>> end to the aggression against yemen. >> in addition to the bombing the saudis have enforce ed an air and sea embargo. starved the yemeni people of food fuel and medicine. the international red cross said the humanitarian crisis is now catastrophic. >> mohamed vall has a report from the area. >> the fighters of the popular resistance committees are loyal to president hadi. they are supported by soldiers from the 35th brigade but are still unable to push the houthi rebels and the soldiers loyal to former president ali abdullah saleh from the city. a similar scene is here in the city of aden. members of hadi's popular

resistance committee fighting continued tuesday night and since the early hours of wednesday. in washington, the saudi ambassador to the united states said the situation in aden required continued military action. >> we are seeing movement by the houthis that is very disturbing in the city of aden where we see skirmishes and we seize movement of houthi troops into aden from three different directions, from adala, from adava and from elhej. >> reporter: conflict continued. saudi led coalition targeted fighting in ta'izz and aden. but the houthis seem far from being broken. they've marched in the capital sanaa which they still control. they chanted victory denounced the saudi led strikes and

promised alegions answer to their leader. and troops loyal to former president saleh joined the march. >> we're telling them shame on you, why don't you face us on the ground, why don't you face us like men. we are solid like rocks. >> reporter: the houthis say they want this war and any peace deal should be based on their early agreement with yemeni political parties which was signed last september the day after they took control of the capital sanaa. meanwhile, the human toll of the conflict continues to rise. >> translator: any woman any child any man they simply were blindly and randomly targeting any of us. >> we are no longer able to receive more cases. it is beyond our capability in the hospital. we are putting patients in the

corridors and hallways. we are putting up to nine people in each room. >> the international association of red cross has called it catastrophic and better access to aid. the saudi coalition says it has launched a new operation with the aim to restoring peace in yemen but so far there are no signs of a peaceful resolution to the conflict. mohamed vall, al jazeera on the saudi border with yemen. >> how much pressure was being put on the saudis to end the month long mission? >> antonio the u.n. estimates nearly a thousand have died in the conflict and tens of thousands have been forced to flee areas because of the fighting. but today both the saudis and

the state department deny that the obama administration was quietly pressuring saudi arabia to call a halt to the air strikes because of the growing number of civilian casualties. >> the secretary and others have been having conversations with the saudis about how we can get the parties back to the negotiating table how we could get to a ceasefire, how we could get to the humanitarian side. the saudis make their own decision along with their coalition partners but we understand the path forward here needs to be dialogue. >> now saudis say as they're transitioning from the operation decisive storm to operation renewly of hoperenewal of hope, they say the emphasis will be on protecting civilians, stopping houthi aggression and in particular, stopping the flow of humanitarian aid to the long

suffering population there. >> we layer iranian war ships and cargo ships are off the coast there this has to be increasing the risk of a confrontation. >> this seems that way. both sides, united states and iran say they're not looking for a confrontation. of course the united states dispatched the aircraft carrier theodore roosevelt to the region, keep an eye on the iranian cargo ships that are believed to be possibly carrying arms or other supplies to the houthi rebels. iran dispatched war ships of its own. they are in the area, along with the cargo ships they claim the war ships are there to protect the cargo ships from piracy. >> thank you jamie. >> meanwhile tensions are high

amid the saudi bombing campaign. thousands of demonstrators gathered in the yemeni capital sanaa today. armed protestors raised the machine guns into the air while chanting antisaudi u.s. and israeli slogans. killed hundreds of civilians and little to slow down the houthi advance. lawrence korb former senior secretary of state joins us from washington, d.c. sir thank you for joining us on al jazeera. the latest saudi attack on the houthis came just hours after they said they were ending their military campaign and after the houthis seized a key military base. if we see this kind of confrontation happening straight away it doesn't make you wonder why the saudis announced the end of their campaign, especially after we hear jamie mcintire say it wasn't because of u.s.

pressure. >> i think state department will deny it, the u.s. was putting pressure on them to start the strategic bombing this large scale bombing and the saudis did that. what they're doing now is more tactical bombing dealing with particular military units. and the saudis basically when they announced the end of it did say we reserve the right to use it again because they don't want the houthis to gain more advantage. >> well everyone's talking about a negotiating peace now. the houthis have asked for u.n. sponsored peace talks. but the resolution passed last week asks the houthis to give up their territory. it seems unlikely the houthis would give up all their gains so easily so where does that leave us then? >> well, basically unless houthis are willing to make some concessions you're not going to have a negotiated solution. but time is not on the houthis side because as you said in the

beginning the saudis are still willing to use military force. they're not going to be able to get supplies in there with the carrier battle group is going to prevent iran from helping them. so at some point they're going to have to make some sort of accommodations and you're going to need a u.n. mediation and some sort of peace keeping force like we had in the balkans. in the end you're going to end up with something like lebanon with each party agreeing and getting part of the political system. >> also yesterday yemeni officials say the drone strikes have believed to be killing in the east, making sure to contain al qaeda's expansion by itself? >> well, there's no doubt about it. in fact with this turmoil going on there al al qaeda in the arabian

peninsula, aqap, which is the strongest component of al qaeda now, did seize a port and they were able to take advantage of nap that's why i think the iranians the u.s. and the saudis are willing to do something because all of them see aqap as a threat to them. >> and just one more point sir. we've heard nearly a thousand people dead, yemen was already the poorest country in the middle east now it's at subsistence level. the red cross saying it's a catastrophic situation. do you think any of that is actually going to have any impact on the warring factions, do you think it's going to make any of them actually make a proper push for peace? >> i think it will. i think seeing all of the horrors going on in the country and all of the casualties is going to lead the people there to recognize that even if they quote unquote win they will also get the international community involved because they don't want to see another rwanda or bosnia

or somalia. >> let's certainly hope so. lawrence korbb thank you very much. >> a ship carrying hundreds of refugees many were women and children. yesterday the world health organization said the fighting in yemen has killed almost 950 people and wounded some 3500 others. >> the latest round of talks involving iran's nuclear program is now underway in vienna. one sticking point the timing on when economic sanctions on iran will be lifted. iran wants all sanctions removed as soon as the deal is implemented. the u.s. says the sanctions should be phased out gradually. >> after the suspect accidentally shot himself in the leg and called an ambulance police found weapons and ammunition and a bullet proof

they set off from egypt not libya. because to the port of augusta. families from syria wondering what will come next. the italian authorities do their best to save lives but they do not welcome these arrivals. and so they've made it, hundreds of young men as as you can see now, many women and young children. they risked everything to come here. yet governments right across europe are desperate to stop this kind of migration. aid organizations assess their health and try to find out whether all these children have traveled with their parents or are alone. >> there are many children arriving many unaccompanied children as well. i met a 11-year-old boy couple of weeks ago in lampedusa these children have not seen anything in their life, 11 or 12 or

eight. this is unbelievable. >> reporter: then they're led away to a reception center, i caught a quick word with yahya. from darfur in sudan. >> i'm looking for a safe place to live. because our country is so dangerous, and there is -- there is a war. >> in catania nino from senegal, waka from gambia. their lives are in limbo and they are lonely. >> i want a better life. because now i miss my mom. i have only my mom now. i don't have anybody else. the time i came here, the family i have is only, this is my family here. i don't know yet what is -- what is my future now? i don't -- be i don't know yet my future now. >> reporter: we talk of this

as an immigration crisis. but the people on the docks at augusta, tired and confused for sure are also relieved. they have crossed a sea without disaster. they would rather be here than in the troubled lands they left. barnaby phillips, al jazeera augusta sicily. >> coming up next a closer look at the extreme repressive conditions drive eritreans to join them. >> and in neighboring ethiopia, outrage over the murders of nearly 30 ethiopian christians in libya.

>> the united nations says 350 of the passengers on the boat that capsized off the libyan coast this weekend were from the

african nation of eritrea most are thought oto have drown. >> in tonight's in context segment, roxana saberi reports. >> the u.n. says more than 3,000 eritreans have fled to southern italy this year, making them the second largest migrant group after syrians. butful die before they make it. >> directly affected by the tragedies, eritrea has been robbed of its youth and its bright young people. >> reporter: many eritreans leave to avoid doing military service or work for the government at low pay indefinitely. abdel made it to a migrant camp in france after deserting the country's army. he said he served eight years.

>> like to be a normal man to have the family, to have a norm life here. that's why i'm out from there. >> reporter: human rights advocates list reasons so many are desperate to leave air trea, eritrea including the most repressive president. >> the government has curtailed most freedoms from movement to compression from religion to association. >> reporter: and this week, most censored country in the world beating even north korea. eritrea defended its system to the u.n saying there is no gross resistance to civil rights in eritrea the prevailing passions andpeaceand stability. but the reality tells a different story.

nearly 30,000 eritreans applied for asylum. many others escaped to israel and other countries in africa. sometimes they're turned away. >> we have no choice. we are trying, that's why we accept what happens to us. >> reporter: the eu is responding to the crisis by offering aid to eritrea but activists say the west should do more. >> they should really put pressure on the eritrean government to change its attitude to change its ways, and allow the democratic transformation go ahead implement the constitution and these people will have a life to dream within eritrea. >> reporter: roxana saberi, al jazeera. >> human rights watch joins us from washington, d.c. bill, did to see you. as we have just heard eritrea

has been declared the most censored country in the world worse than north korea. the situation was worse than north korea at least those of us in the west are aware of the horrors of the north korean regime where we never hear about eritrea. >> it is a country that has been a one-party state since 1993, when it became independent. there's no independent judiciary. there's no independent legislature. no media freedom. no civil society that's allowed to function in the country. so i think it qualifies as a highly repressive regime. >> i've read quotes from eritrea, the repression is so bad, you're afraid to speak to your own family, open prison and pervasive control to describe life there. why has this regime managed to hold onto power under those

circumstances for as long as it has? >> well, it's managed in part through a sort of a revolutionary identity, there's underlying a lot of patriotism among eritreans and a national solidarity that the government works on in ways that indicates anyone who expresses dissent anyone who balks at conscription for life is considered to be a tray or the. so theretraitor. there is indefinite detention combined with conformity, patriotism that really squelches any kind of dissent. >> it starts with this national conscription anybody over 18 man or woman can be basically drafted and not necessarily for

military work. they can be sent to work in the mines, this can be indefinitely. you don't know how long you're going to be in it, and that's why people are running away from it. >> yes and there's question whether the age is 18, there's question whether they're being conscripted prior to that. or what you're required to do. from the testimonies we've gathered clearly indicate that these are oftentimes what would be considered civilian works projects tasks that people are forced to do as essentially forced labor at the hands of the government. >> so what is the international community to do? can it be dealt with at the source with what's going on inside eritrea? because i know some eritreans have criticized eu aid that has gone to the country. they think it just helps

political eleads and it could be better served helping these people dying on the way to europe. >> what we clearly don't want to see is the fear with the pressures of migration, european union member states are going to be trying to engage with the eritrean government to prevent their citizens from leaving the country. that certainly is not the solution. >> and what should be done to help the eritreans who are refugees? because as we just heard as well the numbers are soaring and they're overwhelming especially italy because there's a history of eritrea was once an italian colony. >> about 9 out of 10 eritreans have been granted asylum or what is called subsidiary protection, 9 out of 10 have been recognized as having legitimate asylum

claims. >> bill froelich, from asylum watch, very good to have you. >> thank you for having me. >> meanwhile ethiopia is in three days of mourning after the killing of ethiopian christians by i.s.i.l. sent thousands of ethiopians onto the streets in protests. you united in their condemnation of i.s.i.l. >> people were united in grief on the streets of ads ab. addis ababa. a review was posted online that appears to show the armed group shooting and beheading

ethiopians in libya. >> i want to say to i.s.i.s. militants that they are not with us and we are not with them. they do not represent us and they are not real muslims. ah laallah does not allow this, stop what you're doing stop stop. >> two of the victims were friends that traveled together to get an illegal boat to europe. they wanted to find work. to them i.s.i.l. and those who smug people across borders are the he be enemy. >> i don't want the international community to rest until these devils are destroyed and these human traffickers are rounded up one by one. >> reporter: a large number of ethiopians have left the country because they can't find jobs at home. the government said on is you the it will bring back ethiopians who want to leave licklibya and cover their costs.

>> today marks the 100th anniversary of the first large scale use of lethal chemical weapons, an attack that would change the way wars were fought, the second battle of dupre where the germans released 1 tons of chlorine gas the gas traveled for miles and hurt thousands of soldiers, killing more than 100,000 people and injure more than a million more. last month it started the process of destroying a stockpile from world war ii. rob reynolds has the story. >> a small army of workers in protective gear assisted by precision robots is trying to

destroy one of man kind's most vile resources, chemical weapons. >> we have explosion hazards we have agent hazards we spend a lot of time on our personnel on training to ensure our workforce is ready to complete chemical weapons destruction. >> poison gas was used by both german and allied forces. not effective on the battlefield but terrified the men in the trenches. mustard gas can cause severe burns blindness suffocation and a lingering death. the remaining portion of the gas is stored at a colorado plant. full scale weapons destruction will begin in october. each shell will be carefully unpacked and have its explosives

removed then repeatedly checked for leaks. they'll be taken apart soaked in chemicals blasted with high pressure water and baked in ovens to strip away every trace of poison. these artillery shells are used for training purposes only and don't have any chemical weapons inside of them but there are 780,000 real shells full of mustard gas here at this facility. some live shells that are leaking or have damage, have already been destroyed. >> three two one. >> it's not dramatic but the charges neatly split the shells which are then treated with chemicals. >> mustard gas is within the vessel. that is neutralized with

monoethanol amine. broken down and destroyed all the mustard agent. >> the experts who do this dangerous painstaking work say it's a deeply satisfying job. >> chemical weapons is about the worst thing going. they are dirt 80 nasty. getting rid of them is in my opinionopinion an important thing. >> the stockpile destruction will cost at least four years and cost $4.5 billion. rob reynolds, pueblo colorado. >> some but perhaps not all of syria's chemical weapons have been destroyed. experts believe that egypt israel, north korea serbia, sudan, and taiwan may still have undeclared stock piles. 12 other nations are known to have chemical weapons in the past they include china which says it has destroyed its stockpile and japan which is helping china clean up the

stockpile after world war ii. ann goele la, egypt, north korea and south sudan have failed to sign the agreement. gls also the special >> joining us from washington d.c, charles good to have you with us. there are 780,000 shells of mustard gas at one colorado facility. estimates are that there are millions of chemical weapons around the world. we are in no way ridding the world of these weapons of mass destruction. >> i think we're making progress however. if you looked back 100 years it was on the rise, the use of chemical mu nutritions and chemical weapons. there was a great buildup the early part of the 20th century, the soviet union and

the united states, there are some bright lights here. as you pointed out there's only four countries which have refused to sign the chemical weapons convention which is the treaty which regulates these things. and the number of countries which do have hidden stock piles left is actually getting pretty small. and don't forget two years ago when the syrians finally agreed to get rid of their weapons that was a significant achievement. >> you're right. the chemical weapons convention really has had extraordinary support from most of the world's world's countries. but you mentioned undeclared stock piles. how concerned are you about what those may be, and in how many countries around the world? >> well, of course you don't know what you don't know but the question is, are they likely to be used? i think, you know, north korea which is a notable non-signatory, is probably one of the countries that is least reliable. i think egypt stands out by their not signing the chemical

weapons convention and they have -- they're more or less seen as a responsible country in the region. after syria gave up theirs they really do stand out. i would be looking to them to be acknowledging whatever they have and getting rid of them. but the other countries which are less first line, i'm not sure if they'd use them anyway at this point. there are troubling -- >> you mentioned syria and the horror of what they did in 2014, 2013, they had international supervision, we saw these recent attacks possibly with chlorine gas. do you have any certainty that syria has not retained some chemical weapons? >> well, you know again we don't -- you no the opcw inspectors have done a pretty thorough job of accounting what the syrians declared. the use of chlorine is an open issue. the opcw said it was used,

careful not to say by whom but it was delivered by helicopter, the syrian government has helicopters. it's not like nerve gas not like mustmustard. little impunity to those countries with chemical weapons. to decide to come up with some lethal chemical weapon and be able to produce it very quickly? >> it takes a certain amount of effort to do this. i'm frankly more concerned about biological weapons, in the way you describe it. chemical weapons, there is more infrastructure which is required. they have to be handled very carefully. it requires a larger facility to make. you -- there would be some indicators. i'm not saying it's not something to worry about but i would just point out in the last

100 years i think the risk of chemical weapons has in fact gone down. which is an unusual thing given the way the world has been evolving these days with the growing nuclear weapons and other weapons which can be used to kill people in large numbers. >> and let's hope that risk keeps going down. charles very good to have you with us, thank you. friday will mark 100 years since the mass killings of 1 and a half million armenians by ottomans in world war 1. but recep tayyip erdogan said he didn't expect the word genocide. however pope francis and austria already labeled it a genocide, with germany prompting it the same. white house officials say president obama is likely to shun the term.

critical terms called regression and remorse when referring to world war ii. >> translator: refraining from acts or threats of aggression or use of force against a territorial integrity of any country, settlement of any international disputes by peaceful means those are some of the pledges to remain a nation always adhering to those very principles throughout no matter what the circumstances. >> reporter: the question now is whether mr. abe's words are enough to repair the relationship between china and japan. the prime minister did not use one important term, apology used by his predecessors. the fact that prime minister abe today sent ritual offerings to commemorate japan's war time leader, could be a sign that the
