An explosion at a chemical plant in Texas early Wednesday sent a large fireball into the sky, media reports said, triggering a mandatory evacuation.
"Please be aware that there is a mandatory evacuation for everyone within a 1/2 mile of the TPC plant in Port Neches," local fire officials said in a post on the Nederland Volunteer Fire Department's Facebook page.
