Hundreds of Mexican soldiers were mobilized on Tuesday to the border with the United States as part of an agreement that halted U.S. tariffs on Mexican imports under the condition the Latin American country cracks down on fentanyl trafficking.

The deployment includes an unspecified number of Mexican army soldiers and National Guard troops going to Juárez and the Chihuahua-state border towns of Ojinaga, across from Presidio, Texas, and Palomas, across from Columbus, New Mexico, reported La Verdad Juárez news site.
