Unidentified assailants have thrown petrol bombs, fireworks and stones at migrants' tents in Souda, on the Greek island of Chios, forcing about 150 people to flee.
It was the second night of violence in and around Souda camp. About 4,000 migrants and refugees are on Chios.
Several tents, including one housing 50 people, were damaged in the violence, the UN refugee agency (UNHCR) says.
On Wednesday four migrants were arrested after fireworks were thrown.
Greek police said the four were three Algerian teenagers and an Iranian man. The fireworks were allegedly stolen from a shop.
