Inter-American Commission on Human Rights called on country to implement strategies to prevent and prosecute femicides.
With a population of more than 200 million, Brazil has only 74 shelters for victims of domestic violence, according to Human Rights Watch.
In Brazil, those women killed are often shot dead in their own homes at the hands of current or former boyfriends who have a history of domestic abuse, the IACHR said.
“The commission notes with concern that in most cases, the murdered women had previously denounced their aggressors, faced serious acts of domestic violence or suffered previous attacks or attempted homicides,” the IACHR said.
Femicides are not an “isolated problem” but reflect “sexist values deeply rooted in Brazilian society”, the IACHR said.
