There are still no firm answers this hour about the cause of a blast at the Mexico City headquarters of the state-owned oil company that killed 14 people and injured 80 today. More from the Associated Press:
There were also reports that as many as 30 people were trapped in the debris from the explosion, which occurred in the basement of an administrative building next to the iconic, 52-story tower of Petroleos Mexicanos, or Pemex.
There was no immediate cause given for the blast, which also damaged the first and second floors of the auxiliary building in a busy commercial and residential area. But in an earlier Tweet, Pemex said it had evacuated the building as a precautionary measure because of a problem with the electrical system.
"It was an explosion, a shock, the lights went out and suddenly there was a lot of debris," employee Cristian Obele told Milenio television, adding that he had been injured in the leg. "Co-workers helped us get out of the building."
The tower, where several thousand people work, was evacuated. The main floor and the mezzanine of the auxiliary building, where the explosion occurred, were heavily damaged, along with windows as far as three floors up.
