Residents and officials told local media the attack began in the early hours of Sunday in rural communities around Jean-Denis, and continued into the early hours of Monday, with gang members storming the area and setting homes on fire.

The Defenseurs Plus rights ​group said it estimated 6,000 people had been displaced by the violence.

The UN estimated that more than 2,000 people left their ​homes in the days following raids by armed gangs nearby.

Police initially reported 16 dead and 10 injured, while ⁠a preliminary report from civil protection authorities said 17 had died and 19 were wounded, mostly men.

A spokesperson for the UN Secretary-General told ​a press briefing that the organisation’s office in Haiti, BINUH, was closely monitoring the events and that estimates ranged from 10 to 80 people killed. He ​called for a thorough investigation.

“The lack of a security response and the abandonment of Artibonite to armed groups demonstrate a complete abdication of responsibility by the authorities,” Defenseurs Plus said in a joint statement with the Collective to Save the Artibonite.

An audio message circulated on social media was attributed to Gran Grif leader Luckson Elan.

​In the message, Elan appears to say the attack was retaliation for attacks on their base in Savien by a rival armed group.

The ​Artibonite department, a key agricultural area, has seen some of Haiti’s worst violence. Gang conflict has extended beyond the capital, Port-au-Prince, despite more aggressive policing and promises of more ‌foreign ⁠support for Haiti’s security forces.

Ongoing operation

Haiti’s National Police said it deployed three armoured vehicles, which were slowed by holes that gang members had dug in the road.

Officials said the armed group was fleeing the area when police arrived, and several houses were already burned down.

The injured were then taken to a local hospital, and the dead to two morgues, said police, adding they have launched an operation to track down the gang members ​who fled.

Defenseurs Plus estimated 50 houses ​were burned down.

Close to 20,000 ⁠people have been killed in Haiti since 2021, according to a recent UN report, with the death toll rising each year, as increasingly independent and powerful armed gangs have clashed with security forces and local vigilante groups.

Gran Grif ​and Viv Ansanm, which groups hundreds of gangs in the capital, have been designated terrorist organisations ​by Washington.

The ⁠groups have been accused of mass killings, gang rapes, arson, theft and trafficking guns, drugs and organs.

This month, the US offered a reward of up to $3 million for information on their financial activities.

The weekend’s attack marks the latest of a series of massacres in the area, largely attributed to Gran Grif.

In ⁠October 2024, ​a Gran Grif attack on the nearby town of Pont-Sonde left 115 dead, as armed ​men shot residents door to door.

More than 1.4 million people - around 12% of the Caribbean’s most populous nation - have been displaced by the conflict with armed gangs, worsening an economic crisis ​and access to food.
