MEXICO CITY – Mexico's state-owned oil company says rescuers have found another body amid the rubble of a headquarters building damaged by a still-unexplained blast. The find raises the death toll of Thursday's explosion to 34 people.
Petroleos Mexicanos operations director Carlos Murrieta says rescue crews are still looking for three people in the rubble, and believe they're in the most damaged part of the building.
Officials still have not given any cause for the explosion, though they have said they suspect it was an accident. The blast also injured 121 people.
Rescuers had concluded their search Friday but resumed operations when they suspected more bodies were in the rubble. The latest body was found Saturday, and the news was announced via Twitter by Mexican President Enrique Pena Nieto.
