PORT-AU-PRINCE, Haiti (AP) — Dozens of people swam and waded across Haiti's longest river on Wednesday in a desperate attempt to flee gangs that launched a fresh attack on a city in the country's central region that has been under siege for almost a week.

The onslaught in rural areas of Petite Rivière began before dawn, according to Bertide Horace, spokesperson for the Commission for Dialogue, Reconciliation and Awareness to Save the Artibonite, an activist group.

“Gangs are invading the city everywhere,” she told The Associated Press by phone. “There are people trapped in their homes who can’t leave, and the guys are setting fire wherever they go.”

Videos posted on social media showed people balancing their belongings on their head or holding them aloft as they crossed the Artibonite River. A couple of boats ferried the few who could afford one.

Another video showed the bodies of several people, including that of a young boy, sprawled behind a school where gangs were killing residents in Petite Rivière. A woman screamed in anguish in the background as the man filming began to cry.

Horace blamed the Gran Grif gang for the ongoing attack, adding that the Viv Ansanm gang coalition was providing reinforcements.

A policeman who asked not to be identified because he was not authorized to speak to the media said officers on Wednesday were fighting gangs at the Crête-à-Pierrot fort, site of a key battle during the Haitian Revolution.

Gunmen first attacked Petite Rivière on April 24, and they have seized full control of the town’s northern region, she said.

“The police are still fighting, but they have already taken control of a good part of the city,” Horace said.

Several people have been killed, including an 11-year-old child, Horace said.

Haiti's heartland under attack

Gran Grif is the largest gang to operate in the central Artibonite region. It was blamed for an attack in the central town of Pont-Sondé in October 2024, where more than 70 people were killed in one of the biggest massacres in Haiti's recent history.

Gran Grif was formed after Prophane Victor, a former member of Parliament who represented Petite Rivière, began arming young men in the region, according to a U.N. report.

The attack on Petite Rivière comes weeks after the Canaan and 400 Mawozo gangs struck other towns in the Artibonite region, according to the U.N. political mission in Haiti.

The gangs in late March seized control of most of Mirebalais, where gunmen stormed a local prison and released more than 500 inmates. Gangs also raided the nearby town of Saut d'Eau, which attracts thousands for an annual Vodou-Catholic pilgrimage.

The U.N. mission said in a report released Wednesday that while the attacks began on March 21, prompting residents to call for help on social media, the government did not deploy specialist police units until March 31.

At least 15 people were killed in Mirebalais, including two Catholic nuns. Most people were shot inside their homes or on the street as they tried to flee, according to the report.

The U.N. mission noted that the Canaan gang leader had posted a video on social media on March 20 warning of “an imminent attack” on Mirebalais.

The mission said gangs struck to dismantle a barricade that a self-defense group had erected to stop gunmen from entering the heart of Mirebalais and to block the smuggling of weapons and drugs, presumably from the neighboring Dominican Republic, which shares the island of Hispaniola with Haiti.

A trail of violence

Overall, more than 1,600 people were killed from January to March in Haiti, including at least 35 children. Another 850 people were injured, according to the U.N. report. Most of the killings and injuries were reported in the capital, Port-au-Prince, with 85% of it controlled by gangs.

Gangs were responsible for 35% of the deaths and injuries, while police operations and executions were responsible for 56%. The rest were blamed on vigilante movements.

During that time frame, at least 161 people were kidnapped, with 63% of those cases reported in Artibonite, according to the report.

Haiti's National Police are fighting gangs with help from a U.N.-backed mission led by Kenyan police that deployed last year. However, the mission has struggled as it remains underfunded and understaffed, with roughly 1,000 personnel out of the 2,500 envisioned.
