A demonstrator holds up a poster at the perimeter of the Congress building during a demonstration against the energy reform bill in Mexico City December 11, 2013. Mexico's Senate on Wednesday signed off on the energy bill that aims to lure private capital into the state-run oil and gas industry in the biggest shake-up since a 1938 nationalization, sending it to the lower house for debate and final approval. The overhaul is designed to entice private companies and oil majors to operate independently in Mexico or partner with state oil giant Pemex through production- and profit-sharing, service contracts and licenses. The poster reads "Pemex is not privatized". REUTERS/Edgard Garrido (MEXICO - Tags: CIVIL UNREST POLITICS ENERGY BUSINESS) less
