U.S. Secretary of State Marco Rubio says the United States is designating two Ecuadorian gangs as foreign terrorist organizations. It's the Trump administration’s latest step to target criminal cartels in Latin America. The announcement came Thursday during Rubio’s stop in Ecuador as part of a trip to Latin America that's been overshadowed by a U.S. military strike against Venezuela’s Tren de Aragua gang. That attack has raised concerns in the region about what may follow as President Donald Trump's government pledges to step up military activity to combat drug trafficking and illegal migration.
