(ANSA) - STRASBOURG, OCTOBER 31 - Greece must urgently transfer asylum seekers from the Aegean islands and improve living conditions in reception facilities, said today the Council of Europe Commissioner for Human Rights, Dunja Mijatovic. "The situation of migrants, including asylum seekers, in the Greek Aegean islands has dramatically worsened over the past 12 months. Urgent measures are needed to address the desperate conditions in which thousands of human beings are living," said Mijatović, at the end of a five-day visit to Greece during which she visited reception facilities in Lesvos, Samos, and Corinth. "It is an explosive situation. There is a desperate lack of medical care and sanitation in the vastly overcrowded camps I have visited. People queue for hours to get food and to go to bathrooms, when these are available. On Samos, families are chipping away at rocks to make some space on steep hillsides to set up their makeshift shelters, often made from trees they cut themselves. This no longer has anything to do with the reception of asylum seekers. This has become a struggle for survival." (ANSA).
