Israel Police arrested 13 suspects in a fight Sunday night in southern Tel Aviv.
The fight between dozens of infiltrators broke out during a celebration of Eritrea's Independence Day, and against the backdrop of disagreements between foreign residents - opponents and supporters of the Eritrean government.
Some of those involved threw stones.
Several people were lightly injured, including a policeman.
Police broke up the fight, arresting 13 people, eight of whom will be brought to court on Monday for an extension of their arrest.
