Explosion at Mexico oil company kills 14

MEXICO CITY -- An explosion at the headquarters of Mexico's state-owned oil company in the capital killed 14 people and injured 80 Thursday as it heavily damaged three floors of the building, sending hundreds into the streets and a large plume of smoke over the skyline.

There were reports that people remained trapped in the debris -- as many as 30 according to civil protection and local media -- 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.
