Residents fleeing clashes between rival armed groups gathered on Monday near routes leading to Toussaint Louverture International Airport after gunmen attacked neighborhoods, burned homes and expanded fighting across parts of Port-au-Prince, according to residents and local authorities.

Monique Verdieux, 56, said she escaped after armed men set houses ablaze in her neighborhood, leaving her separated from relatives who fled in different directions.“I am now sleeping in the street,” Verdieux said, adding that returning home was too dangerous.

The latest violence underscores the deepening collapse of public security in Haiti, where gangs have steadily expanded territorial control since the July 2021 assassination of President Jovenel Moïse. Authorities estimate criminal groups now control more than 90% of Port-au-Prince, while kidnappings, looting and sexual violence have spread beyond the capital into rural regions.

Haiti has remained without an elected president since Moïse was killed at his private residence, contributing to a prolonged political vacuum and weakening state institutions.Security concerns near the airport have also alarmed major businesses operating in the country.

Haitian rum producer Rhum Barbancourt and two of the nation’s largest bottling companies warned in a joint statement on Sunday that worsening insecurity and damaged roads around the airport were hampering patrols by security forces and disrupting commercial activity.

“The government’s response has been largely insufficient,” the companies said, adding that deteriorating road conditions near the airport had further undermined efforts to secure the area.Operations at the airport are now severely restricted, according to the statement.

The violence has intensified despite the gradual deployment of an international security mission backed by the United Nations. In April, the first contingent of foreign troops linked to the mission arrived in Haiti to support local police in combating armed groups.

The U.N. Security Council approved plans in September for a multinational force of 5,550 personnel, although the full contingent has yet to be deployed.

Troops from Chad are among those reported to have arrived in the country.According to the International Organization for Migration, gang violence has displaced more than 1.4 million people across Haiti.

The agency said roughly 200,000 displaced people are living in overcrowded and underfunded shelters in the capital.

The outage, described by the state-run utility as a “total disconnection” of the national system, was triggered by a failure at a thermoelectric power unit that caused a cascading breakdown across the grid. The Cuban Electric Union said micro-grids were being activated to restore electricity to critical services such as hospitals and water treatment facilities.

Cuba’s power generation relies on eight thermoelectric plants, many operating for more than four decades and prone to repeated breakdowns and maintenance shutdowns. The system has struggled to meet demand, resulting in prolonged daily blackouts.In Havana, outages can last up to 15 hours, while in other parts of the island they can exceed 40 hours, according to local accounts.

As night fell during the latest outage, much of the capital was left without lighting, with residents relying on mobile phone flashlights to navigate streets.Some businesses in tourist areas remained open using generators, but residents described growing frustration with the frequency of disruptions.

“This is becoming unbearable,” said one Havana resident, reflecting widespread fatigue over recurring outages.

The energy crisis has intensified since disruptions to fuel supplies earlier this year. No oil shipments have reached Cuba since January 9, placing additional strain on electricity generation and forcing cutbacks in sectors including aviation and tourism.

The situation has been compounded by geopolitical tensions. U.S. President Donald Trump has threatened tariffs on countries supplying oil to Cuba, while also making remarks supporting political change in Havana. Cuban President Miguel Díaz-Canel has warned that any external aggression would be met with resistance.

Maritime tracking data indicated that tankers carrying Russian oil and diesel may be en route to the island, though their status remains unclear.

The repeated outages come amid broader shortages of food, medicine and basic goods, contributing to rising public discontent. Demonstrators vandalised a provincial office of the ruling Communist Party last weekend, underscoring growing tensions.

Despite the disruption, some residents continued working under difficult conditions. Small shopkeepers operated by flashlight, while fishermen cast lines along the darkened coastline, reflecting the persistence of daily life even as the energy crisis deepens.
