According to the UN Refugee Agency, there are approximately 19,600 migrants and refugees on the Aegean islands as of 8 November. A series of large blazes destroyed Greece's largest migrant camp, Moria on the island of Lesbos, back in September. The Greek authorities said that the fires were deliberately started by the camp's residents. Officials on Samos reported a similar fire at a migrant camp on 2 November, the second blaze to hit such a facility over the last ten days. The cause of this fire has not yet been determined, and the number of migrant tents destroyed by the blaze is not yet known.
