Rising Toll, Shrinking Oversight

The United Nations High Commissioner for Human Rights has called on the United States to investigate all deaths in immigration detention and to establish stronger independent oversight of a system that, by the UN’s account, is expanding faster than it can be held accountable.

A Mounting Death Toll

Volker Türk, the UN rights chief, issued a formal statement on June 26th citing ICE data showing that 18 people died in immigration custody in the first five months of 2026, more than double the eight deaths recorded in the same period last year. An additional death on June 4th brought the year’s total to 19. In 2025, 33 people died in ICE custody, compared with 11 in 2024. The trajectory is steep and accelerating.

Five of the officially recorded deaths in 2026 were classified as suicides. Türk noted concerning allegations regarding the use of force in immigration detention facilities, though ICE has not acknowledged systemic problems. The lack of transparency surrounding the circumstances of deaths and the whereabouts of detainees during transfers compounds the difficulty of independent assessment.

Conditions And Capacity

ICE currently holds more than 60,000 people in immigration detention, with plans announced to expand that capacity to 90,000 by the end of the year. Türk described conditions in facilities as frequently inhuman, including inadequate healthcare and food, exposure to diseases and prolonged use of solitary confinement. He stated that prolonged or indefinite solitary confinement could amount to cruel, inhuman or degrading treatment under international human rights law.

Uncertainty about legal status, he added, contributes to significant psychological distress among detainees. The cumulative effect of these conditions raises serious questions, in his assessment, about whether some of the deaths in ICE custody could have been prevented.

Alternatives And Accountability

Türk urged the US government to prioritise alternatives to immigration detention, particularly for pregnant women and those with significant medical or mental health conditions. Children, he maintained, should never be subject to immigration detention, regardless of the immigration status of either the child or the child’s parents.

He called on ICE to ensure that detention facilities comply with international human rights standards: humane conditions, timely healthcare, family notification, an end to overcrowding and access to legal representation, consular assistance and interpretation services. He also stressed the role of the US Congress in overseeing detention conditions and associated public funding.

Beyond conditions and accountability, Türk denounced the continued dehumanisation and criminalisation of migrants and refugees in public discourse and policy. He expressed support for lawyers, journalists, faith organisations and civil society groups advocating on behalf of detainees. His concluding principle was unambiguous: no one should be returned to a place where they could face serious human rights violations or irreversible harm.
