Dozens of boat people from the Middle East are flowing into the Greek holiday island of Kos from nearby Turkey, joining thousands of refugees camped under wretched conditions.

Overwhelmed and unprepared for the unprecedented influx, authorities on the eastern Aegean Sea island have been heavily criticized for their treatment of the migrants — mostly refugees from Syria.

At least two rubber boats made landfall Wednesday, while an Italian coast guard boat participating in a European border watch mission brought in about 50 people rescued at sea.

Authorities on Kos have started evicting refugees sleeping rough in parks and streets, locking them in an old football stadium that is the island's main registration center.

The international Doctors Without Borders charity heavily criticized Greek authorities, voicing deep concern at the situation.
