Civil liberties and immigration advocacy groups are suing the Trump administration over its use of the base for immigration detention.

Sitting on the front row of a war court on the US's Guantanamo Bay naval base in Cuba, Khalid Sheikh Mohammed, one of the world's most notorious defendants, appeared to listen intently.

Austin withdrew the pre-trial agreements in August made with the defendants, who are all being held in Guantanamo Bay ... throw out plea deals for Khalid Sheikh Mohammed and two other defendants ...

A US court has temporarily blocked Khalid Sheikh Mohammed ... The torture of detainees at Guantanamo means that some of Mohammed and his co-defendant’s statements might potentially be unusable ...

It is unclear why the migrants have been removed from the US military base. The president orders the construction of a detention facility at the US Navy base, prompting an angry backlash from Cuba.
