Mexico's National Guard kills 2 Colombians and wounds 4 in an alleged confrontation near US border

Mexico's National Guard fatally shot two Colombians and wounded four others in what the Defense Department claimed was a confrontation near the U.S. border.

The shootings happened Saturday on a dirt road near Tecate, east of Otay Mesa on the California border, that is frequently used by Mexican migrant smugglers, the department said.

It wasn't clear whether the Colombians were migrants, but one Colombian who was not injured in the shootings was turned over to immigration officials, suggesting they were.

Mexico's Defense Department, which controls the National Guard, did not respond to requests for comment on that point.

If they were migrants, it would mark the second time in just over a month that military forces have opened fire on and killed migrants.

On Oct. 1, the day President Claudia Sheinbaum took office, soldiers opened fire on a truck, killing six migrants in the southern state of Chiapas. An 11-year-old girl from Egypt, her 18-year-old sister and a 17-year-old boy from El Salvador died in that shooting, along with people from Peru and Honduras.

Describing the events near Tecate on Saturday, the Defense Department said in a statement late Sunday that a militarized National Guard patrol came under fire after spotting two trucks in the area.

One truck sped off and escaped. The National Guard opened fire on the other truck, killing two Colombians and wounding four others. There was no immediate information on their conditions, and there were no reported casualties among the guardsmen involved.

One Colombian and one Mexican man were found and detained unharmed at the scene, and the departments said officers found a pistol and magazines commonly used for assault rifles at the scene.

Colombians have sometimes been recruited as gunmen for Mexican drug cartels, which are also heavily involved in migrant smuggling. But the fact the survivor was turned over to immigration officials and that the Foreign Relations Department contacted the Colombian consulate suggests they were migrants.

Cartel gunmen sometimes escort or kidnap migrants as they travel to the U.S. border.

The three National Guard officers who opened fire have been taken off duty.

Former president Andrés Manuel López Obrador , who left office Sept. 30, gave the military an unprecedentedly wide role in public life and law enforcement; he created the militarized Guard and used the combined military forces as the country's main law enforcement agencies, supplanting police. The Guard has since been placed under the control of the army.

But critics say the military is not trained to do civilian law enforcement work. Moreover, lopsided death tolls in such confrontations — in which all the deaths and injuries occur on one side — raise suspicions among activists whether there really was a confrontation.

For example, the soldiers who opened fire in Chiapas — who have been detained pending charges — claimed they heard "detonations" prior to opening fire. There was no indication any weapons were found at the scene.
