President Donald Trump celebrated the speedy construction of “Alligator Alcatraz,” a new immigrant detention facility in the heart of the Florida Everglades, and warned that the only way for detainees to get out of this “treacherous” region is through deportation.

A new migrant detention centre in Florida, planned to open in weeks, will cost about $450m (£332m) a year to run.

President Donald Trump visited a new immigration detention center in the Florida Everglades on Tuesday as state officials showcased what critics are condemning as an inhumane makeshift prison camp and what supporters are embracing as a national model for aggressively ramping up detention and deportation efforts.
