More than 3,000 people fled a fire in a refugee camp on the Greek island of Lesbos, Greek media reported.
The blaze broke out during clashes between different nationalities of refugees living in the Moria refugee camp, the online newspaper I Efimerida reported. There were no reports of injuries.
Rescue personnel transported children to another detention centre, according to the Lesvos News. The action prompted refugees to flee the camp and make their way to the island capital, Mytilini. The migrants are demanding to be allowed to travel to Athens.
Video posted on social media purporting to be of the incident showed large flames as tents and other housing apparently burned.
Moria was built to house 1,500 people but is vastly overcrowded.
Lesbos is the third largest Greek island after Crete and Euboea. At the height of the migrant crisis last year more than 7,000 people a day were landing on its shores.
Currently approximately 5,500 refugees and other migrants remain on the island.
