The FBI is examining whether a package explosion at a FedEx facility outside of San Antonio is connected to the series of bombs that have rocked Austin, Texas, CNN reports.

A FedEx employee in Schertz, Texas, was injured in the explosion at the facility but did not have life-threatening injuries, according to the Schertz Police Department.

Local law enforcement said they are working with federal investigators about the latest explosion.

According to The New York Times, officials have said that the package was going to an address in Austin and that it may be connected to earlier reported incidents.

Officials told the Times that the most recent package contained shrapnel, which was found in the Austin bombs.

The past 17 days have left residents of the Texas capital on edge; two people were killed and four others injured in package explosions that began on March 2.

Investigators are still determining if the series of bombing as are racially motivated because many of the victims are people of color.

Three members of the Congressional Black Caucus have called for the explosions to be labeled as terror attacks and want to know if they are racially motivated.

“These bombing must be classified as ongoing terrorist attacks and should be investigated as such,” read the statement from Homeland Security Committee Ranking Members Bennie Thompson, Cedric Richmond and Sheila Jackson Lee. “Also, we need to understand if these attacks are ideologically or racially motivated. We cannot stand idly by while our communities are under attack.”
