was known to authorities in france for trying to stage another attack in 2016. french anti—terror prosecutors say they will be taking over the investigation. in the past hour, the french president emmanuel macron has issued condolences to the family members of the german man killed in the attack. fierce fighting has resumed in gaza after the collapse of a temporary ceasefire between israel and hamas. israel has ramped up airstrikes on gaza, telling residents to evacuate to other areas, but aid groups say nowhere is safe. prime minister benjamin netanyahu warned the war is far from over. translation: we will. continue the war until we achieve all its goals which is impossible without the ground operation. it was necessary to bring the results until now and it is necessary to bring the results moving forward. israel's been carrying out intense air strikes on khan younis in southern gaza. israel says hamas leaders are in the city, but it's also where hundreds of thousands of palestinians have been sheltering after being told to flee from the north. residents are describing it as some of the heaviest bombing of the war yet. people in the eastern areas of the city have been told to evacuate further south. khan younis was one of the places they were told to flee to in the earlier stages of the war. our middle east correspondent lucy williamson has this report. khan yunis, gaza's southern capital, once labelled safe. america says this new phase of israel's war in gaza must look different to before. two days in, it looks and sounds the same. residents say the bombing of khan younis is the heaviest since the conflict began. this city where senior hamas leaders are said to be hiding. israel has told people to move to shelters further south. nader abu warda and his three children fled here from the fighting in the north. translation: the israelis told us that khan yunis was a safe zone, which led us to flee here. now, even khan yunis has become a war zone. where are we supposed to go? our children are stranded on the streets. israel says military pressure on hamas helps free hostages. 110 women and children were released before the truce broke down. really, today was my worst day. yarden gonen's sister romi is still there. the negotiation and the releases and everything gave me hope that i will win the lottery the next time. i just know that my sister is waiting and she saw the other ones get released and she knew that she could be the next one. tonight, families and their supporters held a rally in central tel aviv. the strain of the last two days colouring the mood. the star speaker, yelena. released by hamas but forced to leave her son behind. translation: i'm happy and excited | to stand here in front of you. i came to say thank you because without you, i wouldn't be here. and now we have to go back and get my sasha. the stories of hostages and their families are starting to diverge. after a week in which more than 100 women and children were released, there is now an effort to keep up pressure on the government not to leave anyone behind. negotiations to release more hostages seem to have stalled. some here worried that military goals are now the priority. israel has said bombing and bargaining can take place together, something forfamilies to cling to. lucy williamson, bbc news, tel aviv. hospitals there are operating with limited resources after weeks of fighting. uncief spokesmanjames elder is in khan younis and says hospitals are overwhelmed with casualities. densely populated. 1.8 million people are now in this area. sorry... another explosion. i am not far from the sea. so i have no military expertise but i am understanding that would be artillery from the navy and the ones that shake the window or even glass breaking with these things and shattering and does horrible things to a child's body so there is a base and you go on convoys to the north or delivering aid here or wherever we can possibly get aid to. i know the north is unreachable at the moment. people are utteraly terrified. you could ask a question in english from a lot of people which is will you end the war, are you here to end the war? and by answer, my brain is, no, your life is being decided elsewhere. we are simply here to stem the bleeding. the us secretary of defense lloyd austin has weighed in, warning israel that it should be shielding civilians. you see, in this kind of a fight, the centre of gravity is the civilian population. and if you drive them into the arms of the enemy, you replace a tactical victory with a strategic defeat. so i have repeatedly made clear to israel's leaders that protecting palestinian civilians in gaza is both a moral responsibility and a strategic imperative. these are the live pictures of gaza right now, where it'sjust after 3am in the morning. we have seen are flashes of light lighting up the night sky. it appears the military operations there continue. the israeli air strikes in gaza south making it difficult for civilians to reject themselves. i discussed that with our diplomatic correspondent paul adams, who's in jerusalem. cani can i start with the leaflet is that we know israel has been air dropping over the gaza strip as it renewed its bombardment. do people receiving them understand where to go, where we save areas are? leaflets in general have caused confusion and uncertainty in the past. what we see at the moment is a slightly new iteration of this policy with this detailed map of the gaza strip broken down into numbered grid squares. the idea being now not that israel will direct people towards save areas that they will direct people away from under save areas. the maps that have been dropped have areas are shaded which show where the israeli military is planning to conduct its military operations and it is urging people to leave those areas. that is a different approach and one has to assume that from day to day, those unsafe areas will change as israel's military priorities shift and change. we are not overhyped for a few days this new strategy is working any better than the old one which was a rather blunt form of warning for people in whole areas just to move south or to get out of the way. this is more precise but we don't yet know whether it is more effective. another thing worth bearing in mind is even outside of the defined area, israel still reserves the right to conduct what it calls on high—value targets, and those can be as palestinians have found to their cost, anywhere and at any time.— and at any time. can i speak about the — and at any time. can i speak about the negotiations - and at any time. can i speak about the negotiations as i and at any time. can i speak. about the negotiations as well which of course had been under way in qatar, benjamin netanyahu now seen they are pulling their team from qatar. what does this mean for the potential of a further temporary truce and also of course the question when it comes to those hostages still remain inside gaza? fist comes to those hostages still remain inside gaza?- remain inside gaza? at the moment — remain inside gaza? at the moment it _ remain inside gaza? at the moment it means - remain inside gaza? at the moment it means there . remain inside gaza? at the| moment it means there are remain inside gaza? at the - moment it means there are no negotiations and therefore no prospect of any immediate resumption of the truce. israel has for the delegation out, benjamin netanyahu speaking on television tonight saying that only military force had secured the release of the 100 or so hostages who were released over the past week and that is what israel is about to do again in the gaza strip. hamas said there will be no further releases of any hostages until there was a complete ceasefire is at the moment using the two sides are very far apart on this. whether the various negotiators who have been involved in trying to get this ceasefire up and running cannibals off again, i don't think so, not in the short—term. it was at the moment as if israel is determined to pursue military pressure for the time being. with regards to continuing that military pressure, that was something that benjamin netanyahu touched on in the press conference that he was giving, essentially saying that aim to eradicate hamas it continues. i wonder weeks now into the conflict, do we have a clear idea as to what the idf has been able to achieve in pursuing that aid?- has been able to achieve in pursuing that aid? they said that even — pursuing that aid? they said that even before _ pursuing that aid? they said that even before the - pursuing that aid? they said i that even before the ceasefire a week or so ago they were making significant progress in the northern part of the gaza strip, they had defeated a number of the hamas are fighting battalions and they still have work they want to do there so we are seeing some intense street fighting in parts of the gaza city, that is likely to continue for some time until they feel we have the whole of the northern area under their control. then attention in terms of ground forces, attention will probably turn to the south. we already think probably simon grant operations in this output in terms of a major push into the south, that maybe still some time away and then israel will essentially be trying to achieve the same thing which is to go after the hamas infrastructure, the titles, the command centres, searching for the leaders and continuing the search also for hostages. all of that presents the prospect of that presents the prospect of a military conflict that has got weeks, probably months still to run, with some reporting suggesting that basically we will be seeing military action of one form or another throughout the coming year. another throughout the coming ear. ., ~' another throughout the coming ear. ., ~ , ., another throughout the coming ear. ., ~ ., another throughout the coming ear. ., ., year. thank you for your reporting- _ turning now to the un climate summit in dubai, where leaders have made more promises to combat climate change. while the day prior focused on food production's contribution to global warming, the focus of the most recent talks shifted to renewable energy. around 100 countries promised to triple world renewable energy use by 2030. additionally, 50 oil and gas companies, including saudi giant aramco, pledged to stop adding to planet—warming gases by 2050. that pledge, however, only covers emissions from production, not the burning of fossilfuels. critics say the promise would not meaningfully tackle climate change. but countries pledging to triple renewable energy at the cop28 summit said it would help remove fossilfuels from the world's energy system by 2050 at the latest. the bbc�*s climate editorjustin rowlatt has more from dubai. the pope couldn't make it to dubai — his doctor forbade him from travelling — but a cardinal read his words. climate change has "run amuck", he said, and he posed a question for the gathered leaders. are we working for a culture of life or a culture of death? to all of you, i make this heartfelt appeal. let us choose life. let us choose the future. some of the pope's demands are already being addressed by this summit. he said the world must move ahead with greater energy efficiency and more renewable energy. we got pledges on both of those today. and we had another new announcement from around 50 oil companies, including the world's largest, saudi arabia's aramco. they said they would drive down the carbon emissions from refining oil into petrol, diesel and other products to net zero by 2050. now, that would reduce the carbon produced by a litre of petrol by up to 15%. it's better than nothing, but really, we need to stop using this stuff completely. the pope and the secretary general of the un have both said fossil fuels need to go. the american and chinese climate envoys entered the meeting side by side — a sign of their closeness on the climate issue. gentlemen, will you commit to phasing out fossilfuels here in the uae? i think you're going to hear a good discussion in the next few days. so, no public commitments today. the us vice president said america understands the challenge. the urgency of this moment is clear. the clock is no longerjust ticking. it is banging. we need transformative change and exponential impact. and it sounds like the president of these talks has also got the memo. the world can break down if we don't rapidly transition to zero—carbon alternatives. these are facts we must come to terms with. so, does that mean the uae believes the world can finally agree to phase out the use of unabated fossil fuels? that's when you capture the c02 to stop it causing climate change. here's what the head of the un body that runs these talks had to say. we have to try and it's up to parties. that is un speak for only the countries of the world can make that call. but there are some tantalising hints here in dubai that we could be gearing up for a really consequential decision at cop28. justin rowlatt, bbc news, dubai. and as more climate commitments are made, i spoke to the thomson reuters foudnation's climate editor laurie goering about what impact they will have. today the focus has been all about renewable energy. we have seen some pledges from around 100 countries pledging to triple by 2030. i countries pledging to triple by 2030. i put countries pledging to triple by 2030. i put that into context for us. how meaningful could that be?

i think that is still possible? i think most scientists think we will pass the 1.5 degrees mark. what they are hoping is that when we pass that we will do it by little and will be able to pull back emissions using some new technologies and things that are out to try to get it back down below 1.5. whether we will be able to do that is not clear but there are really big risks to the world from passing 1.5. there are a lot of tipping points out there around things like the melting of the greenland ice sheet that could raise sea levels by seven metres around the world, and a range of other things. it is important we try to stick to that goal and if we pass it, which is now likely, because emissions are still rising, rather than falling, that we try to get it back as fast as possible. try to get it back as fast as possible-— try to get it back as fast as ossible. ~ . . , , possible. watching this summit unfold and _ possible. watching this summit unfold and reporting _ possible. watching this summit unfold and reporting on - possible. watching this summit unfold and reporting on it, - possible. watching this summit unfold and reporting on it, as. unfold and reporting on it, as you do every year, i wonder whether you think this summit has more momentum compared to previous summers? and if you agree with that, or not, why do you think that is? we have seen some incredibly dramatic weather related events this past year, thinking of the flooding in libya, the devastating wildfires in hawaii. do you think this world leading polluters are starting to get the memo?

i think that's true. i think everybody, not - true. i think everybody, not everybody, but lots of people around the world are seeing climate impacts for themselves. it is increasingly evident. it is increasingly expensive. and it is increasingly costing lies around the world. so i think that, yes, they have been some really good promises and pledges and things happening at this cop early on. not least the loss and damage fund to help these countries deal with problems that come up and they have done very little to cause, because they are low emitters. but the pledges important. pledges are pledges and they always met. i think there is good momentum but the real test will be whether there is an agreement to phase out fossil fuels, including oiland agreement to phase out fossil fuels, including oil and gas, notjust coal, and it should go beyond unabated, really, to have significant impact. i know ou will have significant impact. i know you will be _ have significant impact. i know you will be watching _ have significant impact. i know you will be watching for - have significant impact. i know you will be watching for that i you will be watching for that very closely. laurie goering at the thomson reuters foundation, agreed to have you with us. thank you. agreed to have you with us. thank yon-— agreed to have you with us. thank you. agreed to have you with us. thank ou. ., ., ., ,, thank you. --
