Mayor Cruz Perez Cuellar of Ciudad Juarez expressed readiness to handle a potential influx of migrants as U.S. policies under President Donald Trump

A secret tunnel discovered last week on the U.S.-Mexico border will be sealed by Mexican authorities, an army official in Ciudad Juarez said Saturday.

Several migrants said they had recently arrived in Ciudad Juarez, Mexico after weeks of travel, only to find their CBP One appointments were cancelled.

Mexican authorities have begun constructing giant tent shelters in the city of Ciudad Juarez to prepare for a possible influx of Mexicans deported under U.S. President Donald Trump‘s promised mass deportations.

It may have been embraced by the Academy, but just a day after its debut in Mexico, the acclaimed “narco-musical” Emilia Pérez was already drawing sharp rebukes for superficial portrayals of sensitive subjects.

As the US plans to deport undocumented immigrants to Mexico, there are concerns that those who fled because of organised crime gangs will be thrust into danger on their return

In Tijuana, meanwhile, Mexican soldiers are helping to prepare for the consequences of it. The authorities have readied an events centre called Flamingos with 1,800 beds for the returnees, with troops bringing in supplies, setting up a kitchen and showers.

General Jose Lemus, commander of Ciudad Juarez's military garrison, said the tunnel "must have taken a long time" to build, suggesting "it could have been one or two years".

President Trump took action to close the nation’s southern border and terminate a widely used app. Many migrants expressed despair, and some moved to cross the border anyway.

The Mexican government plans to establish nine reception areas for deportees in Mexico's six northern border states over the coming weeks.

Ahead of the inauguration, migrant shelters south of the Rio Grande are far from full, a reflection of the tougher measures imposed on both sides of the border.

Mexico was raising sprawling tents on the U.S. border Wednesday as it braced for President Donald Trump to fulfill his pledge to reverse mass migration.
