U.S. Border Patrol agents fired gunshots into Mexico over the weekend after being attacked during a marijuana seizure in Mission, Texas, the agency told CNN on Monday.
The incident between border patrol agents and alleged drug traffickers took place around 7:40 a.m. Saturday, Border Patrol spokeswoman Rosalinda Huey said.
"Our agents were being fired upon and they did respond with fire back into Mexico," she said. "I don't have the number of how many people were involved. But none of our agents were injured."
Agents seized over 1,000 pounds of marijuana during the incident, according to Huey. The incident is under investigation by the Drug Enforcement Administration, the FBI and the Mexican government, Huey said.
