MEXICO CITY — One U.S. law enforcement agent was killed and another wounded in a roadside attack in northern Mexico on Tuesday, marking a lethal escalation in the ongoing drug fight here, officials said.
Two agents from U.S. Immigration and Customs Enforcement were traveling in a dark-colored SUV on the highway between Monterrey and the Mexican capital when they were fired upon.
Homeland Security Secretary Janet Napolitano said the agents were "shot in the line of duty." One agent, Jaime Zapata from the ICE office in Laredo, Texas, died of his injuries. The second agent, who was not identified, was shot in the arm and leg and remains in stable condition.
"Let me be clear: Any act of violence against our ICE personnel … is an attack against all those who serve our nation and put their lives at risk for our safety," Napolitano said.
The Mexican Foreign Ministry vowed to seek the assailants.
Attacks against U.S. law enforcement in Mexico are rare. An undercover U.S. drug agent was killed in the line of duty in Mexico in 1985, when the Drug Enforcement Administration's Enrique "Kiki" Camarena was kidnapped and tortured by narcotics traffickers in Guadalajara.
Camarena's killing, with the apparent complicity of corrupt Mexican officials, created a major strain in U.S.-Mexico relations and prompted a DEA investigation. At one point, U.S. investigators seized Mexican suspects and whisked them back to the United States for trial despite protests from the Mexican government.
Until now, the aggressive U.S. response to Camarena's murder has often been cited to explain why Mexican drug cartels have not targeted U.S. authorities operating in the country, knowing they would provoke the wrath of the U.S. government.
According to Mexican news accounts, police say the attack against the ICE agents took place in the state of San Luis Potosi, on Highway 57 near the town of Santa Maria del Rio.
The reason for the attack and the assailants' identities were not clear. More than 34,000 people have died in drug violence in the past four years as Mexico wages a U.S.-backed fight against criminal organizations.
