US border guard killed by car speeding to Mexico

LOS ANGELES (AFP) — A US border guard was struck and killed Saturday while trying to flag down two cars that were speeding toward the Mexican border near Yuma, Arizona, said Homeland Security Secretary Michael Chertoff.

"The agent was struck and killed while attempting to stop two vehicles believed to have illegally entered the country and were absconding back into Mexico," he told reporters.

"I have spoken to the Mexican ambassador (Arturo Sarukhan) who gives me both his condolences and deep assurance that their government will be resolute in tracking down the perpetrators, and bringing them to swift justice," Chertoff added.

He said he would use "the full force of the law" in pursuing the perpetrators of this "heinous act of violence."
