(CNN)Floods displaced more than 150,000 people in Argentina, Brazil, Uruguay and Paraguay this week after days of torrential rains blamed on El Niño. In Paraguay, which was the hardest-hit, more than 130,000 people were evacuated. In Alberdi city, residents fled as walls holding back water appeared on the verge of collapse, authorities said. Argentina had 20,000 evacuees, half of them from Concordia city, which President Mauricio Macri will visit Sunday. http://www.cnn.com/2015/12/27/americas/south-america-flooding/
