The death toll from the explosion at Pemex reached 36 after another body was recovered from the rubble on Sunday, according to local media. The disaster on Thursday struck two months into Mexico's President Enrique Pena Nieto's presidency, just as Congress was preparing to discuss his plans to open up the state-run energy industry to more private investment.
