Germany needs to ban alcohol if it wants to prevent further sexual violence and to help North African migrants integrate into society, a Muslim pressure group has claimed.

Commenting on the Cologne sex-attack controversy, MuslimStern, which has 20,000 followers on Facebook, said its mission was to 'highlight the way the media was using the incidents to promote racism against minorities'.

The group complained that the female victims had brought the unwanted attention to themselves by dressing in a manner that North African men were not accustomed to.

Large groups of Muslim men who congregated around the cathedral in Cologne on New Year's Eve are believed to be responsible for more than 520 sexual assaults and at least three rapes on women in the city

The MuslimStern Facebook page has called on German authorities to ban alcohol claiming that Cologne women were responsible for their own attacks by comparing them to a naked antelope thrown in front of a lion

The group claimed: 'The government should ban the consumption of alcohol because it leads to traffic accidents, violence and rapes, and is extremely damaging to health. But for capitalist societies, this is too much to expect. So long as alcohol is not prohibited there will be no discernible decline in these cases'

The group claimed: 'You cannot expect to chuck a naked antelope in front of a lion and not expect it to react. It is mind boggling that with so much time spent teaching children about sex at school, they completely forget to pass on this basic biological fact.'

As a consequence of the attacks, they urged the German government to introduce a ban across the country on the consumption of alcohol.

The group also blamed women for getting attacked by inciting the young men.

In one section of the Facebook post, which has since been deleted, the group claims: 'Some women should think about whether it is wise to lightly dressed and drunk, to go between hordes of drunken men.

'In general, the woman wearing due to their nature have a responsibility when it goes out of the house.

'You can not throw a naked antelope from a lion and expect that at the lion stirs nothing.

'It is amazing that is taught in biology class so much about the mating and sexual behavior of living things, but these rules are completely ignored in everyday life.

'And because many non-Muslims constantly emphasise that we live in a Christian country, we call on you, in this country that women should dress Christian.

'Mary, Mother of Jesus, lived out as a Christian woman has to dress. So it would be highly recommended for some women to take Mary as a role model and not Lady Gaga.'

More than 520 women have reported assaults from New Year's Eve with at least three rapes which have been blamed on Muslim migrants who congregated around Cologne's cathedral during the night.

Cologne's Muslim preacher Imam Sami Abu-Yusuf, who blamed women wearing perfume for the fact they were assaulted over the New Year, went on to justify it by saying that alcohol had taken away the restrictions of 'men from North Africa'.

He also added that the sex attackers were 'from North Africa', unlike Salafists like himself who are mostly from India and the Middle East.

Mr Yusuf had earlier told Russian TV women only had themselves to blame for being assaulted because of the way they dressed. When asked why the attacks had happened he told REN TV: 'One of the reasons is the way the women were dressed. If they just wear light clothing and put on perfume, then things like this will happen.'

After the comments local Green MP Volker Beck complained to police about the comments saying it was incitement to carry out crime.

As the controversy raged over the remarks, a reporter from the Cologne Express asked him to qualify his statements, and reported that he laughed when asked if he really believed that women were responsible for the attacks they suffered.

He told the Express: 'My reply was taken out of context. What I said was that we have a real problem with men from North Africa living in Cologne. These young men take tablets and drugs, and over New Year they took alcohol which took away all the barriers.'

The number of sexual assaults has prompted numerous demonstrations in Germany and caused significant political problems for chancellor Angela Merkel who is seeking to resolve the issue of uncontrolled migration

Cologne police were heavily criticised for their failure to protect women from the men who had gathered

Asked if that was the reason he was saying the women were attacked, he said: 'No, that is of course forbidden and not only for Muslims. But there were women with very open clothing and they were wearing perfume, and at the same time while walking through the drunken masses, of course for these North African men, that was an excuse to grope them. That doesn't mean to say that I believe women cannot be dressed like this. Everyone has to accept that.'

However as the controversy grows, German security experts have admitted that they had the mosque where he preaches under surveillance for more than a decade, including a raid in 2004 over suspicions that it was at the heart of a secret network of Arabic mujahedeen.

However they failed to come up with any concrete evidence of terrorist attacks that were planned. It has also been confirmed that he is regarded as Salafist extremist orientated on Wahhabism, which is the stricter Saudi Arabian form of Islam.

German FDP-Politician Tobias said: 'His statements are typical thinking for a Salafist. Not just he but other Salafists and Salafists on online platforms have justified the rape of women in the same way.'
