A demonstrator holds an iPad with a message that reads, "Otto out, Guate(mala) can't bear you" during a protest against Guatemala's President Otto Perez in Guatemala City, Guatemala, August 21, 2015. Guatemala's attorney general sought to impeach Perez on Friday over a customs fraud that led to the arrest of his former vice president, deepening a government crisis ahead of presidential elections next month. Perez's conservative administration has spent much of this year mired in public protests and scandals over corruption allegations against senior officials, several of whom the retired general fired during a cabinet purge in May.
