Slow down.
We don't know anything yet, except that a whole town has been devastated by this blast. They're still airlifting victims out to nearby hospitals.
There'll be lots more information forthcoming after investigators do a forensic analysis of the scene.
The mayor just said they went to fight the fire then it exploded.
He also said they got all the residents of the nursing home out. Thank God!
He also said what they need is prayers.
