A German spy chief warns of radicalisation as this year alone has seen 22 arson attacks against refugee shelters.
Germany's domestic intelligence chief warned on Sunday of a radicalisation of right-wing groups amid a record influx of migrants, including refugees, as xenophobic rallies and clashes shook several towns at the weekend.
"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, said Hans-Georg Maassen on Deutschlandfunk public radio.
Maassen spoke as Germany expects up to one million migrants this year, and after protests against refugee homes and clashes with police again rocked several towns at the weekend, mostly in the former communist East Germany.
