the man holding the prerogative of the supreme command in the us pay dearly for his speech calling for totally destroying the deep. kathy novak has more now on the threat. this was the north korean foreign minister speaking to reporters in new york after that statement issued by the leader kim jong un talking about the highest level of countermeasure and what that could possibly mean the foreign minister says he's not sure what it would mean but it could mean the detonation of a hydrogen bomb in the pacific so this would indeed represent an even higher escalation of tensions that are already extremely high here on the korean peninsula the unification ministry was asked about this comment here then seoul this morning and said that once again this is an example of provocations followed by sanctions followed by more provocations and that south korea is calling on north korea to stop those provocations now of course simply calling on north korea to stop hasn't

had any effect in the past and we've heard from kim jong un today saying that this latest language in the latest sanctions coming from donald trump the united states and the united nations only reaffirms to him he says that the path north korea is taking is the correct one as far as south korea is concerned it is continuing to urge for a peaceful solution well the u.s. is not the only country putting the pressure on north korea china is also stepping up measures against pyongyang over its nuclear program diplomatic editor james bays reports from new york days after he threatened to destroy north korea militarily now a fresh attempt by president trump economic destruction for them announcing a new executive order just signed that significantly expands our authorities to target individuals companies for there to institutions that finance and facilitate trade with north korea. he was flanked by the leaders of the two

countries most at risk from north korea the prime minister of japan and the president of south korea not present the nation which will probably be most affected by the new sanctions china but it appears there was some coordination before this move was taken china their central bank has told their other banks it's a massive banking system to immediately stop doing business with north korea in his speech to the general assembly china's foreign minister wang ye made no mention of that and again stressed dialogue was the only way to solve the crisis so if you want to. we urge the d.p. r. k. not to continue in this dangerous direction we call upon the u.s. to honor its former commitment and we call upon all parties to play a constructive role in easing tensions there is still hope for peace and we must

not give up negotiation is the only way out which deserves every effort. in a special security council session on nuclear weapons the us secretary of state rex tillerson cited south africa. and ukraine as examples of countries that have thrived after giving up the bomb parts in its official statements north korea often quotes another example libya gave up its nuclear and chemical weapons program in two thousand and three eight years later its leader colonel gadhafi was toppled with the help of the u.s. and its allies james. at the united nations the prime minister of bangladesh has made a plea to the united nations to help the range of refugees return home to me and shake a scene or call for the un and the international community to take action to stop what she called ethnic cleansing i see no one safe zone set up in myanmar which the un would police she also wants a second general to conduct

the supremes court in boston lona. the trigger was the arrested of more than a dozen cattle and government officials are directly responsible for the going izing the referendum. that prompted some older demonstrators here to draw parallels to general franco's dictatorship four decades ago this human to stop this franco style dictatorial regime must explode and we must set up a republic spain central government has vowed to shut down what it declares is an illegal referendum so protesters brought along their own card for ballot boxes. others printed their own voting slips with the kind of potato you know radio earlier spanish security forces confiscated more than ten million ballot papers that were. in there were none of the way or.

picking up strength as it makes its way across the caribbean puerto rico both the brunt of maria on thursday residents are now returning to find extensive damage to their houses. and north korea's foreign minister says his country is considering a hydrogen bomb test in the pacific ocean comes after president donald trump impose new sanctions on pyongyang on top of those already approved by the un the e.u. and china are also stepping up measures against pyongyang over its nuclear program . well hydrogen bomb tests were once commonplace but they felt to be ended more than fifty years ago h. bombs are much more powerful than atomic bombs for example north korea's underground test earlier this month was ten times stronger than its previous nuclear tests the u.s. and u.k. tested bombs in the pacific in the one nine hundred fifty s. france followed suit in the early one nine hundred sixty s. but then in thousand one. in sixty three nuclear treaty banning tests in a sea atmosphere and in space only underground tests were permitted more than

a hundred states are signatories to the treaty but notably north korea is not part of it let's talk to aiden bernese the former dean of science at the australian national university he's now with the university of queensland and joins me from brisbane via skype i mean how worrying is this announcement by north korea that it could carry out an h. bomb test in the pacific and why would they choose the perspective to the pacific where one of the reasons that we choose the pacific it's a little bit off their land mass and if you look at where most of the h. bomb tests have been to date a number of countries have tasted the weapons in the pacific just just talk us briefly through why a hydrogen bomb is so powerful and how does fission or fusion come into play here so with nuclear weapons there are two ways of getting the energy the first one is that in the the fusion bombs which were the first bombs and in those fusion bombs at the fission bombs you have. any material that you can energize so that the

ukrainian splits apart it releases energy and this releases an enormous amount of energy the hydrogen bomb is crisis we're as well as having that crisis you have another crisis which the fusion prices where you take light isotopes of hydrogen and i think used together to make helium and in that process they release more energy so what you have is each of these a two stage we're in where you've got the the normal nuclear weapon if you like with a blanket of extra energy around it so these bombs are considerably more powerful and is this sort of test able likely to be under water or an air burst over the water what's the difference between the two. well again that makes very little difference with a weapon of this size it really doesn't matter whether it's near the surface on the surface or under the surface now you know if it's deep underground the radioactive material that gets released is contained but actually if it's on the surface or about the surface very little difference what about the danger of radiation fallout

. if that they split and stays things the signature event tasting extremes around the world that the radiation levels when you dismiss it around the globe the very life that we we still see signatures of the weapons tests that happened in the fifty's in the pacific. thanks very much indeed for your time there john. mexico's search and rescue operation is focusing on ten buildings where authorities have to find people who survived tuesday's seven point one magnitude quake at least two hundred seventy three people died when buildings collapsed and two thousand more engine alan fischer visited the town of one of the most damaged by the quake. market traders felt she had to be here as they pulled apart the place she's called home for more than fifty years. so badly damaged in tuesday's earthquake the building was in such a dangerous condition she could recover anything but a previous life. is what she wears. i've lived here more than fifty years

it's terrible i can find no comfort i keep crying i have not eaten it just feels like a nightmare i i just can't. return center of all who didn't fare well in the tremor and just moments buildings which it stood for decades were gone others badly damaged. some people managed to grab what they could others could only watch as diggers pulled apart the remains of ordinary lives changed forever this street which is just reopened gives you an idea of the random nature of the damage caused by earthquakes this house here very little damage a few bricks missing above the galley door but just next door you can see gaping holes in the walls all the way up to the roof a lot of the frontage has fallen into the street the damage here is so bad that this house will probably have to be pulled down. on the edge of the turn they set up a camp for those who have nowhere to go to try to make it comfortable but you wouldn't call home. everyone works together to fill the trucks that regularly pool and this

takes the two duis and turns further away and those who simply won't leave home. didn't know what to do when the quake hit she's due to give birth any day for the moment that has to be the priority. they helped me with some for me. some diapers and clothes for my baby we left our house with nothing we barely managed to grab important documents i'm afraid to return home it's badly damaged. but turn of a who will rebuild in some ways that's an easy fix and years to come the only scars will be those in the hearts and minds of people who've lost everything alan fischer al-jazeera. mexico the united nations has added its voice to the growing opposition to a controversial referendum in iraq's kurdistan it says the vote planned for monday could destabilize the region so if god demands to call off the poll on independence have not been heeded hundreds turned out for pro independence rally in abilene iraq

central government has dismissed the vote is illegal the code is delegation said to visit baghdad on saturday to discuss possible alternatives facebook c.e.o. mark zuckerberg plans to share information about russian linked adverts with the us congress according to facebook some three thousand political ads organized by operatives based in russia ran on the site before last year's presidential election we are actively working with the u.s. government on its ongoing investigations into russian interference we've been investigating this for many months now and for a while we had found no evidence of fake accounts link to russian going to russia running ads and when we recently uncovered this activity we provided that information to the special counsel we also briefed congress and this morning i directed our team to provide the ads we've found to congress as well now as a general rule we're going to be limited in what we can discuss publicly about ongoing law enforcement investigations so we may not always be able to share all of

our findings publicly but we support congress in deciding how to best use this information to inform the public and we expect the government to publish its findings when their investigation is complete our white house correspondent kimberly hellcat has more. facebook has announced that it will continue to work with the u.s. government as it continues its probe into russian meddling in election interference it will also continue its own investigation and will be cooperate in sharing the information results of those investigations but it's also taking other steps to to ensure election integrity and to ensure that facebook increases its enforcement in terms of ads that are purchased just closing where those ads came from who paid for them and what their political motivations might be it is going to try and increase transparency and security and share that information with even compact heating tech companies or competitors as well to facebook c.e.o.

mark zuckerberg has announced that it hopes to increase is partnerships with election commissions around the world and increase the effort to get out the vote the goal dr burke says is to not only be a force for good but also to make sure that the elections around the world not just in the united states are free and fair. the kenyan president says a court ruling that an old his election victory last month is a coup and warn that it could throw the country into judicial chaos who are kenyatta says the supreme court has stolen democracy from the people the election board says there will be a rerun of the presidential election on october twenty sixth plain as the electoral commission for its decision to cancel the results saying the poll was not a transparent nor verifiable. by admitting they've got to get a for a little like kenya what has really happened in our country is nothing short of what kenya has so successfully managed to avoid over the last fifty years or so of our independent that has happened in many other countries where we have seen

military coups overthrowing civilian government but today we have broken our history with a coup in the republic of kenya that has been done by four people in the courts this is a coup and i must call it what it is and i would never be afraid to say that the un is worried that an election planned for next year in south sudan could lead to more violence in the region is calling for a dormant peace process to be revitalized before the vote is held even morgan reports in the northeast. she's lost her children and fled her village with her grandchildren now and you will says she doesn't hold much hope of getting to bury them she says government soldiers attacked her village forcing her to leave. i used to live in new i but got displaced by the army when they came to our area and attacked our village that killed so many people including my children and the father. is one of thousands of civilians who have been displaced in the past few

months of the conflict south sudan has been at war for much of its time since it gained independence in twenty eleven fighting between government and opposition rebels in the past few months has forced many south sudanese from their homes several have ended up here in a couple one of the last few areas controlled by opposition rebels led by the former vice president riek machar but there are problems here too including shortages of food and medicine many rely on fishing but the conflict has made it hard for them to access parts of the river. if there are areas where the government soldiers and i get close to them i stay hidden and drew away so they don't see me if they see me then it's a problem for me a problem made worse by the large number of people who have fled to this region at least twenty five thousand people have lost their homes since april because of fighting between government and opposition forces some of those displaced have crossed the border into if you add into the refugee crisis described as the fastest

growing in the world a quarter of the country's twelve million population is now displaced and the u.n. says seven point six million are in need of aid but delivering that aid has challenges we do have into what we call localized from him so actually the from is not widespread but actually has been it has affected actually particular areas of the country of course being one of the american arses is one of the main issues with everything starts with on not only not go but overall in the country as fighting and displacement continues and despite warnings from the international community and the u.n. south sudan's government has announced it plans to hold a presidential election next year as part of the twenty fifteen peace deal it's fine with the opposition we are implementing that demand as it came when i went in for i mean you got and they are you and the u.n. security council to tell us what do we do for them yes. for as we say we are going for elections but for many thousands who have been displaced like nubile the

mainstream making it seem more acceptable he tried to clean clean up its extreme image he tried to shift the focus away from issues like immigration and more on things like sovereignty and protectionism but when the pen lost the election many in the party turned around and said it was his fault that he simply had the wrong strategy and that he had. the base supporters what will happen to the national front now remains to be seen by many though all wondering whether or not it will actually slide back to its more halid right origins. of the top stories here on al-jazeera north korea's foreign minister says his country is considering a hydrogen bomb test in the pacific ocean it follows new sanctions imposed by u.s. president donald trump the european union and china are also stepping up measures against pyongyang over its nuclear program the prime minister of bangladesh has
