The mass shooting at a U.S. Immigration and Customs Enforcement (ICE) field office in Dallas is now being described by federal officials as terrorism after initially being labeled by authorities as “targeted violence.”

Acting U.S. Attorney for the Northern District of Texas, Nancy Larson, announced on Thursday that the suspected gunman, a deceased 29-year-old named Joshua Jahn, had hoped his attack would unleash “terror” on ICE personnel, not just during the shooting but into the future.
