Migrants waiting to register before being let into a football stadium on the Greek island of Kos yesterday. Overwhelmed police yesterday beat some with truncheons and sprayed them with fire extinguishers. Kos' mayor warned that the refugee crisis on the island could end in "bloodshed". The migrants, mostly Afghans and Syrians, were being moved to the stadium after camping by roads and on beaches for weeks. The four policemen were said to be trying to stop a stampede. On Monday, a Kos policeman was suspended after being filmed slapping migrants.
