european leaders hold an emergency summit on the refugee crisis as thousands are stranded on the greece-macedonia border. you're watching al jazeera live from doha. also ahead, tunisian security forces under attack after armed men launch a raid across the border from libya. palestinian teachers defy a security crackdown to protest in ram ala. they're on strike for higher

pay. >> reporter: i'm meeting a tea taster to find out in the climb change has an effect on tea leaders from europe and turkey are arriving in brussels right now for an emergency summit on the continent's worst refugee crisis since the second world war. our correspondent is in brussels covering the summit. there are high expectations there today. >> reporter: yes. there are. it has been builder's krumplyg time for the ur-- you crunch time for the refugee crisis. a glimmer of light at the end of the tunnel and that sort of thing. the president of turkey said that he saw a possible turning point in the crisis.

they believe all of these leaders here that they're zeroing in on the possible solution to this crisis. one dependent on help from turkey. at the moment they will be working on possible language to declare the so-called balkan route over which thousands of people gone having crossed as far as austria. what that has done because national borders have been controlled, is push back a huge number of people deemed to be economic migrants, not refugees, and people deemed to have failed in their asylum claim. they're growing in a huge body of people in greece in desperate conditions with nowhere to go. that's where the focus of the solution lies that e.u. wants turkey to agree to large-scale

admissions of those people so they can be repatriated to their countries of origin. tur we want the e.u. to resettle many of refugees on the border. it is a good plan on paper but difficult to implement because there is zero consensus amongst many members of the european union here and very little appetite, indeed, for any more refugees to come their way whether legally or otherwise we have heard from the greek prime minister earlier talking about the sort of help greece needs. what is europe going to offer greece? >> reporter: again, this will be discussed later in the day after meeting with turkey when the european council, that's all 28 leaders, get together and have a meeting to talk about the progress with turkey but also

the issue with greece because there is an enormous humanitarian disaster brewing within the european union inside greece and this is a country, of course, that was stong armed essentially-- strong armed into staying in the e.u. and angela merkel said they didn't keep greece in the euro only to turn their backss on it now. there's some millions of dollars being discussed to help them with the huge numbers of people, but that in itself isn't enough. they have to find somewhere to put these people and for that they need turkish help thank you for that. our view from greece itself. our correspondent is on the greek macedonia border. the question is whether there is any chance that anything that is agreed in brussels will, indeed, stop people from coming to

greece. >> reporter: that is certainly what i think the bigger question for the people here is what will happen to them. if it will stop people, the european union is giving a clear message and you can feel it at the border crossing here which has been, i would say symbolically open over the past few days. we have witnessed a trickle of people managing to get through and every day a whole new set of restrictions. what we're hearing is that there will be a list of cities and gee grafkal places which will not be considered as - which will be considered as safe places so people coming from there would not be granted refugee status. in syria, for example, the people coming from damascus, people coming from latakia and people coming from baghdad, from the south and north, so there is

a sort of gee grafkal selection happening. what happens to those who are here it is the big question none has nowhere to go back to. most will tell you they want to go to turkey specifically the syrian kurds, a large number of them, being in this camp. the greeks are making preparations. they announced that by mid march they will be several hot spots open, places for 17,500 refugees and then the u.n.h.c.r. says it is making preparation to give shelter to another 20,000. so that would cover the people who are here. what happened next to them is really the big issue for greece and the european union as you speak we're watching aerial pictures of this camp at the border there. quite surprising to see how many tents there. tell us about the conditions that the refugees there are

facing. >> reporter: the conditions are very basic, if not actually quite bad. in those pictures you probably see the big white tents. that was the original transit camp for about a thousand, up to 1500 people with no facilities for them to sleep, just to have a rest when they continue with on their journey. it has grown to what you've seen over the past few weeks, all these multi-colored tents. there was not one here when i arrived here. every day it built until the situation got completely out of control. there is access to running water but it is limited. i was speaking to a young refugee this morning from syria and she told me that she wakes up in the middle of the night to have a shower and that's not on a daily basis. also there is a shortage of food. people queue for hours just to get a sandwich because there are not enough hot meals for everyone and the camp is milling with children. 40% of the refugees here now are

children below the age of five. conditions for them are extremely hard. they have been sick over the past few days with the changing of temperature, with rain. mothers are desperate. a lot of mothers travelling alone with kids because their husband is already in germany or somewhere else in northern europe and he went ahead hoping that they would have an easy trip like he had. that is not happening any more. family reunification at the moment is not an excuse to continue your journey thank you for that. in other world news, a tunisian soldier has been killed in a raid in libya. >> reporter: we are close to the area. this is the main road in and out of the town. it is being heavily guarded by

the army and tunisian national guard. it does seem like a very organized attack. some people are talking about dozens of armed fighters. it was simultaneous on the army barracks and guardsment we understand that this is it an extremely situation for the security forces at the moment. it's not clear whether these fighters were in tunisia or they infiltrated from the border with libya which is around 30 kilometers away from the city. it is known as a smuggling hubs for weapons and other goods as well. we know a number of people have travelled to lyn i can't to fight for groups like i.s.i.l.-- libya to fight for groups like i.s.i.l. there was a fight on a compound. that was an important training area for some of those who were

fighting for i.s.i.l. this has really put into question the wall and the fence that the tunisians have built on the border with libya. it does see that it is able to be infiltrated by armied groups, by female carrying weapons, very, very easily. this is just the last in the series of attacks that have been carried out in the past week in this area where people who have managed to infiltrate the border in pakistan nine people have been killed in a suicide bombing near a court building in the north-west. at least three police officers are among the dead. 27 others were wounded in the attack. eyewitnesses say the police have stopped the suicide bomber from entering the compound. a group affiliated with the pakistani taliban says it carried out the attack. thousands of palestinian teachers had holding a sit-in near the prime minister's office

in ram aala. students have been left out of school. >> reporter: there are several thousand teachers, governments, schoolteachers from across the occupied west bank who have come to demonstrate not far from the prime minister's office here, even though they have been told it's an illegal gathering and there have been checkpoints where some teachers have been prevented from coming here. they have been on strike for nearly a month. one of the main chance here has been dignity for teachers. dignity, they say, because the basic salary for many is just $500 u.s. there was an agreement years ago to boost that but it hasn't translated into reality. they're also chanting for justice. justice in comparison to other government sector workers. for example, many teachers

compare their situation to the security forces. for 2015 the budget from the palestinian authority for members of the security forces was one and a half times the budget for teachers' salaries. they say that's simply not right. that has led to the anger which you can sea and hear behind me more ahead, tributes pouring in for nancy reagan who passed away at the age of 94. >> reporter: here there is a dying language and i will introduce you to a community who are trying to keep their language alive. >> "inside story" takes you beyond the headlines, beyond the quick cuts, beyond the soundbites. we're giving you a deeper dive into the stories that are making our world what it is.

welcome back. our top stories on al jazeera. turkey and european leaders are arriving in brussels for an emergency summit on the refugee crisis. their aim is to stem the flow of desperate people. a tunisian soldier has been killed in a raid launched by armed men across the border in libya. at least 21 fighters were killed in the attack. a curfew will begin on monday evening. security forces are killing ten of the fighters. thousands of palestinian teachers have been for a month demanding a pay rise. the route cause of the refugee crisis is, of course, the war in

syria. some four million syrians have fled, most of them not to europe but to syria's neighbors. >> reporter: turkey already has 2.2 million refugees registered. the unofficial is up to three million including other nationalities. they put a lot of strain on infrastructure. the government says it spends over 7 billion dollars hosting syrian refugees since the crisis started five years ago. now, the deal with the e.u. is to put pressure on turkey to stop the flow of migrants. the e.u. is promising turkey with 3.3 billion u.s. dollars. how turkey will spend that, the government says it will spend it on integrating syrian refugees into turkey. they will build more skills and hospitals and they will give syrian refugees an opportunity to find work and give them work

permit. now, turkey says it is doing what it can to help the syrian people in the u.s. presidential race contaminated water has dominated the latest democratic debate. bernie sanders and hillary clinton went head to head in flint michigan where the water local supply is polluted with led. >> reporter: the headline at the flint debate, why almost two years later the water in this city is still contaminated with led. what each candidate would do about it >> i would fire anyone who knew what was happening and didn't act properly. >> i know the city has a fund for rain ee d purpose. it is raining led in flint. >> reporter: flint's water became tainted with led when

officials switched the water supply to a more contaminated source to cut costs. water isn't the only issue plaguing flint or manufacturing. bernie sanders says hillary clinton supported. >> she has discovered religion on this issue. it is a little bit too late. secretary clinton supported virtually every one of these disastrous trade agreements >> if every voted the way he did, i believe the auto industry would have collapsed taking four million jobs with it. >> reporter: she retains the lead with almost three times the delegates. she also positioning herself as the presumptive nominee. >> thank you very much. i greatly prernt it. >> reporter: ready to challenge the republican front runner >> as of late night donald trump

had received 3.6 million votes which is a good number. there's only one candidate in either party who has more votes than him and that's me. >> reporter: bernie sanders did collect another victory in maine, but lags far behind the number of delegates needed to win the nomination. that's why the upcoming march 15 contest will be critical. if bernie sanders hopes to close the gap necessary to win the presidential nomination president obama has described her as the woman who redefined the role of first lady, nancy reagan the wife of the late ronald reagn died at the age of 94. >> reporter: at this moment she symbolized the grief of the nation, burying her husband after a long battle of alzheimer's.

her devotion to him was clear. it was the constant theme of their language marriage. born in 1921 new yorke anne robyns, nancy was a nickname. she became an artist. when she was put on the black list as a suspected communist, she turned to ron reagon for help. they married years later. she put her career aside to raise their children and help his career. >> i think i may have helped a little, maybe. >> reporter: there were often questions about how much she helped. this incident reinforced the idea that she was really running the show. >> doing everything we can. >> reporter: she denied having that much control, but later admitted she did play a role in her husband's presidency >> i was more aware of people

who were in running him and he wasn't. so i would step in and say, you've got to watch out for him. >> reporter: that meant she often clashed with his staff, much more so after the assassination attempt, when she demanded final say over his schedule. it made headlines when it was revealed she was consulting an astrologer first. she was often controversial. raised in a life of privilege she was often portrayed as an elitest. as first lady she championed pairing the elderly with at risk youth and urging kids to just say no. her anti drug message brought the usage numbers down for a bit but in the long run made very little to the statistics. out of the white house she did

impact the situation of stem cell research. president george w bush found a compromise allowing some research to be done. her life, she said, really began the day she married her husband. her intense love and devotion to him and his legacy will in many ways define her own north korea has threatened to launch nuclear strikes against south korea and the u.s. in response to the joint military exercises which pyongyang views as invasion rehearsals. tensions on the korean peninsula has heightened since january. two years of erratic weather has impacted on the tea industry in india.

the weather across the region has increased by 1.5 degrees celsius. rainfall has dropped by 20 centimeters at the same time. our correspondent reports. >> acceptable. good. >> reporter: meet a professional tea taster. his job is to assess quality, but he says tea is subjective like whisky or wine, one monday's drink is another pan's poison. he says he has seen big changes in his 25-year career. >> the growing conditions have been more challenging. in areas you didn't need irrigation, you need to today. that's an added cost >> reporter: he has devoted his life to studying tea. he says global warming is having a series effect on the industry. >> climate change is impacting the productivity in times of the

crop. secondly, the climate change is also impacting the quality. >> reporter: there was a time when these spring clers were not needed. when the rainfall and sunshine were not. tea is a crop which is grown all year around. you plant the saplings once and you can harvest the leaves for 50 or 60 years. that makes it susceptible to water levels. a senior member of the indian tea board and a fifth generation tea planter says unpredictable rainfall was caused gardens to install watering system. >> we could not have go

harvesting without this. you cannot get your production from irrigation. it ask only from rain god when there is rain. then you get good harvest. >> reporter: indians consume a third of all of the tea produced in the world, nearly a billion tons every year. millions dpepd on it for their livelihood are looking at the anxiously at the crop search are fog a sign of two leaves and a bud remote communities in zimbabwe are struggling to keep their languages alive. 16 languages are recognised in zimbabwe's constitution. many are not talkihought or spo. >> reporter: these men are in their 70s. they're speaking a language spoken by the people of

zimbabwe. it has varies tones and click sounds, one of 16 official languages here, but it is facing extinction-- various >> currently there are about 11 speakers between the ages of 45 to 97. they can say the language is critically endangered because there are no young speakers at the moment, only 11 elderly speakers. >> reporter: he wants to save his language, so he is teaching young people in the community. >> translation: we used to stay in the bush. we always spoke it. we never mixed our communities, but today our children grow up in societies where there are many people speaking many languages. our language is dying >> reporter: in the colonial years they were moved from their natural habitat. hunger and unemployment made them leave their homes.

they married into other tribes. the the language was diluted and many families have forgotten. >> translation: it is too late for me to learn how to write it, but i want to speak it. if my children also learn maybe we can speak it more. >> reporter: it has no written records. it is a marginalised language not taught in schools. the vocabulary is limited. the elders are creating a dictionary. there is no words for the fork, the spoon, the car. telling stories and singing old songs is one way of passing the language from one generation to the next. the elders want the language taught in schools. the government says it is working on that. even though 911 fluent speakers may not have much time left, they seemed determined to keep their cultural identity and old language alive for the next generation so that it will be spoken long after they're gone

huge crowds have turned out in havana to see a u.s. band play there. it is the most important performance ever says some. >> reporter: another sign of the changing times. thousands of young cubans here watching electronic stars perform here. this was built if front of here, the american embassy. [indistinc [indistinct] there is a new president both here and in the u.s. and things that bring the

young generations of both countries together like this music, are what is taking this center stage. >> translation: i've come here to simply love the electronic music. >> translation: this is something we've been waiting for, for a long time. thank goodness they've come. >> translation: i came here to enjoy the group. >> reporter: all this less than ten days before president obama comes to cuba for an historic visit. a symbol that will become the norm rather than exception the northern lights lit up the sky across parts of the u.k. on sunday. spectacular colored lights were visible in scotland, northern ireland and england. it is rare to see them so far

south. the lights happen when electrically charged parcel from the sun meets the earth's atmosphere. spectacular. news as always on al jazeejazeem slowly but surely, i.s.i.l. is losing ground in iraq and syria but don't kid yourself. it is far from defeated as a global force of violence. after blitzing across both countries in 2014 i.s.i.l. fighters have spent the last six months getting killed or driven out of some key places. like ramadi in iraq and aleppo in syria. what's more, i.s.i.l. last lost some key road connections, linkining the iraqi city of mosl
