Europe's biggest refugee camp overflows as migration surges again

Greece's 3rd-largest island, Lesbos, is overflowing with refugees as the "rate of arrivals hit the highest level since a European Union crackdown on migration three years ago," AP reports.

Why it matters: "Lesbos and other Greek islands facing Turkey’s mainland were used as a physical barrier to Europe’s mainland," per AP. The Moira refugee camp on Lesbos houses 12,000 people in a space meant for 3,000. Nearly 7,000 are stuck on the hillside outside the refugee camp as winter approaches — a dangerous place to be, as Lesbos is a "magnet for migrant traffickers," per AP.
