The Jewish information centre CIDI is demanding a list of Jewish Dutch people be taken off an extreme right-wing website immediately.

The website Altrechts.com includes a list of ‘Jews and part-Jews’ and a page which ‘attempts to quantify the influence of Jews in the Netherlands and Belgium.

CIDI says the website is extremely worrying. ‘We don’t have to explain what violent anti-semites can dowith such a list,’ the organisation says on its website.

It is unclear who is behind the website which is registered via a Panama server with identity protection. The website, which was offline on Friday afternoon because of a system overload, describes Jews as ‘alien organisms’.

Another website section lists ‘enemies of the people’ which it describes as ‘Marxists, feminists and homosexuals’. The list also claims to include the names of people who signed a petition calling for the abolition of Zwarte Piet.

Internet discrimination hotline MIND told the NRC it has received several complaints about the website and that the public prosecution department is also investigating.
