Going to start in the us. Protests over the war in gaza have come to a head, with angry and sometimes violent scenes at campuses on both the east and west coasts. Take a look at these pictures. These are clashes at the university of california, los angeles campus. This was the early hours of wednesday morning, just a a few moments ago. A pro palestinian encampment has grown in size in recent days, as has the group of pro israeli protesters. There have been clashes between the two sides. These pictures are not live but we have been watching these pictures over the last couple of hours as they have been fed into us here at the bbc. Violence escalated around 11pm here at the bbc. Violence escalated around pm local time. It is now a around pm local time. It is now a a few hours after that. These are some of the most recent pictures we have. Dylan winward is a Student Journalist at the daily bruin, uclas student newspaper. He told me more about what has happened on campus. From 10. 50 this evening, Counter Protesters turned up as they have been doing for the last couple of days to disrupt the encampment. We know as well they fired off fireworks towards the encampment and there has been tear gas used on site. One of our reporters got tear gassed this evening as well. So that is what is currently going on there. We know that campus has requested a Police Presence from across the city to come in and from the latest ive just heard, they arrived several hours later.

Yes, the encampment is organised by Students Forjustice in organised by Students Forjustice in palestine, they have been there since thursday morning. They have a number of demands that the chief among them is to have the university divest from companies associated with the Israeli Military. They have largely been protesting peacefully. They have held programming, speeches and chanting. From the first evening they were there, overnight they were harassed by increasingly large groups of Counter Protesters. We are aware it is over 100 this evening. Some of whom have just been keeping them awake, shouting, playing music and in recent evenings, its also become increasingly violent. That brin. S become increasingly violent. That brinus us become increasingly violent. That brings us uo become increasingly violent. That brings us no to become increasingly violent. That brings us up to about ten, 11 oclock this evening. Clearly its very, very recent but what do we understand about what has happened, what changed in the mood and the atmosphere there . Yes.

In response, ucla leaders declared the income and Unlawful Assembly and students participating could face sanctions at the university. They stop short of saying they would arrest students on campus but they asked students to leave the encampment. This evening, at about ten or 11 oclock, we then saw a large number of Counter Protesters turn up, as they have donein protesters turn up, as they have done in recent evenings. We know yesterday evening there was also an altercation but it was nothing like we have seen on the scale tonight. They tried to breach the incumbent perimeter, as they have been doing for the last couple of evenings. Thus far they had been repelled. They were throwing objects, fireworks, they threw a scooter, Water Bottles and tear gas towards the encampment. That brings us up to what we have been seeing, these night time pictures from about 1am for about half an hour. There were periods where there were direct confrontations and then there would be a pause as people would step back. Talk us through the geography, this line of tents. Is this effectively the edge of the pro palestinian camp where they have been for a while and that is the focus point of the counter demonstrators, is that right . Yeah, what you are probably looking at is the central quad of the ucla campus. On one half of it, really, if the pro palestine encampment. There was a Barrier Set Up in between, with a buffer zone. There are 30 hired professional Security Guards hired by the university to separate protesters from Counter Protesters. We know this evening is the first time they actually withdrew away from the encampment site. We believe that is because they didnt feel they could safely hold it, allowing the two sides to clash directly. But previously, there had been a buffer zone. Those barriers have since been knocked over by the Counter Protesters this evening. Thanks to dylan for bringing us up to date with what is happening on the west coast. Meanwhile, on the other coast, hundreds of new york officers have entered the campus of Columbia University, ending the occupation of a building there. A long line of officers was seen climbing a ladder to enter hamilton hall. Lots of arrests, apparently. The university had told the students to leave or face being expelled. Columbia University Said the students had escalated the protest to an untenable situation and it had no choice but to call in the police. 0ur North America correspondent nomia iqbal has this report. As evening struck, so did the police. Targeting several campuses across new york. Nypd, go to hell at the city college, riot police lined up in front of angry crowds. The People United will never be defeated social media footage showed a huge confrontation with officers inside the encampment. About half an hour away, at Columbia University, where the protests originally started, police entered the campus. Shouting it comes nearly two weeks since they last went in, sparking huge controversy, and a day after some demonstrators broke into a building inside campus, smashing windows and barricading themselves in. For the university, it was a red line. Dozens have been arrested in this new police raid. Dozens and dozens of riot police are just behind this line here. We are at Columbia University, the actual entrance to the campus is just to my left, we cannot get anywhere near, it is about a two minute walk but the police have blocked it off entirely. Just earlier, we saw some students being arrested, they had their hands behind their backs with white zip ties being loaded onto nypd buses. Further down the right, you have more student protestors, more pro Palestinian Protesters on the other side of these barricades shouting shame, shame, shame at the police. The University Also set a deadline on monday to clear the encampment. Students who did not move are now being suspended. Protesters told us they were hopeful talks could still continue with the university. Their demands included cutting off economic and academic ties with israeli institutions. But given this latest police action, hope for reconciliation seems even further away. Nomia iqbal, bbc news, new york. We are going to head to the middle east now. The us Secretary Of State, antony blinken, says hes determined to secure a Ceasefire Deal in gaza and the only obstacle now is hamas. The group considered a Terror Organisation by the uk and us have until wednesday evening to response the the proposal. Mr blinken is in israel and has met president isaac herzog in tel aviv. Hes now due to meet the Prime Minister, benjamin netanyahu. Mr blinken also met some of the families of the hostages being held by hamas in gaza. He told demonstrators outside that the us will not rest until everybody is home. Ijust had an opportunity to meet with some of the families of some of the hostages, as i have on every visit to israel and, of course, as President Biden has done, so many colleagues have done. I just wanted to share with you what ijust shared with them. Bringing your loved ones home is at the heart of everything were trying to do. We will not rest until everyone man, woman, soldier, civilian, young, old is back home. There is a very strong proposal on the table right now. Hamas needs to say yes and needs to get this done. That is our determination and we will not rest, we will not stop until youre reunited with your loved ones. So, please, keep strong, keep the faith, we will be with you every single day until we get this done. In the past hour, a hamas official says Antony Blinkens comments are an attempt to apply pressure on the group. They say its still examining the terms of the ceasefire offer. 0ur middle east correspondent Yolande Knell has more on mr blinkens visit to israel. Certainly, were seeing some familiar themes coming up again on this trip. There is this deal that is currently on the table and you feel he is very much trying to keep up the pressure, putting the onus on hamas to accept what he says is an extraordinarily generous offer being made by israel. It would see, we understand, a a0 day ceasefire in gaza in return for more than 30 israeli hostages in the initial stages. Those more vulnerable hostages being brought back home, in exchange for Palestinian Prisoners being released from israeli jails. You can sense the frustration of some of the israeli hostages families. They were demonstrating outside the building where the us Secretary Of State was meeting the israeli president earlier. They really want america to use all its influence here. There have been calls from some far right ministers who are part of the Israeli Coalition government, really to prioritise an Israeli Military operation in rafah, in southern gaza, over what they describe as a reckless deal and the israeli Prime Minister has been commenting in a way that could complicate the deliberations being made by hamas leaders. He said that israel would go into rafah with or without a deal. Of course, hamas has been pushing for a full ceasefire that would bring an end to this war. But mr netanyahu analysts say, does he not fully support the deal that is out there or is he trying to keep his Coalition Government together . Because you have these thinly veiled threats from some of his ministers that they could quit the government if there was a deal that prevented israel from going into rafah, which it has said it needs to do to get rid of remaining hamas battalions and achieve a full victory over hamas. Thanks to Yolande Knell for that. Around the world and across the uk, this is bbc news. This is bbc news.

There are several vans and residents have been queueing up, trying to get in and out of the area and passing on their names to police as the Investigation Continues behind me. Now, of course, this attack was a very serious one. A 14 year old boy was killed. Several others were injured. Two of them were Police Officers. We now understood the details of how seriously these met Police Officers were impacted as they were protecting the community here. In fact, we can listen to the met Police Commissioner sir mark rowley giving small details. People say officers run towards danger. What youve actually seen on some of the videos that are out around social media and on news sites such as your own, you actually see what that really looks like. Youve got officers running towards someone whos waving a sword. I went to the hospital yesterday to see the officers and their families. I saw the inspector whose hand is badly damaged. I saw him before the operation, he was in good spirits. I think that was partly the morphine, to be honest right, 0k. But hes got a lot of patching up to be done on his hand, really serious injuries there. And i was talking to the family and colleagues of the officer, the woman officer, whose really badly damaged arm, really seriously damaged. The surgeon spent many, many hours sort of basically putting her arm back together. It will be a long journey of recovery. 0ne Newspaper said of the female officer, it was actually close to her losing her hand, are you able to confirm that . Thats not a million miles away. Really Horrifically Serious injuries. Of course, when you learn of an attack like this, one question does come up. Could this have been prevented . Now, the police have said that they are making urgent checks and that from what they can gather so far, there is no evidence that there was prior contact between the police and the suspect but they are continuing those urgent checks. For now, they are trying to get a bigger picture, a clearer picture of exactly something maggie has
