Despite The FBI having not publicly released the names or nationalities of the 20 people killed Saturday at a shopping complex in El Paso, Mexican officials have claimed that nine Mexicans were wounded in the shooting, prompting Mexico’s ambassador to Washington, Martha Bárcena, to tweet:

"The intentionality of the attack against the Mexicans and the Latino community in El Paso is frightening. NO to hate speech. NO to xenophobic discourse. "

This was followed by Mexico President Andrés Manuel López Obrador commenting that the number of Mexicans killed in the shooting in the border city of El Paso, Texas, has risen to seven, proclaiming that says that:

...the events in Texas reaffirm his conviction that "social problems shouldn't be confronted with the use of force and by inciting hate."

Which was swiftly followed by a video statement from Mexican Secretary of Foreign Affairs Marcelo Ebrard on Sunday that his country will take legal action against the United States over Saturday's mass shooting at a Walmart in El Paso, Texas.

Ebrard said in the video that AMLO has instructed officials to make sure "the position from Mexico translates first as protecting the affected families and after in effective, swift, expeditious and forceful legal actions to protect Mexicans in the US... in accordance with international law.”

Ebrard concluded:

“Mexico manifests their profound rejection and complete condemnation of the barbaric act where innocent Mexican men and women lost their lives.""

Critically, as The Washington Post reports, the remarks represented a toughening of Mexico's official reaction to the shootings. On Saturday, AMLO appeared to play down any U.S. government responsibility for the violence, saying the attack was "a product of [societal] discomposition, of problems certain people have. It's not a generalized issue."
