Mexico's government said Wednesday it has helped 10 Mexican citizens file lawsuits against Walmart over an August shooting at a store in El Paso, Texas, where a suspected white nationalist killed 22 people.

"The objective of these suits, presented in El Paso county, is to hold the company responsible for not taking reasonable and necessary measures to protect its clients from the attack," the foreign ministry said in a statement.

"The plaintiffs are seeking not only justice for themselves, but security for the general public."

Eight Mexicans were killed in the August 3 attack in El Paso, a city on the US-Mexican border where 83 percent of the population is Latino. The alleged shooter, Patrick Wood Crusius, 21, reportedly told police he was trying to kill as many Mexicans as possible. He posted a manifesto online before the attack denouncing a "Hispanic invasion" of Texas.
