Mexico on Wednesday raised sprawling tents on the US border as it braced for US President Donald Trump to fulfil his pledge to carry out mass deportations. In an empty lot right against the border with El Paso, Texas, cranes lifted metal frames for tent shelters in Ciudad Jurez. Enrique Serrano, an official in Chihuahua state, where Ciudad Jurez is located, said the tents erected for Mexican deportees were just the initial phase of a potential larger operation, and something authorities would scale up if the number of migrants gathering on the border continued to mount. He suggested migrants from other countries expelled from the US would be relocated to Mexico City or southern regions of Mexico as they've done previously. Nogales, Mexico -- across from Nogales, Arizona -- announced that it would build shelters on soccer fields and in a gymnasium. The border cities of Matamoros and Piedras Negras have also launched similar efforts. At a border crossing in Tijuana, Mexico, on Tuesd
