School for Nazis: Parents' horror as children in German school begin greeting one another with 'Heil Hitler' and using Nazi slogans

An entire high school class in Germany is being investigated into after the teenage pupils allegedly started greeting each other with 'Heil Hitler' and communicating in Nazi slogans.

Parents and authorities are horrified after it emerged that the 29 boys and girls have been swapping assorted Nazi sayings and slogans throughout the school day on instant messaging-app WhatsApp.

Photos of 14 and 15-year-old students at a school near Leipzig in east Germany show them giving Nazi salutes and wearing Hitler moustaches.

Horrific: A photograph of one of the male students in class 9A at the Landsberg School near Leipzig, east Germany, shows him raising his right arm in a Heil Hitler salute

Students in class 9A at the Landsberg Gymnasiums near Leipzig regularly made anti-Jewish slurs on the messaging app, while praising Hitler as a 'great man,' local media reports.

Photos appeared in Germany's biggest newspaper BILD on Tuesday showing individuals giving the Hitler salute: one boy who was wearing a stuck-on Hitler moustache had his face blacked out. 

One of the messages from a student made a Holocaust joke that read: 'Why did Hitler kill himself? The Jews sent him the gas bill.'

Parents and teachers worry they are losing the battle with neo-Nazis across the country who are increasing the pressure on schoolchildren to join their ranks. 

Fear: Parents are in shock after it emerged that all 29 students in the class, boys and girls ages 14 and 15, appear to have been engaging in the WhatsApp

A spokesman the state educational affairs minister in Saxony-Anhalt said: 'I am shocked. If this is true there can only be one way forward here: zero tolerance!'

The WhatsApp exchanges have been handed over to police and prosecutors.

Any public display of Nazi symbols, salutes or phrases is a strictly forbidden act in modern-day Germany which can carry a first offence penalty of up to six months in jail.

All the class students, like all children in Germany, have visited a Nazi concentration camp and regularly learn about the excesses of the Third Reich in classes. 

In shock: The school, Landsberg Gymnasiums near Leipzig, where the teenagers all study

Police said two teenagers are under investigation while a more extensive probe gets underway next week when the school reopens after the half-term break.

Media reports said a psychologist has been arranged to meet with the children, teachers and their parents next week to try to get to the bottom of the fascination with Nazism.

Neo-Nazi groups significantly stepped up their recruitment of children in recent years.

The state of Mecklenburg-Vorpommern near Berlin has started carrying out background checks on would-be kindergarten employees after it was discovered several had been infiltrated by far-right females.
