Around 50 girls are being treated in hospital in Burkina Faso after botched circumcisions, or female genital mutilation (FGM), a minister says.
Not all girls who underwent the circumcision have been traced, Minister of Women's Affairs, Laurence Marshall Ilboudo, said.
Two 60-year-old women, along with the parents of some of the girls, have been arrested.
FGM has been illegal in Burkina Faso since 1996.
Offenders face up to three years in prison.
The circumcisions took place in the Kaya area, about 100km (60 miles) north of the capital, Ouagadougou, between 4 and 6 September.
Some of the victims are as young as four years, authorities say.
A dozen girls have been admitted to the Kaya Regional Hospital and 38 to the Chiphra Protestant Hospital in the capital.
Some of the girls had suffered serious complications, Dr Dieudonne Ouedraogo told the BBC.
