Trump has vowed to carry out “the largest deportation operation in American history”, affecting an estimated 11 million undocumented migrants in the US.
On his first day in office, he signed orders declaring a “national emergency” at the southern border and announced the deployment of more troops to the area while vowing to deport “criminal aliens”.

The White House has also halted an asylum programme for people fleeing authoritarian regimes in Central and South America, leaving thousands of people stranded on the Mexican side of the border.
