BROWNSVILLE, TEXAS - A Texas rancher who works both sides of the border was killed in a blast after driving over an explosive device in the Mexican state of Tamaulipas near Brownsville.

Texas officials believe the improvised explosive was left there by a drug cartel.

74-year-old Antonio Cespedea Saldierna from Brownsville, Texas, was killed alongside Horacio Lopeza Pena. Pena's wife, Nifna Griselda Ortega was also injured in the blast. Her condition is unknown, and it was not made clear where Pena and Ortega are from.

Texas ranchers who frequently cross the border for work have been urged by Sid Miller, the Texas Agriculture Commissioner, to use caution on the job.

Last month, the Tamaulipas issued a warning to its residents not to touch or transport unknown objects found on the ground because of ongoing violence between cartels. Tamaulipas is also listed on the "Do Not Travel List" by the U.S. Department of State due to its high rate of crime and kidnapping.

This Facebook post shows some examples of what could potentially be an explosive device. Take a moment to commit them to memory if you live in a border town or travel through one frequently.
