"The truth is that the forces are doing everything humanly possible and will continue until they can contain and control the fires."

Bachelet said she planned to meet with the intelligence heads of police and armed forces to discuss the investigation into the cause.
"Because there are multiple points of origin, we cannot dismiss the possibility that there might be an intentional component here," she said Thursday in Santiago.
