[People queue for free food at a makeshift camp for migrants and refugees at the Greek-Macedonian border near the village of Idomeni]Urgent measures are need to address overcrowding and poor living conditions in refugee and migrant camps in Greece, Europe's top rights watchdog warned on Wednesday. The Council of Europe, which brings together 47 countries, said some facilities were "sub-standard" and able to provide no more than the most basic needs such as food, hygiene products and blankets. The Council described dire living conditions in several sites visited on a March 7-11 trip, just before the European Union and Turkey reached a deal that reduced arrivals but increased the number of people held in detention awaiting asylum decisions or deportation.
