LESBOS, Greece (AP) — At the heart of Moria, an overcrowded refugee camp on the Greek island of Lesbos, is a dark rectangular building ringed with police guards and coils of razor wire. Taking photographs of it is prohibited. It's here that thousands of migrants are interviewed by asylum officers — and ultimately informed whether they will ever be allowed to leave the island. Holding up a tattered asylum card that reads "Forbidden to travel outside Lesbos," 40-year-old Syrian Ziad Rashid said he was supposed to be deported back to Turkey after he unsuccessfully appealed his failed application. But Turkey's effective refusal to re-admit migrants means there's nowhere he can go.
