A woman wearing a Guy Fawkes mask holds a sign which reads #Iam Guate(mala), #29 August, during a demonstration to demand the resignation of Guatemalan President Otto Perez in downtown Guatemala City, August 29, 2015. A Guatemalan congressional committee on Saturday recommended that Perez be stripped of immunity from prosecution over his suspected involvement in a customs racket, paving the way for a full vote in Congress in the coming days. Perez is accused of participating in a customs scam, known as La Linea, whereby importers avoided paying customs duties in exchange for bribes. He has denied the allegations and said that he will not resign. REUTERS/Jorge Dan Lopez
