Dozens have been injured and an unknown number killed in a massive explosion at a fertilizer plant in the town of West near Waco, Texas.
It's possible the number of casualties could rise as high as 60 to 70 dead, according to Dr. George Smith, the emergency management system director of West. "That's a really rough number, I'm getting that figure from firefighters, we don't know yet," he told CNN. "We have two EMS personnel that are dead for sure, and there may be three firefighters that are dead."
Sixty-six injured people were taken to Hillcrest Baptist Medical Center in Waco, 20 miles from the explosion. Thirty-eight of them were seriously hurt, according to the hospital's CEO.
"It was a like a nuclear bomb went off," said the town's mayor, Tommy Muska. The blast was audible 45 miles away. To get a sense of its scale, watch the live video made by a father and his little daughter (warning: not for the faint of heart):
It's not known what caused the explosion.
