the taliban attacks an air base as regional leaders meet to discuss afghan security. hello, you're watching al jazeera live from our headquarters in doha. also ahead another international conference to try and resolve the conflict is syria even as more fighters head to the war zone. >> what was proposed yesterday is not what this party stands for condemnation after u.s. republican presidential hopeful donald trump calls for a ban on

muslims entering the country. re-engineering the planet, a look at the alternatives if climate talks in paris don't end in an agreement. we begin in afghanistan where taliban fighters are holding a number of hostages after storming the air force compound on tuesday. forces are still locked in a gun battle with the fighters in the residential part of the compound. at least 20 people have been killed and up to eight attackers have also died. the latest from our correspondent. a stand-off has been around 15 hours now. what is the latest? >> reporter: we just have spoken with one senior afghan military official at the scene. he told us that the region it is longer than it is supposed to be

because attackers are holding hostages with them and they want to be careful to not cause any civilian casualty. he confirmed that they are fighting the attackers. at least nine attackers are now killed and they believe three more on at the area it is a highly secure area, it houses the joint nato and afghan military headquarters. how were the attackers, the taliban, able to get access to the site? >> reporter: as you said, the compound is a huge one, one side being a military side and the civilian on the other side. the main base for the region of afghanistan. also it's the main base for nato

and u.s. forces that are operating in the southern of afghanistan. in this particular compound which is the residential compound, it is inside the airport and getting into there you have to cross at least two or three check points. it raises questions that how come not one or two, at least we believe that 11 or 12 taliban attackers with a.k.47 grenades and suicide vests could manage to enter the compound and to get hold of the location thank you very much. lots of questions, obviously. live for us there. the attack comes as regional leaders are meeting in pakistan's capital for a conference aimed at supporting afghanistan in the fight against armed groups. the opening of the meeting on tuesday, afghanistan's deputy foreign minister said the only

way to defeat them is to have a global and united strategy. the two-day gathering will also focus on energy, infrastructure and investment deals for afghanistan. >> this vision of a peaceful stable and prosperous afghanistan which is in the best interests of the region is far from becoming reality unless we put an end to financial logistical and idea logical support in our region. we believe that our country can act as a catalyst to collect regional cooperation more on this to political analyst. we have an ongoing attack and then this conference. quite significant the timing. what exactly is the afghan

hoping to get out of this conference in the pakistani capital?

have this feeling that they are ready to cooperate the pakistanis have said that they're ready to negotiate again. get involved in negotiations with the taliban. we know that the peace talked have stalled in recent months and we hoped that they will continue after june, but they're wanting to bring the taliban back to the negotiating table but you couldn't do this and bomb and fight the taliban at the same time. >> the pakistanis could not deny that they have control over taliban. look what happened after the announcement of the other day. they gathered in pakistan to pick up the new leader and he was wounded and his state is unknown. pakistan is aware of the taliban

leadership, they have determined the control over the taliban and they could play a key role if they want to have peace in pakistan. i don't think that the afghan government could meet all the conditions of pakistan is asking in the meantime, we have seen militant violence increase over afghanistan over last year. what does this is an about the future of the country-- say about the future of the country?

not in good shape. they're having the problem over the new leadership of the taliban and also there has been some infighting amongst the taliban. also there is the emergence of i.s.i.s. which is a problem. the overall situation is certainly very problematic not only for the afghan people, but also our international partners because they're watching it very closely thank you for that. world leaders are planning to meet in new york next week to discuss the war in syria. u.s. secretary of state john kerry made the announcement after holding talks with ban ki-moon. they are pushing for formal talks. >> we talked about syria and the need for the u.n. negotiations to be able to begin and hopefully for a cease fire to

able to take effect when and if we can achieve that john kerry says international talks in new york depends on factors, including the outcome of a meetings. they hope to come up with a unified voice. others have not been invited such as the al-nusra front. they say they are optimistic. >> reporter: most of the opposition committees are present here. the vision regarding the political solution about the transition process, a big portion of them are in agreement with each other russia has voiced anger over the presence of turkish troops

in iraq. moscow brought up the issue at a u.n. council meeting. the u.n. are calling on iraq and turkey to work out the dispute. turkey says its soldiers are training iraqi forces to fight against i.s.i.l. iraq says talks with ankara are going well. republican presidential hopefulful donald trump is facing a back blush after calling for muslims to be banned from entering the unites states. -- united states. >> i am officially running. >> reporter: from the moment he announced his running, he has been testing people with his rhetoric. many say he has now gone too far. >> this is not conservative im.

this is not what this country stands for. >> reporter: there are many muslim members of the congress and armed forces who are americans who are assisting the country. still he wants to close the borders to those who practice islamic faith. >> they should be stopped from entering the united states until the country can figure out what the hell is going on. >> reporter: trump's comments were met with applause. not all conservatives support him. many republicans believe

religion must be protected. anyone who case about religious liberty should denounce this wreckless rhetoric. the government should not penalise law-abiding people especially those who are american citizens for holding their religious convictions. >> what mr trump said is deeply offensive. as a secretary of homeland security said, has consequences for national security. the real question for the republican party and for the republican candidates is are they going to be dragged into the dust bin of history along with donald trump? >> reporter: >> what you're actually seeing is that people are starting to rally around everybody butt him. in other words, in some strange way he is unifying the party against him.

>> reporter: a party that right now appears angry, anxious and amplified coming up on al jazeera, violence in the west bank after a 19-year-old palestinian is killed during an israeli raid on arefugee camp. amp. sure, tv has evolved over the years.

it's gotten squarer. brighter. bigger. it's gotten thinner. even curvier. but what's next? for all binge watchers. movie geeks. sports freaks. x1 from xfinity will change the way you experience tv.

welcome back. a reminder of the top stories.

taliban fighters are holding a number of hostages after storming the air force compound on tuesday. forces are still locked in a gun battle in the residential part of the compound. the u.s. secretary of state says world leaders are planning to meet in new york next week to the be conflict. it will hinge on several issues including the outcome of a meeting in saudi arabia. u.s. republican presidential hopeful donald trump has called for a complete ban on muslims entering america. the white house says his disqualify him from running for president. israeli soldiers have shot dead a palestinian protester in the occupied west bank during a raid on a refugee camp. according to residents 19-year-old had come to protest against the arrest of two men

when he was killed. >> reporter: the confrontations that ensued in beth le hem between the army and the youth followed the funeral that was killed in a raid in a refugee camp following his funeral palestinians marched and confrontations ensued. it really has become a flash point over these kind of confrontations where palestinian youth vent their anger, frustration at the occupation. when you speak to them, many of them will tell you that the world has forgotten them, that nothing seems to be on the table to deal with this issue. there is a simmering frustration that is becoming the norm.

we see it almost on a daily basis, also incidents of stabbings, car rammings, all becoming something that is happening on a day-to-day basis. certainly a very tense street, a lot of instruments tryings, even in the words of the u.s. secretary of state john kerry, it is very much involved in trying to get a solution to this conflict. he said he hadn't seen the mistrust as high as it is now between both sides hundreds of people rescued from the armed group boko haram will be reunited with their family soon. >> reporter: they are finally free. these are some of the 900 hostages, mainly women and children, who have been freed after days of fighting between boko haram and regional forces near cameroon's border with

nigeria. >> translation: i was taken. i was put in a prison. >> reporter: soon he and others will be on their way home. >> translation: we've received strict instructions from those above us to support them. we have seen humanitarian support. there is already a place for them to rest. >> reporter: the government has already deported thousands of other nigerian refugees. it is concerned about potential boko haram hiding among them. dozens of its citizens have been killed in attacks blamed on the armed group. thousands of young men and women have been taken by boko haram over the last five years. many of them have been forced to join the armed group. there has been a growing sense of frustration that after 19 months there has been no news of more than 200 people, an attack

that has drawn to boko haram's actions in nigeria. the girls and their freedom can take longer. this man is related to three of the missing girls. he says they aren't giving up hope. >> i have not seen anything difficult in negotiating the release of these girls for the government. i am very, very hopeful because it is not just possible to have over 276 girls taken, just to disappear like flies. >> reporter: troops are under pressure to end the boko haram violence by the end of the year. as the fighting intensifys, emergency relief aid agencies are preparing for another way of displaced persons in argentina christina kirchner will hand over power to

the knewly elected president, macri. a report on the legacy of christina kirchner. >> reporter: her combative style has won her enemies and fans. after eight years in power, she is stepping down as president of argentina and her legacy will be debated as much as her years in power >> translation: if there is something that i am proud of, we have reestablished rights for argentinan people without difference, rights for everyone. >> reporter: she became argentina's first elected female president following the government of her husband. together they created kirchner, a movement within the party centred on the presidential couple. nationalism, a strong government

influence on the economy and human rights, have marked her years in office. >> translation: human rights, social inclusion, we are owners of our economy. argentina is different with christina >> reporter: these people say that christina kirchner have made them believe in politics again because she has brought justice to argentina. in the 1970s and 80s, thousands of political opponents were put on trial. >> reporter: there are thousands who continue to support her. but many say she has done more damage about good >> translation: her fortune has grown one thousand%. we have a president and vice president that are leading. >> reporter: christina kirchner

has been close to power since the 1980s as wife of a powerful governor, a senator and then president. her roll after she steps down continue tos to be debated. >> translation: she said she is going to be with the people, supporting them. i don't see her retiring and leaving all her ideals behind. >> reporter: she has been a polarising figure and while many will be celebrating her leaving, others will be waiting for her to return brazil's supreme court has suspended a committee tasked with whether deciding whether dilma rousseff will be impeachd ed. she was accused of mismanaging the budget. a coca-cola add in mexico that

was hoping to inspire joy and unity has done the opposite. a rights group complained it was racist. >> reporter: coca-cola meant this to be their latest heart warming christmas ad for mexico. putting up a tree and handing out coke to dark-skinned people. the company says it was meant to inspire unity and joy. instead it has inspired complaints saying the ad is racist. >> they create two kinds of people, the people that is happy and white, but these people go to an indigenous town and they give happiness with coke and with christmas. the people from the community only have specific. >> reporter: the back lash has

been so great that coca-cola has pulled the commercial entirely. this is part of a statement they sent us: the reaction might be a surprise to coca-cola, but from the times of the spanish conquest to today, dark skinned mexicans have oven been portrayed as opposed to white skinned mexicans. >> reporter: this town featured in the commercial and they told us they were happy coca-cola came. these are among those who featured in the ad. >> translation: when they took it down, i was disappointed because people were saying things that weren't true. they said we had been humiliated

and it was the opposite. we were proud to be recognised. >> reporter: coke is easily mexico's biggest selling soda. it has been in the country for decades. it is going to make more than a suspect ad campaign to change their view the president of the climate change summit is hoped a deal will be reached by friday. they're negotiating an agreement to curb greenhouse gas emissions beyond 2020. the french fortunate minister says the four-year process is about to become reality. while the focus on the climate talks in paris is on cutting emissions, scientists around the world are working on technology to help tackle the problem of

global warming. >> reporter: at no time in the last 800,000 years, possibly longer, have carbon dioxide levels been as high as they are today. the greenhouse gas and here you can see its movement around the globe, mostly comes from human activity. it traps heat and has resulted in a steady rise in global average temperatures. what we can see here which is warmer oceans. if we can't reduce these emissions, thin scientists have suggested at looking at other ways. reflecting more of the sun's energy back into space would result in a cooler earth. one idea is to brighten the clouds by spraying salt water into the sky although there is no evidence to suggest that would have a significant impact. another expensive and unproven idea is to place reflective mirrors in orbit to block the

sunlight. another one, which resulted in over 120 million towns of sulphur dioxide into the atmosphere. >> that sprayed into the upper atmosphere, we could cool the planet and if we continued to spray sulphur dioxide into the atmosphere, we could continuously cool the planet and offset some of the greenhouse warming. >> reporter: it damages the ozone layer allowing dangerous race through. >> they would have to dramatically step up over time as the carbon dioxide every time, step up the engineering to try and counteract it. >> reporter: scientists have also been looking at ways the ocean takes co2 out of the

atmosphere. in new zealand they tested adding iron to the sea to trigger a bloom of small plant and plant-like organisms called photoyorganisms >> this could have negative impacts on the ocean without having the long-term removal of co2 that is needed to counteract climate >> reporter: other technology and development clues large machines that take are bondi oxide directly from the air-- carbon dioxide. >> they're all hypothetical. they will take time to develop and be relatively expensive. >> reporter: to believe that there is a quick fix to climate change, most of the ideas being explored only offer a short-term and local solution. they are largely expensive, unproven and could in some cases potentially make things worse.

new technologies do have a role to play, but most scientists say they won't ever be a substitute for reducing carbon emissions a reminder that you can keep up-to-date with all the news, all the very latest on our stories on our website aljazeera.com can afford to pay for it. the doctor has told you you're sick enough and the tests and the insurance company says?
