said school should have their federal funding revoked if they cannot control their campuses. he's also calling on the president at columbia university where he is today, it used to be the

deputy governor of the bank of england is calling for him to go. this has big financial implications for these universities. it this has big financial implications for these universities.— this has big financial implications for these universities. it does. the thing that's — for these universities. it does. the thing that's been _ for these universities. it does. the thing that's been condemned - for these universities. it does. the thing that's been condemned by i thing that's been condemned by the white houses in anti—semitic incidents that have happened at some demonstrations. there is been very intense and heated debates on university campuses ever since the hamas attack on israel in october. it's been very tense between pro—palestinians and pro—israel groups. we're seeing this demonstrated now by the protests which are spilling over into clashes with the police. there will be questions about how police have handled this. and the way in which they can escalate quite quickly if you go in with a heavy—handed approach. universities themselves being held to account about the way in which they decide to calm tensions. it's notable that the university of southern california decided to cancel graduation speeches because of back. emma,

thank ou speeches because of back. emma, thank you for— speeches because of back. emma, thank you for that. _ speeches because of back. emma, thank you for that. we _ speeches because of back. emma, thank you for that. we will - speeches because of back. emma, thank you for that. we will take i speeches because of back. emma, thank you for that. we will take a l thank you for that. we will take a short break. we see speakerjohnson we will go live to that. do you stay with us. we will be right back. hello. it has been another rather cold—feeling day for many parts of the uk. any sign of the temperatures lifting over the next few days? well, certainly notjust yet — staying chilly through thursday and friday. there will be some sunshine, but also some showers — some of those showers wintry over high ground in the north of the uk. a cold air mass enveloping the country right now, that cold air being drawn down from the north. also coming down from the north overnight, some areas of cloud, some bits and pieces of showery rain — i say rain, cold enough for some of the showers over high ground in scotland to be falling as snow. some snow mixing in above, say, 2—300 metres' elevation. it'll be cold enough for a frost as well, temperatures dropping perilously close to freezing, below freezing in some locations. so for thursday morning,

quite a cold start. areas of cloud bringing some showery rain across parts of england and wales, brightening up through the day across northern england. northern ireland and scotland, 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 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.
