Migrants arrive on the shore of Kos island on a small dinghy on Wednesday. Authorities on the island of Kos have been so overwhelmed that the government sent a ferry to serve as a temporary centre to issue travel documents to Syrian refugees — among some 7,000 migrants stranded on the island of about 30,000 people.

A Syrian migrant arrives after crossing from Turkey by a rubber boat, seen in the background, in the southeastern island of Kos, Greece, Monday, Aug. 17, 2015. Greek authorities said Sunday they have started resettling migrants living in tents in a park in the capital Athens   but many were wary and had moved out ahead of the operation. More than 130,000 migrants have reached Greece so far in 2015, straining the country's resources
