he's still commander in chief and direct security forces. >> translation: i'm scared al qaeda and the islamic state group might try to make use of the current tension on the pretext of defending me or others. therefore you must carefully check whether all convoys and armed men are law enforcement or not, there are those that will take advantage, saying the country has entered a crisis, and it will be their chance to loot and steal. be aware of those trying to do bad things. >> while maliki and his supporters maintain the job is his to keep. iraqi political leaders have moved on. >> sunnis are welcoming the nomination that the deputy parliamentary speaker. it's a chance to put the country back together. >> in kurdistan, all of us, we did whatever we could to build iraq based on federalism,

barack obama decided to send them. 70 more, and their job would be to assess what has been done, the damage done to the islamic state group, the group that, of course, has beseemed the kurdistan and the minorities around kurdistan as well. after the series of air strike announced last week behind me at the white house, now the task is to go in and see just how much damage has been done by the - to the islamic state, and continuing to assess the iraqi forces and the peshmerga force, the kurdish forces that are, in fact, battling the islamic insurgence. >> mike viqueira in washington. the peshmerga was knocked on its heals and had to surrender towns. kurdish forces retook the territory once the u.s. regained air gain. we go to a town mok more, taken

back by the fighters >> reporter: kurdish forces retook this area, with the help of u.s. military. the u.s. military helped to force the islamic state fighters to pull back, and to retreat to mosul. we are now in the center of mack more up to. as you see behind me, scars of the battle. it's difficult, really, for kurdish forces to hold the line. they are sharing a 1,000km stretch of territory, with the islamic state group. now the islamic state fighters are pushed out of the town. wherever you go, you barely see civilians, people are leaving, packing their belongings, saying they don't feel comfortable. we know that kurdish forces cannot protect the town. people are afraid. they are coordinating with commanders on the ground, but they appealed for weapons for

the kurdish forces. the peshmerga says the u.s. military is providing ammunition. it's not enough. you'll need heavy weaponry to confront the islamic state group. it was able to capture a lot of weapons from the iraqi army last june, u.s.-made weapons. >> the situation in iraq dominated secretary of state's meetings in australia. there are concerns about foreign fighters working for the islamic state group, and returning home to cause trouble. >> this image caused outrage, a young boy, the son of an australian fighting in syria, holding up the severed head of a decapitated soldier. in sydney t, the secretary of state said... >> this unscores the degree to which i.s.i.s. is so far beyond the pale that any standard by which we judge ooep terrorist

poups -- even terrorist groups. john kerry was echoing thoughts of the australian prime minister and religious leaders. >> don't forget you are muslim. your actions are non-islamic. don't pretend you are a good father, you are a despicable person. >> reporter: the australian government says it is pushing a react of laws targeted at those going to fight. proposed is the cancellation of passports. the assumes that they do so to fight, unless doing otherwise, and the collection and retention of everyone's internet and phone activity records for police to access. john kerry said after the sydney talks that the u.s. and australia agreed a joined up approach to be pursued at the united nations. australia committed planes to help with the humanitarian

component of the united states effort in northern iraq. the defense minister would not rule out helping militarily. both leaders were at pains to stress a threat from the islamic state is not just to those in the middle east. foreign fighters could bring it home too. as the ceasefire in gaza held for a second day, people in the area are doing what they can to piece their lives back together. this as negotiators held indirect talks in cairo aimed at ending five weeks of fighting in the region. we have the latest from jerusalem. >> the two sides are negotiating in cairo, both sides are dug in, not necessarily close to an agreement, but they both want to make an agreement. that will lead them to stay in cairo and extend the 72 hour ceasefire. the focus is on four things, the most important is the rafah border crossing. between gaza and egypt.

a lifelong for so long until it was closed a year and a half ago. a real talk and focus by hamas on reopening the border crossing. the other border crossing is on the table. hamas pushing for construction materials to rebuild israel. very reticent for that, some of the construction material has been used to build tunnels from gaza into israel. also discussed, expanding the ability of fisher meb to fish from three nautical miles off the coast to six. that's part of the israeli blockade, and number four, exchanging prisoners, who have been kidnapped or imprisoned with the remains of an israeli soldier killed in gaza at the beginning of the conflict. as it goes in cairo, what is happening is the people trying to grab life, trying to have normalcy. we saw people filling the markets, and people returning to their damaged homes.

100,000 people have either lost their homes or have severely damaged homes, so the reconstruction process has not begun, but will be massive. the humanitarian crisis is massive. the world food program distributed food and water. 730,000 gazans need food assistance. that is nearly one in two of all of gaza. as the diplomacy continues and the two sides try to get to a ceasefire, the needs of the people of gaza remain high. the palestinian foreign minister is on a tour of latin america, trying to shore up support. he seems to find it. five latin american nations recalled ambassadors to israel and people are taking to the streets to show solidarity with the people of gaza. >> reporter: from mexico to patta gownia, latin america is closing ranks in solidarity with

gaza. chile, home to a large palestinian community outside the middle east, the ambassador has been recalled. ecuador, and brazil have done the same. >> translation: it is because to us the number of children, women and elderly killed seems to us disproportional. >> other leftist governments go furthers, accusing israel of genocide. >> but it's not just political support. here in venezuelan, a nationwide campaign to help gaza yielded 250 tonnes of food, medicine and clothing. these children are making toys for their palestinian counterpart, as venezuela perhaps to become the first country in the next few weeks to receive an undetermined number of orphans and children from gaza. >> they offered to open a

special clinics and homes for the kids, the ones that have lost their arms, their legs to, you though receive the treatment, to receive the parts that they are missing. to do the therapy, and to return them to palestine. >> latin america has a large and influential arab community. lebanese, syrian and palestinians, who live in harmony with the local jewish community. latin america is the region it took the firmer stance in response to the israeli offensive in gaza. before that, almost all of central and south america decided to recognise palestinian statehood and establish full diplomatic relations, angry at israel and the united states. >> and while they are far from the conflict in the middle east, ordinary latin americans and the government are sending the

message that gaza is not far away enough to be ignored. >> another round of protests in a st. louis suburb where a police officer shod and killed an un -- shot and killed an unarmed black teen. it happened in ferguson, outside of st. louis. police urged protesters to home. diane eastabrook is in clayton, a few miles from where michael was killed. what's the latest? >> people have been protesting outside the justice center, and a small protest is going on now. they are demanding answers in the shooting of michael brown. >> anger is spreading in eastern missouri over michael brown's death. [ chanting ] >> reporter: in clayton

downtown st. louis demanding the officer's name and just for the plain teen. >> sharpton wanted an end to violence and rioting. >> no one has the right to take their child's name and drag it through the mud because you are angry. don't be so angry that you distort the image of who his mother and father told us he was. don't be a traitor to michael brown. >> and like sharpton, police here in st. louis county are calling for calm as they have been or the last three or four days, but are prepared for violence. >> all right, a meeting, i understand, with bill ferguson, with some community leaders, the local nw n.c.a. chapter, was there an advance or anything scheduled for later today. >> yes, there's going to be another public meeting similar

to the one we attended last night, in downtown st. louis, bringing people together and trying to come up with solutions. these are come repliated and may not come that quickly. >> diane eastabrook in clayton. more rain in te tried, a day after thunder storms -- detroit, a day after thunder storms dumped a lot of rain, causing flooding. it's the heaviest rain fall seen in decades. bisi onile-ere joins us from warren, outside of detroit. describe the scope where you are right now? >> tony, any other day the freeway below me would be packed with traffic, because we are at the height of rush hour. the only vehicles you see are the ones stranded by the drivers, after they were trying to fellow rising floodwaters. this may not be over.

we had to set up a live shot under an overpass because it started to rain a short time ago. six inches of water drenched the metro area. thousands of homes were damaged. major free ways had to close because of rising water. the water was so high at one point michigan state police had to send in divers to look for submerged cars and trucks. as it stands, we know that there's one death, one woman submerged in water, in her vehicle, and apparently she had a heart attack. >> michigan governor rick schneider urged residents to stay off the roads if at all possible. take a listen. >> there's significant damage on a number of freeways, in terms of flooding. we made a significant survey of the areas. i-79 and 636 is in serious

challenge. south field freeway between ford road and i-94 - a number of spots. we are encouraging people to stick to essential travel, and think about being safe. >> reporter: and there are a lot of freeways like the one here below me that will remain closed. crews are sent in to make sure that oil slicks are cleared away for the time that they do open the roads, that they'll be safe, and some have blamed the widespread flooding on the region's sewer system, some saying that the sewer system is in need of repairs. we are talking about $30 billion. >> infrastructure again. so bisi onile-ere, any estimates on how much damage the flooding has caused? >> no word on any crisis just yet. i can tell you from looking out here in the communities, on the roads, there are so many cars out here that were left.

people had no choice. it was their life or their vehicle. they chose their life. at this point we'll see a lot of home damage, property damage, a lot of flooded basements and vehicles left stranded and damaged. >> appreciated. >> bisi onile-ere in warren, michigan. >> coming up. more than 1,000 dead from ebola, and the virus spreading. now making experimental drugs available. when you run a business, you can't settle for slow.

there are caveats. ethical criteria must guide the provision of intervention. these include transparency about all aspects of care, in full concept. freedom of choice, confidentiality. respectful person and preservation of dignity, and with the involvement of the community. >> zmapp reportedly showed promising results at a u.s. hospital, treating two missionaries infected with the virus whilst working in africa. the manufacturers say all the available supplies have been sent to west africa. liberia says it will treat two infected doctors. the first africans to receive the treatment. the epidemic in one of the world's poorest renal jornings where health -- regions where health care regions are unable to cope, opened an ethical debate, including who should

good to talk to you. n.a.t.o. said on monday there was a high probability that russia could launch an invasion of ukraine. defense secretary hagel believes russia could invade you grain. let's put it on a percentage, 100% being a russian invasion, what is the likelihood of a russian invasion of ukraine - come on, help me here. >> you are putting me on the spot. >> i am. >> if n.a.t.o. is saying high probability, you know they are watching this like a hawk. this is what they are about. they were formed to deal with the soviet threat. you have to think it's 70% or higher if they say higher probability. >> 70%. so if that is the probability, why? we come back to the question of why. do you have a good explanation as to why vladimir putin might do this? >> i have no explanation for why

vladimir putin will do this. let me tell you why i feel that way. listen, vladimir putin took crimea. what he did was he took a million pro-russian voters out of the ukraine. if he invades eastern ukraine and takes a piece of ukraine, he'll take another giant chunk of pro-russian voters out the ukranian system. that will leave a really angry anti-russian ukraine that is going to want to join nato and the e.u., what he was trying to prevent. i don't think he'll march to kiev, or fight a bunch of people that won't want russian trips there. i think strategically there's a question mark. he seems to be doing this a day at a time. >> as you know, european commission president barroso warned vladimir putin in a telephone call against military actions in ukraine under any

pretext, including humanitarian. would such a warning mean anything to vladimir putin at this point? >> i don't think so. he's taken crimea so there is an imbalance here, and that is russia considers ukraine a vital interest, you know, a state on its border that has been a buffer. it cars about ukraine. we don't really care about ukraine as much as russia, we are not willing to pay big costs or start a big world war with russian agent, a regional war over ukraine, which is small potatos. >> what is n.a.t.o. willing to do, the u.s. willing to do, if 70 becomes 80 becomes 100 and russian forces move in to ukraine. what is the u.s. willing to do about that? >> if russia were to move into eastern ukraine. they invaded georgia, remember, and took a bit of georgia. if that's the playbook, i don't

think n.a.t.o. will intervene, they don't want this to yef callate into a russia, nato, nuclear weapons conflict. if vladimir putin invades eastern ukraine and pushes on towards kiev, pushes on towards the western ukraine, that begins to change the calculation. at this point n.a.t.o. has to treat this as a threat. we are in an area of uncertainty and unpredict ability. >> jim walsh is a research consultant. thank you. >> thank you. . >> human rights watch is accusing egypt of the worst massacre in the country's modern history the advocacy group released a report saying that protesters had been killed and july and august. roxanne joins us with more.

>> see you back. in uganda the president is urging lawmakers to not rush to reintroduce a controversial antigay law. the controversial court threw out the law. the president met members of parliament and asked them to consider the economic consequences of passing the bill again. the antigay law imposed harsh penalties for homosexuality. the u.s. world bank suspended aid to uganda. in libya gunmen killed tripoli's police chief as violence between rival militias derailed attempts at progress. it comes hours after parliament decided to open the next presidential election to the public. lawmakers have been heating in tob ruck for weeks because of fighting in the capital. the government is trying to stop militias from overthrowing and using violence. >> in venezuela and columbia closed their border to crack

down on food, gas and other goods. smugglers sneaked the items into columbia. for venezuela, the smuggling creates shortages, we have the story from the venezuela-columbian border. >> this is an important bridge separating columbia from venezuela, it would be crowded with people, car traffic and trucks. this is the first night of the closing of the bridge and the border between columbia and venezuelan. the venezuelan government in particular is trying with these clothing to reduce the smuggling of basic goods and gasoline from venezuela to columbia. that the government of venezuela considers to be responsible for the shortages that have been affecting the country. >> i agree with the closing. hopefully in this way we can

find food. the people take it away. we can't find a think. >> 40% of goods are smuggled in to columbia. most of the people we talked to are saying that this measure will probably not do much. >> translation: i don't think it will do much. contraband has always been here. >> a lot of people don't seem to be aware of the new measure, and have told us that we'll have to spend a night here waiting for the bridge to reopen, or they may try to get in illegally, crossing the river. this is an experiment for now that will go on for 30 days, and we'll see if it will be able to reduce the amount of smuggling between the two countries. >> so an annes thesiologist said an ohio inmate suffered during his ex-execution.

we have this and other news. >> a doctor working for an ohio ipp mate executed in joint enterprise said the prisoner experienced pain and suffering before losing consciousness. in a report released it was said that the execution was not humin. neither of the drugs used could be relied on to produce rapid loss of consciousness and death. the man's children filed a law sued contending he felled needless pain. if chelsea manning doesn't receive hormone therapy, they will sue. it was approved by deputy secretary chuck hagel. the aclu and manning's attorney said she has not seen the treatment. manning changed her name to chelsea and is serving 35 years behind bars for giving wikipedia classified documents. in california, a drought bond deal has been reached.

officers. he said he danced the most. >> he has it right. that spin needs a lit the work, but the thinking behind it. he has it right. >> it's the effort. >> he has the right. thank you. coming up, they like eped it to a jelly doug nut. it mimics brain tissue. the closest scientists have got to mimicking brain function in a lab, and it could be a brain changer - next.

he sought treatment for depression, a toxicology report will take two weeks. those that develop post-traumatic stress disorder have twice the risk of dying early compared to vets not suffering p.t.s.d. they have a greater risk of heart and chronic disease, according to findings from a study analysing more than 2,000 vietnam vets. at the same time for troops that served in iraq and afghanistan, and made it home, as many as a third are battling p.t.s.d. randall pinkston reports on how a new virtual reality treatment is helping them. >> army lieutenant john o'brien served four tours in iraq, in special operations. he had many close calls. >> i got my purple heart for a rocket attack. i wept head-first into a wall. i had 8 discs in my lower neck and back, and conditioned to drive on. -- continued to drive on. >> reporter: it was the injury

invisible to the naked eye doing the damage. >> the death, kahnage, violence - you get immersed in it and it creates sadness. you want it to end. >> in 2004, between tours of duty, o'brien went to a private psychiatrist. the diagnose post-traumatic stress disorder. o'brien paid cash and paid no one about his illness. >> it's like a dirty secret. the stigma attached to p.t.s.d. is so severe, especially in a male-dominated macho environment like the army, you don't want to show a sign of weakness. >> he went back to iraq, the fire fights, the attacks, the carnage. >> when i was there i was fine. you have to get your job done, you have to stay alive. it's when you come back, the adrenaline stops. everything is calm. that's when bouts of anger, for

no apparent reason. bout of depression and crying. >> he didn't get treatment until he got in a fight with a taxi driver and ended up handcuffed in the back of a police car. >> i thought i was in iraq, and i thought i was captured. i was trying to reach for my weapon. >> but in reality you were in a new york city police car. >> that's what made it frightening. >> o'brien's psychiatrist recommended a treatment center. >> when you have post-traumatic stress disorder, your nervous system is in a state of hyper arousal, you are ready for something bad to happen again. hearing a car backfire on a city street might startle you and think you are back in iraq or afghanistan. there's something that we consider relatively neutral has become a queue or trigger of fear. >> to counter this reaction. the doctor and her team use reality exposure therapy.

a computer replays a patient's trauma. i tried it to see how it works. >> here on patrol, have you a bad feel. your hair is standing up on the back of your neck. all of a sudden what happiness is a car bomb goes off. there you go. >> my. yes. >> you go over and over it as if it happened again. >> for nine weeks this experience is combined with therapy and a drug helping to spood up a learning progress, all to help patients like o'brien reset the brain chemistry. >> we have the memory, but the site of a car will not trigger a panic attack or symptoms of arousal the way they did when deployed. >> with this treatment here, much more calm. my anxiousy is down, panic attacks. i don't have flashbacks any more. i'm comfortable with myself. >> o'brien hopes his story

inspires other members of the military to get the medical care that helped him find some peace. bioengineers at tufts university managed to create the most realistic fake brain ever. until now brain models have been able to look like a brain. this breakthrough could help us better understand the mechanics of the brain. jacob ward is in san francisco for us. good to see you. i know the study is important. i need you to tell me why. >> basically, tony, it's been hard up until now to study the brain and scientists at tuft university created what looks like a tiny donut made out a spider-like silk and a gel and took rat neurons, cells from rat brains and grow them across the center of the doug nut, creating a microcosm of hour our brains look, a 6-layered tissue like

material. what is useful, is until now one you study the post-traumatic stress disorder, that soldiers suffer from iuds and the conclusive effects in football, you study people after they died. in this case the scientists studied the impact on this little dough ut, this squishy bit of fake grey matter and come away with a good sense of how the brain behaves. >> if scientists are able to build a model of the brain in this way, what could they do with it? >> the researchers are existed about the concept. now they have a lego like building block, once they build it no a functional brain, could implant a prosthetic. there has been a lot of promise in treating parkin sons. others could go in there, you

could know how the brain will respond. it is a good way to model the circuitry of the brain, knowing how the drug moves through the brain, something we cannot observe unless the person is dead and you dissected the brain. the idea you could have a living model, living for as long as in my opinion weeks in the lab means you can do amazing experiments on it. >> that sounds exciting. jacob ward in san francisco. it's a done deal, the l.a. clippers have been sold. former microsoft chief steve balmer is now the new opener. the n.b.a. board of governors approved the sale. donald sterling tried to block the deal put together by his wix. donald sterling was forced out of the n.b.a. after making racist statements. coming up on al jazeera america, a poster causing controversy. it's mapt to deter -- meant to deter alcohol abuse.
