That was the initial report. First it was a small fire but when water was applied, it cause the explosion. My mom said that she was hearing nothing in the plant should have exploded this morning, but this is not the first time it has happened. One of the worst industrial accidents was in a Texas fertilizer plant, years ago. It (an explosion) killed many people.
Yes, several fire fighters, first responders, and possibly some police officers are missing. Early this morning they had 700 emergency responders on scene. It sounds like people from all over went to help them.
