The Cuban government said the meeting occurred “in a context marked by the complexity of bilateral relations” and was intended to contribute to dialogue between the two countries after months of escalating tensions.

The CIA did not immediately respond to requests for comment.The talks came one day after Cuba’s energy minister, Vicente de la O Levy, said the country had exhausted its reserves of diesel and fuel oil, leaving the national power grid in what he described as a “critical” condition.

“We have absolutely no fuel oil and absolutely no diesel,” Levy said on state media on Wednesday, acknowledging the country had no remaining reserves as prolonged blackouts intensified across the island.

Residents in several districts of Havana staged protests late Wednesday, chanting “turn on the lights,” banging pots and pans and setting fire to piles of rubbish as electricity outages stretched to as long as 22 hours in some areas.

Cuban authorities blamed the shortages on what they described as a U.S. blockade that has sharply restricted the island’s ability to import fuel and financing. Washington imposed additional measures targeting Cuba’s energy sector in January, further straining supplies.

In its statement, Havana reiterated that Cuba did not pose a threat to U.S. national security and rejected allegations related to foreign military or intelligence activity on the island, including claims regarding a Chinese presence.

“Havana has never supported any hostile activity against the United States, nor will it permit actions against any other nation to be carried out from Cuba,” the statement said.Relations between Washington and Havana have deteriorated significantly in recent months.

U.S. President Donald Trump has expanded sanctions on the communist-run island and publicly floated the possibility of greater U.S. control over Cuba’s affairs, while Cuban officials have accused Washington of deliberately worsening humanitarian conditions.

U.S. Secretary of State Marco Rubio recently renewed an offer of $100 million in aid on the condition that distribution be handled through the Catholic Church rather than the Cuban government.

Cuban President Miguel Díaz-Canel said in a post on X that the humanitarian situation could be alleviated more effectively if the United States eased sanctions and restrictions on the island.

“The damage could be eased in a much simpler and faster way by lifting or relaxing the blockade,” Diaz-Canel said, adding that Cuba would not obstruct humanitarian assistance if Washington demonstrated “true willingness” to provide aid.

Despite mounting tensions, diplomatic engagement between the two governments has continued. A senior-level bilateral meeting took place in Havana on April 10, marking the first landing of a U.S. government aircraft in the Cuban capital since 2016.

Large parts of Islamabad have been effectively shut down under sweeping security measures imposed ahead of expected US-Iran talks, leaving residents cut off from work, transport and essential services as uncertainty persists over whether the negotiations will take place.

Public transport has been suspended, offices closed and workers instructed to operate from home where possible. Streets in the capital remain largely empty, with movement restricted and security personnel from the army and police deployed across key routes.

For many residents, the situation has drawn comparisons with restrictions imposed during the COVID-19 pandemic, though officials say the current measures are linked to security preparations for high-level diplomatic engagements.

The restrictions have also extended to neighboring Rawalpindi, intensifying disruption across the twin cities that form a major administrative and economic hub. While authorities have framed the measures as necessary to ensure safety for visiting delegations, delays and uncertainty surrounding the talks have heightened public frustration.

Workers living in temporary accommodations have been among the hardest hit. Following a government directive, many hostel residents were required to vacate their rooms on short notice, forcing thousands to seek alternative arrangements. Some returned to their hometowns, while others relied on friends or colleagues for temporary shelter.

Areej Akthar, a health officer at the Pakistan Institute of Medical Sciences, said the sudden eviction created confusion and distress. She was able to travel back to her village, approximately three hours away, but said many others lacked similar options. According to her account, workers from distant regions struggled to find accommodation as they waited for clarity on when restrictions might be lifted.

With public transport suspended, many displaced workers have been unable to return to their jobs. Akthar described the situation as restrictive, noting that those dependent on shared housing could not afford alternative arrangements.

The uncertainty surrounding the duration of the lockdown has compounded concerns, particularly for those in lower-income groups.Economic pressures have intensified as the restrictions intersect with broader regional developments.

Since late February, escalating tensions involving the United States, Israel and Iran have disrupted global energy markets. Iran’s closure of the Strait of Hormuz, a critical route for oil and gas shipments, has contributed to supply shortages affecting countries including Pakistan.

In Islamabad, fuel shortages have led to power outages lasting several hours daily, while limited availability of cooking gas has forced many restaurants to shut down. Businesses that had managed to continue operations amid the energy constraints have now been closed due to the security lockdown, further reducing economic activity.

Transport workers have also reported sharp declines in income. Taxi drivers in the capital said their earnings have dropped by about half as movement restrictions reduced demand. Daily wage earners have been particularly vulnerable, with many unable to work for several consecutive days.

Muhammad Zubair, a labourer in Islamabad, said the loss of income had immediate consequences for his household. Speaking from a roadside location, he questioned the benefits of hosting high-level diplomatic talks when basic economic needs remain unmet. He said that without work, he could not provide food for his family, reflecting concerns widely shared among informal sector workers.

The disruption has extended beyond employment to education and administrative processes. Authorities have relocated civil service examinations for more than 1,200 candidates to Lahore, approximately 370 kilometers from the capital. Candidates expressed concern over the additional financial burden and logistical challenges associated with travel.

Yasir Mushtaq, one of the candidates, said he would need to borrow money to attend the examination. He also highlighted the difficulties faced by female candidates, noting that some may be unable to travel without family accompaniment and could therefore miss the opportunity to sit for the exams.

Officials have acknowledged the scale of disruption, with one senior figure describing the situation as a nationwide slowdown linked to external geopolitical developments. The official said the country appeared to be in a holding pattern, awaiting decisions from Washington and Tehran regarding the proposed negotiations.

Despite the extensive preparations, uncertainty remains over whether the talks will proceed as planned. In the absence of a confirmed timeline, residents continue to face restrictions with no clear indication of when normal activity will resume.The prolonged lockdown has raised questions about the balance between security requirements and economic sustainability.

While authorities have not publicly indicated a timeline for lifting restrictions, the ongoing disruption is likely to deepen challenges for vulnerable populations already affected by rising energy costs and reduced economic opportunities.

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.
