A rudimentary processing centre set up in a stadium on Kos was largely empty Thursday morning after police issued temporary travel papers to at least 1,000 men, women and children.
But large numbers of refugees remain camped outside the stadium waiting to register. The influx has overwhelmed local authorities.
More than 200 people, mainly Syrian Kurds from the war-devastated town of Kobani, arrived early Thursday, in at least six rubber boats. Another group of refugees was picked up at sea by a coast guard launch.
