Civil organisations and supporters of the party of the Democratic Revolution (PRD) wave flags during a march to protest against the privatization of the state-oil monopoly Pemex at Zocalo square in Mexico City, January 31, 2014. Pemex has struggled to exploit Mexico's oil reserves due to a lack of investment, high taxes and persistent allegations of corruption. Mexico's crude output peaked at 3.4 million barrels per day in 2004 and has since fallen by more than a quarter. The government says the overhaul is vital to boosting growth that has long lagged behind regional peers. REUTERS/Edgard Garrido (MEXICO - Tags: ENERGY BUSINESS POLITICS CIVIL UNREST) less
