The Trump administration is rolling out what experts describe as the most significant expansion of U.S. sanctions on Cuba in decades.

The administration is attempting what supporters say is the first broad application of Cuba-related secondary sanctions against foreign firms, aiming not only at Havana itself but also at foreign companies and banks that continue doing business with the island’s military-linked economic empire. 

The new framework, established under an executive order signed by President Donald Trump May 1, applies pressure beyond U.S. companies for the first time, threatening foreign firms with sanctions exposure if they continue operating in key sectors of the Cuban economy linked to Grupo de Administración Empresarial S.A., or GAESA.

TRUMP ADMINISTRATION PRESSED TO CLOSE CUBA EMBARGO LOOPHOLE AS OIL SET TO RUN OUT WITHIN DAYS

Supporters say the move closes a loophole that allowed foreign investors to sustain Cuba’s communist regime while the longstanding U.S. embargo largely restricted Americans.

Critics argue the measures risk worsening an already severe humanitarian crisis on the island without meaningfully weakening the government.

"At the top of the month, what the Trump administration did was for the first time extend the application of U.S. sanctions from just prohibiting trade between U.S. firms and U.S. persons and the Cuban island to third-party countries and enablers," Max Meizlish, a former Treasury Department official now serving as a research fellow at the Foundation for Defense of Democracies, told Fox News Digital in an interview.

"For the first time ever in a truly unprecedented fashion, that’s the same logic that the administration is now applying to Cuba," he said.

The sanctions focus heavily on GAESA, a sprawling military-linked conglomerate that analysts estimate controls between 40% and 70% of Cuba’s economy, including tourism, mining, retail, ports and financial services. 

A recent Foundation for Defense of Democracies report authored by Meizlish and Connor Pfeiffer argued that foreign companies doing business in Cuba are effectively helping sustain the regime’s military and political leadership.

The State Department sanctioned GAESA and several affiliated entities in May under the new authorities, opening the door for potential penalties against foreign companies and financial institutions that continue dealings with them after a June 5 wind-down deadline.

Meizlish argued previous sanctions regimes failed because they isolated American companies while allowing foreign actors to continue financing the Cuban state.

"There’s a lot of Spanish firms, for instance, that have invested millions of dollars in luxury hotel properties, villa properties in Cuba that partner with GAESA, all funding this military enterprise at the expense of the Cuban people," he said.

He also pointed to Canadian involvement in Cuba’s nickel and cobalt sectors, saying foreign investment has generated "huge amounts of money for the regime."

"A lot of people think about the U.S. embargo over the years is actually being responsible for a lot of the problems on the Cuban island, but they don't give consideration to the fact that GAESA, this newly sanctioned entity, has been sitting on an estimated $20 billion in assets and cash over the year while depriving the people of Cuba," Meizlish told Fox News Digital.

But critics of the policy warn the economic fallout could land hardest on ordinary Cubans.

William LeoGrande, a longtime Cuba expert at American University, said the May 1 measures represent a major escalation because they specifically target foreign businesses rather than just Americans.

LeoGrande said the new sanctions represent a major escalation because they extend beyond Americans and aim to deter foreign companies from doing business with GAESA by threatening sanctions exposure.

LeoGrande acknowledged the measures could deprive the Cuban government of revenue but argued the broader population is likely to suffer most.

"This would potentially deprive the Cuban government of funds, but the impact will fall mainly on ordinary citizens because it means the government has fewer resources to import food, medicine and fuel," he said.

The debate comes as Cuba faces its deepest economic and humanitarian crisis in years. 

The World Food Programme says food insecurity is worsening amid fuel shortages, inflation and declining access to imported goods, while U.N. officials have warned that electricity shortages and blackouts are disrupting hospitals, vaccination programs and food distribution networks across the island.

LeoGrande also warned tougher sanctions could contribute to another migration crisis.

"Another unintended effect is that by making living conditions in Cuba even more desperate, tougher sanctions could trigger a mass migration like we saw in 1980 or 1994," LeoGrande said.

On background, a U.S. official rejected arguments that American sanctions are responsible for Cuba’s humanitarian crisis.

"The suffering of the Cuban people is not caused by the U.S. embargo but by the Cuban dictatorship’s failed Communist policies and human rights violations," the official told Fox News Digital. "The embargo does not prohibit Cuba’s access to world markets or trade with third countries."

The official added that U.S. law explicitly permits exports of food, medicine and medical equipment to Cuba and accused the regime of hiding "billions in overseas bank accounts instead of investing in electricity, infrastructure and the daily needs of its people."

The debate mirrors longstanding arguments surrounding U.S. sanctions on countries like Iran and Venezuela, where supporters view economic pressure as a tool to weaken authoritarian governments while critics argue regimes often survive and civilians absorb the economic damage.

Meizlish argued sanctions should not be judged simply by whether they immediately topple governments.

"The problem isn’t that the embargo went too far," he said. "It’s that it didn’t go far enough."

Fox News Digital reached out to the Cuban Embassy in Washington for comment but did not receive a response by the time of publication.

Three sisters whose bodies were recovered from the sea near Brighton beach last week have been formally identified as police continue investigating the circumstances surrounding their deaths and their grieving father shares an emotional tribute to his daughters.

Jane Adetoro, 36, Christina Walters, 32, and Rebecca Walters, 31, all from the Uxbridge area of London, were found in the water near Black Rock car park early Wednesday morning, Sussex Police said.

The tragedy has shocked communities in Brighton and London, with the sisters’ grieving father releasing an emotional tribute describing his daughters as "unique and precious."

"Today, with a heart full of sorrow and love, I pay tribute to my beloved daughters — Jane, Christina, and Becky — whose lives ended so tragically far too soon," their father Joseph said in a statement.

"No words can truly describe the pain of losing three daughters in the prime of their lives. Jane, Christina, and Becky were more than daughters to me; they were my joy, my strength, and the beautiful light that filled our family with happiness and love," he added.

Authorities say there is currently no evidence of criminality or third-party involvement, but detectives are continuing extensive inquiries to understand how the women came to be in the water.

Specialist detectives are reviewing hundreds of hours of CCTV footage and tracing the women’s final movements between Tuesday night and Wednesday morning.

Police urged anyone who saw the sisters near Madeira Drive between 10 p.m. Tuesday and 5:30 a.m. Wednesday to come forward.

Chief Superintendent Adam Hays said investigators would "leave no stone unturned" as authorities work to determine what led to the deaths of the three sisters.

"I know this incident has had a profound impact on the local community in Brighton, and across the country, and I’d like to reassure the public we will leave no stone unturned in our investigation to understand exactly what led to the tragic events of that Wednesday morning," Hays said in a statement.

The Superintendent urged privacy for the Walters family in this "terrible tragedy" as the investigation unfolds.

"This investigation will continue in earnest, with Jane, Christina and Rebecca’s family at its center. I would ask that they are given the privacy to come to terms with this terrible tragedy," Hays added.

The sisters' father, Joseph, closed his message in dedication to the spirits of his three daughters:

"Though you are no longer here beside us, your spirits live on in our hearts every day. Love like yours never dies. You will forever remain a part of our lives, our prayers, and our memories," Joseph said.

A 14-year-old boy is dead after allegedly killing at least nine people and wounding 13 more at a Turkish middle school Wednesday, according to media and official reports.

The boy reportedly carried out the violent attack, the second of its kind in as many days in Turkey, with guns belonging to his father, a former police officer, according to Regional Governor Mukerrem Unluer.

"A student came to school with guns that we believe belonged to his father in his backpack. He entered two classrooms and opened fire randomly, causing injuries and deaths," Unluer told reporters, according to multiple media reports.

Eight of the deaths were students, while the other was a teacher, Turkey's Interior Minister Mustafa Ciftci told reporters, per Reuters.

Ciftci was also adamant that this was a "sole incident" and not a terror attack.

The shooting took place at Ayser Çalık Middle School in Turkey's Kahramanmaras region, roughly 140 miles west of the high school where another student killed himself after injuring 16 others in a shooting one day earlier.

Shooting deaths are rare in Turkey, with just over 2.6 per 100,000 residents every year, compared to the U.S.'s 14.5. Gun applicants must be at least 21 years old and go through a rigorous medical clearance and background check process.

Gun acquisition is, however, considerably more expedient for professionals with certain careers, such as law enforcement.

Despite the difficulties, Turkey has now been rocked by two mass shootings in two days. In response, the government has urged citizens not to spread misinformation and to protect the peace.

"Managing the process with sound judgment, protecting societal peace, and particularly ensuring the psychological security of our children are of utmost importance," the country's Ministry of Communications also posted on X.

"It is essential for our media organizations to act with the utmost sense of responsibility in their broadcasting policies," the post continued, adding that "such incidents create a highly fertile ground for disinformation."

Four chief inspectors and four inspector generals have been assigned to an investigation into the incident, the Turkish Ministry of the Interior wrote on X.

A former student injured at least 16 people Tuesday after opening fire with a shotgun inside a high school in Turkey before turning the weapon on himself, officials said. 

The 18-year-old who targeted the vocational high school in Siverek, located in southeastern Turkey, took his own life with the shotgun after he was "cornered by police," Gov. Hasan Sildak said. 

Video taken at the scene showed students sprinting out of a building as law enforcement and first responders arrived. 

The attack left 10 students, four teachers, a school canteen employee and a police officer hurt, according to Sildak, who added that five of the teachers and students were transferred to a hospital in the provincial capital because their conditions were more serious.

The motive for the shooting was unclear. The attacker did not have a criminal record, Sildak said.  

The school had been declared safe and no permanent police officer was assigned to protect it, he added, calling the shooting an "isolated incident." 

Sildak told NTV that the attacker started firing indiscriminately, beginning in the school yard before entering the building, Reuters reported.

One student told the state-run Anadolu Agency that he and a friend jumped out of their classroom window to flee the gunman. 

"He suddenly entered the classroom and fired. He fired four or five times. Two people were hit. He then went into the next classroom," Anadolu quoted Omer Furkan Sayar as saying. "We first threw ourselves to the ground and then two of us jumped out of the window." 

"He didn't say anything, he entered and started to shoot directly," Sayar added.

"The individual was cornered inside the building through police intervention and died after shooting himself," Sildak told reporters, adding that a "comprehensive" investigation into the shooting would be carried out.
