Germany's domestic intelligence chief warned Sunday of a radicalisation of right-wing groups amid a record influx of migrants, as xenophobic rallies and clashes shook several towns at the weekend.
President Joachim Gauck meanwhile warned of Germany's "finite capacity" to absorb refugees, cautioning against more "tensions between newcomers and established residents".
Domestic spy chief Hans-Georg Maassen said that "what we're seeing in connection with the refugee crisis is a mobilisation on the street of right-wing extremists, but also of some left-wing extremists" who oppose them.
