foreigners trapped in yemen are desperate to leave. about 350 indian citizens left to djibouti last night. for all those who remain there are growing concerns about humanitarian crisis and no sign of a cease-fire any time soon: >> let's go to syria now where activists say fighters from the islamic state in iraq and the levant have stormed the palestinian refugee camp in damascus. becoming the focus of heavy fighting in 2012 when rifle armed opposition groups moved in yarmouk. a siege there saw many camp residents pushed to starvation and violence has prevented aid groups from doing their work. the united nations relief agency said that it's extremely concerned about the safety and protection of israel as well as

the u.k. foreign minister warning there is morning work to do. >> there is morning work to do, some detail and technical but there is more work to do. we're on it now and we'll continue at it. >> agreement has continued on wednesday and secretary of state john kerry met one-on-one with his iranian counterpart with the sense that talks are entering their final crucial hours. it seems on balance the sides are going to fall short on the kind of agreement they really wanted to achieve here. the you iranian deputy minister said that there are key differences on things like sanctions and iran's right to research and development of key nuclear technologies.

>> now a reminder of the top stories here in al jazeera. the saudi military denied hitting a factory, at least 23 people are killed when the dairy factory in the country's northwest was targeted. activists say isil fighters have seized large parts of the yarmouk refugee camp in damascus.

it's the group's first major attack in the center of the capital. and nigeria's presidential winner said he'll spare nothing to defeat boko haram in his address when ace announced he was the winner. >> although isil fighters have been driven out of the central city, at least three neighborhoods remain under their control. some sewers may find some of the images in the report disturbing. >> reporter: as iraqi soldiers hoist their country's flag in the city of tikrit, the government is hailing this as a massive victory in the fight against the so-called islamic state group. within hours of forces recapturing the city. prime minister hyder al abadi promised to restore normalcy as

soon as possible. >> when it is secured we'll work to return displaced families, god willing iraq will be liberated from isil and their crimes. [ gunfire ] >> reporter: the city had been under isil control for several months now. it is seen hugely strategic because it provides a gateway to mosul where it's pleased that the main leaders and operation leaders are based. but the fight against isil is not so straight forward. as with much of iraq's conflict sectarianism is rife. tikrit is a sunni city, yet the iraqi army used shia militia known as population mobile forces to enter it, who made their intentions very clear raising their flags on their vehicles and even on government institutions. >> they're now itself tikrit, and it will be liberated entire

entirely on a. >> dead bodies said to be isil fighters line the roads a sign of how bloody the battle was. capturing tikrit is a major boost for iraq's army, which seemly folded in isil advances a year ago. but for many this will not solve everything. isil had found support past oppression felt by sunni residents there. many of whom had felt they were unfairly targeted by a shia-led government and army that wanted to wipe them out. and there have already been reports that sunni homes have been destroyed almost immediately after the army recaptured this city. recapturing a city is one thing. but winning back the trust of iraq's sunnies may prove to be more difficult. >> let's go to turkey where the largest city is on high alert after the second shooting in as many days. this time the police headquarters in istanbul were targeted. bernard smith has the details.

>> a man and woman armed with what police describe as long-range weapons approach istanbul's police firing, killing the woman and wounding the man. he managed to escape and was caught not long after. the woman was carrying a bomb. this comes just after 4 hours after a hostage situation at the city's main courthouse where a prosecutor was taken hostage by a left wing group. they held him at gunpoint. the prosecutor was killed and two gun pen were killed after police stormed the room where the process duty prosecutor was being held hostage. they say that this city is on high alert after both of these incidents. >> thousands of pensioners have marched towards the greek parliament to demand their payments be raised back to pre-austerity levels. they're calling on the government to keep its promise

to protect pensions. it's one of the first demonstrations which has put pressure on growth's government since it came to power in january. celebrating april 1st as a red-letter day the day that restrictions on the amount of dairy it can supply will be abolished. it will turn into a major miracle supplier for markets from arab to africa. >> reporter: for all of iron's ambition it is is the humble cow that looks to be a more reliable partner to economic prosper pit. in this farm the lifting of quotas is like the lifting of shackles on the amount of milk they can produce. all over rural ireland they have seen their sons and daughters

forced to move abroad for work during the down turn. no longer. >> just goes on all over the country, every parish in the country. and there will be extra money coming into every parish in the country. >> there is no doubt of the potential hear in this country. the milk flows like water. >> going back to all the problems the irish economy has had the last few years the collapse of the banks all the austerity, the attempt toss rebuild and the idea that agriculture could be one of the foundations of a more sustainable business model. the lifting of the quotas will be helpful. >> markets beg for things like

infant powder and cheese. >> when we bring investors from the middle east to visit our facilities. we don't bring them to our factories. the first place we bring them is down to the farms so they can see the generations of farming expertise that we have for these farms. that's the most impressive things that the international investors see the value we have on our farms. >> in dublin they're beyond excited. they insist their plans will be environmentally sustainable and won't drive farmers elsewhere out of business, and they will encourage food supply in africa. >> north africa in particular, countries that have to import a lot of their dairy products because they don't have the water to produce the dairy volumes that we have the capacity to produce. this business community

opportunity is an exciting one and we'll take advantage of that in a way that is sustainable. >> ireland is a supporter of globalization. ireland is green wet and full of cubs. only a fool would think that there is not a pot of gold at the end of that rainbow. >> we are joined by the european milk board. we can sea from that report that many people are happy about the lifting of the milk quotas in the e.u. your organization, a federation of dairy farmers around countries in europe is not happy about the lifting of the quotas. explain to us why. >> it's not so much the evolution of the milk quotas that we're worried about, but the fact that there are no market instruments to prevent deep milk price crisis in

future. we've had already deep crisis also because of the expanding of the quota despite lack of market demand, and we've seen very low prices in 2009. price went down 30% to 50%. irish farmers who were the first to complain to the european music board that prices were too low. >> for those who don't remember because quotas were implemented just 30 years ago. in the e.u. you used to have milk legs and mountains of butter because more dairy products were being produced than demand. you mentioned ireland but germany say this will give more freedom for commercial decision making and ultimately more responsibility. isn't that the way that farmers should go now? >> well, if you just look at the futures, and how the milk is sold today then you see that we

already have lost today only 11% the prices of butter and powder. we don't get a cost-covering price now. that's the reason that a lot of milk producers have quit, and there are not a lot of young people coming in. only 6% of the milk farmers of the farmers of europe are younger than 35 years of age. and in the netherlands it's not even 3% of the farmers who are younger than 40 years. you see there is no perspective. there is not a good income. we cannot cover the costs. that is really our biggest problem. if the dairy industry wants more milk, they can be very sure about it, but they should pay the price a and they don't do that. right now not at all. >> we'll have to see what develops in the next weeks and months. for the moment, from the europe european milk board. thankthank you for sharing your

views with us. >> thank you. >> scientists say that the world's migrating song bird population is dieing off at an alarming rate. one reason is the shining grass towers of our modern cities. we have reports from toronto canada, on the efforts of one group of activists trying it make a difference. >> very public, not pleasant at all, but a powerful way to show how so many song birds are dying dying. volunteers for "flap" layout a grizzly display of bodies collected at the foot of sky scrapers. just a tiny fraction of those that collide with windows every year. >> everywhere they turn they're faced with some kind of threat. sadly in the urban environment everywhere they turn they can encounter a window. our goal is to try to educate and impress upon the public here is this problem and guess what, there are things you can do to resolve the problem.

>> a new canadian documentary say that many popular species have declined by 60% 70% even 80% in the past decades. buildings and grass are a major cause, and scientists warn that the cost of so much loss will be far more than silent skies from birdsong. >> it's important for the environment. birds do tremendous work for us. they eat insects that you can't even imagine the numbers. yeah, to lose them we'll lose a little bit of ourselves. >> birds see in glass trees reflected back at them. the founder of "flap" say he was inspired by something that happened when he first started picking up dead animals 19 years ago. >> i had had a morning where i picked up so many birds that morning. one escaped in my car and

started flying around my vehicle. he flew and perched himself on my rear view mirror, started to sing and dropped dead in my lap. that was the turning to point for me that i could not walk away from this issue. >> toronto's skyline is soaring and not all of these new glass walls will be bird friendly. still there is one unregulated cause of song bird fatalities that is tin times worse than windows:cats. house pets and feral kill 270 million birds each year in canada. campaigners and scientists say unless something is done to concern that toll, the steep decline in some of nature's best-loved creatures will only continue. >> staying with the animal kingdom, the fear of grasshoppers. if you have it, i suggest you look away now. residents in parts of brazil are battling a grasshopper invasion, possibly millions of the insects

are jumping their way from town to town in the northern state and they're hungry. farmers have watched their crops being devoured by the grasshoppers, which attack in mass. more on our website at www.aljazeera.com. ♪ ♪ >> hi, i am lisa flesher and you are in the stream chances you know someone who has bad or knee surgery, but there is growing evidence that these and other brothers may be used too off and could be detrimental to your health. a game changing way to detect cadgessers early. he is doing it with a smart phone, a 3 d printer and in less than an hour. and later. gnarly half the world's languages will be extinct by
