Both the CPD and UN said that the killings took place in the capital’s western coastal neighbourhood of Cite Soleil.
Reached by telephone by AFP, a resident confirmed the attacks and said that his 76-year-old father was among the victims.
“The bandits set fire to his body. The family cannot even organise a burial for him since we were unable to recover the body,” he told AFP on condition of anonymity so as not to compromise the safety of other relatives.
“I also fear for their lives,” he said. “I will try to get them out.”
“The gang’s soldiers were responsible for identifying victims in their homes to take them to the chief’s stronghold to be executed,” the CPD said.
“Reliable sources within the community report that more than a hundred people were massacred, their bodies mutilated and burned in the street,” it said.
One of the organisation’s leaders, Fritznel Pierre, told Radio Magik 9 in an interview that the number of casualties was not exhaustive, as the area was difficult to access.
He reported that henchmen had hunted down old people and voodoo followers living in the Wharf Jeremie section of Cite Soleil between Friday evening and Saturday.
“Motorcycle taxi drivers who tried to flee with targeted people were also executed,” he said.
Voodoo was brought to Haiti by African slaves and is a mainstay of the country’s culture. It was banned during French colonial rule and only recognised as an official religion by the Haitian Government in 2003.
While it incorporates elements of other religious beliefs, including Catholicism, voodoo has been historically attacked by other religions.
Haiti has suffered from decades of instability but the situation escalated in February when armed groups launched coordinated attacks in the capital to overthrow then-Prime Minister Ariel Henry.
Gangs now control 80% of the city. Despite a Kenyan-led police support mission, backed by the United States and UN, violence has continued to soar.
The UN chief called on authorities to conduct a thorough investigation into the weekend massacre and also reiterated calls for more international support to assist Haitian police in their battle against the gangs.
More than 700,000 people are internally displaced in Haiti, half of them children, and the latest killings bring the death toll this year in the country to 5000 people, according to the UN.
