An explosion in Mexico City yesterday is a developing story today. The blast tore through the offices of a state-owned oil company and sent thousands of panicked employees into the streets.
Authorities say 25 people were killed and more than 100 were injured. Crews are searching for people trapped in the Pemex complex, which includes one of the city's tallest buildings. And there's word a survivor has been pulled from the rubble. Nick Parker is live in Mexico City with details.
