The refugee crisis on three Greek islands near Turkey is "total chaos", the UN refugee agency UNHCR says. Accommodation, water and sanitation are all inadequate for the many asylum seekers on Kos, Chios and Lesbos, the UNHCR says, calling it "shameful". Greece has urged the EU to help, faced with the record influx. The UNHCR says nearly all are refugees from the wars in Syria, Iraq and Afghanistan. Austria's main migrant camp - Traiskirchen - is also overcrowded.

The UNHCR's European Director, Vincent Cochetel, said facilities for the refugees on the Greek islands were "totally inadequate", after a 750% increase in migrants arriving this year, compared with the same period last year. He said 124,000 had arrived in Greece so far this year, including 50,000 in July alone. Greece's EU partners must do more to ease the burden, he said, but Greece must "lead and co-ordinate". "On most of the islands there is no reception capacity, people are not sleeping under any form of roof. So it's total chaos on the islands.

"After a couple of days they are transferred to Athens, there is nothing waiting for them in Athens," he complained.
