MEXICO CITY (AP) — In a rare show of force Friday, Mexico sent hundreds of immigration agents, police and National Guard officers marching through the streets of the capital of the southern state of Chiapas to launch an operation to crack down on migrant smuggling. The parade Friday in the city of Tuxtla Gutierrez came one day after Mexico announced it was banning entry for nonessential travel on its southern border with Guatemala to prevent the spread of COVID-19. The restrictions went into effect Friday. Mexico will deploy checkpoints and drones and station officers along the Suchiate River, which marks part of the border, to deter irregular entry. The crackdown is especially aimed at people traveling with minors.
