Mexican officials condemned a fatal, cross-border shooting of a Mexican citizen by U.S. Border Patrol agents that took place on Saturday, July 7.

At least two U.S. Border Patrol agents fired their weapons in reaction to rock throwing and after observing someone aiming a weapon at them near the Tomates-Veterans international bridge between Matamoros, Mexico and Brownsville, Texas.

“When the agent was unable to take cover, he fired his service weapon in defense,” said Enrique Mendiola, Jr., U.S. Border Patrol spokesperson, in a written statement.

The Secretaria de Relaciones Exteriores (SRE), Mexico’s foreign affairs authority, called for an exhaustive investigation “that should be taken to its ultimate consequences.”

“[We] reiterate that the disproportionate use of lethal force in immigration control is unacceptable under any circumstances,” an SRE statement said.

The shooting Saturday is the latest in a string of incidents involving U.S. Border Patrol fatal shootings across the U.S. border.
