Donald Trump’s Alligator Alcatraz migrant detainment camp must be closed down, a judge has ruled.

A ruling from US District Judge Kathleen Williams citing environmental concerns bans new migrants from being moved to the detention camp.

The order gives the state 60 days to transfer current detainees to other facilities before dismantling the site.

In her 82-page order, published in the US district court’s southern district of Florida on Friday, the Miami judge found the facility was causing severe and irreparable damage to the fragile Florida Everglades.

The judge’s ruling is a blow to Mr Trump and his efforts to carry out the largest deportation in US history.
