A German teaching union has warned young girls to stay away from migrants, especially “attractive Muslim men,” or else they face being sexually assaulted.

According to the Mitteldeutsche Zeitung, an article in the Journal of the Philologists’ Association of Saxony-Anhalt said that an “immigrant invasion is spilling over in Germany” and advised teachers to warn their female students of the risk of being molested by migrants.

It added that girls should resist the temptation to indulge in a “superficial sexual adventure with the often attractive Muslim men.”

It claimed that while these migrants are often “young, strong, mostly Muslim,” they are also “often uneducated” and enter the country “under dubious pretences.”

Even innocent conversations with them, the article adds, could lead to sexual assault.

The article has caused outrage among German politicians, who have called it “base” and accused it of pandering to the “far-right fringe”.

Stephan Dorgerloh, education minister for Saxony-Anhalt, condemned the article, accusing the group of “amplifying rumours, spreading half-truths and exploiting its value as a union.”

Local Green Party chief Claudia Dalbert also weighed in, saying: “The content [of the article] is completely base, it serves prejudice and the far-right fringe.”

Germany is currently dealing with an unprecedented wave of immigration thanks to the ongoing migrant crisis in Europe. The country has been trying to deal with the numbers by spreading the migrants out in asylum centres in small towns across the country.

As numbers continue to rise, an increasing number of these centres are reporting incidents of violence as migrants from different parts of the world develop rivalries and clash with one another.

In one of the more severe incidents, around 50 people were involved in a violent brawl at a centre in the northern town of Itzehoe last weekend when Arabic-speaking migrants insulted Kurdish residents.

Security guards were forced to use pepper spray and deploy police dogs to break up the fight. Four asylum seekers were treated for head wounds while police said three migrants would be sent to “other centres around the country”.
