So many hours of talks, so little progress. Despite two days of intensive negotiations, Iran and six world powers "remain far apart" on Tehran's controversial nuclear program, EU foreign policy chief Catherine Ashton said Saturday in Kazakhstan. Her words dashed hopes that the deadlock might be broken after what had seemed more promising talks back in February, also in the Kazakh city of Almaty. Iran's top nuclear negotiator, Saeed Jalili, acknowledged there was "some distance" between Iran and the six powers but seemed more positive in his assessment. "Good negotiations" had taken place in this round of talks, Jalili said, which he described as "substantive, expansive and comprehensive." But in a sign that progress was limited, no date or location has been set for new talks. This round was just the latest in a decade-long attempt to resolve differences between Iran and the international community over Tehran's nuclear ambitions. The first day of talks proved inconclusive. By the end of Saturday, despite "long and intensive discussions," the two sides were no closer on agreeing on confidence-building measures, Ashton told reporters. "It became clear that the positions of (the world powers) and Iran remain far apart on the substance," she said. "We therefore agreed all sides will go back to their capitals to evaluate where we stand on the process." Ashton said she would be in touch with Jalili "very soon in order to see how to go forward." While Ashton said these were the most detailed discussions that the two sides had had, with "a real back-and-forward between us," she also made clear that she was disappointed by the lack of progress made. A senior U.S. administration official said Jalili directly engaged him in a 30- to 40-minute question-and-answer exchange in the middle of Saturday's plenary meeting. "The quality of the discussion was different because there was this back and forth, this Q and A," the official said. "We just went back and forth with him." Still, the official expressed disappointment, saying that Iran had "put forward some minimal ideas and expected great return, and quite disproportionate return." Britain, too, took a hard line after the talks. "The UK went to Kazakhstan ready with our partners to negotiate in good faith with Iran," British Foreign Secretary William Hague said in a statement. "Iran's current position falls far short of what is needed to achieve a diplomatic breakthrough." When negotiators from the diplomatic bloc of six nations -- the United States, France, Britain, Germany, China and Russia -- last sat down with Iran's envoy in Almaty in February, they delivered what they characterized as a "fair and balanced offer" to defuse tensions over the Iranian nuclear program. Instead of delivering the "concrete response" Western governments had expected, Iran announced it was making its own proposal to the negotiating parties. 'Two-way street' Jalili said Iran had tabled a proposal based on the discussions in Almaty and a previous meeting in Moscow -- and that it is now down to the six world powers to respond and show their "willingness to take appropriate confidence-building steps in the future." He repeated Tehran's position that Iran has the right to a peaceful nuclear program. "Creating confidence is a two-way street," he said. Now, after many proposals put forward by Iran, it's the turn of the six world powers to respond, he said. Jalili's comments on Iran's enrichment of uranium -- one of the most contentious issues at stake -- reaffirmed Tehran's right to pursue that track but also appeared to leave the door open to some kind of negotiation. "Enrichment is part of the rights of the Iranian people, whether we're talking about 5% or 20% ... however, this can be an issue that can create further confidence," he said. Jalili added that "hostile behaviors" directed toward Iran were detrimental to building confidence. This was presumably a reference to the draconian sanctions imposed by Western governments against Tehran, which are crippling the Iranian economy. Oil exports have plummeted over the past several years, as has the value of Iran's currency. "The purpose of any sanctions is to put pressure in order to get this process to work," said Ashton. "And I believe we should continue to work as hard as we possibly can to make sure we are successful and we reach a satisfactory resolution." Questions fly around any plan to attack Iran . The so-called P5+1 governments are demanding that Iran come clean about its nuclear program, which they suspect includes covert development of nuclear weapons. Iran consistently denies those charges, arguing it is enriching uranium and building nuclear reactors only for peaceful civilian energy needs. Details of last February's offer from the six countries represented across the negotiating table from Iran have not yet been made public. Last month, technical experts from Iran and the P5+1 countries met for more than 12 hours in Istanbul to discuss the proposal. Iran's deputy chief negotiator said the Iranian proposal tabled Friday was based on a previous PowerPoint presentation that the Iranian delegation submitted during a round of talks in Moscow in June 2012. "The Islamic Republic of Iran proposed a practical method to implement the Moscow plan in a smaller scale," Ali Baghery said in a statement issued to journalists Friday. The offer, he said, was aimed at establishing "a new bedrock of cooperation." A call for 'concrete actions' Washington has vowed it will continue to put pressure on Tehran. "As long as Iran does not take concrete steps to address the concerns of the international community about its nuclear program, the dual-track process continues. And that pressure only will increase if Iran does not begin to take concrete steps and concrete actions," said a senior U.S. administration official in a telephone briefing to journalists this week. The official spoke on condition of anonymity. Iran argues that as a signatory to the Nuclear Non-Proliferation Treaty, development of nuclear technology is an inalienable right. On the eve of the two-day talks in Kazakhstan, Jalili repeated this position in a speech given at a university in Almaty. "It is the right of the Iranian people to peaceful nuclear energy and most importantly to enrichment," Jalili said. A report recently published by the Carnegie Endowment for International Peace concluded that sanctions are unlikely to force Tehran to give up its nuclear program. The report, titled "Iran's Nuclear Odyssey," highlighted the fact that Tehran's quest for a nuclear program has been going on for more than half a century, beginning under the rule of the pro-American shah, Reza Pahlavi, and continuing under the revolutionary Islamic republic that overthrew him. "The program's cost -- measured in lost foreign investment and oil revenue -- has been well over $100 billion," Carnegie said.

On canvas, Vladimir Putin appears stern, Tony Blair looks relaxed and Junichiro Koizumi smiles broadly. Through paint and brushstroke, former President George W. Bush says he has found not only a rewarding hobby but a unique way to express himself and his impressions of 30 presidents, prime ministers and other world leaders during his time in office. These never-before-seen portraits, which were done by looking at photographs, will go on public display Saturday at his presidential library in Dallas. The exhibit is titled "The Art of Leadership: A President's Personal Diplomacy." It will also include photographs and artifacts of his interactions with these leaders. "I think they're going to be (like), 'Wow, George Bush is a painter,"' Bush told NBC's "Today" show in an interview on Friday. "I'm sure when they heard I was painting, (they said), 'Wow, I look forward to seeing a stick figure he painted of me.'" One work he is most proud of is that of his father, former President George H.W. Bush. "I painted a gentle soul," he said. The Bush Presidential Center is using these paintings to help broaden the image of Bush and is hoping to show "what it takes to be a personal diplomat," said Margaret Spellings, president of the center, emphasizing one-on-one relationships with his fellow heads of state were very important to him. Most of the world leaders portrayed have not seen the art yet. George W. Bush to unveil paintings . The rebirth of cool . For newer generations the artwork, and the buzz around them, will show a new side of Bush. The 43rd President has enjoyed a resurgence of popularity, a bump aided partly by his work trying to save the lives of Africans who have AIDS and efforts to help veterans, including helping them to find jobs. Forty-nine percent viewed him favorably while 46% saw him unfavorably according to a poll last June from Gallup. When Bush left office in 2009, only 40% of Americans held a favorable opinion of him, a number which sunk to 35% in March of that year before beginning a slow climb out from under water. He's also earned nods from such publications as BuzzFeed and Vanity Fair that noted his counterculture hipness in painting outside of the art establishment  and taking selfies. Though the former President has opened a new chapter of his life with painting, there were reminders of the controversies surrounding his presidency. Just this week, the Senate Intelligence Committee voted to seek declassification of its report on the secret prisons and interrogation techniques used by his administration on terror suspects after the September 11, 2001, attacks. Bush also has refused to publicly discuss politics. In a video accompanying the exhibit, he said of the Dalai Lama: "I painted him as sweetly as I could." For Blair, the former British Prime Minister and one of the leaders he spent the most time with, Bush said he painted "with a lot of affection" and was trying to convey "a passionate person and a reliable person." After reading an essay about Winston Churchill's art hobby, Bush took up painting two years ago. "I gave it a whirl," he said in the video. He hopes the paintings help convey his feelings and friendships to these leaders. He told NBC this will help "make sure the last chapters of my life are full." Opinion: Bush paints, but is he any good? "I want to get better" Bush said he still has a lot to learn with this hobby. "I am not a great artist," he told his daughter Jenna Bush Hager, who is a "Today" show correspondent, in the NBC interview.  "I paint a lot. I want to get better." He has his share of critics. New York Magazine Art critic Jerry Salz said of some of Bush's previous  artwork "no natural giftsâ€”except the desire to do this." Bush's family said he is very disciplined and dedicated to his work and will often spend hours in his new studio with music playing. Family and friends said he is very excited about his work. "He talks enthusiastically about it," Spellings said. Bush "utterly loves it." Bush uses various photos to see facial expressions, clothing and other attributes that he then uses to craft his paintings. He started off doing some smaller things like animals. Then an art professor at a local university suggested he try doing world leaders because he was good at capturing details. He was initially reluctant to share his work publicly. However, his paintings first came to light after a hacker last year obtained private Bush family emails, which included photos of some of his work. Some of the other paintings featured dogs. But other paintings were self-portraits of him in the shower and the bathtub while he was looking in a mirror. "It's an invasion of one's privacy. And yeah, I was annoyed," Bush told NBC. "And nor do I want my paintings to get out. And I found it very interesting the first painting that came out was the one I painted of myself in the bathtub. I did so because I wanted to kind of shock my instructor." Bush on painting: 'I see colors differently'

(CNN) -- Men sprawled on a tile floor, shirtless and convulsing. Children, too, seemingly unable to control their shaking and flailing. Panic and screams in the background. These are some of the hard-to-stomach images that the Obama administration has shown a select group of senators in closed-door briefings to make the case that a limited military attack on Syria is justified. CNN was the first to obtain the 13 different videos seen by members of the Senate Intelligence Committee that depict the gruesome scene of an chemical weapons attack in Syria on August 21. The administration told senators that their authenticity was verified by the intelligence community. The attack, allegedly carried out by Syrian forces under President Bashar al-Assad, has touched off the most critical foreign policy question since the uprising began in 2011: Is a military response merited? The videos capture a moment of panic, as those who are standing try to feed water to those who appear incapacitated. Prayers are repeated. What is sarin? Many of the videos were previously posted on YouTube, but this collection of footage is significant because the intelligence community has given it a stamp of authenticity. The footage could be vital in the administration's quest to convince Congress and the American public that the U.S. must launch punitive strikes against Syria, former U.N. Ambassador Bill Richardson said. "That video will sensitize the American people that this isn't just an intervention, that this is a military strike to stop that type of atrocity," the former congressman told CNN. While the videos are hard to watch, they do not prove who is responsible for the attack, nor do they provide an answer for whether military strikes are the correct course. President Barack Obama favors limited intervention, and his administration has been working nonstop to convince allies in Europe and lawmakers back home for support. Hours after CNN obtained and broadcast portions of the videos, the Senate Intelligence Committee posted them on its website for public viewing. An aide to Dianne Feinstein, the committee's chairwoman, said it's expected the video will be played Monday at a briefing for all House members. Secretary of State John Kerry, Defense Secretary Chuck Hagel and National Security Adviser Susan Rice will be among those representing the Obama administration at that hearing and one Wednesday for senators, according to the White House. Based on her attendance at closed-door briefings, Feinstein has decided to vote in favor of the measure to intervene militarily in Syria, defying the wishes of many of her constituents. "What's coming in is overwhelmingly negative," Feinstein said Thursday about the feedback from voters. "There's no question about that. But you see, then they don't know what I know." The availability of these videos obtained by CNN means that anyone can see at least part of the administration's evidence and come to their own conclusions. One video shows a room with enough children to fill a classroom, but they are arranged on the ground, the bright colors of their shirts -- red, yellow, green, purple, blue -- contrasting the paleness of their dead bodies. There were dead adults placed in this space, too. The video captures at least six rows of adults with no less than four bodies each. Sheets and blankets cover some of the bodies. In another video, a man uses a manual resuscitator on a toddler, who appears motionless. Another man comes with a bottled water and the men together try to rinse the small boy's face. It looks like the boy's chest moves, but his arms remain pinned to his side like a soldier at attention. CNN cannot independently confirm the authenticity of the videos. But officials have a number of reasons as to why they believe they are authentic. The videos were shot from multiple angles, providing overlap, not just in what could be seen but what could be heard, the administration officials told the senators. Why use chemical weapons? CNN's Ted Barrett contributed to this report.
