directions are null. built upon as the basis of legitimacy. hadi also called on the international community to maintain legitimacy in yemen and to offer economic support. but according to many yemenis especially among hadi's supporters, the statement ignores several key issues. most importantly the question of his resignation. hadi's escape is seen as a game-changer. just a couple of days ago his opponents as well as some of his former supporters agreed on a new legislative body intended to lead up to a new form of government. hadi's reemergence from the shadows has made it difficult to ignore him and to go ahead with that plan. his resignation has not been approved by the parliament. so constitutionally he is still

>> government has put on a display including military hardware captured in the east that it says provides material evidence of russian involvement in the fighting there. there are video booths showing what's described as russian television propaganda. and the confessions of captured soldiers said to be russian. it's all clearly having an effect. >> this is russian aggression for our country. >> do you think ukraine should respond with force? >> yes, of course, yes because military of russia, russian soldiers attack our lengths. >> new arrivals are registered daily. people with no idea of when or whether they'll see their homes again are given food and

shelter. >> translator: i really hope, but unfortunately my hope is melting with every passing month. because of the situation in my city and in donbas, and it's getting worse and worse. i'm afraid that when he i do go home, there will only be ruins. >> reporter: ukraine has other problems, an economy on the verge of collapse and corruption. as a form he economy minister told me keeps foreign investors well away. >> ukraine has two fronts. one on the eastern side, where we are fighting the external aggressor and from the inside. both fronts are extremely important. and without a victory on both fronts no success can be ensured in ukraine. >> in a sense kiev has no

choice but to fight fire with fight. if the current ceasefire fails the government will have to prepare its people for along battle and hence the pr offensive galvanizing the people for war. the enemy is not corrupt politicians nor even separatist fighters. government wants the people to know that the enemy is russia. jonah hull, al jazeera kiev. >> now in russia thousands of protesters continue to come together to voice their anger over the ukrainian government's actions. antirussian sentiment is growing partly due to state television coverage of the cries. there is more fighting between myanmar and china.

between myanmar's army and ethnic rebels who want greater ton my. adrian brown reports from the border town of nan san in china's hunan province. >> symbol of the economic hopes china has for this remote region. but today it's been transformed into a refugee camp overflowing those who fled the fighting. like those on this side of the border they're ethnic chinese and with accounts of brutality by myanmar's army. >> translator: the soldiers caught me and hit me again and again like this, just like this on my own head. >> reporter: the farmer arrived nine days ago. >> translator: they took most of our cattle. i only have a few left. it is a big mess there. it's too dangerous to go back.

we're afraid they might kill us. >> reporter: elsewhere families squat in an area of partially built shops fending for themselves as best they can. the military's in charge of its humanitarian operation. a soldier shouts at the refugees to go inside. he doesn't want us filming them. sometimes the soldiers succeed. behind me are some of the 30,000 refugees who have crossed over from myanmar into china during the last few days. and behind me there are chinese soldiers who want to prevent us from filming. this is a tricky situation for china. tricky because some of these refugees want china to support their campaign for autonomy but beijing insists it doesn't

interfere in the political issues in other countries. some of the fighting is going on in the town of lokang just visible in the distance. this is as close as they can get to home. adrian brown, al jazeera on the china-myanmar border. the myanmar representative from the scenario for humanitarian dialogue. talk to us about the humanitarian situation and how the fighting has affected the refugees. >> sure. this has been some of the most serious fighting, the clashes started over ten days ago. as your report indicated we have had 30,000 displaced and serious impact within the myanmar

itself. we have seen a convoy come and you tack, significant displacement. this is a real concern for those working in the country on the peace negotiation is because it does have the potential to derail many years of hard work that have been put in by the ethnic groups in the government to try to stabilize the situation to have ceasefires and political dialogue that this type of event doesn't happen in the future. >> what are the chances of that happening at this point in time? >> well, i think the worrying situation at the moment is this is likely to play out militarily over the next few weeks and the fighting is likely to continue and even worsen. the myanmar military per seefs this as an encouragement to its territory, in 2009 they launched an operation to push back the kokang ethnic leader who has

since been in hiding. this recent attack has been from the kokang group to regain that territory. from the myanmar perspective their military would strongly, they are going to be looking to respond very aggressively, so although dialogue and negotiations might help to deescalate the situation what we are likely to see in the coming weeks is continued fighting. >> this situation will only be resolved within myanmar we heard our correspondent say china is quite reluctant to get involved in this. >> i think the geopolitics is quite complicated. china doesn't want to see the fighting on its border both for the humanitarian impact and also because it has enormous financial and energy interest at stake in meen mary myanmar.

a perception amongst the public that the chinese government has led some support to the kokang rebels, yesterday we saw a press conference from the myanmar officials in which they accused the chinese of gathered with the kokang. less on the specific contact in koka thrvetiong and more to reach nation wides agreement. we have seen talks last year but we're not quite there yet and because of that that's one of the reasons why the situation in kokang is especially worried. >> good to talk to you. adam cooper. inner for humanitarian dialogue. thanks for your time.

picture. but i think you can look at it the other way it would give a platform to the smaller films that would never be seen otherwise. big bump at the box office, more people go to see it because of that. >> nancy are shriver her take on the issue: >> we really need the oscars, to be highlighting the smaller films and i think that's probably why you see most of them being nominated whereas the block busters have such a big machine behind them, they don't need any help. >> for those who don't get a nomination you can always look ton bright sigh, to the make rs ofersof the lego movie.
