Tensions remain high on Friday as two separate shootings in Minneapolis and Portland, Oregon, sparked public outrage over the Trump administration's immigration enforcement operations across the country.

The Portland shooting unfolded on Thursday afternoon as U.S. Border Patrol agents were conducting a targeted vehicle stop, the Department of Homeland Security said in a statement. The driver, a suspected Venezuelan gang member, "weaponized his vehicle" and attempted to run over agents, according to the DHS.

DHS said "an agent fired a defensive shot" as the driver and a passenger drove away. Portland police confirmed that a shooting involving federal agents left a man and a woman injured. Their conditions were not immediately known, and officials did not disclose the names of the injured people.

"We understand the heightened emotion and tension many are feeling in the wake of the shooting in Minneapolis, but I am asking the community to remain calm as we work to learn more," Portland police Chief Bob Day said in a statement.

The shooting came just a day after a federal agent from U.S. Immigration and Customs Enforcement shot and killed Renee Nicole Good, a 37-year-old mother of three, in her car in Minneapolis. The two shootings have prompted protests in multiple U.S. cities, with thousands of people gathering for marches and vigils.
