Tonights Eurovision Song Contest final . And the most powerful solar storm in 21 years triggers spectacular celestial light shows in many parts of the world. Hello, im sarah campbell. Israel has called on residents in new parts of Eastern Rafah in the gaza strip to evacuate and head to what it describes as a humanitarian zone on the coast. The move comes as a un official warns that supplies are hitting the bottom of the barrel with no aid able to enter via gazas southern Border Crossings. This is the scene live at a location which has been labelled an expanded humanitarian area by the Israel Defence forces. In a separate Evacuation Order on monday, thousands were told to leave rafah, ahead of what israel called a limited operation. Theres been fighting in parts since. These developments have happened as a long awaited Us Government report has criticised israels use of american supplied weapons in the gaza war, saying its reasonable to assess they have been used in breach of International Humanitarian law in some instances. Ourjerusalem Correspondent Yolande Knell has more detail on whats going on in rafah. Ok, so these new Evacuation Orders are still in the eastern part of rafah, but they suggest the Israeli Military is expanding its offensive there. Weve already been hearing that theres been Artillery Shelling in the centre of the city as well as in the east, israeli air strikes as well, and also israeli gunships off the coast have been opening fire, one of the residents there was telling us. But already israeli tanks have encircled an area to the east of rafah which they had told residents to evacuate from earlier in the week, so now those tanks do seem to be advancing. We have been told in recent days by the Israeli Military that this is still a limited offensive that theyre carrying out in rafah against hamas which they see as a hamas stronghold, this southernmost city, and they say they have killed a number of what they call terrorists. Theyve found terror tunnels, they say, in this area. And this does fall short, indications are at the moment, from the full scale Ground Invasion of rafah that the us and other world powers have really been warning israel against, but already we are seeing this crisis developing in humanitarian operations with, you know, the severe shortages of food and clean water and fuel which has a big effect on the hospitals, because we have had no aid coming in certainly since tuesday when the rafah Border Crossing was captured by israeli forces. The Kerem Shalom Crossing down in the south eastern corner of the gaza strip, well, israel says thats reopened, but because of the fighting thats going on nearby, the Security Situation means that no supplies can get into gaza that way either. And yolande, these people, thousands of people on the move and there are concerns that where theyre being asked to go to, muwasi, that there arent the facilities there to deal with such a large influx of people, so concerns there as well. The Israeli Military calls this a humanitarian zone but it is really not recognised internationally as being such. The Israeli Military says it has been expanded in recent days but those arriving in this coastal area in this sort of Tent City Have told us there are shortages of everything, they are not finding any supplies there, theyve got nothing to feed their children and that situation is not going to improve as long as these Border Crossings remain closed. Can ijust ask one more thing about this, this is all happening obviously as this Us Government report was published saying its reasonable to assess that arms have been used in ways inconsistent with israels obligations under humanitarian law, has there been any reaction from israel to this . Weve not had an official reaction from israel at this point, but israel has been saying consistently that it keeps to International Law, that it investigates any alleged abuses of International Law and that the force that its using in gaza is proportionate to the threat that it sees from hamas, in effect an existential threat. That was our middle east correspondent. Russian forces have launched a surprise new Ground Offensive in ukraine, crossing the border into the North EasternKharkiv Region. For months, fighting has been focused in the east, where russia occupies large areas. Fridays attack may be an attempt to open a new front and intensify pressure on kharkiv, which is the countrys second largest city. Small groups of Russian Troops with armoured vehicles pushed through the front line military sources say they advanced a kilometre before being pushed back amid reports of sustained russian shelling. These are pictures of volunteers helping people in settlements around kharkiv evacuate, getting out before the fighting gets worse. Our defence correspondent Jonathan Beale sent this report from kharkiv in North Eastern ukraine. Well, theres no doubt these are dangerous and difficult times for ukraine. Remember, since the start of this year, russia has taken about 300 square miles of ukrainian territory. The focus of its efforts have been in the east, where its been making slow but significant progress. But at the same time, russia has been massing forces, Tens Of Thousands of troops just across the borderfrom here, about 20 miles from the city of kharkiv, where im speaking to you now from. And in the early hours of this morning, some of those troops crossed the border, followed by what were told from ukraine, massive air and artillery strikes, and that they now have a foothold in the Kharkiv Region. President zelensky says they have repelled those initial attacks. But there are concerns there will be another wave in the coming days. But theres no doubt President Putin believes he has a window of opportunity here, notjust because ukraine is outgunned and outmanned, but also because of that delay in us military support, a delay of six months and that aid is only slowly coming to the front line. So these, as i say, are going to be difficult, dangerous months for ukraine. And already theyre being stretched right across this 800 mile front. Our correspondent in kyiv, james waterhouse, gave us this update. It creates for ukraine an unwanted new North Eastern access to the front line and this is a front line at the moment which is more than ioookm long and it is a front line which Ukrainian Forces are struggling to contain, with the delays of the arrival of american ammunition and weaponry and with russia continuing to make its size count and taking ukrainian territory further south. Crucially for kyiv, it is having to redeploy already stretched personnel to the Kharkiv Region to contain this incursion which we are told is being contained for now. There has been heavy fighting really for the past 2a hours and i think while few think they are able, even with the gathering of Tens Of Thousands of Russian Troops across the border, few think they are able to take cities like kharkiv because they failed the first time around. But it appears for now to be russia trying to form a buffer zone, try to extend the distance between russian territory and the fighting it is waging in ukraine, because Ukrainian Forces have been increasingly shelling targets inside russia. So the question really, as president zelensky admits, is what is going to happen next, we are containing it for now but is this russia building for something more . More than 150 people in afghanistan have died in flash floods in the Northern Province of baghlan, according to the taliban. Thousands of houses were destroyed or damaged when heavy rains on friday sparked massive flooding. Brazils Sports Minister has asked the Football Confederation to temporarily suspend all National Football competitions because of the floods that have devastated the state of rio grande do sul. At least 126 people have died and more than 400,000 have been forced to leave their homes. Prince harry and meghan are in nigeria this weekend as part of the dukes promotion of the invictus games. On friday, they launched their tour in the capital, abuja, with a visit to the Lightway Academy college, which receives support from their foundation to educate young girls affected by conflict. Later today they will meet Wounded Soldiers who are representing the country at next years event in canada. 0ur africa Correspondent Simijolaoso has more. They have been getting a really warm welcome here in abuja. Prince harry went to the ministry of Defence Headquarters where he received a Military Salute and they are the department behind their visit. And as you mentioned, they went to a school here in abuja where they were greeted by a group of really excited and enthusiastic schoolchildren there. They spoke about Mental Health and prince harry told the students to promise to be open about their Mental Health and not to lock in their emotions and also to kind of kick the stigma around Mental Health into the long grass, he said. He also told them that he wants them to remember that its ok to not be ok. After their visit, i spoke to a couple of the students. One girl told me that she was left really inspired by their message, especially having such a high calibre couple come to visit their school and that she herself had suffered or struggled with anxiety and depression. And now she feels the courage to be able to speak out about her Mental Health. The most powerful solar storm in more than two decades has been hitting the earth, triggering spectacular celestial light shows in many parts of the world and bringing possible disruptions to satellites and power grids. Such storms occur when the sun emits large clouds of particles, known as Coronal Mass Ejections with scientists expecting this one to persist into the weekend. Its meant many people across britain have been able to see the Northern Lights, a phenomenon which isnt normally visible to people in southern england. This was the scene in the skies over 0xford. But these scenes in switzerland may have trumped the skies over the uk. These are pictures of the Northern Lights over swiss alps. Absolutely glorious. Helena wilkinson reports. A Tantalising Glimpse of the spectacular light show that was about to unfold across the uk. At crosby beach in liverpool, people gathered to witness the breathtaking sight, a burst of Colour Lighting up the clear overnight sky. The Northern Lights made a rare appearance across the uk. This was manchester, the city bathed in a bright, colourful glow. Clear conditions meant parts of the country were treated to dramatic displays. This was the dazzling scene in hornsey in yorkshire. Liam james, who captured the moment, described it as the best display hed ever seen. Even more southerly areas like basingstoke in hampshire were treated to the spectacle. The Northern Lights are caused by the earths atmosphere reacting to Charged Particles from the sun. This is sort of a huge explosion that can be associated with the flare. But basically what happens is part of the sun actually lifts off the surface. So this plasma, the Charged Particles, the Magnetic Field that makes up the sun, part of it actually lifts off the sun and streams away into space. If you missed last nights display, there might be a chance to capture it this evening. Helena wilkinson, bbc news. Which is great news for all of us who missed it all because they were asleep we will try again tonight. Now its time for a look at todays sport. It could be a weekend in the English Premier League title race too. The leaders arsenal dont play at Manchester United until sunday, so manchester city, currently one point behind, have the chance to go top of the table in the next few hours. Fulham are their opponents. If city win their final three games they will be champions for the fourth time in a row. Manager pep guardiolas trying to take it all in his stride. These guys we still rely on them and we can do it, and here we are. A week left to finish the Premier League and give all we have in our bones to perform, a sunny day in london. Last season it was so dry, so we have to fly back with three points. In the fight to avoid relegation from the Premier League, Nottingham Forest know victory for them over chelsea will see them all but safe. As for rob edwards and luton town, they need forest to slip up and to get something themselves at west ham. We will concentrate on ourselves and obviously we will need help, but we all know how difficult it is to win in the Premier League and we have got to try and do that and see forest, burnley, got difficult games as well, but they are all tough, but without as doing ourjob it doesnt matter what anyone else does. For burnley and manager vincent kompany, the maths is simple they have to win their final two games if theyre to have any chance of staying in the Premier League, starting at tottenham later. We will have plenty of time to talk about what the season has been for us, good or bad, but right now i dont think we have to play out any scenarios. The only thing i know is we will keep going, that i guarantee you, no matter what. You just keep going and rewards dont get distributed in life because youve done something exceptional in that one given season, it is because you have prepared yourself for a long time to have that one moment. This could be the day celtic effectively win the title in the scottish premiership. If they win the Old Firm Derby which kicks off in little over an hour, theyll go six points clear at the top with two games remaining and a better goal difference. But victory for rangers would bring them level with the leaders. It is about being there as a player, it is about taking the moment, it is about being there is a group of players and grabbing the moments and you know there are always at small margins that decide this kind of game and you need to take all these things as much as possible. There is much more build up to the weekend pass football over on the bbc sport website. But for now, that is all your sport. Talking about build up. The Eurovision Song Contest reaches its grand final on saturday night, with croatia, israel and switzerland among the favourites to win. Crowds are gearing up in the swedish host city malmo. Maryam moshiri is there. I remember watching you last year and on the day of the final, the atmosphere was glorious, joyous, happy, is there any sense this year that things feel slightly different . It will always be different, liverpool was amazing, the best week ever. It is amazing here as well, the Eurovision Bubble is still around, but there is a different feeling this year. The city of malmo has hosted eurovision three times, sweden has hosted seven times, this is the seventh time, but this is one of the most controversial contests we have ever seen, take a quick trip behind me if you can. Look at the crowds, they are snaking, meandering, whatever word you want to use come across this square into the arena behind me. The final rehearsals are going to take place imminently of the final 26 acts, but will there be 26 acts, we dont know. We are still waiting for the organisers to tell us whether the dutch act, joost klein, will be singing into nights final. Well know what happened yesterday, there was huge amount of confusion just before the second rehearsal when he was taken off air and was not allowed to rehearse with the other contestants. The latest line we are hearing today is that the dutch press are saying Swedish Police are investigating an incident which occurred involving joost klein just moments before the dutch act was supposed to go on air.
