World leaders have been unable to stop the conflict in syria. Now theyre trying to help the victims. In a Conference Today they pledged more than 10 Million Dollars to syrians. That will provide food, water and medicine as well as jobs and schools. Our correspondent is in london with more reporter the u. N. Calls it the worst humanitarian crisis since the Second World War and it is very difficult to see how it is going to end. The failure of talks in geneva made it this gathering this gathering all the more important. The suggestion inside syria is as close to hell as we are likely to find on this earth. If we are to stop the most able and qualified syrians from leaving their country, they need confidence that they can do more than just survive. Reporter there is a depressing assumption behind this conference, that the Syrian Crisis will be with us for some time to come and, therefore, donors need to look at longterm assistance, education and employment for millions of syrians in the long years before they can return home. From turkey, lebanon and jordan, stark warnings. They cannot carry on looking after millions of syrians without more assistance. Reporter looking into the eyes of my people, and seeing the hardship and distress they carry, i must tell you we have reached our limit. I represent the people of jordan, their wellbeing and safety are my first priority. Our country will continue to do what we can do to help those in need but it cannot be at the expense of our own peoples welfare reporter donors give more aid to syrias maybes and in return they open up labor markets and ensure more syrian children go to school, but as the norweigian told me in pointed remarks about one of the participants in the syrian war, the real solution is peace. The need to have confidencebuilding measures in syria, that means the fighting has to decrease. Russia has to take the responsibility to make sure that there is a possibility for this peace negotiation and it should be in their interests too. I dont think russia would like to stay on forever with military personnel and an expensive war in syria. Reporter but European Countries in particular have their own reasons to give generously here, by making life tolerable for the region but perhaps less likely to see the issue. It is hard to believe it will be a lasting solution any closer the number of Syrian Refugees continued to surge. 70,000 people have fled from aleppo in recent days. Many are immediated towards the border. Reporter many have fled their home in the countryside of aleppo as a result of the government advance in the area as well as the intense russian bombardment. Pictures have emerged of hundreds of people, the turkish borrowed. We do not understand how many people have been displaced. According to the organization that monitors the situation on the ground, up to 40,000 people have fled their homes over the past time. Thousands are heading to the Turkish Border and the people are appealing for help. We have lost families, and some are saying that this is not the first time, and one man said that he was first displaced from the central city, and he moved north and had to move from town to town, and he finds himself on the Turkish Border and these people are appealing to the authorities to open the border. Turkey has an open dor policy, but over the last year, restrictions have been imposed. One is for security. And the other is that turkey hosts up to 2. 5 million refugees, and it has been a lot of burden on the turkish authority. Aside aside says that its prepared to send Ground Troops to syria to fight isil. But only if asked. Its the first time that they have been willing to take part. They already belong to the coalition, launching airstrikes against the group. Saying that they will shoot a satellite into orbit. This week, defense secretary ashe carter cited it as number three of the top five threats against the United States. Calling the north Korean Missile technology, he didnt have any plan on what to do about it, but calling for what he called incredibly strong. This is a far cry from what ashe carter suggested a decade ago when h he was not at the pentagon. North korea has launched missiles before in 2019, and a less successful attempt three years earlier, and back in 2006, ashe carter knew how to respond to the threat. Take it out with a Cruise Missile while it was still on the launch pad. Along with his mentor, defense secretary william perry, carter argued forcefully that the United States should immediately make clear its intention to strike the north Korean Missile before it can be launched. He added that the multistory thin skinned missile is itself explosive, and it would cause it to explode. But late last time year h. I asked carter about the wisdom of a preemptive strike against a volatile regime, he made it clear that its not something that he wanted to revisit. A few years ago, when you were in office, secretary perry advocated that the north Korean Missile be taken out on the launch pad before they could test it. Are a you thinking about that change . Where we are on that, we always are discerned about north korean behavior, and provocations of all kind. When i pressed him, carter gave it to another reporter. When you argue about the preemptive strike, you argued very convincingly. Reporter but this week, as he rolled out the pentagon budget, carter faced the question again, and his answer. That was a different circumstance then, and it was of a test missile, and our policy was that we were not to tolerate it. And we were trying to figure out how to not tolerate t that was then, and this is now. Reporter but then is now, and north korea was still seeking to put a nuclear warhead, small enough to put atop a longrange missile that would reach the United States, and carter argued that a preemptive strike would carry little risk, arguing that they could take the drastic step of the korean peninsula, but its not likely to act on that threat of the its a threat that secretary carter is not so quick to dismiss. I have to remind you, war on the peninsula, its a very savage and intense war. Carter is second in the chain of command, hes privy to estimates of war on the peninsula, and it could result in 1 million casualties, and the destruction of the south korean capital of seoul. Its different than ten years ago, carter was an unsolis i wanted outsider whose advice could be easily ignored. And now hes in a place of responsibility where talk of war risks real lives, and es speculation could mean disaster. Martin scorelli was on capitol hill today talking about pharmaceutical price gouging. Hes bestknown for buying a drug to treat disease, and hiking the price. And this scorelli character, he didnt have much to say today, de . No, he didnt, toney, and members of the Oversight Committee learned very little. He repeatedly invoked his 5th amendment right to avoid self incrimination, and his silence only made the Committee Members angrier, both at him and what he represents, and also this issue of drug pricein jacking up the price from 13. 50 to 750 a pill. You say that the pregnant woman who might have aids, although income, she needsdera prim in order to survive, and what do you say to her . I respectfully decline your question. It was one that skreli applied to over and over. Do you think that youve done anything wrong . Apply 5th amendment privilege and respectfully decline to answer your question. Asked why he would be an advocate. You can go down in history against drug companies, or change the system. Drug companies and the system we have today. And i truly believe, i truly believe are you listening . Yeah i truly believe that you can be for g. Well pause while mr. Shkreli is escorted out. I dont think that ive ever seen the committee treated with such contempt. Shkreli was quiet in the hearing, but took to twitter afterwards to mock Committee Members. Writing, these imbeciles represent our government. And his lawyers talk to him. Mr. Shkreli will realize that he has saved many many lives by his brilliance. Reporter but shkreli at thursday mornings hearing didnt win him any fans in congress. Shkreli is called pharma bro for his young age, and also for his active social media presence, and the attitude that he has with members of congress, they got what they expected today. But to dig into the substance of this very real question, what its doing, and the oversight included documents from shkreli, talking about what huge profits the company will make jacking up the price of dara prim. And were talking about 750 a pill. And 150 pills cost you 175,000. Thats quite a performance from mr. Screli, libby casei, thank you. A United Nations group, arbitrary detention, hes being dapped. And that doesnt mean that he will not be able to leave. Julian asan is holed up inside of the ecuadorian embassy. Asan filed a complaint to the u. N. In 2014, claiming that his state is effectively a detention, saying that if he tries to leave, he faces immediate arrest. Had from assanges lawyer. He has been detained for 3 and a half years by sweden, then i see no way out for this for freedom, and to prosecute him. To detain assange and to close the case. Reporter the swedish government said that it disagrees, and so does too the uk. Its unclear what difference the u. N. Meetings are likely to have on the british government, saying that this is an unlawful detention, but instead a volunteer decision to evade arrest by the ecuadorians. And they said that they are obliged to extradite him because of allegations of rape. He believes that he will be handed over to washington if hes sent to sweden. And he faces questioning, only by the embassy and by ecuadorian prosecutors. Thousands of secret documents on it, exposing classified and often embarrassing details about the world governments. Assange always said that he would leave the embassy if he lost appeal. And now hes trying to go to ecuador, where hes granted asylum. But the police say that they will make everiest to arrest him. Aljazeera, the ecuadorian embassy, london. Hilliary clinton and Bernie Sanders will debate in New Hampshire tonight, ahead of tuesdays primary. And aljazeeras lisa stark joins us at the university of New Hampshire, and lisa, how would you describe it at this point . I heard the word combative used. Reporter i would say increasingly contentious, and you know, tony, this is the 5th democratic debate, but its the first with just hilliary clinton and Bernie Sanders onstage. Martin omalley dropped out after iowa, and it will be just the two, and well see how that changes the dynamics, and as the candidates are preparing for the debate, and they have a lot of them skelled for next week, their campaigns have been marked for thousandsiches volunteers to help get out the vote next tugs. Im a volunteer for hillary. We need somebody like bernie. These are the campaign Ground Troops. I hope that youll vote for hillary. Reporter the army of paid staffers who have one mission. Theyre working the phones and going doortodoor to roundup supporters. We went to the Bernie Sanders field office in manchester, one of 18 in the state. And hilliary clintons office, one of 16 campaign centers here. With just days before the primary, theyre buzzing. Clinton has 10,000 volunteers here. She has pulled them in from all over, including 150 who trekked from the new york office for this final week. I really really want her to be president. 22yearold lauren crep has put her life on hold to volunteer for hillary. College student, melissa robins, who came onboard just in time for iowa. My nails are gone. They were gone the night of iowa. But its exciting to watch, everyone coming together for a common goal. And im so excited for the primary. Im incredibly excited. I love watching them, its like watching the super bowl to me. Reporter sanders has fewer volunteers working the state. About 7,000. One is halfway around the world, and he cant even vote here. Im from australia reporter Michael Quincy oneil is heading back, mostly paying out of his own pocket. I think bernie is a great canceled date and i want to see him win the white house because u. S. Policy influences australian politics. Hello reporter this is how most voters see the candidates, but researchers say that behind the scene efforts can make a difference, most effective, knocking on doors, but phonecalls too. Phonecalls and voters what time are you going to the polls . And they feel obligated to follow through. Hi, im a volunteer for the Bernie Sanders campaign. Reporter working off voter lists, here florida, theyre spending up to eight hours a day to convince others on the other end of the line first to not happening up, but second, to vote for sanders. When you get that one that commits, everything is worth it. If we can influence one person, i feel like ive done my job reporter a vote in the bag. And in clintons, a 95yearold who wants to attend her inauguration. That would be wonderful. I hope that we get to see her, the first female president. Reporter cathy nutter has been a long time hilliary clinton supporter. Eight years ago in the general election, she wrote in clintons name, rather than vote for obama. I had to vote my conviction, and she represented me more than i felt was any other candidate. Politics is a big thing in my family. Reporter to do this work takes perseverance, and in a few days, they will know whether it all paid off. And here in New Hampshire, sanders continues to lead in the polls. He has about an 18point lead over hilliary clinton. And nationwide, in fundraising, hes doing very well. For the first time, he has raised more than hilliary clinton. 20 million in january to her 15 million. Tony . Now, thats a significant development. So lisa, look. Theres a discussion on whether debates like tonight make a difference, but ill put the question to you. Could tonights debate make a difference there in New Hampshire . Well, as you know, sometimes there are pivotal moments in debates that can make a difference. Bernihillary is a seasoned debar and so is sanders, but a lot of voters dont make up their minds until the last minute, and until they have the gut feeling, and they hope to help some of them make up their mind. Still ahead, cheap oil, and the price that thousands of workers are having to pay across the united kingdom. As you know, oil prices have been taking a real hit since the summer of 2014, falling nearly 70 . Well, today the global bench mark fell nearly 2 to 32 a barrel. And some analysts are predicting that it could fall below 20, to even 10 a barrel if you can imagine that, europes largest oil company, shell is feeling the effects. Shell is cutting 10,000 jobs as it reported, the most in over a decade. Its not the only company in trouble. The north sea industry, bp has already announced that it will cut 10,000 jobs by the end of next year. Emma hayward is in aberdeen, scotland, where onethird of the workforce there is reliant on the oil industry. These rigs are redundant, waiting for the next job p. If it ever comes. With 30 years experience, kenneth little knows the feeling. He has dedicated his life to Scotlands Oil industry, but a few weeks ago, he was told that his contract with bp is finishing, his family is a casualty of the oil price slump. Because it costs so much less to fill up the car and fill up the oil tank and everything else. And people dont realize that most of that fuel coming down has an impact o on the job. They began pumping oil from beneath the north sea since the 70s, and it creates thousands of jobs across the uk. The discovery of oil out there in the north sea 40 years ago, has helped to bring in billions of dollars in revenue for the uk. And it changed the fortune of some living here. It has been felt both on and offshore. Further south, aberdeen, a city which became rich on black gold. Britons oil capital is suffering though, with jobs going more and more. The hotels are down and the taxi drivers business is hard. So its very real and very present at the moment, the impact on the industry. We soon found that there were many other place thats we could supply material to. This company has been supplying pipeline since the 70s, but theyre now diversified into new markets. Were looking at opportunities to grow our business, already in a more domestic market, and in the international sectors, but were focusing on nuclear, other areas that necessarily are not affected by oil pricing. Reporter here, the industry is entering uncharted waters. Believed to be about half as much oil left in the north sea than has already been extracted. But with a global oversupply of energy, it might be politics that determines the future of the industry in scotland. Aljazeera, on the northeast coast of scotland.
