The U.S. State Department said on Friday it was taking action to dismantle what it described as a sophisticated network that used deception and intermediary companies to obtain advanced equipment for Iran’s defense sector in violation of American sanctions.

According to State Department spokesperson Tommy Pigott, the network allegedly defrauded dozens of U.S. technology firms and secured millions of dollars’ worth of equipment, including spectrum analyzers and security detection devices with potential military applications.

U.S. officials said the operation relied on fraudulent websites designed to resemble legitimate American companies. The network allegedly used intermediaries in Dubai to receive shipments before transferring the equipment to Iran, circumventing existing sanctions restrictions.

The State Department identified Ali Majd Sepehr as the individual leading the network. Officials did not disclose the names of the affected American companies or provide details on the quantity of technology allegedly transferred.

The sanctions announcement comes as Washington increases efforts to disrupt financial and logistical channels linked to Iran’s military establishment. On Thursday, the State Department offered a reward of up to $15 million for information leading to the disruption of financial mechanisms associated with the Islamic Revolutionary Guard Corps and its affiliated branches.

The move also coincides with high-stakes diplomatic discussions between Washington and Tehran aimed at ending the conflict that began earlier this year. The White House said on Friday that President Donald Trump would approve an agreement only if it fully satisfies U.S. requirements, underscoring uncertainty surrounding the negotiations.

The latest sanctions signal that the United States intends to maintain economic and legal pressure on Iran’s defense procurement networks even as diplomatic efforts continue.

In a statement posted on Truth Social, Trump said the operation targeted Abu-Bilal Al-Minuki, whom he identified as the second-in-command of Daesh globally. Trump said the mission was conducted jointly with Nigerian forces following intelligence tracking the militant’s activities across Africa.

“Brave American forces and the Armed Forces of Nigeria flawlessly executed a meticulously planned and very complex mission,” Trump said, adding that Al-Minuki “will no longer terrorize the people of Africa, or help plan operations to target Americans.”Trump did not specify where the operation occurred or whether it involved airstrikes, ground forces or drone attacks.

Nigerian authorities had not immediately issued a public statement detailing the mission.The United States sanctioned Al-Minuki in 2023, identifying him as a senior Daesh figure based in the Sahel region and part of the organization’s General Directorate of Provinces, the administrative structure responsible for coordinating operations and financing across multiple regions.

According to the US State Department, Al-Minuki played a role in providing operational guidance and funding support for Daesh affiliates operating in Africa and beyond.Nigeria has faced escalating militant violence from regional branches linked to Daesh as well as rival Islamist group Boko Haram.

Nigerian security forces have also been engaged in operations against heavily armed criminal gangs known locally as “bandits.”Washington has increased military cooperation with Nigeria since late 2025 amid growing US concerns about the expansion of Islamist insurgencies across West Africa and the Sahel.

On Christmas Day last year, US and Nigerian forces conducted joint airstrikes in Sokoto State targeting fighters from the Islamic State in the Sahel Province, a Daesh affiliate active across parts of Niger and northwestern Nigeria.

Since then, hundreds of US personnel have reportedly been deployed to Nigeria to assist with intelligence sharing, military training and counterterrorism coordination.

Trump thanked the Nigerian government for what he described as its “partnership” in the latest operation, saying the removal of Al-Minuki had significantly weakened Daesh’s international network.

Rubio, traveling with President Donald Trump during a visit to China, said Cuba’s deepening economic turmoil stemmed from structural failures and corruption rather than US sanctions, which Havana has long blamed for shortages and financial distress.“It’s a broken, nonfunctional economy, and it’s impossible to change it,” Rubio told Fox News aboard Air Force One.

“I don’t think we’re going to be able to change the trajectory of Cuba as long as these people are in charge in that regime.”Cuba has been grappling with severe economic disruption and energy shortages, with authorities reporting that around 65% of the island experienced electricity blackouts on Tuesday.

The US State Department publicly renewed the $100 million assistance proposal, saying the package would include humanitarian support and funding aimed at expanding “fast and free” Internet access across the island.

“The regime refuses to allow the United States to provide this assistance to the Cuban people,” the department said in a statement, adding that Cuban authorities would be accountable if they rejected “critical life-saving aid.”Washington last week imposed new sanctions targeting key entities within Cuba’s state-controlled economy and foreign partners linked to the sector.

Trump has recently intensified pressure on leftist governments in Latin America and has suggested Cuba could become a future target of broader US strategic efforts after the removal of Venezuelan leader Nicolas Maduro earlier this year.

Cuban authorities rejected Rubio’s characterization of the crisis and blamed US restrictions for worsening fuel shortages and economic instability.President Miguel Díaz-Canel said the worsening conditions were caused by what he described as a US “energy blockade,” accusing Washington of threatening countries supplying fuel to Cuba with punitive tariffs.

Foreign Minister Bruno Rodríguez Parrilla dismissed Rubio’s claims that Havana had rejected the aid proposal, calling the assertion “a lie” and questioning whether the offer was intended to undermine Cuban sovereignty.

Cuba has witnessed a series of small but increasingly visible protests in recent months as residents face prolonged blackouts, fuel shortages and rising economic hardship.

Witnesses told AFP that demonstrators in parts of Havana banged pots and pans and demanded electricity be restored following new power outages.Cuba’s fuel imports have sharply declined since the United States moved earlier this year against Venezuela’s leadership, reducing energy support from Caracas.

Since then, only one Russian oil tanker has reportedly reached the island.The Trump administration previously provided $6 million in humanitarian aid to Cuba through Catholic Church-linked charities, which have historically acted as intermediaries between Washington and Havana.

The U.S. Treasury Department said Iraqi Deputy Oil Minister Ali Maarij Al-Bahadly used his government position to help divert oil revenues to the Iranian government and affiliated militias.In a statement, the Treasury alleged Al-Bahadly facilitated the sale of oil “for the benefit of the Iranian regime and its proxy militias in Iraq.”

Iraq’s oil ministry and Al-Bahadly did not immediately respond to requests for comment.The sanctions were announced as Washington and Iran moved closer to a temporary arrangement aimed at halting ongoing hostilities, although key disputes between the two sides remain unresolved.

The Treasury Department also imposed sanctions on three senior leaders linked to the Iran-backed militias Kata’ib Sayyid Al-Shuhada and Asa’ib Ahl Al-Haq, groups Washington has previously accused of threatening U.S. interests and regional stability.

“Treasury will not stand idly by as Iran’s military exploits Iraqi oil to fund terrorism against the United States and our partners,” U.S. Treasury Secretary Scott Bessent said in a statement.Under U.S. sanctions rules, any assets held in the United States by the designated individuals are frozen, while U.S. citizens and entities are generally prohibited from conducting transactions with them.

The move follows comments in March by Iraqi Oil Minister Hayan Abdel-Ghani, who said Iranian oil tankers intercepted by U.S. forces in the Gulf had been operating with forged Iraqi documentation. Tehran denied those allegations.

The sanctions underscore Washington’s continuing efforts to curb Iran’s regional financial networks while maintaining parallel diplomatic contacts over de-escalation efforts in the wider Middle East conflict.

The latest sanctions highlight Washington’s continued efforts to disrupt Iran’s regional financial and logistical networks while simultaneously pursuing diplomatic contacts aimed at containing wider conflict across the Middle East.

A recent escalation in US policy toward Cuba is disrupting longstanding international medical programmes, with potential consequences for healthcare systems across Latin America and the Caribbean.

The measures, which target the deployment of Cuban doctors abroad, are part of broader economic and diplomatic pressure on Havana, a country that has been under US sanctions for decades.Cuba’s overseas medical missions have historically been a central component of its international engagement and a significant source of revenue.

Since the 1959 revolution, the Cuban government has deployed medical professionals to countries facing shortages, initially responding to crises such as the 1960 earthquake in Chile. Over time, these efforts evolved into formal bilateral agreements, with Cuban doctors providing services in underserved regions across Latin America, the Caribbean, and beyond.

According to Tiago Rogero, South America correspondent for The Guardian, these programmes have become increasingly constrained due to US pressure on host countries. Washington has argued that the arrangements amount to exploitative labour practices, citing the Cuban state’s retention of a portion of doctors’ earnings.

While some testimonies from medical personnel have supported claims of exploitation, Rogero noted that this does not represent the majority view among those involved. Analysts cited in his reporting suggest that financial considerations specifically limiting revenue flows to the Cuban government—are a central factor behind the policy.

The withdrawal of Cuban medical personnel is already affecting healthcare provision in several countries. A number of governments have ended their agreements with Cuba, in some cases under pressure linked to US sanctions mechanisms such as financial restrictions and visa policies. These measures have reduced the availability of healthcare workers in regions that were already facing shortages.

Cuban doctors have played a significant role in filling gaps in national health systems, particularly in remote or low-income areas where local capacity is limited. In countries such as Brazil, they have been deployed to underserved communities, often in roles that domestic practitioners were unwilling or unable to fill.

Their presence has been part of a broader strategy sometimes referred to as “medical diplomacy,” through which Cuba has combined healthcare assistance with international cooperation.Beyond their immediate service delivery, Cuban medical programmes have also included training initiatives for foreign students in Cuban institutions.

This has contributed to building healthcare capacity in partner countries, although such efforts typically require long-term investment before yielding results.The current policy shift is raising concerns among healthcare professionals and development experts about the absence of alternative arrangements.

Rogero reported that non-governmental organisations and local practitioners anticipate a worsening of healthcare access in affected regions. “Most of these countries do not have enough doctors of their own,” he said, adding that the termination of Cuban programmes is not being matched by new support mechanisms.

The policy comes in the context of a broader reduction in US development assistance. The dismantling of the United States Agency for International Development (USAID), which previously funded health and development programmes in Latin America, has further limited available resources.

Observers note that this combination reduced aid and restrictions on third-party assistance—may intensify existing vulnerabilities in public health systems.The geopolitical dimension of the policy is also evident. US sanctions have long been used as a tool of foreign policy toward Cuba, and recent measures, including tighter fuel restrictions, indicate an expansion of pressure.

While the stated rationale focuses on labour conditions within the medical missions, analysts suggest the policy aligns with broader efforts to constrain the Cuban state economically.For recipient countries, the immediate concern remains service continuity. Healthcare systems in parts of Latin America and the Caribbean rely heavily on external support to address shortages in personnel and infrastructure.

The removal of Cuban doctors is expected to disproportionately affect rural and low-income populations, where access to medical care is already limited.Rogero emphasised that the impact will be most acute among vulnerable groups. “How will they cope now without the few doctors they had?” he said, pointing to the lack of contingency planning. In many cases, Cuban medical teams represented the primary or sole source of healthcare provision in certain communities.

The situation underscores the interconnected nature of global health systems and the role of international cooperation in addressing disparities. As policy decisions reshape these arrangements, the consequences are likely to be felt most strongly at the local level, where healthcare access depends on sustained and coordinated support.

Treasury Secretary Scott Bessent said the administration had cautioned governments and banks that continued transactions involving Iranian oil could trigger punitive measures. “If you are buying Iranian oil, that if Iranian money is sitting in your banks, we are now willing to apply secondary sanctions,” he told reporters at the White House.

The warning comes as the U.S. enforces a naval blockade on Iran that began earlier this week, with officials saying they expect the move to curb purchases by key buyers, particularly China, which has accounted for the majority of Iran’s seaborne oil exports.

Bessent said the Treasury had contacted two Chinese banks, warning that they could face sanctions if evidence shows Iranian funds moving through their systems. China’s embassy in Washington did not immediately respond to requests for comment.

Separately, the U.S. Treasury announced sanctions targeting Iran’s oil transportation network, including more than two dozen individuals, companies and vessels, as part of a broader effort to disrupt the country’s energy exports.

The measures follow the administration’s decision not to renew a 30-day sanctions waiver issued on March 20 that had allowed Iranian oil shipments already at sea to reach global markets.

The waiver, which Bessent said facilitated the delivery of about 140 million barrels, is set to expire on April 19.Washington has also allowed a similar waiver covering Russian oil shipments to lapse, reinforcing its broader sanctions enforcement strategy.

U.S. officials said letters had been sent to jurisdictions including China, Hong Kong, the United Arab Emirates and Oman, identifying financial institutions allegedly linked to Iranian transactions and warning of potential enforcement actions.

The steps are part of what the administration has described as a “maximum pressure” campaign aimed at curbing Iran’s oil revenues and limiting its ability to finance regional activities.

The move, reflected in an update by the Office of Foreign Assets Control, effectively removes restrictions that had limited Rodríguez’s ability to engage with U.S. companies and investors, and underscores Washington’s recognition of her as a legitimate governing authority.

Rodríguez said the decision could open a path toward improved bilateral relations. In a statement posted on her Telegram channel, she described the move as a step toward “normalizing and strengthening relations” and expressed hope that broader sanctions on Venezuela would eventually be lifted to enable deeper cooperation.

The policy change follows the Jan. 3 capture of Maduro and his wife in Caracas by U.S. forces. Both were transferred to New York to face drug trafficking charges and have pleaded not guilty.

Their detention prompted a political transition in which Venezuela’s ruling-party-aligned Supreme Court declared Maduro’s absence temporary and installed Rodríguez as acting president.

Rodríguez, who had previously been sanctioned by Washington during Donald Trump’s first administration, was among senior Venezuelan officials targeted in 2018 for their alleged role in undermining democratic processes after a widely disputed election. Her brother, Jorge Rodríguez, and other members of Maduro’s inner circle were also designated at the time.

Despite those earlier measures, the current administration has opted to engage directly with Rodríguez following Maduro’s removal. U.S. officials have backed her role in implementing a phased plan to stabilize the country’s political and economic system, including outreach to foreign investors and commitments to increased transparency and international arbitration.

The administration has also taken broader steps to ease restrictions on Venezuela’s economy. In March, the Treasury authorized state oil company Petróleos de Venezuela S.A. to resume direct sales to U.S. buyers and access global markets, reversing years of tight sanctions on the country’s energy sector.

In parallel, U.S. authorities have formally recognized Rodríguez as the sole head of state in an ongoing civil case in federal court, further consolidating her standing in Washington’s policy framework.Maduro, however, remains Venezuela’s legal president under the country’s institutional structure.

The Supreme Court’s ruling allows Rodríguez to govern for an initial 90-day period, which is set to expire Friday, with a possible extension to six months subject to approval by the National Assembly, which is controlled by the ruling party and led by her brother.

The developments highlight an evolving U.S. approach toward Venezuela, balancing legal proceedings against Maduro with pragmatic engagement aimed at restoring economic activity and political stability in the oil-rich nation.

The vessel, the Anatoly Kolodkin, operating under U.S. sanctions, is the first Russian oil delivery to Cuba since January. Its arrival follows a decision by Donald Trump to permit the cargo on humanitarian grounds, avoiding a potential standoff with Moscow while easing acute shortages that have led to blackouts and fuel rationing.

Residents expressed cautious optimism as the tanker approached the Supertanker Base in Matanzas, a key energy hub east of Havana. Many said the shipment would provide temporary respite but fall short of addressing systemic shortages.

Cuba has faced repeated nationwide blackouts since 2024, alongside persistent scarcities of fuel, food and medicine. The latest delivery is expected to be processed over several weeks before refined products enter circulation.

Energy expert Jorge Pinon of the University of Texas at Austin estimated the crude could yield around 250,000 barrels of diesel, enough to meet demand for roughly 12 days, underscoring the limited scale of the relief. Fome Cubans welcomed the shipment as urgently needed support.

Others described it as insufficient given the depth of the crisis, calling it a symbolic gesture with minimal economic impact.The government is expected to prioritize allocation between electricity generation and transportation, both critical sectors strained by fuel shortages.

Analysts say the oil is unlikely to be used in Cuba’s aging thermoelectric plants, which rely primarily on domestically produced crude.Russia signaled its continued backing for Havana, with Kremlin spokesman Dmitry Peskov stating Moscow viewed assistance to Cuba as a responsibility.

He added that Russia and the United States had been in contact regarding the shipment.Washington maintained that its broader sanctions policy remains unchanged.

The White House described the waiver as a case-by-case humanitarian decision, even as Trump reiterated criticism of Cuba’s leadership and downplayed the shipment’s long-term impact.Cuba’s energy outlook has worsened since the disruption of supplies from Venezuela earlier this year, intensifying reliance on external partners.

Efforts to secure alternative shipments, including discussions involving Mexico, have yet to yield sustained flows sufficient to stabilize the grid.

Speaking to reporters aboard Air Force One, Trump said Washington would not oppose a shipment from Russia or other countries if intended to alleviate shortages. “If a country wants to send some oil into Cuba right now, I have no problem whether it’s Russia or not,” he said.

Shipping data cited in reports shows a tanker carrying roughly 730,000 barrels of oil nearing Cuba’s eastern coast, with an expected arrival in Matanzas. The vessel is expected to deliver fuel that could yield about 180,000 barrels of diesel, enough to meet the country’s demand for more than a week.

The tanker, identified as the Anatoly Kolodkin, is under sanctions imposed by the United States, the European Union and the United Kingdom following the war in Ukraine.

Trump’s remarks come despite his administration’s intensified efforts to restrict oil flows to Cuba in a bid to pressure its government. He has previously threatened punitive tariffs on third countries supplying oil to the island.

The blockade has contributed to widespread fuel shortages, with reports of prolonged blackouts and disruptions to public transport and healthcare services across Cuba.Cuba has long been a focal point of strategic competition between the United States and Russia.

Trump dismissed suggestions that allowing the shipment would benefit Russian President Vladimir Putin, saying the delivery would have limited impact beyond addressing immediate needs.

He said he would prefer allowing fuel deliveries to ease hardship for civilians, citing the need for electricity, heating and cooling as essential services.
