Andreas Geisel, Berlin's interior minister, said on Wednesday that hatred towards Germans was on the rise in the capital, but cautioned that it was still far from the norm.
"I have heard that [reports of hatred against Germans]. It is not the norm but it is becoming more common - to keep quiet about it would be wrong," Geisel told daily newspaper Tagesspiegel.
"What can we do about it? It is clear that we need to intensify our efforts to integrate people. That includes German and ethics courses for refugees, optimally for all of them," the Social Democrat added.
The interior minister was responding to a long report published by Tagesspiegel on Tuesday which asked whether Berlin was becoming "a place of fear."
