Officers were unable to move their vehicles, so they exited them, DHS said.

One of the drivers involved in the car-ramming was armed with a semi-automatic weapon, DHS said, and officers fired "defensive shots."

The allegedly armed woman, a U.S. citizen, was injured and allegedly took herself to a hospital for treatment, DHS said.
