A former German government official Uwe-Karsten Heye says black visitors will risk their lives if they venture into areas of the country where racist attacks are on the rise. These flowers mark the scene of a brutal attack on a 37-year-old Ethiopian man.

Around 100 people have been killed as a result of far-right violence since German reunification in 1990. The majority of the attacks have occurred in the former communist states.
