Volker Turk, the high commissioner for human rights at the United Nations, has issued some of his harshest criticism yet of the recent sanctions the United States has imposed on Cuba.
On Monday, Turk drew a line between the increasing restrictions on the Cuban economy and reports of heightened death rates, particularly among children.

“The fuel restrictions imposed since early 2026 and recent tightening of extraterritorial sanctions, taken together, are directly harming Cubans, especially the most vulnerable,” Turk said in a statement.
“Children are dying because doctors lack access to essential medical supplies and medicines. This is unacceptable.”
Such “severe sanctions”, he added, run contrary to the “basic principles of international human rights law”. He called for them to be “lifted immediately”.
Turk’s comments are a direct response to the suite of actions taken under US President Donald Trump to tighten pressure on Cuba, a Caribbean island that has already weathered a decades-long US trade embargo.
Starting in January, the Trump administration moved to cut off Cuba’s foreign oil supply, a linchpin for its ageing energy grid.
First, it severed supplies of oil and funds from Venezuela. Then, on January 29, Trump issued an executive order declaring Cuba to be an “unusual and extraordinary threat” to US national security. As such, he said, any country that supplied it with oil would be subject to steep tariffs.
In the months since, the Trump administration has continued to layer sanctions on Cuba. In May, for instance, penalties were announced against Cuba’s Interior Ministry, its National Police and its Directorate of Intelligence.
Those were followed this month by sanctions targeting Cuba’s president, Miguel Diaz-Canel, as well as members of his family.
The sanctions are designed to penalise those “responsible for repression” in Cuba, an island whose communist government has been accused of stifling dissent, as well as imprisoning and torturing activists.
Turk on Monday acknowledged Cuba’s human rights record and called on the country to “release all those arbitrarily detained”.
But he also pointed to the mounting death toll associated with the US sanctions, which have isolated the island country from much of the world.
The sanctions freeze any US-based assets the target may have, but they also prohibit entities from conducting business with the sanctioned parties. That can result in difficulties accessing global financial systems and other international platforms.
The de facto oil blockade has also resulted in the increasing frequency of power outages, and essential services like public transportation and medical care have faced reductions. Turk pointed to those downstream effects in his remarks.
“Cuba faces increasing isolation,” he said. “Companies are leaving. Fewer airlines fly to the country. It is almost disconnected from international payment systems.”
Turk’s office has also highlighted the human costs of the sanctions. According to the statistics it cited, infant death rates have doubled, reaching 9.9 for every 1,000 births. The survival rate for childhood cancer, meanwhile, has declined from 85 to 65 percent.
In March, the Cuban government also warned of medical needs going unanswered as a result of the energy shortage. It estimated that there was a backlog of 96,387 people awaiting surgery, 11,193 of whom were minors.
It also underscored that 16,000 patients needed radiotherapy, and another 2,888 required dialysis, two treatments that depend on steady electrical supplies.
Turk’s remarks also pointed to the risks posed by the Atlantic hurricane season and other natural disasters. Within hours of his remarks, western Cuba was rattled by an earthquake. Summer heat alone could cost lives, he explained.
“Rising summer temperatures risk increasing the spread of vector borne and waterborne diseases,” Turk said.
“The hurricane season further increases exposure. This creates a perfect storm for social and economic deterioration and suffering for the Cuban people.”
Trump has repeatedly suggested that he is considering military action in Cuba to remove its leadership after the US-Israel war on Iran reaches an end.
Since January, only one Russian oil tanker has been allowed to reach the island, leaving its foreign fuel supplies largely depleted.
