At least seven people sustained light injuries when fire broke out at an oil refinery in the southeastern Mexican state of Veracruz, Mexican state-owned petroleum company Pemex said

Mexico's new President Andres Manuel Lopez Obrador on Wednesday announced that he was suspending oil auctions for three years in order to boost national production, clarifying, however, that contracts awarded under the 2013 energy reform would not be canceled.

Mexico's President-elect Andres Manuel Lopez Obrador, who is taking office as president Saturday, said Friday he was calling on oil companies to conduct reforms in the same way as in 1938, when the country's oil industry was nationalized.

Enrique Pena Nieto is spending his last day as Mexican president away from his homeland and in Buenos Aires for the G20 summit. His participation in the summit, however, will be limited, because Pena Nieto has to be in Mexico City on December 1 to pass the baton of governance to his successor, Andres Manuel Lopez Obrador.

Mexican President-elect Andres Manuel Lopez Obrador has pledged to save the country's oil sector just like former Mexican President Lazaro Cardenas, who headed the country from 1934 to 1940, had done.
