BERLIN — Two German men were arrested Thursday on suspicion of spearheading a far-right group that posted pro-Nazi and anti-Semitic material online, prosecutors said.

A suspect accused of co-founding the "Goyim Party Germany" group in 2016 and identified only as Fadi J. in line with German privacy laws was arrested in the Dutch town of Heerlen, federal prosecutors said. The second suspect, Marcus B, who allegedly joined the group in 2018, was arrested in Berlin. Their apartments were searched, as were those of six other suspects.

German prosecutors said the group ran a website on which material denying the Holocaust and downplaying or approving of the crimes of the Nazi regime was posted. They said the site also featured "deeply disparaging anti-Semitic propaganda," including a call to kill Jews.

The two men were administrators for the group and played a leading role, according to prosecutors' statement. Federal prosecutors said they would seek Fadi J's extradition from the Netherlands to Germany.
