The United Nations’ top human rights official has issued an extraordinary warning about conditions in Cuba, arguing that recent U.S. sanctions and fuel restrictions are pushing the island into a deepening humanitarian emergency marked by medicine shortages, declining health outcomes, food insecurity, and prolonged power outages.
The statement from UN High Commissioner for Human Rights Volker Türk comes as Cuba faces one of its most severe crises in years. Hospitals are struggling to obtain critical supplies, food production has fallen sharply, humanitarian shipments have been disrupted, and residents are enduring blackouts that can last for most of the day. At the same time, concerns are growing over reports that the Trump administration may be laying the groundwork for a possible military confrontation with the island.
Rather than beginning with geopolitical tensions, Türk focused on the impact that sanctions are having on ordinary Cubans, particularly children and patients dependent on an increasingly strained healthcare system.
“The fuel restrictions imposed since early 2026 and recent tightening of extraterritorial sanctions, taken together, are directly harming Cubans, especially the most vulnerable,” Türk said. “Children are dying because doctors lack access to essential medical supplies and medicines. This is unacceptable. These sanctions must be lifted immediately.”
According to the Office of the United Nations High Commissioner for Human Rights, conditions on the island have deteriorated rapidly since Washington declared a national emergency in January, disrupting fuel shipments and accelerating a decline in Cuba’s already fragile energy reserves. By mid-May, daily blackouts were regularly exceeding 20 hours.
The consequences have spread through nearly every sector of Cuban society.
Healthcare has emerged as one of the most visible examples. The UN reports that essential medicines are available at only about 30 percent of normal supply levels. Services related to oncology and maternal health have been particularly affected, contributing to worsening outcomes for some of the country’s most vulnerable patients.
The human rights office reported that infant mortality has doubled to 9.9 deaths per 1,000 births. Childhood cancer survival rates have reportedly fallen from 85 percent to 65 percent as shortages of medications and medical supplies continue to affect treatment programs.
Cuban President Miguel Díaz-Canel acknowledged the growing challenges in an interview released Monday.
“We have very effective programs to care for children with cancer; today, these programs are limited by a shortage of medications and supplies, and as a result, the survival rates of these children with cancer are declining,” he said.
The healthcare crisis is unfolding alongside growing pressure on Cuba’s food system.
Because the island imports a significant portion of its food, disruptions to fuel supplies have affected agricultural production, transportation, and distribution networks. According to figures cited by the United Nations, food production has declined by approximately 60 percent while the cost of basic food items has increased sharply.
Humanitarian operations have also been affected. The UN reported that private companies, shipping firms, insurers, and financial institutions have become increasingly reluctant to engage with Cuba, in some cases imposing restrictions beyond those explicitly required under sanctions regulations.
The result has been a widening disruption of supply chains and procurement networks that humanitarian organizations rely upon to move food and other necessities.
According to the UN, the suspension of services by major shipping companies has already affected more than 2,900 metric tonnes of humanitarian food cargo.
The effects extend beyond shipping. Cuba is becoming increasingly disconnected from international payment systems, making it more difficult for organizations and businesses to purchase or transfer essential goods. Companies are reportedly withdrawing from the country, while airlines have reduced service.
Türk argued that these developments illustrate how broad economic restrictions can create widespread consequences beyond their stated political objectives.
“Such severe sanctions packages that target entire sectors of an economy and produce broad, indiscriminate and harsh effects on populations are incompatible with basic principles of international human rights law,” he said.
The UN human rights chief also warned that the crisis could worsen in the coming months due to environmental and seasonal pressures.
“Cuba faces increasing isolation. Companies are leaving. Fewer airlines fly to the country. It is almost disconnected from international payment systems. Rising summer temperatures risk increasing the spread of vector-borne and waterborne diseases.”
The island now faces the additional threat of hurricane season, which could place even greater strain on already weakened infrastructure, healthcare systems, and food supplies.
“The hurricane season further increases exposure. This creates a perfect storm for social and economic deterioration and suffering for the Cuban people,” Türk said.
While the humanitarian situation has drawn international concern, it is unfolding against a backdrop of escalating political tensions between Washington and Havana.
The Trump administration imposed the latest fuel restrictions in late January following events connected to Venezuela. Since then, the administration has continued to increase economic pressure on Cuba through additional sanctions targeting traders, insurers, shipping companies, and financial institutions.
Those measures have fueled concerns that economic pressure may be part of a broader strategy toward the island.
In late March, Trump publicly suggested Cuba could become the next target of U.S. action.
“Cuba is next, by the way,” Trump said.
Those concerns intensified after reporting by Politico in late May indicated that the Pentagon was putting “building blocks in place” for an invasion of Cuba and “positioning the troops and weapons needed for the US to launch a military attack.”
“All it needs is a final go-ahead from Donald Trump,” the outlet reported.
The possibility of military escalation has prompted a response from members of Congress who argue that any new conflict would require legislative oversight and approval.
Democratic lawmakers have called for passage of a war powers resolution designed to prevent the administration from initiating military action against Cuba without congressional authorization.
Rep. Nydia Velázquez of New York, one of the measure’s lead sponsors, warned that the administration’s approach risks opening another international conflict.
“Trump’s belligerent foreign policy is creating new wars and conflicts across the world. As our country is already embroiled in a new war with Iran, the president has now set his sights on regime change in Cuba,” Velázquez said. “This administration is rushing toward another disastrous war, putting countless American and foreign lives at risk.”
Even as he condemned the humanitarian consequences of sanctions, Türk also called on Cuban authorities to respect civil liberties and release all arbitrarily detained individuals. His statement placed responsibility on both governments to avoid actions that further deepen suffering for civilians.
For now, however, the UN’s most urgent warning centers on the immediate human consequences of the current crisis. Hospitals face shortages, food production continues to decline, humanitarian shipments remain disrupted, and large portions of the island continue to experience lengthy power outages. Human rights officials say those conditions are no longer simply economic hardships but a growing humanitarian emergency affecting millions of people.
“This creates a perfect storm for social and economic deterioration and suffering for the Cuban people,” Türk said.
