The huge global scale of female genital mutilation has been revealed in disturbing new statistics, which show at least 200 million girls and women alive today have undergone ritual cutting, half of them living in just three countries.

The latest worldwide figures, compiled by Unicef, include nearly 70 million more girls and women than estimated in 2014 because of a raft of new data collected in Indonesia, one of the countries where FGM is most prevalent despite the practice being banned since 2006.

In the analysis of 30 countries, published to mark the International Day of Zero Tolerance for FGM, statistics showed women in Indonesia, Egypt and Ethiopia account for half of all FGM victims worldwide. Somalia has the highest prevalence of women and girls who have been cut – 98% of the female population between the ages of 15 and 49.
