Guatemala's Otto Perez resigned as president and was jailed on Thursday while a judge weighs charging him in a corruption scandal that gutted his government and plunged the country into a political crisis days before a presidential election. In an emergency session, Congress approved Perez's resignation after the retired general quit overnight. Former vice president Alejandro Maldonado was sworn in as president to fill out the remaining months of Perez's term. REUTERS/Jose Cabezas
