MEXICO - Unknown gunmen killed a U.S. customs agent and wounded another as they drove from Mexico City to Monterrey.
Special agent Jaime Zapataa was killed when suspected drug gang members ambushed them on the road between Mexico City and Monterrey.
The wounded agent is identified as Victor Avila.
ICE public affairs did not say why the two Immigration and Customs Enforcement agents were driving to Monterrey.
Video shot at the scene showed a blue SUV with several large bullet holes guarded by heavily armed Mexican federal police at the side of the highway.
More than 15,000 deaths are blamed on drug violence in Mexico last year.
Attacks on Mexican police are common but attacks on U.S. government employees have been rare.
