The number of people reaching Lesbos, Samos and other Greeks islands in the eastern Aegean Sea is the highest since the European Union reached a 6 billion-euro agreement in 2016 to prevent migrants from leaving the coast of Turkey and heading to the EU. The surge started before Turkey’s military offensive against Kurdish fighters in Syria, but there are concerns that it could grow much bigger. Since the offensive began last week, Turkish President Recep Tayyip Erdogan has sought to quell European criticism by warning that he could “open the gates” and send more than 3 million Syrian refugees to Europe. Dinghies carrying migrants from Syria, Afghanistan, Iraq and elsewhere are reaching the islands despite enhanced coast guard patrolling in recent weeks supported by the Greek military. This is exacerbating problems at crowded refugee camps. A deadly fire at the Moria refugee camp on Lesbos on Sept. 29 triggered riots at the site, which is at 400% capacity. The Greek government promised to accelerate transfers to the mainland and expand the network of camps there. But those transfers have so far been outnumbered by new arrivals on the islands. Human rights group Amnesty International has described Moria as “overcrowded and unsafe” and urged other European Union countries to help Greece settle asylum-seekers. Authorities fear that if the arrival numbers remain high through October, a winter crisis will be difficult to avoid. Greece’s new conservative government says it also plans to detain migrants without the right to request asylum and wants to resume deportations back to Turkey under terms detailed in the 2016 EU-Turkey deal.
