ATHENS (Reuters) - Greece must speed up winter preparations at refugee camps on islands in the Aegean Sea where there has been a sharp rise in arrivals, the United Nations refugee agency said on Friday.

Nearly 5,000 refugees, mostly Syrian or Iraqi families, crossed from Turkey in September - a quarter of all arrivals this year, UNHCR data shows.
