continues next, live from london. >> hundreds of migrants feared dead in the mediterranean as the number approaches 10,000. >> welcome to al jazeera. i'm david foster. coming up in the next 30 minutes. houthi attacks in yemen saudi arabia and yemen talk about large-scale exercises. and google abusing it's market dominants. and why dark matter may not be so dark after all.

the inter galactic study that has everyone in a spin. as we begin our broadcast. so far the italian cores guard has been unable to find any more survivors from a migrant boat that capsized on its way to italy. those who were rescued on sunday but the charity say that the survivors have told them at least 400 people drowned. and that number is just a tiny proportion of the almost 10,000 who have arrived in europe from north africa since friday. from catania on the finally island of sicily, paul brennan sends us this. >> reporter: the tugboat over my shoulder brought in 277 refugee migrants who are currently being processed over to my

right-hand side where they'll be given identification bracelets. the problem is that the number is just a small number of those who have been found here. the total of nearly 10,000, and they're taken to ports all across sicily and on the italian mainland and even to sardinia, too. the number of dead are estimates, but the figure put forward by the save the children from some 400 dead from one boat which sank from the tail end of last week. even though the italian coast guard said it is has not found any trace of any bodies, the figures that are being put forward for the whole quarter

of 2015 suggests that ten times as many people have died in the mediterranean alone and so far the same that died in the period of last year. >> they said there would be more my grant deaths when italy's rescue mission was shut down. they say that the 150,000 migrants in the one year it was operational but it cost $10 million every month and the e.u. believed that because people were being rescued in international waters, it was encouraging more migrants to make the journey. they replaced the e.u. program with tritai run by the e.u. rather than the italian navy. we'll hear from the spokesman for save the children in rome, and she'll tell us what she thinks needs to be done to solve the crisis.

>> first of all its important that the european union recognize that their shared responsibility to rescue people in the mediterranean and that means also to allocate appropriate resources to increase that capacity. it is also important for example, the syrians were the same groups that departed from situation of conflict to come to europe for a better future, and to find peace. it is also good to find programs programs. it is equally important to better reflect on strategic policies on the country's

countries, to ensure that the political solution response there. otherwise, of course, people could only attempt to depart, to find a better future in europe as well. >> saudi arabia said that the offensive that it is leading in yemen has capabilities. there are been airstrikes in aden where houthies have been carrying out attacks on civilian areas. the arming the militias has helped to curve curb the the

activity. >> air raids have been carry you had out in attacks in roads leading to the city. they've been targeted in aden, so they can't go deep in the city. we've dropped weapons these moves are having a positive impact on the ground. they are doing well, and we're achieving our goals. >> the air campaign has been able to degrade and destroy much of the military infrastructure that the houthis and ali abdullah saleh possess, whether we're talking about helicopters weapons, heavy weapons air defense as well as strategic communications rowed that they have used in order to try to take over yemen. >> we'll be talking with the course upon dent inside arabia in a moment. but first we have the latest on

the operation in yemen. >> reporter: it controls the skies. the saudi led coalition has not deployed troops on the ground. it's relying on popular resistence groups loyal to president abd rabbuh mansur hadi. they have gained some ground in yemen's second biggest city aden and other areas in the south. >> we at the time the houthis we're tired of you. you will never be welcomed here. >> here on the western entrance in aden vehicles speed away. traveling in the option direction ambulances head towards the fighting but can't get very far. >> there are injured people over there, but the houthis are targeting our vehicle. they showed others, and we can't

get to the injured. >> hospitals have been badly hit. some like this one have no electricity. there are reports weapons and reinforcements are being flown in to the houthis. the saudis say that this is one of the reasons why it's take something long to defeat them. this is a war over control of yemen. the control on the ground is crucial. and they may have no choice but to send in ground troops. al jazeera. >> let's go live to. listening to the report talking about the possibility of a ground invasion. tell us what you know about

these military operations, joint military operations planned between saudi arabia and egypt. >> david, to have been to the border just on monday. and we've seen massive preparations there. we've seen heavy artillery and we've seen tracks. we've seen soldiers in big numbers along the borderline and we haven't been told at that time what is going on there except that the order by the government about lapped invasion into yemen today there is increasing talk since yesterday about a massive land exercise between saudi arabia, egypt and probably some other allies from

the gulf states. and this is going to be taken place probably in the next few days probably after a special committee is set to organize it. this can be seen as part of the build up, and part of the psychological war against the houthis. remember this place here where i am, the at the border with yemen, is only the--one of the flanks of yemen. the other flanks near the city of aden they have send warships to the area, and they say this is not intended to be part of what is going on in yemen. not intended to help the youthys, but part of an operation against the pirates. however, with the saudis who are now at war with yemen this can be otherwise. iran is a threat. iran is a threat with yemen. for them to see iranian warships

near the gulf of aden and near the yemeni territory is very alarming and we've seen probably this country is taking every precaution to make sure that no other country including iran will not interfere with glen and yemen. >> addressing a crowd which would restrict iran's nuclear program in exchange for western sanctions being lifted. >> the world must know. the 5 plus 1 must know. the end of the sanctions isn't in this deal then there would be no deal.

>> u.n. inspectors have flown to iran for a visit looking at large-scale explosive experiments were carried out near the iraqi border. google has been accused by the european union by skew skewing it's searches. the commission saying it has been unfairly promoteing--google promoting the google shopping service ahead of its rivals. more from simon mcgregor wood. >> in brussels the commissioner announced something called a statement of objections against google. initially against its price comparison damaging competition. google control 90% of all

internet web searches and they're investigating whether this monopoly is being unfair at the expense of others, which may be better. >> if you view that kind of market power to promote something artificially, to favor it in your algorithm by not giving it the same treatment as other services, then you're using your dominant position to restrict competition. >> today's move comes after five years of complaints by digital companies who feel they have suffered directly from google's practices. >> very soon after we launched we were struck with aal an algorithm algorithmic search penalty. as a business, that is effectively disappearing us from the internet. >> some people are seeing this

as a crucial test of the new digital economy and how big u.s. tech companies are dominating the internet. in europe there is resentment of what is seen as an u.s. monopoly. people want to encourage european competition but in the u.s. that's called protectionism. the e.u. can fine google 10% of its global earnings. that's over $6 billion, and other parts of its business including android mobile system are now under former e.u. investigation as well. google has ten weeks to respond. and on wednesday issued a statement saying: >> google will have a right of appeal and the whole process could take years to resolve but the stakes are high in what

could be a crucial test case for the digital economy. simon mcgregor wood, al jazeera london. >> stay with us. we have this coming up on al jazeera. >> i said to my mother i want to kill myself. >> the i can't i i yazidi women talk about how they were raped and abused by isil fighters. >> hundreds have come together in one place to show off their creations. what have we got here? find out later in the program.

it's fighters are entrenched. isil will expand control sweeping through more areas in the northeast much of ramadi is now under isil control. the iraqi army needs help. >> the battle is very big the arrival is not enough. there is huge pressure from isil from anbar and they want a show for public opinion that we're here. but we will stop them. u.s. military commanders have said that iraqi soldiers need more training. there is concern of the popular

mobilization force it is a force of shia pair militaries and it's accused of carrying out executions and looting in the diyala province. something that the u.s. should carried out. the u.s. has given iraq drones and fighter jets, that demand is unlikely to be meat any time soon. >> in north of iraq hundreds of girls and women from the yazidi community have been freed by isil. they've been describing how they

became sex slaves after being captureed. we have reports from a refugee camp. >> the youngest five ways to pass the time. but there are some who don't want to play, their innocence stolen in the most brutal way. this 17-year-old does not want to be identified, and we're not using her real name. in august of last year isil fighters arrived in her hometown sinjar and forced everyone on buses. each time fighters came to choose the girls they wanted. eventually her name was called. >> i said to my mother, i want to kill myself. i was given permission to use the toilet. i wanted to do it then. >> separated from her mother she was taken and for four months

whereabouts are unknown. >> they took my daughter. she's ten years old. it's been nine months since i saw her. i'm dying every day. i want to see her again. >> only the elderly and very young are freed. they say there is only one thing they need, and that is to be reunited with their loved ones. >> protesters attack the head of a central bank in germany. >> it will be the first-- >> protesters were detained. they would continue with the briefing. for the first time ever the

police believe they have found evidence that mysterious dark matter may not be oh dark after all. what we can see in the universe is apparently 5% of what is out there. this is invisible dark matter makes up 85% of the universe. and it's what holds rotating galaxies together. without it they would fall apart as they spin. it gives it gravity. dark matter, you can't see it. it interacts with gravity. a team found that what happens when the dark matter slows down, suggesting it was interacting with something other than gravity. still with me?

they said that gravity is crucial to our understanding of the universe. >> it's prominent more prominent than anything on the periodic table. although it's common we don't know what it is. it's inadvisable which doesn't help and we're definitely trying to figure out what it's made out of we know that dark matter is very important. we know it deals with gravity. if is so heavy that it pulls together the galaxy that we live in the milky way. but does it do anything else? does it interact with the universe in any other way? the way you figure out how things operate and what things are made out of, you pick up a lumps of rock and throw them at each other and see where the bits fly, and we've done the same with dark matter we watch

what happens what we found was that dark matter doesn't behave in the way that we thought it was, if it was just gravity. >> hundreds of investors have flown in to switzerland to show off their brains and project. go there and you'll find a showcase of everything from the surreal to the potentially revolutionary. the reports from geneva. >> so much to say so little type. so much to start. everybody loves a buck duck on wheels right? there it is, one duck caught. one inventor satisfied.
