Clashes between Eritrean government supporters and opponents at a cultural festival in Germany has left dozens injured, including at least 26 police officers.
Violence flared shortly before the event was due to begin in Stuttgart on Saturday afternoon.

Six of the injured officers needed hospital treatment.
The confrontation was the latest unrest to mar Eritrean cultural events in Germany and elsewhere.
In July, a clash at an Eritrean festival in the western German city of Giessen left 22 police officers injured.
Earlier this month, there was rioting in Tel Aviv after demonstrators were stopped from reaching the Eritrean embassy.
The event in Stuttgart was organised by several groups considered close to the government of Eritrean President Isaias Afwerki.
Tens of thousands of people have fled Eritrea for Europe, with many claiming they were mistreated by the repressive regime.
