Mexico City- Unknown gunmen killed a U.S. Immigration and Customs Enforcement agent and wounded another Tuesday as they drove from Mexico City to Monterrey.
The Department of Homeland Security said the two special agents were assigned to the ICE office in Mexico City. Officials did not say why the two men were driving to Monterrey.
One agent, whose name has not been released, was critically wounded in the attack and died from his injuries. The second agent was shot in the arm and leg and is in critical condition.
Video shot at the scene showed a blue sports utility vehicle with several large bullet holes guarded by heavily armed Mexican federal police at the side of the highway.
U.S. Law enforcement agencies are working closely with Mexican authorities who are investigating the shooting.
“Any act of violence against our ICE personnel, or any DHS personnel, is an attack against all those who serve our nation and put their lives at risk for our safety," said Department of Homeland Security Secretary Janet Napolitano. “I ask that you join me in praying for our fallen and wounded colleagues. Please keep them, and all our DHS personnel serving abroad or in harm's way, in your thoughts."
More than 15,000 deaths were blamed on drug violence in Mexico last year, but despite growing domestic criticism of the government's war n drug cartels, the government has vowed to press on.
Attacks on Mexican police are common, but attacks on U.S. government employees have been rare.
