At least 110 people were massacred in a slum in Haiti's capital, Port-au-Prince, after a gang leader appeared to have targeted people he suspected of causing his child's illness through witchcraft, a human rights group said Monday. 

The National Human Rights Defense Network (RNDDH), based in the capital, said a local gang leader, Monel "Mikano" Felix, ordered the killings after a voodoo priest told him that elderly people in Wharf Jeremie, a district of the capital's notorious Cite Soleil slum, had cursed his son.

Gang members then reportedly butchered at least 60 people on Friday and another 50 on Saturday with knives and machetes. Most of the victims were reportedly voodoo followers over the age of 60.

The New York Times said that a local resident had confirmed the reports by the RNDDH and the Combine for Peace and Development (CPD) charity.
