Mexican troops arrived in Ciudad Juárez and Tijuana this week and will soon patrol 18 cities near the Mexico-U.S. border.

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.
