A U.S. Border Patrol agent was fatally shot Monday in Vermont on a highway just south of the Canadian border, according to authorities.

The identity of the agent who was killed has not been released and the FBI said there isn't a threat to the public, according to The Associated Press.

Acting secretary of the Department of Homeland Security Benjamine Huffman and the FBI confirmed the death.

Another agent was also shot during the incident and was injured. A suspect has been taken into custody and an investigation is ongoing. A portion of Interstate 91 was closed following the shooting.

There is not information on the suspect at this point. Huffman said the death of the agent will be investigated "swiftly."

“Every single day, our Border Patrol agents put themselves in harm’s way so that Americans and our homeland are safe and secure,” he said in a statement.
