Its obviously peace hasnt come. The explosions prove the deals been breached. I dont know who i can look to for hope when the toplevel agreements have failed. Unquestionably, it is the most intense bombardment in this region of the capital city since saturdays socalled cease fire. Fighting around donetsk, around the Southern City of mar apoll and in debaltseve. In debaltseve the rebels make their feelings plain about the ukrainian flag. Across the lines, ukrainians embracing, glad to be out of the hell that was debaltseve for them. They were shelling almost the entire town starting at night they would fire at us just to stop us from sleeping.

But german officials quickly rejected it, calling it a trojan horse for shirking its commitments and leaving too much open for interpretation. The german minister for Economic Affairs spoke in berlin. translated this offer is insufficient because it lacks all specific measures in greece. And that cannot happen. We cannot make it easier in greece on the shoulders of german and european tax payers. Over the next days, especially tomorrow, we need to negotiate further to find an agreement on specific measures.

And, the melodies and memories of opera singer Deborah Voigt. Woodruff president obama again warned today of the growing threat of extremism around the world at a white house sponsored conference, and urged the Global Community to do more to stop it. Responsibility to cut off funding that fuels hatred and corrupts young minds and endangerous us all. Woodruff the president shifts his focus woodruff the president shifted his focus overseas today, before an audience of ministers from around the world. He placed special emphasis on the role democracy plays in fighting terrorism, a theme often heard from his predecessor, george w. Bush. When dissent is silenced, it feeds violent extremism. It creates an environment that is ripe for terrorists to exploit. When peaceful Democratic Change is impossible, it feeds into the terrorist propaganda that idea that violence is the only answer available. Woodruff mr. Obama also urged leaders to expand human and religious rights as they confront extremist ideologies from groups like Islamic State. Also key fostering economic and Educational Opportunities for young people who may be receptive to the militants call. Delegates from 65 countries also heard from u. N. Secretary general, ban kimoon. We will never find our ways by discarding our moral compass. We need cool heads, we need common sense, and we must never let fear rule. Woodruff he pressed for alternatives to purely military responses. It is all about education education, education. Opportunity, opportunity opportunity. Empowerment, empowerment, empowerment. Woodruff jordans foreign minister nasser judah vowed his country will lead the fight against extremists, a role that has stepped up since the executionbyburning of a jordanian pilot by Islamic State. If anyone had any doubt the brutality and barbarism of these extremists, then this doubt has been removed. If anyone had any doubt that this is our war as muslims and our collective war as an international community, that doubt has been removed. Woodruff and as europe reels from a spike in homegrown terrorism and its own citizens leaving to join Islamic State and other groups, the French Interior minister highlighted the different pathways leading people toward extremism, including social media. translated the profile of terrorists and potential terrorists is very diversified now. Many have access to the internet and learning on the internet. They go abroad and they are trained to kill when they come back to europe. They go from criminality to terrorism. In prison, they have contact with extreme terrorists. Woodruff private meetings among the ministers were held throughout the day, as they search for a full spectrum response to a complex, bedeviling challenge. Earlier this afternoon, i sat down with the United Nations secretary general, ban kimoon while he was in washington mr. Secretary general, thank you for joining us. Its a great pleasure to see you, thank you. Woodruff so you are in washington for this summit on countering violent extremism. Compared to all the other threats in the world right now, where does this rank . We have been duesing about the consequences of terrorist acts. The purpose of this meeting is very important. In a sense that we have to address terrorism and violent extremism in a multidimensional way, starting from the root causes of political social economic and cultural aspects. This is a Global Challenge and, therefore, everybody should get involved with this. I am very encouraged president obama has initiated this white house summit meeting and this is the time for us to show our solidarity, at the same time build upon what we have been doing until now. Focusing on more preventative ways. Woodruff a lot of conversation today you brought up education, preventing terrorism, preventing young people from turning to terrorist activities. But what about where its already taken hold . What about in places in the middle east where groups like Islamic State i. S. I. S. Are already killing people taking over terrorist. Whats to be done there . For those barbaric acts we refer to as such. Many countries have shown such a strong solidarity even using military means. But military means may will b effective in some sense but thats not all the answers. We have to get at the root causes. Good governance is an answer and how to educate and how to send a message to many people and how to protect the human rights and dignity of marginalized people, how to make sure that the people are feeling some sense of belonging to their society. Woodruff would you say now violent extremism is the greatest threat to world stability . I believe so. We have seen so many crises regionally and National Conflicts but the translation is terrorism and extremism do not have borders, therefore it is a Global Challenge. If we dont address this, this will destroy the fabric of our community. Woodruff let me ask you about that because yes i. S. I. S. Is giving the Islamic State a lot of attention right now in the middle east and syria, but, in fact while that is happening, the regime of president assad is responsible for hundreds of thousands of deaths, 350 people died just in the last few days in damascus, over 100 of them women and children. Is it world giving president assad a free pass, turning the other way while it focuses on i. S. I. S. And not on him . No, we cannot and we will never give any free pass to anybody including president assad to kill their own people. Thats totally unacceptable. At the same time, we have to be very practical on how to resolve this issue. There is no alternative to political and inclusive dialogue a political solution. Thats what my special envoy has been really trying to resolve this issue, trying to have some political space, as much as possible. Woodruff but your point is president assad still has to go for there to be a solution in syria . That will have to be discussed in the final phase of political negotiations and by the people. Woodruff let me ask you about ukraine weve seen great advances by the pro russian rebels in a few days. Theyve taken over a key town. The british are providing photographic evidence the rebels are using advanced antiaircraft weapons system, the sa22. Is there any doubt that president putin and russia are very much behind what is going on in ukraine and by letting this happen, by the west not getting more involved, isnt this giving president putin a victory . Its not a matter of giving something a victory or not. The leaders germany frarntion ukraine and russiathe meeting was an encouraging one and urging the partys concern these are women, the political memorandum must be implemented in sincerity and totality. There is fighting still going on in donetsk and mariupol. Im urging them to abite by this agreement. Theres no way or alternative to the solution of this peaceful dialogue and negotiation. Woodruff meanwhile the british are saying just today that russian fighter jets were very close to british airspace, that the british officials are saying president putin is a real and present danger to europe, there is an e. U. Official that is saying mr. Putin is trying to redraw the boundaries of europe by force. Do you agree with that . President poroshenko of ukraine has announced that he will pull all the military armament and his forces and therefore deploy russians and the russian side shall pour out. The agreement of just a few days ago is a matter of integrity. Woodruff excuse me, but that doesnt look like its happening. Im urging as secretary general of the United Nations to abide strictly by this agreement. United nations has made clear that the United Nations will do all to provide the humanitarian assistance to those who have been affected and also continue the Human Rights Mission there. Woodruff but again, so many challenges facing the United Nations. Two of your former predecessors as secretary general have issued a letter saying that they feel strongly the United Nations needs to be reconfigured, it needs to be reformed in a way that the city council doesnt have the veto system that it does now, that its more transparent more democratic that the u. N. Isnt respected anymore by the people fighting on the ground or even member countries. Do they have a point that the u. N. Isnt respected and doesnt have the authority that it needs to have to make a difference . I think just to generalize what thations doing isnt helpful at this time. Thations not a perfect organization. There are many challenges. For us, there are some inefficiencies, but since i became secretary general, i have been trying to make the United Nations more relevant efficient, effective and more transparent. Woodruff secretary general of the United Nations we know there are a lot of challenges out there
