Several people have been targeted by xenophobic attacks across Germany in the past 48 hours, police confirmed on Tuesday.
Two Israeli students, an Indian man, a man of African descent and a teenager with German citizenship were among the people that were targets of attacks in Cologne, Dresden and Duisburg, police said.
The attacks may be retaliatory crimes after hundreds of assaults against women on New Year's Eve in several German cities were linked to foreigners.
In Cologne, 653 complaints have been filed with police, prompting politicians to call for increased security, the expulsion of criminal asylum seekers and the reduction of migrant flows going forward.
Two Israelis aged 25 and 26 were verbally and physically attacked by six men dressed in black at the sidelines of an anti-immigrant rally in Dresden late on Monday, police said.
At the sidelines of a similar demonstration in Duisburg, two suspects attacked and injured a dark-skinned 18-year-old German citizen. Both suspects had been attending the rally and were later detained, police said.
Meanwhile, an Indian man was attacked in Cologne by a large group of men and sustained injuries to the face, senior prosecutor Ulf Willuhn said.
