commanders lead the defense of the port city of maria poles through a months long sage. early in the war as russian forces captured, the city, the ukrainian defend is held out in tunnels under the as of style steel plant. he finally ordered them to surrender in may last year. the commanders were taken to turkey as part of a prisoner exchange deals and was supposed to stay there until the war ended. there was no explanation for the change of plans as the command is boarded alongside ukrainian president full of them is zalinski. on his way back from mixing with his tuck, his counterparts. the kremlin has slammed. the command is returned home saying birth cave and ankara has violated the terms of the agreement. for ukraine, the commanders have become heroes. the return came on the 500, the day of the war. president zalinski released this 40 inch of him visiting snake

islands to mark the day. the black sea islands games knows righty when ukrainian defenders refuse to surrender to a russian warship. ukraine lays a recap to the island. what just what i want to thank each of our soldiers for these 500 days or night here from this place. the place of victory as the walgreens on the crating leda. remember those who have died and the symbols of ukrainian defiance that marked those early days of the war. dw correspondent dorian jones has more on why turkey may have let the poisonous go of the. well, there really hasn't been any explanation from any of the involve policies, the new ukraine military, if you have explained why now that they have seen these commodities have been released. but the timing is from maximum effect for propaganda. victory for ukraine coinciding the 500 the day of the complex and also at the same time as ukraine is

launching this very important counter offensive against russian forces. one of the release come on the set that they will have a say in that indicating they expect to take part in this offensive against russia, which will lead to the infuriate, must go absolutely outrage to about this. the peasy got no early warning about this decision, and this coincides also with the one following his way behind ukraine speed to join nato, which would be a key issue at the nato summit in vilnius this week. so this does appear old to be a delta of attack against most co, and now police will fuel speculation, the east, possibly one distancing himself from boot in the russian president particularly may be off to this box in a mutiny. again, scooting that's was the biggest threat from coaching go pulse cleared. one sees him is we can all could be sending a message saying that he wants to violence. his relationship between on crow i must go to evelyn. the motivation is it certainly has delta flow to on,

so open position as a, as a balancing act force between ukraine and russia. and that is a bit surprising because one of the issues that was discussed was the landscape when he met with us. what's, what's the prism of exchanges, and possibly even the return of you crating children that are being taken by russian full. since i've been invited to crate, all of that's not going to be very difficult going forward. well, dorian, of the breaking this, present a deal, and those are backing ukraine's nato ambitions. how will add one facebook then when the to meet next month and how, how will you and your other deals like the grain deal, for example, remain in flight as well? i think the biggest concern will be this great in deal. uh, we've just seen of a 13000000 tons of grain being exported from ukraine to the well, very important, particularly for companies like africa that depends on this great. that's due to be renewed next week. the deadline is coming up in russia, so there's no, it's very concerned about renewing it. it has its own, the major grievances,

and they said they've those grievances onto dressy, won't extend it. now it's on hub positions himself as a person that was possibly key to getting that deal of extended. it was him along with the united nations that initially broke at this deal. all of that now, the big question marks of, of the one's ability to persuade, most go to extend that they'll give them the fact the most go is pretty furious over this decision to release these uh, come on. does such a critical moments in the conflict? yeah, well the, the conflict has and solely the screens here will have many countries in africa and across asia to watching closely. the w correspondent, dorian joins in is sample. thank you for the analysis. countries across the globe are grappling with extreme heat waves. the side has to say last month was the boldest june on record by a substantial margin, and the average temperature of each 10. unofficial regular height is weight. it's a climate change and the venue with a patent. the push temperature is even higher. the united nations is wanting

governments to take precautions to prevent that's caused by the intense heat struggle with who is an earth system scientist. i asked him how wide we should be about the heat waves and pots of the boat, as it is something definitely, what are you about to worry about in terms of impacts? not the young human beings, especially in the global south, like india, for example, or africa and also other species, livestock, fish of these portals by diversity in general. so it's something really need to worry about specially depending on where the existence as of whether or anything we have seen before with the so called analog states. we have not given the use to them, so we have to worry about that. okay, so imagining by diversity and lives. okay, are we talking the problems impacts on agriculture for example, when it comes to food change?

yes. so the combination of amino which brings temperature early on in the year and then affects the rain mosley august fusion, especially over parts of india and the new york mania homes. and so on. the last, the same property yields a and the lead arrival of the monson can affect just how much sewing actually gets done as well. and you will get lots of supply chain impacts as well. because what happens in busy beloved like what happens in the philippines in terms of the market change. similarly, export a price and be done offering everything will be affected. so use drop and then some flights in gets picked up. so the global aggregate, the moment definitely what you got it if we continue to see such effects. well, is this just the weekend heat wave or should we be ready to face an extremely hot summer? in general, i would not jump on weather events of a few days to plan for the future, but the combination is that we have background,

global warming, which has a back to amenities which is warming already several regions of the planet. then we have the amino coming in and adding onto that the noise in general known as a mini global warming because he's, that's been accumulating in the ocean for the last few years, especially since last the last name is it. when he gets when he leaves into the atmosphere, so we'll add global warming in many places. but the other thing that's really, really terrible, this theory is that by now to june, more than 3 times the number of factors have been burning around the world. and more than 3 times the amount of the problem has been released. wow. so this is really adding to olivia basically from the nation. and we're, i'm the estimates all of these cascading events can combine to create subsidies, ask those situations. so in that sense, the combination has to be looked talk for in the next few weeks to few months

because the many fires, especially in canada, been born in the we have to watch out for these for the next 2. certainly. so your reference to c o 2 is that, is that the direct link, the, to global warming that's causing these heat lights. everything is now happening in a wallet. it was so everything has the contribution from global warming and the dry s and the increased temperatures makes the atmosphere already those fee, so it begins to step out of water from the reservation. so when do patients lose this more water than normally in a wallet? i can steer, so all these things that are directv and direct the related to global warming, and we don't need to always worry about with a global warming. did it work and how much was because math, everything is happening in a lot of my work. so we must, 5th inch pads and we'll go down from the university of maryland. thank you very much for timing in here on the w use. thank you. and just briefly us

women focused on making repeat of says she'll retire at the end of the football season. she's kind of preparing for the women's world cup with our teammates in california for full fine twist radio with they'll again be favorites for piano as well. not full of work on. so for the next up ballot reported, look, sat the female comedians, challenging the status, quotes in pakistan. i've been presented. monica joins, will have mobile usefully excel by the name, guardians, of truth. my name is junk and and i have paid almost every price of being enjoying this in the country. like to tease.
