BRUSSELS, Aug. 5 (Xinhuanet) -- Belgian Holocaust denier Siegfried Verbeke has been arrested at Schiphol Airport in Amsterdam, the Netherlands, and might be extradited to Germany for trial, Belgian newspaper "De Standaard" reported on Friday.

    A German judge issued an international arrest warrant against Verbeke at the end of last year because he cast doubt on the internet over whether the Nazis actually killed six million Jews in World War Two.

    Germany asked Belgium to extradite Verbeke last year but a Belgian judge refused the request, the paper said.

    Verbeke has already been convicted in Belgium of denying the Holocaust. The appeals court in Antwerp sentenced him in April this year to a maximum one-year jail term and a 2,500-euro fine for anti-racism laws.

    The 63-year-old Verbeke has been the head of the Free Historical Research Center since 1983. The center has publishes books in which the Holocaust is denied or downplayed.

    Verbeke has used the principle of freedom of speech to defend himself in the past and is a renowned figure across Europe. He hadlinks with various ultra-right groups across the continent. Enditem
