WASHINGTON, D.C.: The US Navy plans to build sprawling detention centers for tens of thousands of immigrants on remote bases in support of President Donald Trump's 'zero tolerance' policy against unlawful migration, a report said Friday.

According to a draft memo obtained by Time magazine, the navy plans to build 'temporary and austere' tent cities to house 25,000 migrants across three abandoned air fields in Alabama, 47,000 people at a facility near San Francisco, and another 47,000 at a training center in southern California.
