At least 41 young men have died as a result of circumcision procedures as part of traditional initiation activities in South Africa in November and December, authorities said Tuesday.

South Africa’s Traditional Affairs Minister Velenkosini Hlabisa told local broadcasters Tuesday that 41 initiates died during this year’s summer initiation. He blamed negligence on the part of both the initiation schools, including registered ones, and parents for not adhering to safety standards and medical advice.

Hlabisa said some of the unproven advice often given to the young men is to avoid drinking water in order to heal faster.
