Torre Ejecutiva Pemex explosion

On 31 January 2013 in Mexico City, an explosion caused by a gas leak occurred beneath Building B-2 at the Torre Ejecutiva Pemex (Pemex Executive Tower), a skyscraper complex that is the headquarters of Pemex, the Mexican state oil company. At least 37 people died and another 126 were injured when an explosion occurred in a building adjacent to the main tower. Earlier in the day, Pemex sent out a tweet saying that the building was being evacuated due to a "problem with the electrical system" in the complex that includes the skyscraper.
