VICE heads to the city of Medan in Northern Indonesia to check out the world’s largest mass circumcision, officially known as “Khitanan Massal 3000.” Khitan, or circumcision, is a tradition upheld by Islamic law; often a public event, it is a celebrated and widely practiced Muslim tradition.

Indonesia has the largest population of Muslims in the world and is home to influential missionary organizations that keep Islamic culture and tradition alive by sponsoring community events such as mass circumcision.The goal of this event is to circumcise 3,000 boys in a single day, breaking the previously held record and giving residents of Medan circumcision bragging rights over rival Indonesian cities for the next year.
