Deaths of immigrants held in US detention centres have surged during Donald Trump’s second term.

The United Nations High Commissioner for Human Rights, Volker Turk, has called for an independent investigation into the severe uptick in deaths in migrant detention centres during President Donald Trump’s second term in office.

In a statement on Friday, Turk expressed concern over the lack of transparency over those deaths, at least 19 of which have occurred so far this year, according to US government statistics.

“Those responsible for violations of the law must be held to account, and the rights of the victims’ families to truth, justice and reparation and guarantees of non-recurrence must be upheld,” the UN rights chief said.

Deaths in immigrant detention centres have surged during Trump’s second term in office, a by-product of what rights groups and immigration lawyers have depicted as systematic neglect, inhumane conditions and abuses.

The Trump administration has sought to rapidly expand the network of immigrant detention centres, some operated by private contractors, as it seeks to carry out the mass deportation of immigrants in the US.

Trump stated in a social media post on Friday that his administration has the “Highest Average Daily Arrest Rate by ICE and CBP, including Total Detention, with Final Orders of Removal, than any other president, by far!”

The reported death of a Georgian man, Mamuka Artmeladze, in a detention facility in Louisiana on June 4 increased the number of fatalities so far this year to 19, compared to 33 last year and 11 in 2024.

“The mortality rate of deaths in ICE custody is at its highest level in over a decade and has more than doubled since Trump’s second term began,” the watchdog group Human Rights Watch wrote in a report on detention deaths earlier this month. “The rate is nearly four times that of the Biden administration and more than two and a half times as high as that of the first Trump administration.”

That report said the 52 people who have died in detention during Trump’s second term ranged in age from 19 to 75 and came from 20 different nationalities.

Turk wrote on Friday that there have been “concerning allegations regarding the use of force” at such facilities and that five of the deaths recorded in 2026 were classified as suicides.

He also expressed concern over the reported use of solitary confinement, which is associated with a heightened risk of suicide and considered a form of torture by the UN after a period of 15 days.

“All these factors exacerbate vulnerability and raise serious concerns as to whether some of these deaths in ICE custody could have been prevented,” he said.
