Polish authorities are searching for three teenage girls who posed for a picture at the entrance of the Auschwitz-Birkenau death camp while doing a Nazi salute, according to the British Daily Mail.
The girls shared the picture on Instagram this Tuesday, but deleted it shortly after.
A group called Center for Monitoring Racist and Xenophobic Behavior, which monitors online anti-Semitism, shared the picture on Facebook and criticized the girls’ behavior.
The center said that “this kind of behavior proves that there is a dire need for educational activities that deal with the horrors of totalitarian regimes and of the Holocaust, in light of the rising anti-Semitism in Poland,” adding that “youth are absorbing hate messages unconsciously.”
The center was able to save a copy of the photo before it was deleted, and authorities are trying to identify the girls in order to report them to their school.
