The tourism balloon caught fire during the flight in early hours, crashing in a forest area in the city of Praia Grande, according to the state fire department.
The city is a popular tourist spot for balloon trips in Brazil. The Santa Catarina government estimates that 25 to 30 hot-air balloons depart daily from Praia Grande in peak season, most of them having capacity to transport as many as 25 people.
Thirteen survivors were taken to hospitals, according to the fire department. A spokesperson of the department told local news outlet CNN Brasil that none of them were with their lives at risk.
In a post on X, Brazilian President Luiz Inacio Lula da Silva expressed solidarity with the families of the victims, saying the federal government was available to local and state forces acting in the case.
