President Trump has ordered the construction of a 30,000-bed facility to hold migrants at the notorious US naval facility at Guantánamo Bay, Cuba, as part of his mass deportation campaign. The US base has been used to house terrorism suspects since 2002, becoming synonymous with torture and unlawful imprisonment. The US has secretively detained refugees and migrants intercepted at sea at Guantánamo Bay for decades, but the facility has not previously been used for people apprehended on US soil or at this scale.

The US Department of Defense (DoD) announced on Jan. 6 the transfer of 11 Yemeni detainees from Guantanamo Bay prison to Oman, marking a significant step in reducing the population of the detention facility. The DoD stated that the Periodic Review Board (PRB) "determined by consensus" that the detention of the Yemeni prisoners under the law of war was no longer necessary, as they did not continue to pose a significant national security threat. The DoD added that any potential risk from the prisoners could be adequately mitigated.

The Pentagon announced Dec. 30 that the US has repatriated Guantánamo prisoner Ridah bin Saleh al-Yazidi to Tunisia after more than two decades in detention. Al-Yazidi, identified as ISN-038, was transferred to Tunisia 11 months after Secretary of Defense Lloyd Austin informed Congress on Jan. 31, 2024 about the agreement reached for his return. His transfer followed a thorough interagency review process mandated by Executive Order 13492, issued in 2009. Of the 12 Tunisians who were detained at Guantánamo over the years, al-Yazidi, 59, was the only one still held there, with the others having been transferred to Tunisia or to third countries.

The US Department of Defense (DoD) announced Dec. 11 the transfer of Mohammed Farik bin Amin and Mohammed Nazir bin Lep from the Guantanamo Bay detention facility. According to DoD detainee profiles, bin Amin and bin Lep arrived at Guantanamo in September 2006. The US accused the individuals of planning attacks in California and facilitating terrorist operations in Southeast Asia. Both men pled guilty to several offenses.

US Defense Secretary Lloyd Austin on Aug. 2 rejected a controversial plea deal that would have prevented three accused 9-11 terror attack planners from facing the death penalty. Two days earlier, a letter to the families of 9-11 victims revealed that accused co-conspirators Khalid Shaikh Mohammed, Walid Bin 'Attash and Mustafa al Hawsawi had pled guilty to orchestrating the attacks that claimed nearly 3,000 lives on Sept. 11, 2001.

The UN Working Group on Arbitrary Detention released a report May 30 finding that Afghanistan, Lithuania, Morocco, Poland, Romania, Thailand, United Arab Emirates (UAE) and the US all participated in human rights violations against Abd al-Rahim Hussein al-Nashiri, the man accused of involvement in the bombing of the USS Cole in 2000. Al-Nashiri is currently held in Guantanamo Bay prison, though he is said to have been previously detained in the territories of each of these countries. 

The US Department of Defense on June 24 announced the release of Asadullah Haroon Gul, an Afghan national, who had been held for 15 years without charge at the Guantánamo Bay detention camp. Gul was incarcerated at Guantánamo in 2007 on accusations of being a member of al-Qaeda and Hezb-e-Islami (HIA), an insurgent group that fought against the US in Afghanistan. HIA signed a peace agreement with the US-backed Afghan government in 2016.

A group of United Nations experts have condemned the US Guantánamo Bay detention facility in Cuba, calling it a site of "unparalleled notoriety." The statement came on the eve of Jan. 11, which marks the twentieth anniversary of the arrival of the first terrorism suspects at Guantánamo.
