tea? i'm meeting a tea taste tore find out in northeast india. we begin with that raid on the tunisian army base which has left 45 dead. the assault was launched by armed men from across the border in libya. it happened in the town of ben garden. we are on the line now with our reporter in tunisia. what do we know about the attack? >> i was there in the center of the town which has basically become a ghost town with people staying indoors. that's what they've been advised to do. what we understand is that this was a very well coordinated planned attack on army barracks just outside the center of the

town. there were clashes, some heavy gunfire was heard throughout the town that went on for a few hours, and when we were there, the situation was extremely calm, the police had set up checkpoints in and around the town asking people to basically just stay indoors if they can. i this in what the police and security forces and army are trying to do, they are trying to find out if they have gathered all the armed fighters. if they managed to find all of them. there were reports of some locals that there were up to dozens of fighters going into the neighborhood and basically carrying out these attacks. >> what was the motive for this attack? why would armed groups want to do this? >> it's unclear at the moment, but i think a lot of people here would point the finger at libya and say that this is connected to what has been the growth of isil in particular, as well as other armed groups in libya in

the past year. now, there are, according to the minister of interior, around 3,000 tunisians fighting right now. a town was attacked by u.s. airstrikes just in the past few weeks. that is very important, because it's known as a training ground for tunisians who were in libya, based there and training there, so there is a lot of speculation right now and it is speculation i have to say that this attack here is somehow connected to what we've seen at military intervention in the west of libya in the past few weeks. >> many thanks. difficulties have emerged at an emergency summit over europe's refugee crisis. a draft communique reported by journalists sunday declared that

the route north through the balkans is closed. thousand us have been stopped at the border between greece and macedonia. the path it shut and their path barred. german chancellor angela merkel said every country including greece must understand that this can't be about closing something. al jazeera's jonah hull is live in brussel where that summit is taking place. we are talking about some countries here on the route north that aren't as yet in the e.u. june that's right, they are sort of stepping stones on the route that takes them from greece all the way essentially to germany. greece is in the e.u., macedonia isn't, and so on. i must tell that you that has emerged now as one sticking point, if there was any

momentum, any positive vision during this day, it has largely diminished because german chancellor angela merkel said i don't like that language, language that has been in a draft for days now. that is going to be a problem for the 28 members of the e.u. to sort out. there is now a bigger problem that confronts them. that is that we've just heard that this summit is actually extended. it is extended at least turkey's participation in it is extended for the prime minister who was due to leave shortly after lunch for a press conference. that is canceled and he is staying on until dinner. what we are told is that turkey has put you a new proposal. they are going to have to study a proposal that goes further without giving details about what's actually in it.

economic migrants have been pushed back because of border closures who are now pooling in greece with nowhere to go. turkey, it had been build here was going to agree to take them all back and then repatriate them to their countries of origin but it doesn't appear that be that simple. turkey looks like it is demanding far more in return for that than it had once believed. it had resettled syrian refugees on european soil. there are trust issues. president erdogan on television a short while ago saying they still haven't paid us the $3.3 billion that they promised four months ago and it wants a sped up e.u. membership action plan to go into force right away. these are issues at a time when turkey is in the news for all the wrong reasons, shutting down its biggest national newspaper.

we all know here in brussels that it's going to be a very, very long night ahead. >> jonah, many thanks there, live from brussels. >> nine people have been killed in a suicide bombing near a court believe in northwestern pakistan. three police are among the dead. 27 others were wound the in the attack. eyewitnesses say police stopped the suicide bomber from entering the court compound in the town. a group if i am indicated with the pakistani taliban said that it's carried out the attack. >> thousands of palestinian teachers are holding a sit in in the prime minister's office in ramallah. they are demanding a pay rise after being on strike for nearly a month now. the walk out has left millions of students across the occupied west bank out of school. al jazeera's marie basher reports from ramallah. >> a big crowd of palestinian teachers did manage to gather here in the center o ramallah

despite reports many were turned back at checkpoints in different parts of the occupied west bank by palestinian security forces. the teachers are angry because they say they haven't been given a pay raise. they have second jobs to make ends meet. >> the government said it will only deal with the official teachers union, but many striking teachers reject that union, saying it's far too close

to the palestinian authority. the head of the union has accused some of those mobilizing these protests are being politically manipulated by different parties, but many people we've spoken to say they are not interested in politics. they just want to get a decent living wage. what is clear is this is the largest grassroots mobilization of palestinians for a long time. >> contaminate waters dominated the latest democratic debate. bernie sanders and hillary clinton went head-to-head in flint in michigan state where the local water supply has been contaminated by lead. we have this report. >> the headline at the flint debate, why almost two years later, the water in this city is still contaminated with lead and if president, what each democratic candidate would do about it. >> president sanders would fire anybody who knew about what was happening and did not ability

appropriately. >> i know the state of michigan has a rainy day fund for emergencies. what is more important than the health and well being of the people, particularly children? it is raining lead in flint. >> flint's water became tainted with lead when officials switched the water supply to a more contaminated source to cut costs. water isn't the only issue plaguing flint or the state of michigan. the state has lost tens of thousand was manufacturing jobs as a result of globalization, and trade agreements bernie sanders says hillary clinton supported. >> secretary clinton has discovered religion on this issue, but it's a little too late. secretary clinton supported virtually every one of those disastrous trade agreements. >> if everybody voted the way he did, i believe the auto industry would have collapsed, taking 4 million jobs with it.

>> clinton retains the lead with three times the delegates. she is positions herself as the presumptive nominee. >> thank you very much, everybody, i greatly appreciate it. >> ready to challenge the republican front runner. >> also of last night, donald trump had received 3.6 million votes, which is a good number, and there's only one candidate in either party who has more votes than him, and that's me. >> still bernie sanders did collect another victory in the u.s. state of maine but lagged far behind in the number of delegates need to win the nomination. that's why the upcoming marsh 15 contest in delegate rich states like ohio, florida and illinois will be critical. bernie sanders hopes to close the gap necessary to win the democratic presidential nomination. al jazeera, washington. still to come here on al jazeera, former u.s. first lady

nancy reagan dice at the age of 94. we'll look back on her life. i'm in rural zimbabwe. i will introduce you to a community trying to keep their language alive. >> celebrity chef, marcus samuelsson. >> i've had the fortune to live out my passion. >> his journey from orphan to entrepreneur. >> sometimes in life, the worst that can ever happen to you can also be your savior. >> and serving change through his restaurants. >> we hired 200 people here in harlem... these jobs can't be outsourced. >> i lived that character. >> we will be able to see change.

gardene. thousands are palestinian teachers are holding a sit in near the prime minister's office in ramallah. they've been on strike for nearly a month demanding a pay rise. a draft communique reported by journalists at a summit declared the route through the balkans is closed. german chancellor angela merkel said this can't go about closing something. the root cause at the refugee crisis, the war in syria. 4 million syrians have fled most not to europe, but to its neighbors. we have this report from turkey near the border with syria. >> turkey has more than 2.2 syrian refugees. the unofficial number reaches up to 3 million, they put a lot of

strain an turkey's infrastructure. the turkish government said it has spent over $7 billion hosting syrian refugees since the crisis started five years ago. 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 spent that, the government said it will spend it integrating syrian refugees, they will build more schools, more hospitals and they would give syrian refugees an opportunity to find work and give them work permits. now turkey said it is doing what it can to help the syrian people. >> president barack obama has described her as the woman who redefined the role of first lady. nancy reagan, wife of president and reagan has died at the age of 94. we look back at her life. >> in this moment, nancy reagan

some bottommized the grief of the nation, burying her husband after a long fight with alzheimer's. born in 1921 in new york be a an robbins, nancy was actually a nickname, she became an actress. when she was mistakenly put on the blacklist as a suspected communist, she turned to the president of the screen actors guild, ronald reagan, for help. they married three years later. they did one movie together, but then she put her career aside to raise their two children and to help his political career from governor of california to u.s. president, letting in 1980. >> i think i may have helped a little, maybe. >> 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. >> doing everything we can. >> she denied having that much

control but later admitted she did play a role in her husband's presidency. >> i was always aware more of people who were running him and he wasn't, so i would step in and say you've got to watch out for him. >> that meant she often clashed with his staff, much more so after this assassination attempt when she demanded final say over his schedule. it made headlines when it was revealed she was consulting an astrologer first. as a first lady, she was controversial. raised in a life of privilege, she was often portrayed as an elitest, targeted for remodeling the white house and replacing the china. the money was donated, like her gowns, but that didn't crop the critics. >> she famously urged kids to: >> just say no. not long run, it made very

little to the statistics. out of the white house, she did impact the debate over stem cell research, convinced it could have provided help for her ailing husband, she pushed republicans to abandon their moral objection and it was enough for president george w. bush to find a compromise, allowing some research to be done. er had life, she said really began the day she married her husband. her injection devotion and love for him and her legacy will in many ways define her own. north korea has threatened to launch nuclear strikes against south korea and the u.s. it's in response to joint u.s. and south koreaen military exercises. tension on the korean peninsula has heightened since north korea's nuclear test in january. grieving relatives have met the deadline to file lawsuits over the disappearance of

malaysian airlines flight 370. more than two thursday of the passengers on that plane were chinese. it's been two years since it disappeared and wait for answers is taking its toll on some families, as our china correspondent adrien brown reports. >> the world said greatest aviation communities have touched communities rich and poor. this village is one of them. ads still encourage local men to apply for construction jobs in malaysia. he was one of the 154 chinese passengers on flight mh370. last march on the anniversary of the jet's disappearance, his younger brother told me he believed the plane had been highjacked. he still thinks that today. >> this has had a huge impact on the family. this is endless torture and

pain. we will remain in this abyss of pain as long as it is not discovered. we met the wife and her young son. the family home was adorned with happy memories, but she has left the house after a row about the initial compensation offer. the result is that a child is now in the middle of the bitter family feud over money. >> she wanted to accept the compensation, but my parents did not want to, so she took the son away and did not let the parents visit unless they gave her money, so we grabbed the son back. >> this means his sister in law could now end up with nothing. time has almost run out. the deadline for families to file a claim against malaysian airlines is march eight, two years since the plane disappeared. on the eve of this affords, this family has finally launched a claim, seeking compensation of

almost a million dollars. >> multiple lawsuits have already been filed in australian, chinese, malaysian and u.s. courts, but the campaign for compensation is taking its toll on already broken families who may also never know the real cause of their grief. adrien brown, al jazeera in northern china. two years of rerattic weather and declining production is taking a toll on the tea industry. the state produces 17% of all the world's tea. over the past 100 years, the minimum temperature across the tea growing region has increased by 1.5 degrees celsius. annual rainfall has dropped by 20 meters. we have this report. >> acceptable. >> meet a professional tea taster.

his job is to assess quality, but, he says, tea is subjective, like whiskey or wine, one man's drink is another man's poison. he says he's seen big changes in his 25 year career. >> the growing conditions have become more challenging. earlier in areas where you didn't need irrigation, today you need irrigation, so that's an added cost. >> he has devoted his life to studying tea. he says global warming is having a serious effect on the industry. >> climate change is impacting the productivity in terms of distribution. secondly, the climate change is also affecting the quality. >> there was a time when these sprinklers weren't needed, when the rainfall and sunshine were just right. the tea plant is sensitive. unlike annual crops which

dominate our food system, like corn, wheat, and rice, tea is a perennial crop, which means it's grown all year round. you plant the saplings once and you can harvest the leaves for 50 or 60 years. that makes it especially vulnerable to changes in temperature, and water levels. >> a senior member of the indian tea board and a fifth generation tea planter said unpredictable rainfall has forced tea gardens to install irrigation. >> he we have become completely dependent on nature and we don't rain, we cannot have good harvesting. you can't get your production from irrigation. it is only from rain, when there is rain, then you get good harvest. >> indians consume a third of all the tea produced in the world, nearly a billion tons every year and millions who

depend on it for their livelihood search for a sign of two leaves and a bud. al jazeera in northeast india. remote communities in zimbabwe struggle to keep their languages alive. 16 languages are recognized in the constitution but most aren't widely written, spoken or taught in schools. al jazeera has been finding out how the chard dialects is in danger of dying out. >> these men are in their 70's. they are speaking a language spoken in zimbabwe. it has versus tones and click sounds, one of 16 official languages here, but it's facing extinction. >> currently, there are about 11 speakers between the ages of 45

to 97 and we can say the language is critically endangered, because there are no young speakers at the moment. only 11 elderly speakers. >> he wants to save the language, so he's teaching young people in the community. >> we used to stay in the bush. today our children grow up in societies where there are many people speaking many languages. ours is dying. >> white settlers looking for land forcibly removed them from that you are natural habitat. hunger an anally employment made others leave their homes. they married into other tribes. their language was diluted and in many families, forgotten. >> it's too late for me to learn how to you write it, but i want to speak it. if my children also learn, maybe we can speak it more. >> it has no written records. it's a marginalized language not
