this is the w.'s life rebel that the u.s. pulled its troops out of northern syria 5 on the way for a turkish attack as turkey protests to sweep carriage fighters away from the syrian border guards accused washington abandoning them also on the program. environmental activists research the streets george tensions of the climate crisis extinction rebellion is taking action in cities around the world but paralyzing traffic and occupying buildings. the nobel prize for medicine goes to a trailer scientists for their groundbreaking work of oxygen levels and cells which

is led to new strategies in cutting calories out a little since just. i'm from welcome to the program turkey is getting ready to launch a long planned offensive against kurdish fighters in northern syria the united states has reportedly begun to withdraw troops from the area clearing the way for the incursions us troops were stationed close to the border with turkey where they supported kurdish forces in the fight against the so-called islamic state turkey however regards the kurdish militias asked terrorists on sunday kurdish groups in the region held a mass demonstration against the turkish offensive accusing the us of abandoning washington says it will play no part in the turkish operation. so all of this

complicates an already complicated picture let's see if we could uncomplicated flu with the doubly correspondence all of a summit in washington and you'll be home in istanbul welcome both let's say washington with you all of a why is this happening now while we're nearing fill the 2020 election and that is a very crucial moment in time because as you know there is an impeachment inquiry against the president going so he's under severe pressure domestically and what he's trying to achieve right now is to get some foreign policy successes on his record he has hardly had any so far and withdrawing troops in general from foreign conflicts and crises has been one of president trump's core election promises that he's made to his voter base that is just like almost the majority of the americans increasingly tired off war so he's definitely trying to get some credit for that president trump also repeatedly said that he believes that isis this defeat it he

was very much challenged for these statements even from within his own ranks and another very important aspect here is the financial situation when president trump takes to twitter on this matter he always stress is how much money the kurdish fighters kurdish fighters have received how much equipment and that this all goes to the expense of the american taxpayers ok so the president gets to deliver one of his 1st campaign promises there the united states used to hot it is double what this turkey wants in syria. well 1st of all for president bad on this is a diplomatic victory because apparently he managed to convince donald trump to make way for this turkish military operation in syria's northeast despite resistance within the u.s. administration turkey for a long time has been pushing for establishing what prison at one calls as safe sewn

in syria's northeast the main objective here is clearing the turkish border of syrian kurdish fighters which ankara considers a terrorist prison edwin in recent weeks has also promised to resettle millions of syrian refugees over there now we didn't get a specific timetable or information on the scale of the planned operation yet from ankara but u.s. troops have in the morning started withdrawing from these areas in the north and syria so both. resistance with. administration if you could. what i've read is that president trump this actually goes against vice. and that's not even you phil that's right and even when he announced the withdrawal of his troops from syria the 1st

time in december 2018 that led to a lot of criticism from within his own ranks and at the time the secretary of defense jim mad as resigned over that decision as an act of protest he has been receiving criticism of course by his international partners and from within his own party lines for instance senator graham lindsey graham one of his most avid supporters when it comes to the impeachment inquiry who is always defending the president on that matter and on that and has now said that it was an impulsive decision of the president to withdraw the troops from syria and he also expressed concern about the about his take that isis would be defeated of a president seemingly did not was not really impressed by any of that and is moving on with his decision so you do you hope we have the goods who were helping the united states fights isis we have turkey who wants to stop the code from

establishing themselves in the south of his country so the could still want what the kurds want so who will they turn to to assist them to get out now that the u.s. has let them down. well the syrian the kurdish a fighters that has strongly condemned the u.s. has moved the decision here that's hardly surprising offer all they have been for a long time considered not only by the u.s. bought by the international community basically as one of the most effective groups in the international battle against the so-called islamic state now they are basically feeling verner able to a turkish a soul to their impression is that the u.s. has turned its back on them they have also warned that this could risk the fight against isis even more they say that many isis fighters are still hiding in

the area and they're trying to break out other ice's militants now washington says it will be turkey's responsibility from now on to deal with these isis militants and we haven't heard from ancora yet how exactly it's things to deal with this challenge. for joining us. thank you. the fanciful residents of northern syria on edge but despite the impending violence 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 their people watch him occasionally gunshots fired but the 19 year old kurd says it doesn't intimidate him. we won't leave our land even if the huge task

we'd rather die. is a border town with a turbulent history 350000 people live here 60 percent of the population are kurds the rest. it is considered the birthplace of the kurdish militia group y p g 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. 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 tired out of one has moved troops and weaponry to the border he sees the white 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. peace efforts. the kurds have tried to appease a safe zone was established 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 are patrolling the safe. lies in the middle of it. mohammad muslim is assembling metal parts for his neighbors the kurds has seen assad's troops withdraw your hardest fight is defeated now the 35 year old fears 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 there's talk of relocating kurds elsewhere to accommodate them. not an amended plan and we haven't left our homeland since the war began we were shot at by rockets and by grenades but we stayed and we will stay even if we have to die. the people of russell i refuse to bow down after all they've been through even if they would barely stand a chance against bad ones army. ok let's take a look now at some of the other stories making news around the world at least 13 people drowned during the nighttime rescue attempts near the italian island of lampedusa officials say 2 patrol boats were approaching an overloaded migrant boat in rough weather when it capsized the coast got picked up 22 survivors the exact

number of missing is no no. police in hong kong have arrested and charged the 1st 2 protesters for defying a new goal against wherein facemask demonstrations the ban has fueled days of violent demonstrations in the 7 autonomous chinese territory. a 2nd whistleblower has told intelligence officials of president trump has abused his power u.s. democrats leading an impeachment inquiry are now investigating whether mr trump pressured ukrainian president vladimir is a landscape to investigate his political rival joe biden and mr biden has some. weight. now the climate activist group extension to extinction rebellion has begun a series of global protests to pressure governments to do more about the climate crisis the demonstrations began in australia and new zealand more than a 100 protesters were arrested in london here in berlin activists blocked

a major city intersection the demonstrators want world leaders to cut net to greenhouse gas emissions to 0 by the year 2025. they call themselves rebels the activists calling the group extinction rebellion says civil disobedience is the only effective way to draw attention to the climate crisis. we decided to do this because for the last 3 decades demonstrations and petitions having to achieved anything even fridays for a future the core of the climate movement doesn't achieve anything with their registered demonstrations so we have to go further it's our duty. and central berlin climate activists have gathered at the iconic picture a column. and these demonstrators that you can see behind me have been protesting since the early morning hours they have blocked the streets so that no car can come

through and they told me that they will keep protesting until the german government declares a climate emergency. extinction rebellion activists have also turns out unveiling to new zealand and the dutch city of amsterdam. and london police arrested several activists yesterday blocked the city's main roads. and berlin police have been taken the less a fair tactic so far reactions to the protest a mix. i usually get are. by bicycle i think everyone should do something to protect the environment if they can. you have a difficult balance traffic is already stressful and when i have to make a detour because of the protests i don't know where to go it's upsetting.

regardless of what other belinda's think these protesters want to stay here as long as possible to keep up the pressure on the german government. so despite all their attention grabbing do these acts of civil disobedience achieve anything more than headlines brian dirty is professor of political science at england's at kiel university welcome to d w professor we're used to climate protests now is there anything different about extinction revalue. certainly is i think what's distinctive about it. is the number of people who are prepared to commit to doing much more radical action than was the case before so you had you quoted. interview to demonstrate you talked about the relatively ineffectual impact of marches. and i think what that's what's really distinctive about extinction event in that. there is a sense from those protesters that. the time for change in your own personal lifestyle

has gone and there their focus is very directly on government and the need for government to act and then we heard in the report to them contrasting the way they operate with the likes of gratitude fridays for future campaigns. if your opinion is either approach more effective a changing of government policy the nice fridays for future campaign or perhaps that nasty extinction rebellion civil disobedience. well i wouldn't want to put put it in those kind of comparative terms in fact i think part of the reason we're now seeing extinction rebellion spreading is in fact it is a lot to fight is for the future as well the 2 should be seen as complementary really and also. one of the really interesting things about extinction about it is they're very careful self limiting tactic so. up to now at least they say it's not

only that they have to have been nonviolent but they've been very careful i think to be non-aggressive it's a very contained a very polite form of civil disobedience in that sense so really it the 2 i think should be seen as a kind of complementary intervention in public life in a sense from those involved that we just can't carry on with business as usual and certainly in the u.k. where extinction rebellion began. that the 2 have worked very closely together so so they're not really rivals they're not even really following fundamentally different tactics or strategies to talking to thank you for joining us professor brian dosen from university thank you. now to iraq where official site least 15 people have been killed in i'm to government protests in baghdad overnight it brings the death toll to more than 100 since violence began last week the country's prime minister has announced reforms

that a hope to quieten the unrest but tensions remain high. country in crisis . the prime minister's efforts to quell the violence had little effect as the death toll rose on sunday. demands for jobs better services and an end to corruption have been met with force demonstrators accused security units of firing on crowds and deploying snipers. the youth are protesting peacefully what do they want from us why are they killing us. officials have responded with mixed messages the prime minister addle abdul mahdi offered to meet with protesters but he also defended the security forces. while iraq's interior ministry pointed the blame elsewhere. live in connecticut

there were no clashes a confrontation between the security forces and the brotherly protesters but there were militias that the victims. sad if it were the prime minister said the families of those killed in the protests will qualify for state benefits he also announced a string of reforms including an increase in welfare unemployment benefits and to create new jobs officials have asked the protesters for time to implement the changes but gaining their trust will be a challenge. this is the news life from but it still to come the world athletics championships separate from the heat on attendances as it wraps up. through the final match and it's. also the nobel prize for medicine has been awarded jointly to 3 scientists from the united states to great britain they were chosen for their pioneering discoveries of the way cells sense

and adaptive oxygen. it's the 1st prize announced by the nobel committee this year . converting food to energy is a process that wouldn't be possible without oxygen but oxygen levels can fluctuate dramatically in the body. during exercise climbing to high elevations or pregnancy amounts of the vital gas that are available for metabolism vary. to keep functioning the body cells have to be able to adapt to these changing levels of oxygen but how does this adaptive process work william kalen serpico radcliffe and greg samantha discovered the mechanism behind it when i would say the benefit is understanding this fundamental mechanism for the practical applications are all yet to come and that's actually what's the tries to great discovery that it opens up so many possibilities i mean it creates new new research areas for example

in the healing of wounds treating patients with severe anemia or even cancer in their discovery kalen ratcliffe and cements and have laid the groundwork for a new era of drug development one that's now starting to address many dangerous ailments that modern medicine seeks to heal. now let's get more on this from a derek williams from a d. w. science welcome a derrick from the report they have a stiff does sound very interesting tell us more about what caitlin radcliffe and samantha have done well these 3 researchers back in the 1990 s. looked at that 1st of all oxygen is fundamental to life everybody knows that we need oxygen in order as we just heard to convert food into energy and every organism needs energy so we've known that for a very very long time in fact an earlier nobel prize laureates received it in the thirty's for describing that process of oxygen helps turn food into energy what we

didn't know is how cells respond to the availability of oxygen because oxygen is available at different levels all the time depending on whether for example you're exercising or if you're sleeping your cells receive different levels of oxygen all the time so these fundamental processes of how the cell knows what it needs to do at a particular time because it has a certain amount of oxygen available that was very complicated and these 3 researchers figured out the processes at a genetic level that are actually ongoing in the cell that determine that and we are out of there is what we have to think of the quote was the a new level a new a different way of drug. procedure so it took us or some of the project a lot of patients and why is this a revolution as as we as we know it has oxygen involves everything from wound healing to that there are many many different aspects of metabolism that the oxygen affects and the availability of oxygen affects one concrete example for instance

which is going on now in drug development is and is in the area of cancer research that was touched on the in the report as well which is tumors are able to kind of hijack the oxygen availability systems within the body and force the body to grow blood vessels to provide them with the nutrients and the oxygen that they need now the drug companies are for example looking with based on this information they're looking at ways to blow. that at least locally within tumors and effectively then strangle the tumors or cut off their oxygen supply so that's one approach that this fundamental basic research actually is is helping to support ok so we are just entering the season now i think tomorrow it's the prize for physics to be announced who are you tipping. the nobel prizes are notoriously difficult to really predict i think i've got to write in the last 15 years but in physics they generally tend to bounce back and forth between very highly theoretical and physics questions that

have more of a practical. aspect last year the scientists we see that for sort of these tools made of light that you could use to manipulate molecules of molecular level something practical i would guess that it's probably going to be something theoretical this time around and we've been doing lots of reporting this year we've been here a couple of times talking about exoplanets i think it might have something to do with that so that but don't hold me to it twice in 15 years we'll find out tomorrow for another religion date of you science thank you. the nobel prizes for peace and for literature will also be understood this week. sport now the world athletics championships in fatah have come to a close every 2 years the top athletes of track and field take center stage at the u.s. dominated the final day of the global event but didn't manage to fill the seats. 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 man like me humble would be odds world championship gold to last year's european title was in the javelin understand peters won just the 2nd ever world gold for granada above on the track kenya's timothy cheerio it produced a blistering performance in the 1500 meters hitting the front from the opening lot and never letting go of the lead was just too a chap to guy won a thrilling last lap battle to take gold for uganda in a tense those meters. the sprints belongs to the united states a leader led an american one to 100 metres hurdles i. didn't really go to her success in the individual hurdles event as the u.s. women destroyed the field in the 4 by 400 meters was and the
