Greece will shut down its largest three migrant camps on islands facing Turkey, and replace them with new facilities, officials said Wednesday.

The Greek government said it would close existing, badly overcrowded camps on the islands of Lesbos, Chios and Samos, and replace them with new closed facilities with a capacity of at least 5,000 people each.
