those cookies forces are still very much in control of vast areas within that proposed safety zone so again it shows you the kind of problems that that the turks could be up against the americans could be up against the russians could be up against in trying to make sure that we don't see a sudden escalation again in violence charles thank you charles stratford joining us live there from china on the turkey syria border where democratic members of the u.s. congress are criticizing president trump's decision to remove sanctions on turkey that's in exchange for this temporary cease fire they're promising to push through new sanctions on taking next week even as trump is celebrating the fragile truce our white house correspondent kimberly help it has more from dallas. at a texas rally before thousands of supporters u.s. president donald trump celebrated the cease fire the white house has negotiated with turkey by his own admission he calls his strategy unconventional you without

really a drop of american blood no one drop of americans want you or we've all agreed on a horse or a ceasefire in the border region of syria. i do was unconventional what i did i said they don't have to fight a little while sometimes you have to let them fight a little while then people find out how tough the fighting is. but outside the rally members of the kurdish american diaspora protested the agreement . we don't have much faith in the ceasefire since you asked kurds to push 20 miles away from the border and that's where the majority of the kurdish incursion areas are so it's given turkey everything that they're already asking for so what kind of a ceasefire is it if you ask one side to give up everything in washington congressional democrats are also criticizing the white house decision to remove

recent turkey sanctions so congress is promising its own bipartisan sanctions against turkey in the coming days senate republicans say the agreement abandons kurdish fighters allied with the united states what we have done to the kurds will stand as a blood stain in the annals of american history. trump supporters in texas are backing trump's withdrawal of u.s. soldiers from northeast syria they say u.s. lives have been at risk for too long i think we would have left him there they could have been involved in between september firefight between turkey and the kurds i think it's time that we got out of the enormous wars over there and let them deal with their own war. we've taken out very few men that were there and brought them home but we still have a lot of our young men over there so i think the. government was going to do that anyway i don't think those few troops that came out to cause the problem president

trump says the next 5 days of the ceasefire will be critical but he's optimistic he says president arab one is a gentleman who just needed some tough love to reach an agreement trump is promising to host erda one at the white house next month kimberley health at al-jazeera dallas texas at least 30 people have died and dozens more injured following an explosion in eastern afghanistan a mortar round he's a mosque in hostile minya district in non-god for evans's worshipers gathered for friday prayer is the roof of the mosque collapsed following that blast inspiring thousands of protesters are marching towards bus alone from all over the catalonia region as part of their campaign for independence unions have called for a general strike on friday or the jailing of 9 catalog separatist leaders the sentences for their roles in catalonia is filed push for independence 2 years ago has sparked days of violent protests. government demonstrations are underway in

negligent and led to this and then the next day they come and leave these taxes on them so it was it's not just this accumulation of things then and also we have to look back at the prime minister a couple of weeks ago having a big controversy with spending $16000000.00 on a subway. model while he fired all his staff at his television station and he's not paying their salaries so it is a series of events that culminated with the new taxes that came into place. still ahead on al-jazeera as the u.s. imposes new tower suck your thing which we ask is the white house opening a new front line in the try to.

a broad showdown in parliament on saturday that's after clinching a last minute agreement with the european union but bars johnson doesn't know if he has enough votes to get the deal passed by parliament many m.p.'s his deal is worse than the one they've already rejected 3 times the latest agreement avoids the need for a hot border in ireland and allows all of the u.k. to leave the e.u. is customs union. the white house has acknowledged that president trump build up military crane partly to push key is to hold investigations in connection with the 2016 presidential campaign but acting chief of stuff mick mulvaney soon backtracked on his statement and donald trump's lawyer distanced the president from the remarks democrats say this is further evidence of wrongdoing bolstering the case for impeachment castro has more from washington d.c. . the white house has a message for anyone who criticizes using american aid as leverage over

a foreign nation get over it there's going to be a political influence in foreign policy by the white house chief of staff offered no apologies for the july phone call between president trump and the leader of ukraine in which trump pressed for ukrainian investigation into claims that a hacked computer server that played a role in russia's 2016 election meddling campaign had been moved to ukraine trump was withholding u.s. military assistance to ukraine when he made the request that he also mentioned to me in past that the corruption related to the d.n.c. server absolutely no question about that but that's it that's why we held up the money now there was a reported demand for an investigation into the democrats was part of the reason that he was on the to withhold funding to brady the look back to what happened in 2016 certainly was was part of the thing that he was worried about in corruption with that nation and that is absolutely appropriate for the justice department has been examining the origins of the russian vest

a geisha in which the president calls a hoax but in the july phone call with ukraine trump also asks for an investigation into his political rival joe biden the white house claims that part of the call had nothing to do with withholding aid. meanwhile gordon sunland the u.s. ambassador to the e.u. gate closed door testimony before congress on thursday sunland were. central in trump's efforts to pressure ukraine to open the investigations but said he was unaware the president was after dirt on biden in his prepared remarks sun testifies inviting a foreign government to undertake investigations for the purpose of influencing an upcoming us election would be wrong with holding foreign aid in order to pressure a foreign government to take such steps would be wrong i did not and would not ever participate in such undertakings still more witnesses are scheduled to speak with congressional investigators in the coming days as democrats charge forward with

their quest to kill back this onion of the trump administration's dealings with ukraine the house will likely vote on an impeachment before the end of november with the senate preparing to put the president on trial i do joe castro al-jazeera washington well later on thursday mulvaney did try to backtrack on his comments in a written statement to journalists he said there was absolutely no quid pro quo between ukrainian military i'd add any investigation into the 26 day election well the democratic chairman of the house intelligence committee adam schiff has responded to by these comments things have just gone from very very bad to much much worse. the idea that vital military assistance would be withheld for such a patently political reason for the reason of serving the president's re-election campaign. is. a phenomenal breach of the

president's duty to defend our national security and i hope that every member democrat and republican will speak out and condemn this illicit action by the president and his chief of staff. u.s. energy secretary rick perry has announced his resignation just as he faces questions from the impeachment inquiry into president trump he has been ordered to provide documents related to a ukrainian state energy company as well as explained his part in a call between trump and ukraine's president the former texas governor has been in the role since march 27th seen trump said perry quote has done a fantastic job but it was time for him to leave. new u.s. tariffs affecting 7 and a half $1000000000.00 worth of european products have just come into effect it's in response to what washington calls illegal use subsidies for aircraft manufacturers

but the repercussions of. history including inspire thousands of families depend on all of oil exports for the livelihoods. harvest time in spain should be a time for celebration all of this year it's a time of anxiety as they shake down the trees the u.s. is imposing a new 25 percent import tax on that tax that could decimate this 5th generation family business unable to compete with cheap imports. getting into. the vessels that are carrying spanish all of oil to the states haven't even reached their destination so what's going to happen they were sold before these tariffs were a threat so pushing a 25 percent margin on top of this will kill our competitiveness. spain is the world's largest producer of all of oil exports to the us a worth $440000000.00 but those working in the fields have not had

a easy lately last year's record harvest all of oil's purchase price to plummet by 34 percent and more and more countries are planting their own other things joining them are. piling the tariffs on top of this could lead to collapse. i am nost wheat thousands of out of workers took to the streets of madrid demanding the e.u. push back on the new terrace and prop up the industry and say they don't understand why an agreement the politicians had with should penalize their products. we think it's very unfair because the agricultural sector acts like a monetary exchange for other industries that have nothing to do with the sector in this case it's the aeronautical industry which has. nothing to do with us but all the producers are already feeling the squeeze around $845000000.00 worth of spain's agricultural exports will face u.s. tariffs the e.u. warns it will retaliate with its own import taxes if they win that parallel case

a delegation proposed to us a 5 day deadline we have valuated it and reached an agreement according to the agreement the united states will make sure that the kurdish rebels will leave outside of the safe zone within 120 hours which is 5 days we have paused our operations for 120 hours the rebel groups will have to destroy arms leave defensive positions and go outside of the 30 kilometer zone within this timeframe after these terms are met the turkish operation will end its all strike that has more from jenin on the turkey syria border to all intents and purposes certainly according to what we've seen and heard the cease fire does seem to be holding here when we arrived early this morning early this morning sorry there was the sound of gunfire and what we understood could well be light artillery that was among some news

organizations some. being reported as an indication that the cease fire in fact had been broken but certainly according to the free syrian army fighters the syrian rebels that we've spoken to they say that the situation is calm we understand that that smoke you can see behind me is some sort of fire is not necessarily to do with any kind of violation of the cease fire. at least 30 people have died and dozens more injured following an explosion in eastern afghanistan a mortar round here to mosque in a housecoat mania district in one province as worshipers gathered for friday prayers the roof of the bosc collapsed following the blast thousands of protesters are marching towards barcelona from all over the catalonia region as part of their campaign for independence unions have called for a general strike over the jailing of 9 cattle and separatist leaders. the headlines the news continues here on al-jazeera after

a techno. this is techno a show about innovations that can change lives the science of fight fire we're going to explore the intersection of hardware and humanity and we're doing it in the unique way. this is a show about science. not by scientists. tonight. techno in search of the great american prairie where in the current state yeah ironically we have such little of it left farming and over development killed it now get ready for this explosion of color and the return of

these native animals how many plant species do you have in here but volunteers trying to bring back one of the planet's most complex ecosystems ran into trouble we just needed something that help to level the playing field why a certain animal from america's past was needed to pull off the impossible we've just arrived at the end that use a grassland and i'm seeing these bison for the 1st time in reach of davison is an environmental biologist tonight a trip to the heartland always a baby. deer a santa maria is a neuroscientist i'm phil tourism i'm an entomologist at big drought of 2015 takes a hidden toll. from above these trees may look green and healthy they're not here we see something that's dramatically different now the technology that can see what we can't that's our team i'm

a prairie fire now let's do some sun it's. hey guys welcome to techno on phil tours joined by kara santa maria maria to davison and so they were going to talk to environmental stories and to start off the great american prairie to me it's one of those iconic images of how the us used to be unfortunately now it's almost entirely just a part of our history yeah there's been a lot of over development of farming and a suburban explosion that's really taken a toll on a lot of prayer ecosystems illinois has been extremely hard hit it's changing but there's been a big change in the landscape there yet this is happening across the united states but i got to say what i really love about this story is that there's a bit of us west so there is i don't want to give anything away so let's go about 90 miles outside of chicago where they're bringing back a little piece of history it's kind of

a big piece of history ok think piece of history to go on. you were looking at a 3500 acre experiment in a growing field in known as restoration ecology. this is the new choose the grasslands preserve in franklin rove illinois 90 miles west of chicago where the nature conservancy is rolling back time 200 years to restore a tall grass prarie that was almost extinct. were in the curry state yeah ironically we have such little of it left at the time of european settlement about 2 thirds of the state some 2025 1000000 acres of the state was tall grass prairie we have less than 1100th of one percent of the native prairie but still intact. the mission is being overseen by 3 illinois and natives

just walk director of science for the nature conservancy project director bill kleiman and restoration ecologist. cody considine. it was a vast landscape dominated by those grasses but the real diversity of the prairie was in the wild flowers in the form of the broadly plants and thousands of species of insects and dozens of birds and mammals and reptiles that called the prairie home along with the animals like the bison. what was once this bass landscape across much of illinois has been virtually eliminated and turned into the corn belt . but illinois isn't alone since the late 1900 prairie grasslands across the united states have been steadily vanishing. i've heard grasslands and general referred to as the unheralded counterparts of the rain forest and grasslands have a critical role in terms of climate change as well in a prairie most of that carbon a stored in the soil and so it's very secure for very long term storage

a soil organic matter in essence the plants of the tall grass prarie absorb carbon dioxide trapping it in their deep roots. the restoration began in 1906 growing from a small plot of remnant prairie land that had never been farmed. and starting with fire the process hasn't changed much in 30 years. it's completely fire dependent without fire we could not have pretty the vegetation grows more vigorously most species of plants have a season of more intense blooming right after you do the 1st year the 2nd year after a fire no one knows that transition better than restoration ecologist cody considine . gray we're standing in what looks to me at least 2 very different types of areas what happened here so yes or right in the line of 2 different prairie restorations

the one right here was planted 2 years ago and the one behind us was planted a 3 years ago and so over seeing is as these prairie restorations get older more plants emerge they get more mature they're flowering so they're quite dynamic how many plant species do you have in here for this particular plane and i believe we had 130 species ranging from there's a native western sunflower this is a conal species we have rattlesnake master here we have grassley of goldenrod here isn't a neck and they show here a paper book on foot already flowered. all those bloomers started here all right so this is the cedar and. project director bill kleiman well you might think that the prairie stude would find its way out into these former corn fields but it doesn't walk very fast so we would have to wait millennia whereas we can collect the seed from the remnant prairie of bring it out to a cornfield that we're retiring planted and it'll grow back year do you have

a sense of how many see you in the volunteers here have planted over the years about $250.00 species a year so it's it's millions and millions of sea. conventional wisdom was to plant 10 pounds of seeds breaker but bill ordered 50 pounds and the fields blossomed none of it would be possible without a core of volunteers like jay stacey. so what are you cutting today this particular for is called per coreopsis scientific name coreopsis paul meta how long have you been doing this i've been doing this is my 21st year. i'm a prairie bar where. all the tall grass planting was a little too successful. we just needed something that help to level the playing field. what they needed was something to thin out the grass.

like an enormous vacuum the solution not a dyson but a herd of bison. a posse of 800 pound grazing machines. we've just arrived to furnish use a grassland and i'm seeing these bison for the 1st time and i feel like i've just been transported back 15200 years it's pretty it's pretty remarkable to see these enormous animals. we're almost wiped out from north america all there's a baby there's a little one 0 a couple of. bison have been part of the vision for the project since the very beginning but it's taken us close to 30 years to be able to put together enough of a landscape where it was a practical consideration for us. these

iconic bison were the missing link for a massive restoration of this endangered tall grass prairie run by the nature conservancy. would you say that they have been a game changing factor here. as these animals are going to make a difference on this prairie. i hitched a ride with misuse of project director bill kleiman and restoration ecologist cody considine to track down the bison in their $500.00 acre grazing area. the wire the bison so important to the restoration process bison 8 grass and they're the disturbances they're creating puts diversity on the landscape as they graze the nutrients are going in one of them is coming out the back and they are getting a very quick nutrient cycling on the prairie. those bison patties are spreading

seeds and fertilizing the soil what's the average weight of a full size bison with a coach can range from 800 to 1100 pounds and the balls as they mature they can get up to 2000 pounds massive so how many bison do we have on them on the reserve 30 adults and 16 calves the calf was just born last week a little tiny want to get easily pick it up it's pretty exciting to think about the calf being born an illinois prairie that hasn't happened for probably 200 years. what happened to bison here there was a tremendous slaughter of bison in the 870880 s. . just walk is the chief scientist for the illinois chapter of the nature conservancy. has estimated by the turn of the 1000s there were probably 402-1000 animals that had persisted out of that massive herd of 30 to 60000000 it's close to

extinction it's absolutely closely extinction there was definitely a market for the hides for the meat also part of it is that it was encouraged by the u.s. government as a strategy to help reduce the food supply for the native americans in the conflict with the native american peoples it's estimated there are about 400000 bison now in north america. but most of those mice and we're bred with cattle for meat production only about $20000.00 are pure american bison. that genetic line dates back to 913 when 14 bison from the bronx zoo were trucked to win cave national park in south dakota at the behest of teddy roosevelt. so when it was time to bring bison to choose they looked for a posse with the wind gave lineage. going. to want to broken grassland another nature conservancy preserve in northwest. when

i was in the october 24th team and brought back 20 animals with us we essentially separated off the animals that we were going to bring back to illinois make sure that they were how to clean bill of health. 7 of the females we strapped g.p.s. collars onto so that we can get near real time movements of the animals tracking those movements with the g.p.s. collars is julian brockman a bison researcher at southern illinois university. what kind of data are you receiving so we're getting location information a g.p.s. point on a map every hour 24 hours a day so can you show me what you've been seeing sure these are the bison locations for yesterday they seem to be spending a lot of time along their corral and trap pressure and i can corroborate that because we were there and we saw them there so what would you say is the ultimate goal of your study having man amount of data really changes how we look at their

movements and their selection it helps to understand what type of habitat they're like for reintroduction in the future. among the 2 dozen scientists doing research at new choose is dr holly jones a conservation biologist at northern illinois university with her team she's traveling in tagging small mammals to assess the impact of the big bison. the completely restoration ecologist playground i get so excited about this field say let's see if i'm one of them and. there it is small mammals are food for aerial predators things like hog things like owls and so it's really important to know how they're doing to be able to say how the person doing as a whole and that's because if the small mammals are tasty enough to become good prey they're feasting on a healthy environment of insects and plants. what do you see since bison have been introduced we've had. 13 lying around the world which was

very surprising the line of evidence is pointing towards a shift in community compositions and there are different plots of land that have been restored at different times and all the way back to 20 years ago we can look at a plot of land like this that was restored 40 years ago and we're going to plot of land over there that was restored 6 years ago and one sees and look at how restoration progresses. through. how we think improves science in the sense that. you can only go there. less than a year since the bisons arrival the environmental impact is subtle some changes to plant growth and small animal populations but the biggest change may be on humans. for a very connected to this herd they still feel like these are their bodies and this is such a cool thing that we've returned this iconic mammal to illinois it's exciting.

i got to say i love when you guys bring stuff back from the field especially from someplace as iconic as tall grass person reading what did you bring us at 1st till you got to stand up ok i'll tell you are about 6 to ok so here is a tall grass from the tall grass player that is some tall grass stalk i mean i was literally swimming in this stuff you know this is amazing this is part of the vegetation we're taught in this is what the bison munch on this is that's exactly what they munch on this is what the bison were brought in to help control the good news. now these are little seed pods they look like musical instruments but they're seed pods of some of the vegetation on the prairie but a nice little ring to like it and this is what they've been using to replant some of the native vegetation and then when this this is the last piece of the puzzle this is a bison ferment. that surprisingly soft yet and. can see there's stuff in there

arrows a lot of stuff in here so you can see really easily how bison would be dispersing you know these these little seed these large sea disperses across the prairie or does even come to shave like a bicycle when i was looking at that footage i was blown away by the color in the prairie the biodiversity the flowering plants and i wonder if a lot of people have that preconceived notion that nothing grows there would if i told you kara that along with tropical rain forests prairie lands and other grasslands are the most biodiverse complex ecosystems in the world would you believe me. i mean i believe you because you are an expert it's right it's it's totally true but it does hold my mind and i thought it was really interesting to learn how important the prairie land is here in america for you know this big plane that change problem that we're all facing these these grasses and these different plants actually act as a kind of a carbon sink don't they they really do the bulk of the plants in the prairie are

not above ground they're underground because that's how they survive fire they actually are a big factor in storing carbon and that really does feed into the very next story read until you guys tag team do a little verify both from this guy and from the ground you know i got to see california forests from an airplane like no other and while you were in your flying laboratory i was on the ground seeing the reality of trees and what's taken him down. this drought is so epic it's so out of the norm that we actually don't have the answer to what can we expect long term california's epic drought. reservoirs are near empty farmers herding and it's forests are flame are under attack by opportunistic coasts so we're seeing tree mortality all over the landscape but in order to understand these changes to forests scientists must 1st assess their health. using field observations and

airplanes we have the most advanced airborne remote sensing package that i know of on earth today for over a decade ecologist greg as never has been monitoring the health of forests around the world in an aircraft called the carnegie airborne observatory techno profiled his work mapping the amazon in a previous episode this time we joined him on his latest effort to map drought plagued california forests in his tricked out door need to 28. in the back of the aircraft are unique sensors designed to take measurements of the forest canopy while the plane flies over it we're flying over about $8000000.00 trees per hour one of these instruments is known as light our this instrument is a laser system that fires 2 lasers out of the bottom of the plane in a pattern that image is the forest canopy over at everett is that we fly over in 3 d. what the instruments do is provide us a very accurate very unique way of understanding the amount of carbon stored

in california's forests if you don't put carbon in forests then it ends up in the atmosphere and that contributes to climate change the plane is also equipped with a pair of spectrometers used to detect the chemical composition of trees it was time for takeoff where we going today today we're heading out pretty close to the oregon border where we have a lot of force that's unknown in terms of its drought stress and with that we were off from the air we could see reservoirs in rivers clearly depleted of water lake shasta reservoir that's right it's a lot of water policy what you see walk approach but the forest canopy actually looks pretty green but they could look like they're pretty good shape of californias forests are drought stressed today by losses about oh so these forests are in trouble back at the lab as there's team got to work analyzing all the data.

that's where tech news phil torres picks up the story say you did a flight with merida these are the results and looking at the cockpit it looked green but here we see something that's to radically different and what you see we see that the forest is varies from what we would consider pretty average conditions in the yellows and blues up there down to areas that looks severely drought stricken in red next we looked at an area where the drought stress was more acute so this is from los padres national forest this is what it looks like when you fly over gray green looks like your typical southern cal forest. this is what it looks like in chemical detail those trees are doing ok but everything else is showing severe drought stress and that's showing here in red now that we have the view from above we decided to head out for a boots on the ground perspective i'm standing here in the middle of los padres national forest and as you could tell from all the dead trees behind me there's

plenty of evidence of the impact of a multi-year drought one of the biggest problems here a bug that attacks water stressed pine trees. and now we're talkin all those a bunch of tom coleman is an entomologist with the u.s. forest service has a lot of dead trees right here yeah this is a nice will active spot of bark beetle. barbadoes kill more trees than any other kind of insect or disease in north america then you just look across the landscape and you see this kind of patchwork of dead trees mortality is quite dramatic this tree here is full of thousands of bark beetles does that mean that all the trees around here are now susceptible right now from what i've seen it's just basically across the entire landscape have you ever seen this but not here in california.

so just 10 minutes where we're looking at the devastation caused by the pine beetles and now we are here and you can see the damage done by forest fires and there's a lot going on here so even though the wildfires actually gone through an area and cause major mortality it will still see bark beetles coming in afterwards scientists studying our forest are concerned about the impacts from drought not just in california but also around the world now what we're starting to worry about is whether these droughts are somehow all interrelated in length at a global scale to suit a lot of force of the world or in trouble droughts putting pressure we don't know exactly how much of the global forest cover is at risk but we were in that process now of finally getting the measurements we need to make those predictions. the scientists that are studying these things they can say here's the problem but their hands are tied they all they can do is wait for the drought to be over for only you know to pass and try to influence management and policy they need to get

back their 5. plants thousands of protesters blocked roads and gather outside government headquarters for a 2nd day. in the catalonia region calling for independence from spain. and i'm leah harding with sports those protests and the catalan region have forced organizers to call off. barcelona and real madrid will have to wait for their anticipated match. president wants is the offensive in northeast syria will resume within minutes if kurdish rebels don't abide by the terms of the cease fire under the deal announced by the u.s. on thursday kurdish fighters were given 5 days to withdraw from the region where

turkey says it wants to enforce what it calls a safe zone now the 5 day truce is largely holding but they have been some unverified and for some sporadic fighting smoke was seen in the border town of russell on friday morning. tuesday. a delegation proposed a 5 day deadline we have valuated it and reached an agreement according to the agreement the united states will make sure that the kurdish rebels will leave outside of the safe zone within 120 hours which is 5 days. we have passed our operations for 120 hours the rebel groups will have to destroy arms leave defensive positions and go outside of the 30 kilometer zone within this timeframe after these terms are met the turkish operation will end. that is standing by from need turkey's border with syria and as you've been reporting charles that cease fire appears to be holding there was some reports went there of some sporadic fire only

about yeah there have been reports throughout the day of sporadic fire certainly when we arrived here this morning there was gunfire of what we thought was a litle artillery being used but as to as to whether that was in fact munitions being destroyed or whether in fact it was his forces celebrating this disagreement who knows but certainly but will the 10s of purposes the cease fire does seem to be holding interest in the president or the one saying that any reports to the contrary were false. we've also spoken to members of the free syrian army these are the syrian rebels that up to surprising in this offensive they say that the areas to the west of here around the town sorry. a town that was taken by the. turkish forces

a few days ago that it's quiet down there as well so yeah the cease fire doesn't seem to be holding as you say president or the one threatening that if there is any kind of violation whatsoever his forces are ready immediately to to resume their offensive and this is only a 120 hour 5 day cease fire a poor in fact and there's a lot of uncertainty in the child but what happens after that because president other one has said very clearly that his troops are not moving they staying where they are where they are and there are still questions about whether the kurdish forces in fact leave the area. there's a whole host of questions that you could ask picking apart this disagreement the 1st of which is. the turks want a 440 kilometer long stretch for the 30 kilometers deep they say they want all kurdish forces out of it within this 5 day period this 120 hour period last night we had the s.d.f. saying that they recognize the agreement but they would only be withdrawing forces

from the areas where they describe as the contact zone they say area behind me russell lying down to tell abi out which is about sort of 80 kilometers west the fact is that yes the f. control huge areas still of this border so it's going to be interesting to see whether in fact they move i think we're going to have to focus a lot of our attention on what also happens if the cease fire does hold what happens in sochi on choose day when we know that president obama will be meeting mr putin we understand that the syrians could well be invited to that meeting as well russia obviously at the moment hasn't made any official statement regarding this agreement we know what russia represents to the assad regime its number one ally we know the kind of friction and competition between the russians and the americans and garnering influence with the turks the end of the day what president or the one wants is he wants what he describes as all the kurdish terrorists to move back to

make way for this safety zone and he's going to be interesting to see how the russians play this. bearing in mind that this agreement this initial agreement for this ceasefire this polls was an agreement that was brokered by the americans charles thank you for that well matthew browser is a former u.s. ambassador to azerbaijan and a former white house official who joins us on skype from istanbul good to see you again matthew president trump of course is congratulating himself over this deal but it's fair to say that it was president earlier one who has got what he wanted out of. 100 percent yes president ever to one has long demanded a 30 kilometer wide safe zone in which turkish troops are in control and the days just immediately prior to president trump fateful phone call with president carter one where president trump agreed to pull u.s. troops out of the turkish army's way both sides are on the verge of of an agreement

but the last sticking points were these 2 points i just mentioned so president everyone got what he needs. i think he's going to. abide by that cease fire because he has no interest in not doing so so the question is will the s.d.f. forces will they really pull back and then will we get beyond a 5 day pause well let me get your assessment on that situation because president only want to said very clearly at the end of this 5 days if those demands are not met he will begin within minutes the offensive once again and your assessment on just where this situation is place right now turkish troops are on the ground why would kurdish forces pull back what will it look like after these 5 guys well what president on said it's actually a rush of rush lee said form of what's actually in the agreement right as i mentioned a moment ago that the pause becomes a permanent cease fire once it is demonstrated to turkey that the yes the it is

gone so the kurdish militia is no longer in that it's a big if only it would be christian. that's the big if so how does that happen the way that would probably happen would depend a lot on russia now reportedly these kurdish militia fighters are being folded into a russian special forces military units on the ground in syria so officially it'll be under russian command now of course splinters of the splinter group may decide they want to roam around on their own but i would guess that the ability to sustain that fight in the form of guerrilla warfare will will be somewhat limited plus the s.t.'s is quite an authoritarian marxist leninist organization so i think their fighters tend to listen to their leaders quite closely and that of course bites all the more crucial this meeting on tuesday between president. and and putin's because russia of course as you just outlined is absolutely key to this on the ground it might be the united states a brokered the deal might be russia or in fact it sees whether it holes yeah that's

absolutely correct and i think that russia will answer key but russia is really coming out as a big geo strategic winner in this whole escapade number one it's troops as we know are now occupying positions that were fake hated by u.s. troops especially among beach i think they're going to stay there so that's the whole western edge of this safe zone president are to one originally wanted russian troops are also east of this existing security zone where the turkish troops are together with syrian forces so russia is bracketing the turkish controlled safe zone and i think has acquired an outsized role a role that again president putin never anticipated russia could achieve when he launched initially launched russian military operations in syria i think draws are always good to have you on the program thank you again thank you so much there. democratic members of the u.s. congress are criticizing president trump's decision to remove sanctions on to in exchange for

a temporary cease fire the promising to push through new sanctions next week even as trump is celebrating this fragile truce that white house correspondent kimberly how could as more from dallas. texas rally before thousands of supporters u.s. president donald trump celebrated the cease fire the white house has negotiated with turkey by his own admission he calls his strategy unconventional without spilling a drop of american blood not one drop of american. who would i was we've all agreed on a pause or a ceasefire in the border region of syria and it was unconventional what i did i said if you have to fight a little while sometimes you have to let him fight a little while then people find out how tough the fighting is. i am but outside the rally members of the kurdish american diaspora protested the agreement

. we don't have much faith in the ceasefire since he asked kurds to push 20 miles away from the border that's where the majority of the kurdish incursion areas are so it's getting turkey everything that they're already asking for so what kind of a ceasefire is it if you ask it one side to give up everything in washington congressional democrats are also criticizing the white house decision to remove recent turkey sanctions so congress is promising its own bipartisan sanctions against turkey in the coming days senate republicans say the agreement abandons kurdish fighters allied with the united states what we have done to the kurds will stand as a blood stain in the annals of american history. trump supporters in texas are backing trump's withdrawal of u.s. soldiers from northeast syria they say u.s. lives have been at risk for too long i think if we would have left him there they

could have been involved in between a firefight between turkey and the kurds i think it's time that we got out of the endless wars over there and let them deal with their own war. we've taken out very few men that were there and brought them home but we still have a lot of our young men over there so i think the. government was going to do that anyway i don't think those few troops that came out to cause the problem president trump says the next 5 days of the ceasefire will be critical but he's optimistic he says president arab one is a gentleman who just needed some tough love to reach an agreement trump is promising to host our $21.00 at the white house next month kimberly healthy at al-jazeera dallas texas going to lebanon now where government demonstrations are underway for the 2nd straight day protesters angry at new tax proposals which.
