music enters a minor key i'm harry fawcett reporting from the largest piano factorry where they say there is ram for growth on a major scale. >> the day after aid agencies warned of a catastrophic situation in southern yemen medical supplies have begun trickling in. the medical charity doctors without borders said that a ship carrying two and a half tons of aid has docked at the port of aden, and supplies have made it to a hospital there despite clashes in the city. houthi rebels are continuing. meanwhile, iran's state immediate says two iranian warships have been sent to the gulf of aden, but they're there as part of an anti-piracy

operation. >> reporter: warplanes strike houthi positions in positions positions in the capital of sanaa. the saudi-led coalition has stepped up its military campaign to prevent outy fighters were capturing the port city of aden. last week battles showed no signs of stopping. forces loyal to president abd rabbuh mansur hadi are trying to repel a push by houthi fight tours control the city. but the houthies backed by army units loyal to former president ali abdullah sale hold ground. saudis have said their military campaign won't stop until houthis disband.

in the meantime u saudi arabia accuses iran of delivering weapons to the houthis to destabilize the region. but for tehran, the ships are part of an anti-piracy campaign and diplomacy is the only way through yemen's crisis. >> there is no doubt that yemen could not be governed by one political faction. they should stand together to form a government of national unity. >> airstrikes have now entered a third week. it's aim according to saudi army officers is to destroy middle capabilities of the houthis and their allyies. >> army commanders and units loyal to former president saleh have told us they decided to

join the legitimate government. they're based in the province and the coalition welcomes their decision. >> the saudis are hoping for massive action within the army to isolate former president saleh who remains powerful in yemen. the board crossing with saudi arabia, there are still people trying to escape. >> the situation is getting worse. there is already the company advice. >> international aid agencies are concerned about yemen's deteriorating humanitarian situation. the first boat carrying medical supplies to hospitals in aden have arrived. doctors without border say almost two tons of medical supplies-- >> well, as mentioned aden is the scene of some of the worst fighting in yemen. this dramatic video is said to

show supporters helping a wounded comrade to safety. they forced many to flee or to go into hiding. now let's get more on the situation from doha. is the aid getting in to aden? two things that strike me about that. first of all two and a half tons isn't a great deal of aid given presumably the needs on the ground. and secondly, while this said has made it through to a hospital there are going to be enormous logistical challenges getting aid to others who need it. >> we're talking about country that is a poor country many live below poverty line which has been exacerbated by the

fighting flaring up over the past few weeks. hospitals are overwhelmed by the rising number of those killed in the fighting in aden. they say they have no medical supplies, and they need urgent aid to be able to help people. thousands are lining up on the major streets. there is no fuel. there is no access to clean water. basically these are people who are desperate for international support. now, as you said the situation on the ground is not going to help because you have to escort ships towards the port of aden. the moment you get to aden and to move to the downtown aden, we're talking about areas that are still--they're still fighting. it's going to be extremely difficult. unless the international community agrees to a cease-fire

in yemen. >> these two iranian vessels that we hear about in the gulf of iran condemns the saudi-led coalition. it's widely viewed. >> the iranian prime minister is in pakistan. the iranian prime minister is in lebanon. the united nations' efforts under way are under way to bring about a settlement. the problem is that the saudis are of the view that the iranians will use the houthis as proxy to spread radical shia

ideology and destabilize the region including saudi arabia. this is the rhetoric of the saudis is the following we're never going to tolerate any force trying to destabilize the region and that the airstrikes will continue until the houthis disband. the presence of two vessels off the coast of aden is going to cause more escalation unless we see more in the future between the saudis and the iranian. but the situation is extremely extremely tense there. >> thanks, hashem. >> a federal jury in the united states has delivered its verdict in the case of one of the men behind the 2013 boston marathon bombing. let's go live straight away to allen fisher, who is in

washington, d.c. this news coming up in the last half hour, guilty on all 30 counts. that doesn't leave a lot of room for doubt in terms of whether sentencing is going to go. >> well, it actually douse. the whole point of the moment is whether he's guilty of all the offenses. this is the indictment. there are 30 of them, and he was found guilty on every single one. we knew that that was likely to be happen that he was found guilty on most of them if not all of them. from the start his defense attorney said that yep he did it. the whole idea is to build trust within the jury. what happens now is that they move to the sentencing phase. and the jury will be told by the defense that they believe that dzhokhar tsarnaev was under the influence of his much older brother, and that he acted almost under duress. that might be hard to prove but in a jury of 12 they only have to convince one that he was

perhaps acting under that duress. and that would mean that he gets life in prison rather than the death penalty. the other thing you have to remember as well is that this is happening in boston. although boston was touched by this tragedy many people knew people who were either caught up in the bombing or were injured in the bombing or were just there. and it's almost exactly two years to the day since it happened. boston has in almost every single survey in the last 20 years said that it was generally opposed to the death penalty. it is also considered to be a catholic town with many people still going to church there and the catholic church is very much against the death penalty. it may well be that the jury has decided that by finding him guilty on all 30 charges that they have delivered the verdict on what he did and they may hold back on delivering the death penalty on his sentence. that is up to them to decide,

and that's what the defense will be hoping. >> we'll look back at pictures of that day and dramatic events. they were in the united states. of course. what have you heard about the scenes in court as some presumably relatives and witnesses had to relive those moments. what was the reaction of the accused? >> during the trial there were heart wrenching reminisces of what happened on the day of the bombing, including the father of eight-year-old martin richard. he said he had to make a decision on whether or not he talked about his son who died or his daughter who suffered many injuries. when the verdict itself was announced there was very little emotion in court. there were no gasps.

no cheers, no expressions of yes with people getting the verdict that they wanted. instead, dzhokhar tsarnaev stood in front of the court with his hands crossed in front of him with his head bowed. there was a point when he looked over the jury and then looked away. he followed the 30 charges on the sheet of paper turning it over occasionally. the judge now says that they move onto the penalty phase. they'll decide when the penalty is going to be. now massachusetts is a state that has outlawed the death penalty for its inmates. of course, this is a federal trial. although eric holder is the attorney general will soon be retire something opposed to the death penalty. he said it was his job to make sure that the law was applied to the full extent, and in this case he would seek the death penalty. and the prosecution believed they had a fairly strong case not least because remember at the end of that week during the boston bombing dzhokhar tsarnaev was found in a boat not far from

boston from where the bombing took place. there he had written a note trying to explain why they had taken the action that they had taken. that, says the prosecution that he was not under the influence of his brother because his brother was not there but that he was acting on his own. and they'll use that to make sure that the death penalty is imposed in this case. >> thank you. we'll leave it there. now still to come on the program. a plea from the west bank for more help for palestinian refugees in syria's yarmouk camp. and zimbabwe's leader heads to south africa, his first visit there in more than two decades.earning

the piano, a crazy attributed in part to the langlang affect. >> i've been to one of langlang's concerts. when he was very young my mother would say to me, langlang is so good. he plays piano so well. >> one of chip's greatest classical music stars he arrived on the scene just as the middle class one-child families were looking for ways to help their children. >> many families have pianos now. if you keep playing, the parent thinks great my kid does not just run around. i got a kid who is well behaved.

>> the music school has a long european influence of piano playing, but the pug is crossing china and it's supposed to grow by a third by 2030. china is not the only larger piano market in the world but the largest piano manufacturer. a mixture of machines and 2,000 sure-fingered staff make pianos every year a figure that's doubled. >> more and more people become wealthy. people are concerned about the children's education. >> china has three piano per 100 households still has a long way to go to reach european levels

of 20 to 30. but with tens of millions of children committing themselves to piano that is likely to double. >> for more on go to our website www.aljazeera.com. hi, i am lisa fletcher and you are in the stream. some say it is a violation of their constitutional rights. we will check out the online movement. >> correct me if i'm wrong did i stumble into mexico, or is this still the united states. >> plus, futurist predict that by 2020, we'll have our own digital twin. who may make our daily lives even easier, performing tasks and even consoling our loved ones after we are gone.
