Violent clashes between israeli troops and palestinians have spread across much of the occupied west bank, following days of hostility in gaza. The israeli Prime Minister Benjamin Netanyahu has warned that israels biggest offensive against hamas in gaza in years is not over yet. Its estimated ten thousand palestinians have had to leave their homes to flee the israeli bombardment. Rockets were fired by militants towards israel from the territory for a fifth day. At least 122 people in gaza have been killed, and 9 have died in israel since fighting began on monday. From jerusalem heres our middle east editor, jeremy bowen. The sectarian crisis nobody expected is deepening. Tonight arab protesters are on the streets of northern israel. This was nazareth. They are forced back into the wider conflict that includes gaza and jerusalem. It is ugly and angry in a town shared byjews and arabs. Violence between citizens could be a bigger crisis for israel than gaza. This was a burnt out jewish school. Police broke down the door of this family. They deny accusations their sons were attacking jews. The police say their offices behaved correctly. The father, the imam of a mosque and his two sons were arrested for attacking police officers. The woman who filmed this said they are scared, not ofjews, but of racist police. A local rabbi visited, she said, to apologise. In gaza, they buried this 13 year old. He was hit during an israeli air strike while he waited for a new haircut to celebrate the end of ramadan. Half of girls of� s 2 million palestinians are children. This is the boys brother. In the occupied territories and in israel, events this week have exposed once again, the mutual hatred and fear that are the essence of this conflict. This was hebron during a day of protest on the occupied west bank. More palestinians were killed. Injerusalem, palestinians pelted jewish settlers with stones and fireworks. The settlers hit back with live bullets. This was sheikjarrah, were attempts to evict palestinians from their homes helped the escalation to war. The conflict crosses borders. Injordan, the country next door, Security Forces kept protesters back from the frontier. Palestinians make up more than half of thejordanian population, mostly refugees from past wars not permitted to return by israel. History never dies in this conflict. People do. Earlierjeremy shared his take on the situation and whether an escalation was likely. The israeli operation overnight in gaza was certainly an escalation. There are question marks about what capacity hamas has left to send missiles into israel. No one really knows what their stockpile is, and they have used a lot, the way that they bypass when they can, is really antimissile systems is by sending a whole lot all at once. So, yeah, if ever there was a moment for diplomacy, and they are attempting to start the process up, then its now. Because from here the only way is down without it. In a sense, the issues have been building up for a lot of years. Israelis who are, israelis who are arabs, who have israeli documentation but a palestinian origin have always felt like second class citizens. And as a result of that theres a lot of anger, and at the same time theres the right wing, far right extreme nationalism in Thejewish Community and this is something that has been pushed more into The Public Eye and into the mainstream. And maybe even a little bit more respectable for some people because of the way the Prime Minister, mr netanyahu has been more than flirting with them for their support. Our middle east editor, jeremy bowen injerusalem. The us envoy hady amr has arrived in israel for talks. The state Department Deputy assistant secretary for israeli and Palestinian Affairs touched down at Ben Gurion Airport earlier. The Biden Administration on friday reiterated that it was working toward De Escalation of the Israeli Palestinian conflict and a lasting peace in gaza. For more on the Biden Administrations response to this latest violence ive been speaking to martin indyk, a former us special envoy for middle east peace. I do think that they were surprised at the way things got out of hand injerusalem. But then, everybody was. The events there took basically everybody by surprise i dont think its commonly known that thejoe Biden Administration did weigh in with Prime Minister netanyahu and the march into the old city, stop the evictions and essentially got the police to back off. But it was too little too late. And now, i think with them on the ground there, theyre in the position to get in with the egyptians flown in, to see whether or not it is possible now to get a cease fire in place. I have the sense that hamas may be ready for that and i dont see that the israelis have objectives that they can achieve beyond what theyve already done that make a lot of sense. To go in on the ground, gaza is a very complicated thing for Prime Minister netanyahu and it can only lead to more casualties on the palestinian side more criticism of israel, military casualties, and he is looking at a fifth election and so i dont think he is going to want to go into an election with that situation. Im seeing both sides of this essentially trying to achieve their limited objectives and now, it is possible, possible to get them to back down and agreed to the cease fire. And we are talking about the usual scenario that we have with this, that this will be managed in the escalated, but the ultimate resolution of this is not achievable . Yes, that is the tragedy of the Israeli Palestinian conflict. Its not as if there have been many efforts under the last 35 years to try to resolve the conflict. Ive been involved in some of those efforts myself. But theyve all come up short in terms of ending the conflict. What has worked in the past and the reason why you have palestinian control that is not only controlling 90 of the palestinians in the west bank, but the palestinian authority, is because of an incremental approach and may not be possible to get back to that kind of incremental approach. Where you dont raise expectations that the conflict is going to be ended because i think that is now a bridge way too far. The head of the World Health Organisation has urged rich countries to reconsider plans to vaccinate children and instead donate jabs to the covax scheme for poorer countries. Tedros also warned that the second year of the coronavirus pandemic is set to be far deadlier than the first. I understand why some countries want to vaccinate their children and adolescents. But right now, i urge them to reconsider and instead donate vaccines to covax. Because in low and lower middle Income Countries vaccine supply has not been enough to even immunise health and care workers. For more on the reasons behind the who warning heres professor martin mckee from the London School of hygiene tropical medicine. If you look at whats been happening in india, you see why he is saying it and the same thing happening in nepal and neighbouring countries in asia. Theres still a lot of potential for spread in africa that we have not seen yet. But theres a real risk there. As long as this virus continues to circulate, it will continue to mutate and that is the real worry. Until we can get levels down everywhere, that means getting everyone vaccinated and as dr tedros said, such as the vaccination, its a combination of the vaccination in the Public Health measures. Then we can be more optimistic, but were still far away from that. And the concept that the coronavirus is somewhere, it is everywhere. Your priority in that case of the International Community is to do what . Priority is to get as many people vaccinated as possible while keeping it under control with the continuation of Public Health measures which we can do now and everywhere, of course. When it comes to the countries that, the uk included, theyre doing well there and getting people vaccinated, what should they be doing with their doses and vaccines . Should they be giving them to covax and should they be giving to those communities who perhaps do not have as much . With the new variants that are circulating, we have an r number of about over three anyway. That means the proportion of the population that have to be immunised to suppress transmission need to be very high. Perhaps 85 . In western countries at the minute, we are not largely vaccinating children who make up about 20 of the population, so were not going to get to that. That is one thing just to bear in mind. The real issue is that we just need an awful lot more vaccine and there are all sorts of issue around that. Paying for it, but production among other things. There are issues around intellectual property, not just the vaccines themselves, but the capacity. We need to think very carefully and clearly about how we can strengthen Health Systems to make sure the vaccines can be distributed. I think if we look at what happened with hiv many years ago, there was a focus on making sure the drugs were affordable. So they could actually be obtained in the country that we overlooked the need for the strengthening of the Health Systems to make sure that people could get them. So, there are a lot of things that we need to take account of here. We also need to take account of some countries reports today like from Papua New Guinea for example, where the Prime Minister got vaccinated but even there, it was clearly a lot of vaccine hesitancy. Things like that need to be overcome and so no single measure, no single magic bullet, we need to do a lot of things altogether. The school of hygiene and medicine with his perspective, here in the uk, the Prime Minister borisjohnson has said that the new indian variant of coronavirus could pose a serious disruption to the progress made in tackling the virus. Cases of the indian variant have more than doubled in a week, with more than 13 hundred cases, mostly in england. Heres our medical editor fergus walsh. Long queues for immunisation in bolton, which now has the highest level of coronavirus in the uk. It is one of several areas where the indian variant has now got a foothold, encouraging people to get the jab. Personally the reason for me getting the vaccine is because i live with elderly people and i dont want them to have have worries. It is thought vaccines will continue to protect against serious illness, but the threat from the indian variant has led to a shift in policy. The gap between first and second doses for the over 50s is being cut from 12 to eight weeks in a bid to boost their immunity. The Prime Minister warned the final lifting of restrictions in england onjune 2ist was now in doubt. I have to level with you that this new variant could pose a serious disruption to our progress and could make it more difficult to move to step four injune. And i must stress that we will do whatever it takes to keep the public safe. The indian variant, bi. 6i7. 2, was first identified here less than a month ago, linked to travel from india before it was put on the red list for hotel quarantine. Cases have more than doubled in a week to over 1,300, but that will inevitably be out of date because it takes time to sequence samples. It now accounts for around 10 of coronavirus cases in the uk. But we are in a far better place than we were just a few months ago. Back in the Peak Injanuary there were one and a quarter Million People infected with coronavirus in the uk, that is one in 50 people. The latest survey from the office for National Statistics suggests that is down to around 47,000, or one in 1,400 people. Get used to this, you are likely to see more of it. Queues for Pcr Surge Testing here in formby, merseyside, one of 15 areas in england where the new indian variant has established itself and maybe displacing the kent variant, the bii7. This is more transmissible and we expect over time this variant to overtake and come to dominate in the uk in the way that the kent variant took over and other variants took over prior to that. The Scientific Advisory group, sage, says the indian variant could be as much as 50 more transmissible. If it is, they warn that could lead to a substantial resurgence in hospitalisation. But for now the number of Covid Patients continues to fall, at its lowest level for eight months. The big question, what will happen in the next few weeks . Fergus walsh, bbc news.

As israeli strikes against targets in Gaza Continue Prime Minister Benjamin Netanyahu warns the offensive against hamas is not over yet. The World Health Organization has warned that the second year of covid is on track to be far deadlier than the first. The United Nations is warning of a sharp rise in the number of people dying as they try to reach europe by sea. With warm weather and falling covid rates, more migrants are attempting the journey. Our europe correspondent nick beake and video journalist Bruno Bull Paahp have this exclusive report on a dramatic rescue. Stranded in the middle of the atlantic, a helpless migrant boat. The spanish Military Helicopters overhead have never spotted anything like this here. Its 300 miles from shore. They realise there are many bodies. Translation this was a mass grave in the middle of the water, or really in the middle of nowhere. I believe their hopes had vanished into the ocean. But incredibly, there are survivors. Including a 17 Year Old Girl called aisha, here in the red jacket. Its now a race to save them. Its the end of april and theyve been drifting for three weeks. Translation there were men who could no longer stand up i and who screamed from thirst. Please, i need to drink water. Can someone please give me water. We used a shoe to give them some sea water. Aisha, a teenagerfrom ivory coast, thought europe would offer a brighter future. She saw 56 people die in front of her. Translation after two days we had no more water left, no food. On the fourth day, no more petrol. At the beginning when somebody died, wed say a prayer. By the end, there was no prayer. We didnt have the strength to throw any more bodies in the water. With summer on the horizon, thousands of mostly young men from north and west africa are trying to get to europe. Some are fleeing war, others, the economic hand that life has dealt them. Populist parties say tougher action is needed to stop this. Its a crisis that was masked momentarily by covid, but never solved. Aisha has been welcomed with open arms in tenerife and now, a reunion this man, who lifted her from the boat. Hes brought his family to meet her. For so many others on her boat, there was no new beginning, it was the end. Aisha was one of only three survivors. This was the greatest loss of life in any single known attempt to reach the canary islands. The 2a bodies that were recovered will now be related to rest here. For the others lost at sea, there is no such dignity in death. Aisha never thought shed be able to speak to her family again, but made a good recovery during her ten days in hospital. She hopes to stay in europe, study and work here and send money back to her parents. This man and his team head off on their next training mission, knowing full well that even the might of the Atlantic Ocean is not enough to stop those prepared to risk death if there is the slightest chance of a better life. Nick beake, bbc news, in the canary islands. A Second Laboratory in brazil has announced it will be forced to stop Coronavirus Vaccine production because of a lack of ingredients. The Butantan Institute in sao paulo said supplies were being held up in china waiting for export clearance. On thursday, a laboratory in rio dejaneiro, said it would restrict astrazeneca Vaccine Production to certain days until new supplies arrived. Congressional republicans have voted in an ardent trump supporter, elyse stefanik, to replace liz cheney as their third Ranking Party leader. Stefanik from new york has consistently backed the false claim that the 2020 election was stolen. Now, americas world famous museums are starting to open up as covid cases decline. Next week, the new york Art Galleries can open at 100 capacity. In washington dc today, the National Museum of African American history and the National Portrait gallery opened their doors for the first time in over a year. The bbc� s larry madowo was on the scene. Americas capital has felt a little deserted this past year. Its time to spruce up, though, as the city slowly rolls back to normal life. Check out a monument, or go all in and visit a museum again. The National Museum of African American history and culture even got a guest from the white house. We are opening up. Culture and beauty coming back to dc. First lady drjill biden. Hi, how are you all . Good, how are you . Im doing well. So you have two tickets . Yes. The National Portrait gallery has also reopened to some early demand. Tickets are free, but they are fully booked for the next two weeks. The green spaces are great, and especially since they are a little bit more empty right now its nice to be able to see everything more clear. But i think museums are pretty much the sole of most your most touristy cities like this. One of the new additions is a temporary display of former president trump. The official post president ial portrait has not been commissioned, but the gallery is in talks with trump and his team. Even though this one is temporary, lets see how they portray him after such a controversial president. Museums are happy to have guests wandering the halls again after the pandemic forced most programming to shift online. It brought in new audiences, especially internationally. But theres nothing like actually being here. We are a museum about people, by people, for people. So obviously we are missing the people and we are excited for them to come back to complete the portrait gallery experience. There are still capacity limits, but this is another step forward as america balances the urgency to reopen the nation with some hesitation to give everyone healthy. The museum had to shut down again after its initial reopening last year because covid cases increased. This time more americans are vaccinated and cases are down, so the doors might stay open. Larry madowo, bbc news, washington. Iamso i am so jealous that larry gets to go to a museum. Incredibly gerritjealous. Dont forget you can get in touch with me and some of the team on twitter im bbckasiamadera. Hello there. If youre waiting for a prolonged, dry, warm spell of weather you have to keep on waiting because this weekend it is going to stay cool and there will be plenty more heavy, thundery downpours. On the atlantic Satellite Picture you can see this big pipeline of cloud just ploughing its way from west to east. You can think of this line of cloud as something of a barrier. Its keeping the warm air away from our shores. That air will lift temperatures across parts of Southern Spain this weekend into the low to mid 30s. For us, we are stuck in cool air and we are stuck under the influence of low pressure. This will bring showers or longer spells of rain through the weekend. A band of cloud with outbreaks of Rain Drifting Northeastward across england and wales, clipping into Northern Ireland as we head through saturday morning. Behind that we revert to that mix of sunshine and showers. Some of the showers will be heavy with hail and thunder. Not too many showers across scotland. Certainly across the northern half of scotland as we go to the day. Although for shetland it will stay pretty grey and damp all day long. Temperatures struggling for northeastern areas just 11 degrees. Even in the best of the sunshine 15 or 16. That is it. Through saturday evening the showers will try to fade but actually i think through the early hours of sunday morning, the showers will pop up again down towards the southwest. That is the first sign of what is going to be quite a turbulent day of weather on sunday. As this area of low pressure moves right on top of the uk. That means the air will be very, very unstable. So while most places will start with some dry weather and some sunshine keep an eye on the skies, you will see big thunder clouds developing. Some really intense downpours and frequent lightning, some hail, some very squally, gusty wind and some particularly strong winds towards the channel islands. There will be some sunshine between the showers but temperatures low to ii to 15 degrees. As we head to the start of next week low pressure will still be close by. That means we will see further showers or longer spells of rain through the week ahead. Some of the showers always with the potential to be heavy, possibly thundery. Some sunshine in between but no sign of anything warm on the horizon. This is bbc news, the headlines. Violent clashes between israeli troops and palestinians have spread across much of the occupied west bank. Israels Prime Minister has warned that israels biggest offensive against hamas in gaza in years is not over yet.
