Human rights groups have accused U.S. authorities of using Guantánamo Bay for decades to detain migrants fleeing Haiti, Cuba and other Caribbean nations.

The Guantanamo Bay detention camp, often shrouded in secrecy, is a sprawling facility divided into multiple compounds, each with varying levels of security and accommodation.

The US has maintained a migrant detention facility there for decades that is separate from the notorious high-security jail for foreign terror suspects, including alleged 9/11 mastermind Khalid Sheikh Mohammed.
