　　Hello, I'm Jonathan Izard with the BBC News.

　　Eurozone leaders are still locked in talks at anemergency summit, trying to find a compromisethat would enable Greece to avoid running out ofmoney and to keep the single currency. The GreekPrime Minister, Alexis Tsipras, is anxious to strike a deal before any Greek banks collapse,which could happen within days. Our economics editor, Robert Peston, who's in Athens, saysthe crisis is having a huge impact on the Eurozone itself.

　　"We have the spectacle this weekend of the two most important Eurozone countries, Germanyand France, at loggerheads over the future of Greece. And that, I think, has done damage allover the world to the idea that the Eurozone is a stable, collected enterprise by Europe'sleading economies. And I think that we will be paying a price for this crisis in the wider Europeanunion     for weeks, months, possibly, years to come."

　　The Mexican President, Enrique Pena Nieto, says he has faith that his security forces willrecapture one of the world's most powerful drug lords, Joaquin Guzman, who's escaped from ahigh-security prison. Here's Katy Watson.

　　"Joaquin Guzman was last seen in the prison showers on Saturday evening. When guardschecked his cell later, he disappeared. They found a hole, ten metres deep, with a ladderleading to a tunnel, a kilometre and a half long. According to security officials, it had lighting,ventilation and stairs. For a government, which, in recent years, has boasted of its record ofcatching big drugs lords, this latest escape is particularly embarrassing, because it's the secondtime Guzman has got away."

　　The Colombian government has issued a joint statement with FARC rebels, agreeing todeescalate the conflict between them. Government forces will pull back from military action in aweek's time, if the rebels keep their promise of a unilateral ceasefire. It's the first suchagreement since peace talks began in Cuba in 2012.

　　Representatives of six world powers and Iran meeting in Vienna are reported to be close to adeal over Tehran's nuclear programme, with an announcement possible on Monday. The dealwould give Iran relief from many international sanctions in return for observing strict limits onits nuclear programme. Jon Sopel is in Washington.

　　"One senior administration official, who's been very close to these talks, said a perfect deal isvery easy to sell. One, where Tehran walks in, waves a white flag and offers endlessconcessions, is very easy to sell. A good deal, which has been forged out of compromise,concession and mind-boggling, complex details, very much more so. The Obamaadministration wants to say this is a good deal, and better than no deal at all. His opponentsthink otherwise, and they are making the running at the moment."

　　At least two car bombs have gone off and a suicide bomber has blown himself up in the Iraqicapital, Baghdad. More than twenty-eight people were killed, and eighty injured in mainly-Shiiteneighbourhoods. No one has claimed responsibility.

　　Video footage has emerged in Israel, allegedly showing a senior Israeli officer, shooting dead afleeing Palestinian teenager, who had thrown a rock at his vehicle last week. The video, releasedby a human rights group, contradicts earlier claims by the military that the officer opened firebecause his life was in danger and that he had exhausted all measures before shooting theteenager. The Israeli military has declined to comment.

　　A bomb explosion in the Syrian city of Aleppo has caused part of the wall of its ancient citadelto collapse. The magnificent Thirteenth-century citadel, with its ramparts and towers, is a U.N.-listed World Heritage Site. Rami Jouer, a Syrian activist, told the BBC that the people'srelationship with the monument was changing.

　　"The citadel, at the moment, stands as a launching point for the Syrian military. And it'ssurrounded by rebel-controlled areas that continues to be attacked by the regime. So it's nolonger looked at as a historic site, but rather a military site. That's what makes this incidentsignificant. It's that there is now an advance within the old city."

　　Hundreds of thousands of people in Paraguay have attended the final mass celebrated by PopeFrancis during his visit to South America. The Pope urged Christians to reject, what he called,the logic of selfishness. During his previous stops in Bolivia and Ecuador, the Pope spoke outagainst social injustice. He leaves Paraguay on Monday after an eight-day tour.
