Members of a British tour group were shocked when staff at the Auschwitz Museum confiscated Israeli flags with hostage symbols because they were deemed “political.”

Personnel from the museum in Poland took the flags from members of the Bushey Synagogue in Hertfordshire.

The museum allows visitors to bring national flags to the museum, but the addition of the yellow ribbon symbol associated with the effort to return hostages from Gaza violated the museum’s rules concerning “political” messaging.
