A trooper at the scene warned bystanders of a "major fuel leak" and told them to stay back, according to the outlet.

"I ask locals to follow law enforcement instructions, and to look to official channels and trusted sources for more information as it becomes available."

Searsmont sits in a rural area about one and a half hours northeast of Portland and four hours north of Boston.
