(JNS.org) Hundreds of copies of the Diary of Anne Frank, along with other books on the Holocaust, were found vandalized in libraries across Japan. According to reports, 31 municipal libraries across Japan had found at least 265 copies of the diary with pages torn or ripped out. Yoshihide Suga, a top government spokesman, expressed disappointment and promised an investigation. “It is extremely regrettable and shameful,” he told Japanese reporters, according to the New York Times.

The Simon Wiesenthal Center expressed its “shock and deep concern” over the vandalism, and expressed hope that Japanese authorities will investigate and prosecute whoever is behind this.
