Amnesty International published an open letter Tuesday criticising the policies of President Jair Bolsonaro, saying they will lead to more homicides and deny some Brazilians their human rights.
The group said Bolsonaro's "anti-human rights" rhetoric throughout his career is now "being translated into concrete measures and actions that threaten and violate the human rights of all people in Brazil."
The letter outlined measures like Bolsonaro's moves to ease gun laws, a tougher new drug policy and what it said are attempts "to interfere unduly in the work of civil society organisations."
It also said Bolsonaro, who took office January 1, is infringing on the rights of Brazil's indigenous people and communities of the descendants of enslaved people.
"It is an extremely delicate time in the Americas," she said, citing Central Americans in need of protection in the United States and leaders accused of promoting violence and persecuting opponents in Venezuela and Nicaragua.
Bolsonaro's ministry of women, family and human rights responded to Amnesty International, saying they wanted to promote dialogue with the NGO to show that their statements weren't true.
"There was no evidence that any of the accusations are based on data or concrete events," the statement read.
Also on Tuesday, governors from 13 of Brazil's 26 states published a letter protesting the decree that Bolsonaro signed to loosen gun laws. The decree increases annual ammunition purchase limits and gives the right to carry a gun in public without permission for people ranging from the federal police to professions like truckers, elected politicians and journalists.
"We do not think the measures outlined in the decree will help make our states safer. Quite the opposite, these measures will have a negative impact on violence," the governors wrote.
