French chemicals group Arkema confirmed on Thursday two explosions at its plant in Crosby, Texas, and added there was a risk of further explosions at the site.

"We want local residents to be aware that the product is stored in multiple locations on the site, and a threat of additional explosion remains," Arkema said in a statement.

"Please do not return to the area within the evacuation zone until local emergency response authorities announce it is safe to do so," it added.
