The clashes involved some 150 Afghan, Pakistani and Syrian migrants, reports said. Two houses were torched before police got involved and firefighters put out the blaze.
The violence comes after a fire broke out at a detention facility on the Aegean island of Lesbos, where over 70 people were injured and around 300 left without shelter.
Last month, Human Rights Watch issued a report saying that "inhumane" detention conditions in the Greek centers processing refugees create a volatile atmosphere that contributes to daily violence. However, local residents of Samos, once a popular vacation destination which has seen its tourist economy crumble under the weight of the unwanted arrivals, are up in arms over the use of their once-idyllic island as a dumping ground for unwanted asylum-seekers. Meanwhile, cash-strapped Athens is considering closing a deal with the EU to accommodate more migrants, now that EU-Turkish relations have soured.
