A gas explosion in a residential area of Rosario, the third-largest city in Argentina, occurred on August 6, 2013. It was caused by a large gas leak; a nearby building collapsed, and others were at high risk of structural failure. Twenty-two people died, and sixty were injured. Several organizations helped secure the area, search for survivors and aid people who lost their homes. The provincial judiciary launched an investigation into the cause of the explosion, and particularly the role of Litoral Gas, the natural-gas provider for Rosario. President Cristina Fernández de Kirchner, who had recently returned from a diplomatic visit to the United Nations, visited the site of the explosion, and most of the candidates for the 2013 primary elections suspended their political campaigns. Pope Francis sent a letter of condolence to the Archbishop of Rosario that was read during a mass and procession for Saint Cajetan at Plaza 25 de Mayo, Rosario's civic center. (Full article...)
