cannot get aid in. we have the latest on the developments. >> warplanes strike houthi positions in the capital of sanaa. the building tv channel owned by the houthies was hit. the sale saudi fighters have stepped up to keep houthi fighters from capturing the port city of aden. forces loyal to abd rabbuh mansur hadi are trying to repel a push of houthi fighters to control the city. but the houthies backed by arm army loyal to ali abdullah saleh hold it's ground. saudi-led coalition say they will not stop until houthies have been disbanned.

saudi arabia accuses iran of delivering weapons to the houthi toss destabilize the region. but the ships are part of an anti-piracy campaign and diplomacy is the only way to yemen's crisis. >> there is no doubt that yemen could not be governed by one political faction. all influential and active political factions would 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 military capabilities of the houthis and their allyies. >> airplane commanders and union it's loyal to former president saleh have told us they have decided to join the legitimate government. they're based in province and they welcome their decision.

>> the saudis are hoping for massive action within the army to isolate former president saleh, who remains powerful in yemen. the border crossing with saudi arabia there are still people trying to escape. >> the situation is getting worse. the >> international aid agencies are concerned about yemen's deteriorateing humanitarian situation. the first to carry medical supplies to aden have arrived. doctors without borders say two tons of medical supplies have been delivered to hospitals. >> one of the men behind the boston marathon bombing has been found guilty of all counts by a federal jury in the united states. dzhokhar tsarnaev was convicted of killing three people and injures hundreds of others in the race of 2013.

alan fisher reports. >> reporter: the verdict was never indoubt as the trial began lawyers for dzhokhar tsarnaev admitted he was one of the boston bombers. it was him they said in opening statements. now the jury has delivered the verdict guilty on all 30 charges. 17 carry the death penalty. but one of the victims said that the jury decision does not bring this to an end. >> we'll all move on with our lives. we'll all get back to some sense of normalcy, hopefully when this is all done. so closure i guess i don't think so because it's forever a part of our lives. >> tsarnaev's attorneys wanted the jury to see him as someone who acted under the influence of his older brother tamerlan. >> the defense team has allowed the jury to start building trust with the defense attorneys. after this almost inevitable

conclusion of guilt the jury will be able to work--to work through the evidence and decide whether or not he's actually culpable to the level that he should should be given the death penalty or the sentence of life. >> it has not been challenged by the defense. that dzhokhar tsarnaev was a deadly, violent young man who knew what he was doing. the jury saw pictures of the injuries that injured suffered and saw the blood-stained note written while hiding from the police. in the u.s. federal cases like this the jury must decide on the sentence. some are concerned the jury has already weighted towards a death

penalty. >> if you're opposed to the death penalty and they say you cannot impose it even in a case such as this, then you're automatically excluded from the jury. if you have a jury to express the conscience of the community, and most of those potential jurors may be excused. that raise as real concern about whether the jury that ultimately gets impaneled is capable of expressing the conscience of the community. >> it could be appealed, that would take many years through the system and boston could put the nightmare behind it. >> allen joins us in washington, d.c. the possibility of an appeal, a long road towards a conclusion, if you like. has the defense done enough to save tsarnaev from the death penalty? >> there will be another hearing where the defense will layout its case that dzhokhar tsarnaev was no more than an accomplice

to his brother in the boston bombing in 2013 almost two years to the date. they will say that it was tamerlan who decided how to build the bombs and carry out the plot and it was tamerlan who coerced and bullied his brother to take part. they would hope in the jury of 12 that they would be able to convince one juror that that was the case. if they do that, then he's likely to get a sentence of life in prison rather than the death penalty because it has to be unanimous. if it's going to be the death penalty. another thing to remember as well, is that this is a federal case. in massachusetts the state itself has banned the death penalty, but because it's a federal case they can still return the death penalty. but in boston the majority of people there are against the death penalty. and so the prosecution the

defense will be hoping that by finding them guilty in all 30 charges, that shows how angry they are with them, but they don't have to go to that extra step and sentence him to death. >> thanks, allen. another look now at some of the other main headlines from around the world. after months of negotiations two wars groups in the central african public have signed a peace agreement of sorts which could bring an end to the fighting. the deal watts signed in kenya between a representative of the mainly christian and of. but the deal is not recognized by members the u.n. of a group of yazidis were
