The so-called “Nazi grandma” has been convicted — yet again — in Germany of denying the Holocaust and sentenced to six months in the slammer, according to reports.

Ursula Haverbeck, 88, was sentenced by a Berlin court Monday for claiming during a public event in January 2016 that gas chambers in the infamous Auschwitz concentration camp “were not real.”

She also disputed the fact that 1.1 million people were killed at the camp in Nazi-occupied Poland, Agence France-Presse reported.

The court in Berlin found Haverbeck guilty after examining a short video of her speech in which she claimed that she was citing a book, not expressing her own views.

Denying the Holocaust, in which six million Jews were slaughtered, is a crime in Germany because it constitutes incitement of racial hatred. The crime is punishable by up to five years in prison.

Haverbeck is a notorious extremist who was once chairwoman of a far-right training center that was shuttered in 2008 for spreading Nazi propaganda.

She had also claimed on television that “the Holocaust is the biggest and most sustainable lie in history.”

Haverbeck has faced similar legal cases across Germany.

In November 2016, she was convicted in Verden on the basis of articles she had published in the local newspaper Stimme des Reiches, or “Voice of the Reich,” the Israeli Haaretz newspaper reported.

The previous month, a court in Bad Oeynhausen sentenced her to 11 months for incitement to hate. And in September 2016, a court in Detmold sentenced her to eight months in jail.

In 2015, a Hamburg court sentenced her to 10 months in jail.

Despite all the convictions, which she has appealed, Haverbeck has not served any jail time. She also filed an immediate appeal against Monday’s ruling.
