At least 50 people have been arrested on the Greek island of Chios after violence erupted at a migrant camp.
According to local media, refugees set tents on fire before looting nearby shops, smashing cars and stealing fireworks to launch at local residents.
The riot was apparently triggered after those inside the Souda camp clashed with supporters of the far-right Golden Dawn Party.
Four people were reportedly taken to hospital following the unrest.
It is estimated more than 60,000 asylum-seekers remain stranded in Greek camps, often in overcrowded and poor conditions.
