around the world, september 7th on d, w. ah, this is d w. news coming to you live from berlin. russia once again targets ukraine, 2nd largest city. rockets, rain down on cocky destroying the university building and bringing the death toll the days of attacks to at least 18. also on the progress german chancellor, all of shoulds take the witness, stand at a probe into the country's biggest ever tack scandal. but he says he can't remember crucial detail. and the mystery of the dying fish. thousands of them washed up on

river banks in poland and germany. now scientists may have an answer to why a river ran gently. ah hello, i'm terry martin. thanks for joining us. russian shelling continues to target hakim, ukraine's 2nd largest city. ukrainian officials say at least one person was killed when 5 rockets hit the city early on friday, between wednesday and thursday, 17 people died in russian shelling in hockey. meanwhile, media report say a russian air field in crimea has been rocked by a series of explosions. the blasts were reported near a military airport. north of the city of sebastopol, we're thought were dozens of combat aircraft, were parked. russian occupation authorities are quoted as saying,

no damage was done. this comes as united nations secretary general antonio terrace, is business ukraine. on thursday, he held talks in the be with the countries president followed him, his lensky, and the turkish lead. a rich of type our to juan gutierrez repeated his calls for a safe zone around the russian occupied apparition. nuclear power plant, nearly ferry equipment and but so now some new withdrawn from the plants. further, the deployment of forces on equipment, the sides must be avoided. the area needs to be the leap at eyes and we must feel as he sees any potential damage who's up? what easier is suicide. gutierrez is now in the ukranian port city of odessa. we're dw correspondent young phillips schultz has been covering his visit. i asked him what the un chief hope to achieve their a year in odessa, the secretary general's big goal is to follow up on the so called grain veal,

as you know, the united nations and turkey broke out a deal some weeks ago. that enables a resumption of vital grain exports from ukrainian hordes and odessa is the biggest part in ukraine really vital for the ukrainian economy. so a very symbolic, a very important place. and in some me to in some minutes there will be a press briefing here in odessa and the secretary general read. probably talk about his impressions himself. not getting that grain deal in place was quite a diplomatic breakthrough. is the grain deal working as planned so far? it's working around 30 ships, have been able to leave ukrainian ports in the past weeks carrying tens of thousands of grain around the worlds. the importance for ukraine

of this deal really can't be overestimated. a lot of people really appreciate that this deal has giving, given them back some sort of optimism. so it's really one of the big success stories are fargo cheddar's. and all that grain shipments have resumed, of course, is a big step forward for global food security. but there are other major worries regarding ukraine, not least the embattled nuclear plant right now ad safa ratio. what's the latest they are young fellow? yes, exactly. a without his cancer doesn't have much time to enjoy his applause. because the dangerous to running the nuclear power plant in separate asia overshadowing everything at the moment, especially as some information from the ukrainian security that russia mites plans some kind of fire pro occasion there very soon. good cherish is

a trying to, i have a, a demilitarized zone in place, but russia has rejected this plan completely. so now the big question is, if coach harris will be successful in helping some international inspectors get access to, to the plans, in theory, russia and ukraine agree on this bad. they don't agree on the conditions. a village, thank you very much, shar corresponded yon phillips shots there in odessa. you're watching d. w. news still to come, protecting ukraine's heritage in digital form. a new app keeps a back up of cultural science, threatened by russian bombing. our culture editor is here. tell us how it works. first, let's catch up on some other stories making headlines today. australia has criticized indonesia decision to reduce the sentence of terrorists convicted in the 2002 bali

bombings. it means the man could be freed within days if he's granted parole. 202 people, including 88 australians died when militants attacked a tourist district in bali. apple has warned if a major security flaw that could allow hackers to take complete control over devices. users of i, phones i, pads, and mac computers are being advised to update their software. apple has not revealed how many of its customers are affected by the issue. german chancellor, olaf schultz is preparing to test, apply for a 2nd time in investigation into a scandal that has undermined trust in germany's financial institutions and government oversight companies and investors defrauded the german state billions of euros through the scheme known as come acts or dividends. stripping the scandal came to life 5 years ago when schultz was mayor of hamburg, investigators want to know about meetings he had with one of the banks involved

back then, but so far he says he doesn't remember. what did she know when for years now, will of choice has not been able to shake off germany's biggest ever tech scandal when he was mayor of hom book. he met with officials from wall book, bank it. oh, with the city of hamburg, 47000000 euros for claiming refunds on texas. it never paid after sholtes met the banks. officials humbug authorities dropped their demands at 1st shoals falsely claimed. those meetings didn't happen, but was proven wrong. now he says he cannot remember what was discussed and has been keen to stress. there is no connection between his meetings and the city, backing down this growing mistrust. in his version of events, it is unlikely that he cannot remember anything from this meetings. during those

meetings or phone calls, it was about nearly $50000000.00 euro for his city in tax revenue. the whole aspect of working here with the salami tactic of just admitting what he has to admit and once more has been proven, he will admit more obviously makes it that much more doubtful that there is no memory at all. so far, prosecutors do not see any breach of the law. the scandal is hitting the headlines again now, because a former habit m p from charlotte's us party, had stashed away 200000 euros in cash. and that and peace district had received money from warwick bank before as yet. nobody knows where the cash came from. and shaw says denied any knowledge. what do you know about the cash in the former and p safe deposit box? nothing. next question. where do you think it came from? jacqueline? i no idea. i guess you know better than i do. whatever emerges from today's hearing,

it surely won't be the end of the story. or chief political correspondent, melinda crane has been following the story. melinda chantelle, all of shelters, due to testify in this tack scandal to day. is he expected to shed light on it? no, i don't think he will. he's likely to repeat what we've heard from him numerous times, including during his summer press conference just recently, where he says, there was no political influence on the hamburg finance authorities decision a not to demand at warburg repay the, the $40000000.00 plus that they had, essentially cheated the state of and he says also that this whole scandal has been repeatedly analyzed. he said a word for word in his press conference. we shown a spotlight on this. we have asked everyone, we could,

we have looked at all the documents. there is nothing more to be said, essentially suggesting that the story is at an end. but as our report pointed out, the story is not at an end. new developments continue to come to light, including that $200000.00 euro stash. but i think we're likely to see the chancellor, none the less pursue the kind of minimalist communication policy that we just saw in that report. he's known essentially for providing the least amount of information possible, but many feel that that is now coming to hurt his credibility. ok, just to be clear, this is a regional parliamentary inquiry happening in hamburg. schoultz is appearing as a witness relating to his former role as mayor of that city. he's not a target, been a criminal investigation himself and tax rog, but could this still be a potential danger for trensler? schultz. berlin?

yes, it could. as you said, the hamburg prosecutor repeated this week, the child is not currently a target of the investigation, but it's an ongoing investigation. that's why he speaking today before the committee and questions continue to arise. and as i said, those questions do also concern the credibility of the chancellor of germany, this very minimalistic communication style that he adopts can look as if he has something to hide. and that is problematic because it goes to the question of whether left schultz can provide the kind of leadership and from transparent communication that this country needs as it faces multiple severe challenges. so it may not at the moment be a legal problem, but it definitely is a potential political problem. and this scandal may not be uppermost on the minds of voters who are worried about inflation and soaring energy prices. none the less,

certainly for the social democratic party that considers itself the party of the working man and woman. the possibility that the chancellor might have been soft on financial wrong doing by big capital could have very unpleasant political repercussions including in regional elections in october, in the us be des stronghold of lower saxony. when to thank you very much, shar she political correspondent, melinda. kris europe has been experiencing extreme weather conditions in a form of a heat wave for several weeks now. temperatures have been above the 40 degrees celsius mark in some countries the extreme conditions have brought climate change back into focus. in our next report, our correspondent, good, our current travels to the greek capital athens, to see what authorities there are doing to reduce the effects of very high temperatures. and laney merely always has her water bottle with her in

summer. she's used to the dangerous heat waves in her home city. she is the 1st chief heat officer in athens and across europe. it's her job to get the greek capital fit to face the challenges of climate change. she's on her way down into the depths of the city with someone from athens waterworks. it's also a journey back in time. the subterranean tunnel, almost 20 kilometers long, was built by the roman emperor, a hadrian. in the 2nd century, near a village is planning to have water flowing along hadrian aqueduct. again, engineers are already working on her idea. they are planning to greet 20 specific points where the, where they tap into the water into the green new parks. a green belt across athens is intended to make the city cooler and the pleasant mere villi. once more

parks. she's particularly proud of these japanese south space. she's friends with the landscape gardener. he created it. we don't have a lot of barks and, and green spaces. and we have a lot of old people. the fact that the surfaces are we have a lot of surfaces of tend to heat up. we have a lot of cars that produce even more heat and air conditioning produces even more heat. so it's actually a pretty deadly mix in, in greece, extreme heat waves with highs of over 40 degrees are almost always accompanied by forest fires. and they also threatened the capital. in mid july fire reached athens in northern city, limits thousands of homes with gutted experts fear that large parts of the city, home to 4000000 people could be uninhabitable in a few decades. studies already showed that heat waves are responsible for

a rise in mortality among the elderly. in particular, the chief heat officer is seeking advice from the red cross, red cross representatives from australia explain, they have their own emergency plan. when temperatures reach up to 50 degrees, we are preparing people to be able to help her people before they get really sick. so that we can tell them what to do and if they start having symptoms, somebody is there that can answer a phone or can be next to them to help them. so they don't end up in the hospital. but not all athenians see it as a life threatening problem and i found amok. a few of these here think i'm going to vomit. i just stick my feet in cold water or carry on it all by unit. now things is more and more unbearable in summer. we don't have any rivers and the surrounding area has usually already been scorched. mirror really is planning to stick by her home city. after all, she says it's hardly the 1st crisis that the city has faced in its practically 4000

year history. now an ecological disaster that has puzzled, has been scientist from poland and germany for weeks now. vast numbers of fish washed up dead in the river that runs between the 2 countries. the order nelson researchers think they may have an answer. ah, the danger is invisible to the naked eye. a microscopic species of algae could be to blame for the man's deaths, a fish in the river order along the border between germany and poland. officials on the german side alone have recovered 36 tons of dead fish. on the polar side, the fire department reports nearly 100 tons. researchers have been trying to find out why now their tests have discovered an unusually high concentration of the micro algae, species prim newseum part of them, which should not even be in rivers, but water experts think the algae is toxins could be behind this ecological

catastrophe. di they go into the hills and from there they can destroy blood vessels, but they also attacked muscle and amphibians on, since i've also seen dead muscles on the odor as well as dead fish, i believe this is the cause of the on their processes food. this species of algy normally lives in river mouth were fresh and salt water mix. that's why some scientists suspect that salt discharge into the odor river might have led to the buildup of algae. it could be at least another week before this is clarified. to get an expert view on this saw daniel healing is a professor whose research focuses on aquatic ecology. he's at the university of disparate essen, thanks for being with us from as a healing. how likely is it? do you think that algy are responsible for the massive fishkill in the order river? so 1st look me on the line that i was not personally involved in this investigation

. but to me it's on very likely a very likely calls. so we observe. observed in the beginning of august messes from increasing conductivity of through the older conductivity as an indicator for the fall conference. and about a week later, apparently we had a very high concentration of our so called ology bloom. and these are people who are generally very dangerous for fishes, especially in the summer. so if it of the oxides or if the old you have caused in other ways, this is still to be investigated, but it was most likely the play be called ok, so plausible for sure. if it is algy, do you think it would be attributable to human activity and pollution? most likely not. so the, the ology the colleagues at the b building have identified us through it just sets

in the presentation of ology that you will talk, find sometimes that are dangerous proficient all of all organisms that have chills . so for, for humans that all of all mental, it is less likely that we are affects some buff. let me also underline that's well, this question. if talk science play a role, it's not just clary flights, but such a mess with all g noon has in any, in any case, us strong effect on fishes. so what he also observed, the ph value of water, it's once a buff or the value of 9. and this is always critical fish. because under these conditions of massive photos and teasers of all g, but call centers increase in ph ammonium, which was august. and the water is trans phelps to ammonia,

so it can simply be also toxic nation by ammonia. this quote also has been caused by the ology and this is for my point of view of the most likely pulse. okay, so it's clear that more research has to be done to find out what exactly is happened there. do you think, given what you know so far, that it will be possible to restore the river to full health because this is an important river? yes, certainly it also has a very important fish population also with several species that are just occurring in this room. so hoping to mix these them at least to was it was also a country free introduction. we'll come, we'll see it of a starch and spc and suddenly also affect us. so, um, i think, oh, the riggle will be cover because see, and tributaries of the river have apparently not affect us and the south me also some fish have survived. and also the invertebrates set of a will have survived on which can be kind of initial false for rebuilding the

population. on the other hand, it's on the lines very, very strongly hold close to ecological tipping points all or reverse and he's very health somewhere else. littlest charge, there's very high temp richness. that all the organisms of lifted rebel. they are all almost very close to collapse. all right, if then for example, even while they affluenza salt or something like this, now comes, comes on top, and then be very often if he is sort of the skills professor daniel herring, thank you very much. thank you. well, russia's war on ukraine has laid waste to ukraine's cultural heritage. indiscriminate bombing and shelling have damaged or destroyed historic buildings, museums, and religious sites. but a new project promises to keep ukraine's culture safe, at least in digital for russia's missiles threaten ukrainians, lives,

and also their cultural fabric. for months, volunteers have been working to save ukraine's heritage from russian attacks. now a new digital project offers a different way to preserve that heritage. 3 d scanning up back up ukraine, turns ordinary ukrainians into digital archivists. the app turns their photos into 3 d models and on tag to their precise location and save to a secure online database in the cloud. when albums can reach architect and key of resident maxim, communion has already contributed more than 100 smartphone scans to the project. yes, but who i should say put it up when i hope this project will significantly help ukraine and its future generations still a good. so far, yeah, because if a historical monument, a sculpture or historical building is destroyed,

it will be possible to restore it in the same material in size. everything can be identical. what will the in these so even if artworks are destroyed, they won't completely disappear. the apps founders want to safeguard ukraine's culture from the horrors of war. it can be used as sort of as a reference for reconstruction. it can be used as a cost and form, and it can also just be used as a form of documentation. i guess a form of preservation that is, it technically will last for ever downloaded more than 6000 times the app is on its way to preserving ukraine's irreplaceable cultural heritage. and with me in the studio for more is david levitz from d w culture. david, this technology is impressive, but it can't protect ukraine's cultural heritage from being destroyed in this war that is going on. it can only document it. why don't you begin by telling us how

much of a threat ukraine's cultural heritage is facing? well, ukraine's cultural heritage is under attack like the rest of the country. the country's culture ministry has that well over 400 cultural sites and objects have been damaged or destroyed by russia's war of aggression. and unesco confirmed a lot of these cases, including 76 religious sites, 13 museums, 34 historical buildings, 17 monuments and 8 libraries. and of course, we don't know how the war is going to continue or how, or when it's going to end. what's important is to document can historical, cultural heritage and historical heritage in ukraine, both so that it can possibly be reconstructed in the worst case, but also to be able to investigate possible war crimes. it's important because it is a war crime to intentionally destroy the cultural heritage of a country or a people. and that's what you crane says the russians doing. they say that russia

is intentionally targeting their cultural heritage in order to erase the ukrainian identity. ok, so there's a forensic component to this documentation exercise up. let's talk more about the app that's at the center of it. it's called back up ukraine. how does it work? well, basically the user and it could be any user with a smartphone and you crane takes a lot of pictures of an object that works best with sculpture is actually with bigger buildings. you really need a drone or at least a very tall ladder, but it works very well with sculptures and basically you take a lot of pictures of it, these are uploaded and then an algorithm puts the pictures together and it creates a 3 d model out of them now the 3 d models in and of themselves are not that new, but what is new is that this technology is accessible to normal. people who don't have very expensive equipment. so that's, that's actually very exciting. it is exciting. this 3 d scan technology that's

being used in ukraine. could it be used for something else for other applications to, to help or help save cultural parodies elsewhere? well, of course this app is made specifically for ukraine, but it's very feasible that the same technology could be used in other wars and it could also be used in conditions that are not conflict, but where cultural heritage is threatened for structural reasons. like one great example is the great wall of china, where they used drones to create a 3 d model of the great wall. and the drones were coupled with an algorithm that checked for weak spots. and it even suggested how those weak spots in the structure could be fixed. so there's a lot of, there's a lot of potential for the 3 d modeling technology to bring it back though to wars zones. and specifically, the case of ukraine was also really important is when you have these digital backups that they are stored securely. because of course, the internet, the internet infrastructure is in the real world. there are real servers and real

hard drives that are susceptible to attack to war. so actually, there are a lot of people in ukraine now librarians, archivists, and programmers who are busy day and night transferring the digital archives of many of ukraine, cultural institutions to servers outside the country to, to preserve also the digital documents. david, thank you. fascinating story. david levers from d w culture ah, ah, with
