In Mexico City, some migrants have built tent cities and slept on the streets. In a country long sympathetic to migrants, neighbors are protesting.

Groups of migrants began to be deported to Mexico on Tuesday night as border shelters and authorities brace themselves for President Donald Trump's promised campaign of mass deportations.

Central American nations could reach similar agreements with US to accept deportees from other countries just like Mexico receiving non-Mexican migrants from US, President Claudia Sheinbaum said.
