Answering a question on Friday at a town hall event in Berlin, Zuckerberg said: "Hate speech has no place on Facebook" and that he had being instituting better controls on monitoring and removing it.
German officials have expressed concerns about far-right and other groups using Facebook to spread their messages. Zuckerberg talked personally with Chancellor Angela Merkel about the issue last year.
Zuckerberg says "until recently in Germany I don't think we were doing a good enough job, and I think we will keep needing to do a ... Better job."
He says Facebook in Germany now treats migrants as a "protected class" of people.
