>> hello there, welcome to the news hour from our headquarters in doha. coming up in the next 60 minutes. protest on the syrian border as isil inch ever closer. the u.k. condemns' isil o's isil's beheading of a british aid wor worker. and north and south korea agree

to resandstorm for high-level talks. >> so we begin this news hour with developments in syria and the fight against the islamic state in iraq and the levant. syrian border town of kobane where fighting has driven thousands of people away. surrendeaway. kurds angry at the perceived lack of action. in its strongest statement yet the turkish government said it will do whatever it takes to prevent kobane from falling, and protect its troops t. let's go to southeastern turkey. just give us the latest situation on the ground. >> reporter: nick, artillery

fire coming from kobane. just behind me isil fighters trying to push on the town. but this time the syrian kurdish fighters in the town have been telling us that they feel more confident about their abilities to protect. there is a bit of a crowd behind me at the moment bus turkish kurdish mps have been allowed to come in to speak with the syrian fighters. they have come out and told the people waiting here that they feel that after a couple of airstrikes like there were last night that pushed back isil the syrian kurdish fighters are more confident of holding the town. yesterday they were in desperate situation, but today it seems that the mood has risen. >> you have just been at the refugee camp. how are they managing with the

numbers coming through? >> reporter: well, over 160,000 refugees came from kobane when isil advanced closer. they had to be quickly accommodated by the turkish aid agency. they were set up in camps in available paces. there is one camp behind me to my left hand be, and there are others in the city. it's obviously a difficult situation for refugees everywhere. there are more than a million and a half in turkey. turkey never expected to accommodate them this long. they've spent $4 million on feeding, housing, and educating those refugees. turkey would liking to home. but there is no occasion to do that. >> inside iraq peshmerga forces

to the north continue fighting. many have left their villages and they pour into the city of erbil. >> not a very happy celebration for 250 families at this refugee camp in erbil. this man here was telling me that he set up this shop that he released that this is going to be a tournament situation. of course, they don't want to be here for very long, but they come from mosul, and they know they're not going to be able to go back. families are starting to gather here for the big edes meal. they've been cooking. charities have distributed meat earlier on, and they're happy to be able to spend time with the family as is tradition during edes. when isil stormed their towns they had to flee taking very little things with them. they wonder if their homes were there and they wish they could

buy presents for their children and have them wear nice clothes as is tradition during edes, but they're not going to be able to do this. this is looking more and more like a permanent situation for them, unfortunately. >> the u.s.-led offense led against isil, military jets are on their way. but he promised no ground troops will be sent. isil released a video claiming to show the beheading of another foreign hostage. let's cross to paul brennan in london, who has more on this. out rage being expressed across the borders of u.k. >> it would be difficult to exaggerate the wave of revolution over the past few hours since this video emerged of this taxi driver being

beheaded somewhere in the desert there. mr. henning was on a humanitarian admission when he was captured. he was an experienced man. he had been to syria before. so moved was he by the flight of the civilians, that he resolving to back. in returning he was captured in december of last year. the condemnation of isil's action in the beheading of alan henning, left wing, right wing, and muslim leaders who throw their weight behind the campaign to hopefully have alan henning released. they expressed their deep sadness that he wasn't. david cameron said as a man of great peace, kindness and

gentleness. >> alan henning had no ties with syria, only a deep desire to help those in need. the married father of two had traveled there last december as part of a british aid convoy. he even had aid for syria tattooed on his arm. but soon after the convoy crossed the border he was seiz seized. earlier this week his wife made a plea for his release. >> we need him back home. >> anyone in any doubt of this organization can now see how truly repulsive it is and barbaric it is as an organization. and as a country we must do with our allies everything we can to defeat this organization in the region, but also to defeat it at home. we must do everything we can to hunt down the people who are responsible for this.

>> prime minister david cameron will be briefed by diplomats to get a handle to identify the killers of mr. henning and the previous hostages who have been beheaded, and combating them and launching airstrikes on top of their heads. alan henning's story had touched the lives of many people. more than 100 muslim leader had sent a letter to isil calling for his immediate release. the campaign in iraq and syria and the killing of another british officer david haynes povertied a bigger role against the group. there are no british troops on the ground, but the u.k. have been carrying out airstrikes against isil. and in the death of alan henning's death, they said that his blood is on the hands of the u.k. parliament. >> the hearts go out to the british aid worker, who we believe is in that video, and to

the remaining hostages, and to their families. this is, again, yet another just very clear example of the brutality of this group and why the president has articulated, and is moving out in a comprehensive way to degrade and destroy isil. >> alan henning was taken while driving a an ambulance backed with food and water. even in the eyes of isil humanitarian workers are fair game. >> it makes you wonder if anybody is actually carrying out the aid work in syria and iraq? >> well, i mean there are humanitarian missions ongoing, but the operating operations are very difficult and have been for excess of two years now.

the situation on the ground in syria has worsened. you might not know that alan henning was offered the option of handing over the humanitarian supplies that had been collected back here in the u.k. handing them over to the border to local syrian aid workers who would distribute it. it was mr. hennings' choice to cross the border and become involved personally in the distribution of that aid. i don't think it's going to dry up the supply of humanitarian aid. i think there are going to be many, many people, who, as a result of the visions of horror that we have see from syria day in and day out, are going to be willing to donate, but it does make distribution of that aid all the more dependent on brave local people who are going to take the risks where perhaps international workers are unable to separate any more. >> paul, thank you very much, indeed. paul brennan in london. >> the syrian president and his prime minister have attended

edes prayers in damascus. but there has been no let up in the fighting to allow people to mark the occasion. >> in the mosque not far from his presidential palace in damascus, president assad was among the worshipers. it was time of deflection away from the war. >> this aid is not bringing happiness to our children because the waste and it's supporters from arab countries have decided to turn syria into a battlefield. where they want to settle their scores and imprint their own agendas. the hand of betrayal is bombing our people. >> reporter: the military continue to cause destruction. activists say a barrel pull of explosives hit this mosque, and

air force jets hit several targets in the rebel-held town. wounding people. also shelling in the district where many people were injured. for the fourth time millions of syrians are suffering through relentless war. >> coming up, packed with pilgrims at the annual hajj. >> and a mother receives an uterus transplant. >> an >> student protest lead

necessary hong kong have called off talks with the government. their decision following successful on friday night between protesters and locals, the police have arrested 90 people in connection with the clashes. all right, let's take a look at where the protesters actually are. first up there at the popular commercial district where they set up camp. where they have staged sit-ins and are blocking roads. in the mong kok area, there has been some of the worst violence. that's where the successful took place last night. how are things now? >> reporter: well, this time

last night there were battles and the confrontation has given way to verbal confrontation. we've seen lots of heated arguments, lots of finger jabbing and a sense of disarray in the pro-democracy camp. now the students have been making pretty phenomenal accusations against the police today. they've accused the police of ignoring the attacks on them by unidentified groups last night, even suggesting that the police colluded with those attacks, by allowing the gangs to carry out the attacks. the police have denied all that, and they've called a press conference at 4:15 in the morning categorically to refute those allegations. they have made arrests. mong kok is the area where they

control the gambling, and they want to get back to business. there have been attacks linked to the triads because journalists seem to have think fosympathy for the pro- democracy groups. china has sent a warning shot across the bow of those countries saying what is happening in hong kong is an internal affair. it is a democracy issue, and they warn countries not to interfere. but china really wants to sorted out soon. in a few week's time they'll have the apex summit in beijing, and they do not want this going on in their backyard there. >> what is the employee policing

there? >> yes, hong kong has about 30,000 police officers, slightly less than that. the question raised at the media conference this morning about whether the blue line was perhaps being stretched a bit too far. the police commissioner avoided that question, flicked it to one side. at the moment they contain this sort of unrest. the danger would be if the protest crew moved to other areas, that would then pose a challenge to their resources. they are the best trained and the most disciplined police force in asia. >> we can go across town to the main protest site, and what are you seeing there now? >> as a hong konger i'm relieved to say that at the height of the protest in the occupied central

campaign over tuesday and wednesday where thousands of people have gathered peacefully. there aren't as many people as in those days, but they're slowly trickling in. what we've heard so far are student leaders taking to the stage. and people who were at the mong kok protest who had experienced the violence. they have talked about how the government failed them. a legislative council member, a lawyer, also got on stage and said he was proud of hong kongers for gathering together. now many students hearsay that this is pretty much a barometer of whether these protest also go on and how they'll go on. if people can carry on with these peaceful protests and more people support this side of the protest, then their campaign has some hope. >> when you met with the hong kong chief executive, what

did he have to say. >> well, nick, i'm going to refer to my notes. nothing really addressing the protesters. what they're going through and asking for. he said he wants the protesters to stop gathering. he urged the crowd to dispersed. he said that their occupy campaign is disrupting lives and the daily work of citizens and government workers. he also said that dialogue is the only way forward, and they will come to some consensus but have to accept each other's differences. nothing groundbreaking. and nothing that people are taking heart with. >> thank you very much, indeed. reporting there from hong kong. north and south korea have agreed to resume high-level talks in november. three top north korean officials are in the south for the closing ceremony of the asian games. we have this report.

>> reporter: there is always a lot of excitement whenever north korean politician visits south korea. but it's more exciting when the highest level of delegation to arrive in five years. it's led by the number two in the hierarchy. >> even if it's not an opening ceremony but a closing ceremony our director of the military's general political bureau has bureau has come here. it was a sudden visit, so i would like to express gratitude for the welcome. >> that conciliatory tone is providing some hope in recent years. harsh words and rocket tests by the north korean government has strained ties between the leaders kim jung-un has been

absent from public few for a month, but still, the general is seen as powerful. >> this is as powerful as it gets without kim jong-un here. one of the three had been purged, but the fact he's there, and you get the sense that maybe there is more unity behind the scenes than some of the conspiracy theorists have been expressing for the month. >> reporter: we've seen the hand shakes before. the question is what next. al jazeera. >> the world's longest reigning monarch has been readmitted to a ban bangkok hospital. in somalia government forces supported by africa union troops

have stepped up their fight against armed groups of al-shabab. the groups have suffered significant losses in the south. al-shabab has lost control of its tax collection hub. now somalia and african union forces are making a final push for the time bit of land controlled by al-shabab. we have reports from mogadishu. >> the last 200 kilometers. these soldiers belong to the african mission somalia. the village had been controlled by al-shabab fighters, but the sna captured it without a fight.

>> this is a dutiful operation. >> the african union commander in mogadishu tells me that the soldiers are within striking distance of the port city. if al-shabab lays stronghold and it's form is imminent. >> we know that al-shabab will continue to conduct guerrilla warfare. what we're doing is to to be able to face this kind of pa warfare. >> al-shabab still controls most of the countryside and major roads in south and central

somalia. the aim of operation in indian ocean is to cut off supply routes that the group uses to bring in fighters, weapons. the money made from selling charcoal helps pay for weapons. >> the question is whether they need thos because they ceased to exist as a rebel group a long time ago. >> african unions say al-shabab has been significantly weakened. it does not have the numbers or strength to advance the forces. it's leaders was recently killed and it's replacement is still new to his role. still many people hearsay that al-shabab cannot be written off just yet.

>> let's move ton weather, and typhoon on japan's door step. >> what a nasty feature that has to be said. the system is moving north, moving north, and then it's swept along by the upper level flow. how far north will it get before it's swept along. that's the difficulty over the last few days. it's a powerful beast. 215 sustained winds. it's the rainfall that is going to be the main issue. over subsequent runs, it will drift further north and right over the central part of honshu. now a couple of things that spring to mind, first of all is

where we've had the eruption there. we could see vast ash and mudslides developing there. we've got the gran grand prix, and that is sounds likely to experience some heavy rain as the race goes on. maybe not the heaviest of the rain because that will come up later in the day but they're looking at the situation to get through monday right across tokyo. the system does move away, and then it will begin to quiet do down. >> there have are been tests in nictests in nicker nicaragua over a fishing canal. the chinese company is due to start building in december. many protesters carried banners are anti-china slowing began

slogans. the police have been asked to find students who vanished last week. they have called for a federal investigation. from mexico city we have more. >> reporter: it took more than a week of pleading and begging by these desperate parents before officials from the federal government would see them. but the government could no longer ignore their anguish. >> he need to force the police to tell us where they are. >> they have been virtually silent about the disappearance of 43 students who were attacked by local police and gunman in a troubled state of gedero. the police refused to sprain why it took so long to take government action. >> we're not going to conduct an

interview. >> the story is getting very little attention in the mexican media especially here in the capitol where some people respect even aware that the crisis is happening. the missing students didn't make the front page of a leading mexican newspapers for three days in a row this week. it's a common belief among many mexicans that the lack of media attention is intentional and some find it disturbing. >> the media is hiding everything, and instead they're talking about other issues creating a smokescreen. instead of telling us about what is happening with the students. >> michael: anger is growing. protesters blocked major highways. they're now threatening to take over government buildings if they don't get answers as to where 43 students disappeared. rachel levin.

>> and are people heeding the calls of people taking pictures of themselves. stop snapping away of an important occasion and what be a very important journey in their lives. >> it is a very important journey in their lives. no, they're not heading the call by the clerics. we've been talking to people and keeping on and taking selfies that they need to document this very important step in their life. they also point out that as long as you're not doing anything unlawful i, just taking a picture with you and your partner or your family member, there is not a problem with that. using the state of art

technology, and making sure that the hajj doesn't have any issues. >> eid is normally a joyful ti time. >> reporter: houthi militiamen, state security is nowhere to be seen. most of these gunmen only have limited education and never lived in a big city. people here tell us they're nervous about houthi gunmen taking law and order in their own hands. they're also concerned about money. they say providing basic needs is a challenge. >> this year is worse than the previous. war has affected everything. >> but on this holiday yemenis dig deep in their pockets because every family will buy a

lamb, new clothes and gifts for the children. >> i've been saving money all year so i can buy gifts for my children. >> during the last few days you could not see a crowd of shoppers like in in sanaa. it allows yemenis to forget about insecurity or the fact that they don't have enough money in their pockets to buy anything for eid. even the poorest come here to spend the last penny they have. and. >> we sell more at the moment because in times of war more people come to buy more goods. for fear they won't be able to find any later. it's not like this normally. >> it depends mainly on oil production, but this has declined from half a million barrels today to less than 200,000 this year. it's partly due to lack of
