you know. this is d.w. news line from berlin the u.s. pulls its troops out of northern syria to pave the way for a turkish attack as turkey prepares to sweep away kurdish fighters from the syrian border kurdish groups say washington is abandoning them. also coming up environmental activists staging drastic action to fraud tension to the climate crisis in cities around the world members of the group extinctions were valiant aim to paralyze traffic in occupied buildings to get their message across. and the nobel prize for medicine goes to

a trio of scientists for their groundbreaking work on oxygen bottles and cells discoveries that lead to new strategies to fight cancer and other to. i'm serious almost gone it's good to have you with us turkey is set to launch its long planned offensive against kurdish fighters in northern syria the u.s. has reportedly started withdrawing troops from the area clearing the way for the incursion to go ahead now u.s. troops were stationed close to the border with turkey where they supported kurdish forces in the fight against the so-called islamic state turkey sees these kurdish militias as terrorists on sunday kurdish groups in the region held a mass demonstration against the turkish offensive the they say that the u.s. has abandoned them now washington says it will not get involved in turkey's play and let's get the latest on the story that is really

a han is in istanbul for us hi yulia why is this happening now. well this is basically u.s. president donald trump said only making way for turkey's military operation in the north and syria this definitely comes as a surprise and it follows developments late last night a phone call between trump and turkey's president. to which the white house published a statement saying that turkey will soon move forward with its long planned military operation in north east syria and that u.s. forces will not support or be involved in it and what we're seeing on the ground is that u.s. troops have started in the morning withdrawing from areas in the north and syria areas that are so far controlled by syrian kurdish militia and this is actually you know a major shift a stunning reversal of u.s.

policy in syria because washington had so far significantly supported these syrian kurdish militia and considered them the most effective group in the fight against the so-called islamic state while turkey actually considered as them terrorists and that was the the reason for major disagreement between washington and ankara in the past months and now it seems ankara god what it wanted what will happen now uli or are we going to see turkish forces move into the area. there are actually many many on oncet questions right now concerning the scale and the time frame of this turkish military operation the turkish military has reinforced troops it has pulled together and pulled over more military equipment so they say they are basically ready and they are just awaiting orders but it also remains to be seen what's coming next from washington because it's safe to assume

that president trump doesn't have full support on this from the administration from some very high ranking and important people within the pentagon it's safe to assume that this is basically president trump coming up with a decision that needs further talking in washington so it's going to be interesting what we'll hear next from washington and you'll hear just quickly here the kurds say they feel like they're being abandoned tell us more about their reaction. well they have condemned the u.s. has moved there saying that and i quote them here it will have a great negative impact on the fight against the so-called islamic state they are not the only ones a very concerned the u.n. the u.n. secretary and coordinator in syria has also warned parties of causing a major displacement off civilians in the area he said we don't know what's going to happen next but we are prepared for the worst so many concerns you many open

questions all right our correspondent reporting for us from istanbul thank you. and turkey's planned offensive has put residents of northern syria on edge they are bracing for violence but many are determined to stay even if it means risking death . every time one mohamed goes up to his roof he feels uneasy the border to turkey is less than 100 meters away from the people watch him occasionally gunshots fired but the 19 year old says it doesn't intimidate him. we won't leave our lands even if a huge hassle we'd rather die. as a border town with a turbulent history 350000 people live here 60 percent of the population are kurds the rest are ribs it is considered the birthplace of the kurdish militia group. in

2011 they rose up against syrian president bashar al assad driving his troops out of the city a year later they defeated the jihadist al nusra front hundreds of kurdish fighters died the people here are proud of the independence they gained but. we're happy and content more than ever before without the kurdish forces keeping order here. but their independence is under threat once more turkish president retch up type add on has moved troops and weaponry to the border he sees the y. p.g. as a terrorist organization that needs to be wiped out. at a party meeting on saturday he left no doubt about his intentions. the operation is imminent maybe today maybe tomorrow the road going to peace efforts.

the kurds had tried to appease out of a safe zone was a stablish along the border spanning 100 kilometers an agreement was reached between turkey the usa and the kurds in september but the y. p.g. withdrew from that agreement now turkish and u.s. troops patrolling the safe. lies in the middle of it. mohamed muslim is assembling metal parts for his neighbors the kurds has seen assad's troops withdraw jihad is fighters defeated now the 35 year old fear is an invasion by turkish troops. more than an enema put them in a safe zone should be safe but this one isn't it's a recipe for chaos. also worrying residents the ones plans to resettle 1000000 syrian refugees from turkey to rise a line but there is talk of relocating kurds elsewhere to accommodate them.

we haven't left our homeland since the war began at a minimum we were shot at by rockets and by grenades but we stayed and we will stay even if we have to die on one of. the people of russell and refused to bow down after all they have been through even if they would barely stand a chance against bad ones army. let's check in now on some other stories making news around the world at least 13 people drowned near the italian island of lampedusa during a nighttime rescue attempt officials say 2 patrol boats were approaching the overloaded migrant boat in rough water when it capsized the coast guard picked up 22 survivors it's not clear how many people are missing. hong kong police have arrested and charged 2 protesters for defying the ban on wearing face masks at demonstrations there the 1st 2 people to be charged under the new law that bans fuel days of violent demonstrations in the semi-autonomous chinese territory. and

opposition parties have taken the top 2 spots in kosovo as parliamentary election official results show the leftist defendo see a party winning with 26 percent but it will have to find coalition partners to govern the vote was called after the prime minister resigned in july when he was summoned to appear before a war crimes court. the environmental action group extinction rebellion has kicked off world wide protests warning of an environmental apocalypse protest started in australia new zealand with police there making several arrests in london more than $100.00 protesters were arrested after blocking the streets here berlin activists have gathered at a major intersection in the city stopping traffic and marching towards the government district demonstrators want a world leaders to take stronger action on climate protection they want net greenhouse gas emissions to be cut to 0 by 2025 and let's bring in our correspondents covering the story forsberg at moss is in london and simon young is

here in berlin good to see you both back at let's start with you in central london what is going on there. well i mean you know interest of the square and as you can see behind me the square is really roped off and on the iconic law in ca on the square there are extension of rebellion protesters so most of the central london is traffic free and the protesters have attended some plays into a giant playground where people are playing cricket there is a lot of singing and dogs singing peaceful protests but as you have mentioned there have been some arrests over 100 people have been arrested i saw someone being arrested. as i've spoken to several people who said well you know it's it's it's a risk that they are willing to take it's something they really strongly believe in and even some pension i've spoken to the older people i've seen here actually on the streets and even the. brightest bulbs i've prepared to go to jail because i really believe that i must be

a change of climate policy. ok simon what about the scene here in berlin how big is the protests here today. yes several 100 people sumi here gathered here near the victory column right in the heart of berlin not far from the brandenburg gate and normally there'd be plenty of traffic thundering through here on a normal day but today it's a scene of festivity i would say with protesters but also some very imaginative costumed procession people pointing out threats to species which are threatened with extinction by climate change and people making all sorts of different points related to that there have been speeches they've been singing and chanting of slogans and people are very motivated i should say and relaxed atmosphere just now as people wonder whether the police might move in to close this protest down but let's listen to the words of one of the activists we spoke to earlier.

i think it's important because if you look at how politicians are dealing with the climate crisis now i don't see how we could stop this i'm afraid that we won't have the same living conditions in 20 years because our earth will be destroyed in my view this will destroy us too i don't see why so many politicians don't understand this what so simon picking up on that question of what politicians are doing in other german government agreed on this big 54000000000 euro climate package just 2 weeks ago but that has now and that has been criticised and that is now also been watered down tell us more about that. you know this is a dispute really about what targets should be set and what targets are meaningful a lot of people here and other climate activists elsewhere already were saying that the government's proposals to protect the climate didn't really go far enough according to media reports of come out today it seems that they've pretty much

dropped the idea of fixed targets for reducing c o 2 emissions by 2048 also have adopted any firm promise to reach climate emissions neutrality by 2050 the government says it's important to take the whole population with them to develop policies that you know everybody can get behind and that it's goals and now for 2030 but of course a lot of people not just here say you know that really doesn't go far enough and it doesn't go fast enough much more drastic action is needed. ok let's come back to you there in london you know extinction rebellion is a group that has carried out various very disruptive civil disobedience protests what do londoners think of this very. well yes law than of course is an extremely busy city and central london has been pretty much blocked off for traffic most people i've spoken to i have to say have been fairly

sympathetic a lot of cyclists have been going pause they were cheering the processes on by speaking to one lady who was a little bit more muted she said well what about those people who want to go get along on the pos they already knew leaving it going the lifestyle but they call and get straight and one lorry driver who was frustrated because he wanted to go home he had a massive lorry and he had to just turn it around in the midst of all the protesters but even he wasn't scathing he was just a little bit grumbly he said well all the countries they have to do more in the side now they have to do much more than we do but then we couldn't discuss discussion with the protesters and and you know he could see the point so i think a lot of people are willing to engage but of course they're also with just a few make that call and go about their normal lives today all right our correspondent on the ground in london and simon down in berlin thank you both. of

you watching d.w. news still to come the world athletics championships have been marred by controversy as it wraps up in doha qatar you took the last minute. a 2nd whistleblower has come forward in the case claiming to have 1st hand knowledge of a phone call one hell of a time we're going to show if this is what they want to. get ready people have had enough if you're in a position of power you should take your position of power and use it to your advantage and what you're doing is you're dividing people country and it's not worth the time or the effort when we could all be uniting which is what we're standing for the. and i did state allentown pennsylvania alliance in a highly competitive political district the democratic and republican parties are on equal footing here but in the last congressional elections the district chose a democrat congresswoman susan wound regularly holds town halls to check in with her constituents these public meetings are somewhat of

a microcosm murray in the deeply divided state of politics in the usa itself i wonder colleagues in congress are pursuing impeachment which according to some polls the majority of americans do not support. i didn't come to congress to pursue an impeachment inquiry our president had with a foreign leader where he used his office to attempt to extract information about a political opponent he crossed the line clearly and he's too dumb to even know what he did which is shocking a lot of polarization divisiveness anger people doing crazy stuff because appalled by me i get in the political discussion with everybody about 2000 kilometers southwest of allentown is the written louisiana republican congressman mike johnson is not worried about his job his district is staunchly republican but even here there seems to be disagreement especially on the topic of impeachment i believe

didn't feel worthy to teach me hope that the terms turn for a vote on this that you'll at least seriously consider you might be sure that no one was even like you 'd if you were not in the last 2 they went to it's on that you did not commit a crime and there's a lot of people have a lot of issues with the president and his style and his twitter and go a lot of the right i mean to date no one has yet stated any specific crime or voters here are split on trump impeachment but they are united in their opinion that political fronts have become too hard for the division goes all the way down to fair. all across this country. and friends and those divisions are are real and they're having an impact so we try to disagree without being disagreeable you know we try to do that in community you can have family you can have community if you can't respect each other with so much political division many here may see

prayer as their only hope. the nobel prize for medicine has been jointly awarded to 3 scientists from the united states and britain they've been chosen because of their pioneering discoveries of the way cells sense and adapt to oxygen availability it is a 1st prize announced by the nobel committee this year. turning food into energy a process that would make possible without oxygen. but oxygen levels can vary dramatically in the body. when you exercise climbed up to high altitudes or are pregnant with the child amounts of the vital gas that they were both a metabolism go up and down. to continue working well. have to be able to adapt to discharging levels of oxygen but how does this addictive process work. 1000000 kaylin super direct cliff and. discovered this mechanism.

when i would say the benefit is understanding this fundamental mechanisms by the practical applications are yet to come and that's. what's so great discovery that it opens up so many possibilities and really creates new new research areas for example in wound healing on treating patients who suffer from severe in the media or even cancer. kalen redcliffe and samantha need to ground work for a whole new era of track development want it is now starting to address many dangerous conditions that modern medicine seeks to heal now we have derek williams from the debut science but this hi derek tell us who these 3 scientists are and why they want these 3 researchers back in the 1990 s. looked into the genetic reasons for for how cells react to the availability of oxygen now every organism on earth needs oxygen we need them for fundamental

metabolic processes and actually an earlier recipient of this prize back in the 1930 s. you won the prize for describing the process of how of how that works how food is turned with the help of oxygen into energy but the question of availability and how the cells within the body react to availability of of oxygen that was something that was happening at a genetic level that nobody really quite understood and so this work is really about that fundamental process how does the cell know there's not enough oxygen there or i have enough oxygen in order to do a whole wide range of things including things for example an exercise to provide enough oxygen to the muscles at the right time in order to get the energy to the muscle ok so very important work was it expected that they would win. well it's it was surprising i read the websites like everyone who works in this in this particular area i read the websites and the predictions and and they weren't in the top 3 but that said it's no surprise that it is a surprise because there's so much fantastic work that's out there that's actually

worthy of a nobel prize and and really you can break down the nobel prizes into sort of 2 categories one is something that's delivered is research that's delivered a tool for example and antibiotics or something in that direction or the fundamental basic research that tells us how things work and so much of science is about learning how things work and that's what these researchers. they taught us more about how this particular process works which is so fundamental to so many metabolic processes so what does this research actually deliver it to us and how can it be used well there's a there's a whole list i made a list metabolism exercise embryonic development immune response wound healing infection heart attacks the list goes on and on as i said oxygen and its availability affects everything really and when it comes to life and so it diseases like anemia but also cancer for example in the drugs industry cancer cells cause

through using some of these fundamental processes they the tumor can call cause the body to create blood vessels to feed the tumor and by certain drug companies that have focused on those mechanisms if you can block that that development then you can possibly stop strangle the tumor or at least contain it and so they would have been able to do that without understanding these fundamental genetic things that are going on when it comes to oxygen availability and that's what these researchers did all right eric williams from d.w. science i thank you so much for joining us here in our studio. to sports now in the world athletics championships in qatar have come to a close every 2 years the top athletes of track and field take center stage the u.s. dominated the final day of the global event but did not manage to fill the seats palin the day of finals on the final day of a competition marred by low crowds and complaints about the heat was begun with a win in the long jump for germany's malenka me humble was world championship gold

of the championships to leave the us with a table top and medal haul of 29 was. in basketball the houston rockets have apologized to china for a tweet that supported hong kong's democracy protests the tweet from a team official has since been deleted but it read fight for freedom stand with hong kong now that lead china's state broadcaster to yank rockets games off the air millions of chinese fans have been in love with the n.b.a. team since former player named 1st joined them in 2002 the rockets general manager darlene mori has since tweeted he did not mean to cause offense to fans and corporate sponsors but some in the u.s. including a presidential candidate criticize the rockets for bending to beijing's pressure. let's get a reminder now of our top stories here on d. w. the u.s. is reportedly pulling its troops out of northern syria to pave the way for a turkish offensive against kurdish fighters there kurdish groups say washington is
