fleeing -- and men all fleeing. they are exhausted. they have been in the rickety boat for 5 hours navigating through the waters between yemen and djibouti. fishermen fled from a town with his wife and five children. >> translation: we never wanted to leave. we were forced to leave by the houthis, who came to the town and laid siege to it. they controlled everything. we couldn't go fishing. most businesses are closed. we couldn't find anywhere to by food. >> they were offered food. they joined dozens of country men that arrived in the past few days. they'll be taken to a permanent refugee camp. they were prepared to host up to 5,000 refugees. for months they have been preparing for the arrival of

yemeni refugees. there has been a clear division. it's not just yemeni refugees who are arriving. hundreds of ethiopian migrants crossed in search of a better life, and are fleeing back. international organization set up a transit camp. >> it offers transportation back to the country. >> the migrants came back week and dehydrated when they take the boat back? >> they could easily get lost. they offer a medical and psychological help. >> reporter: just as some returning from yemen are bussed home. groups arrived from ethiopia they are eager to reach yemen. they ran to a point where it ran around. they are oblivious to the dangers that lay ahead.

>> let's go to turkey, the largest city is on high alert after a 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 long-range weapons, approaching the headquarters and started firing. police returned fire killing the woman and wounding the man. he escaped and was caught not long after. the woman, according to the man's office was carrying a bomb. this comes 24 hours after a hostage situation at the main courthouse where a prosecutor was taken hostage by two members of a left-wing group. they held him at a gun point. the prosecutor was killed and gunmen killed. where the prosecutor was held hostage. istanbul's police are saying that this city is on high alert

after both of these incidents the palestinian authority is now officially a member of the international criminal court. it's part of a move by the palestinians to increase global pressure on israel. as jonah hull reports, the progress will be neither quick nor simply. >> the palestinian authority foreign minister emerged from a welcoming ceremony at the international criminal court in the hague. palestinians were a step closer to justice, but it will not be quick. >> we seek justice because it is the anchor in which peace and stability can be established. >> do you accept in this might take a long time to bring action against israel to the international court. >> we will not alter the work or the mechanisms established by i.c.c. we want to provide whatever information is available in our hands in order to facilitate and

accelerate the process of an investigation done by the i.c.c. . >> in a preliminary examination of the facts on the ground the prosecutors are looking at two areas of concern, first a settlement building on occupied palestinian land considered illegal under international law, and second. the actions of israel's army in the gaza war last year. it will be for chief prosecutor to decide whether a formal investigation should be launched and later whether charges should be filed. such is the heavy political weight of the israeli palestinian conflict that the court will want to be certain of itself before proceeding. >> it's very premature to speculate on the outcome of the local analysis of the prosecutor. what i think is important at this stage is to allow the prosecutor this possibility, analysing all the relevant

information and arguments, the gravity and type of crimes the perpetrators. one problem is the question of palestinian war crimes. amnesty international published a report into allegations of war crimes committed by hamas. the chief prosecutor here said that she will investigate both sides without fear or i favour. it could expose plainions to charges at the international criminal court. after years of protests over paying low wages, fast food client mcdonald's announced it's raising hourly pay for 90,000 workers. let's get more of this from john hendren live in chicago. what more details do we have about edmonton announcements?

>> this is a big reversal from a major food company. mcdonald's said it will add $1 above the federally mandated wage for each workers. some states have higher minimum wages than the federal wage. they'll get a dollar over that much the federal minimum wage is $7.25. workers get more than that. by the end of 2016 the companies said workers will receive more than $10 an hour. the company is adding vacation. you can accrue 20 hours of vacation in a year. so this is a major change for a company that argued that the minimum wage was appropriate. it suggests however, that there could be a major change throughout the u.s. because mcdonald's is a major employer following wal-mart and target in making the changes.

putting pressure on other countries. that minimum wage has not been raised in some time in congress. they have to hold a vote to raise it each time. this really suggests that that federally mandated minimum wage may be a moot point. the market may be taking over. >> john hendren in chicago. thank you in other news let's go to mexico where the state-run oil company pemex's four died after a fire broke out at one of its platforms. 45 were injured in the blaze which happened in the gulf of mexico 10 months after seizing power in thailand marshall law has been lifted. it imposed another security order meaning the military will retain its powers. the leadership is using the moves to consolidate its control. 60 families have been evacuated

produced. communities like this have seen sons and daughters forced to move abroad during the downturn. no longer. >> there's cows in every parish of the country. they won't all expand but a lot will be extra cows milk coming in to every parish it's across the economy. they should get a boost. >> there's no doubt in the potential. in this country the milk flows like water. >> thinking back to the economy. the collapse of the bank the austerity, and the attempt to rebuild, and the idea that agriculture cap be a foundation zone of a sustainable business model. the lifting of the milk quotes came at the right time for the country. and this is white gold. ireland will export 90% of what it produces. a small county can't produce much but they beckon for things

like infant powered milk and cheese. >> we bring in customers from the middle east to visit facilities, we don't bring them to the factories, the first place is down to the farms, so they can see a degeneration of -- a generation of farming expertise that we have. that's the most impressive thing, the farmers we have on the farms. >> they are beyond excited, existing plans will be environmentally sustainable and will not drive farmers out of business. they see a role for ireland in encouraging food supply. markets like al jazeera. for countries that want to import the products. they don't have the water to produce volumes that we have to

produce. this business, commercial opportunity is exciting. we are going to make sure that they can take advantage of that. >> ireland is an enthusiastic supporter of globalisation. the emerald isle is clean and wet and full of cows. now, a phobia of grass hoppers - if you have it i suggest you look away now. residents in parts of brazil are battling a grass hopper invasion possibly millions of the insects are jumping from town to town in the northern states. farmers watched the crops being devoured by the grass hoppers, which attack on mass. some producers say they'll have no fruit at all to sell next
