“Now is the time to see if the EU is the EU of solidarity or an EU that has everyone trying to protect their borders,” he said after a meeting with ministers dealing with the influx.
The United Nations refugee agency called on Greece to take control of the “total chaos” on Mediterranean islands, where thousands of migrants have landed. About 124,000 have arrived this year by sea, many via Turkey, according to Vincent Cochetel, UNHCR director for Europe.
“The level of suffering we have seen on the islands is unbearable. People arrive thinking they are in the European Union. What we have seen was not anything acceptable in terms of standards of treatment,” Cochetel said after visiting the Greek islands of Lesbos, Kos and Chios.
Greek authorities must “lead and coordinate the response”, said Cochetel, a 30-year UNHCR veteran. “I have never seen a situation like that. This is the European Union and this is totally shameful.”
Greece, along with Italy, has been on the front line of a huge wave of people seeking safety and a better future in Europe.
But the Greek economy is falling into recession again after having only just recovered from six years of recession brought on by its debt crisis. As a result, the government says it cannot handle the pressure from thousands of penniless refugees.
“The immigrant flow to Greece is beyond of what our state infrastructure can handle,” Tsipras said. “We have significant problems to face it and that’s why we have asked help from EU.”
While recognising that the migrant crisis is “not necessarily the top priority for everyone in the government”, Cochetel said Greece must still deploy an emergency response plan.
“We’ve told the Greek authorities that if it was a natural disaster, there would be mobilisation of other assets including from the ministry of defence,” he said.
“So let’s call it a civil protection emergency, let’s mobilise those assets, because they have plans for that sort of natural disaster.”
He added: “It’s easy, there are plenty of empty army barracks in Greece, there is plenty of uncultivated land that could be rented and sites could be developed.”
The European Union has sought to share the burden of the refugees across its member countries, but the response has been mixed. EU leaders have pledged to relocate 16,000 migrants over two years, which Cochetel called “far too little and too late”.
Britain has said it will not participate. It is currently struggling with its own crisis as thousands of migrants seek to enter via the Channel Tunnel.
Hungary is also preparing to build a fence along its border, where migrants from the east seek to enter.
The UNHCR called on Greece on Friday to take control of the “total chaos” on its islands.
European Union member states must also do more to share the burden of Greece, where 50,000 people arrived in July alone, said Cochetel after visiting the Greek islands of Lesbos, Kos and Chios.
“In terms of water, in terms of sanitation, in terms of food assistance, it’s totally inadequate. On most of the islands, there is no reception capacity, people are not sleeping under any form of roof,” he told a news briefing.
“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.”
Greek authorities must “lead and coordinate the response”, said Cochetel, a 30-year veteran of the UN High Commissioner for Refugees who said he had “never seen a situation like that”.
“We are concerned with the situation where no one is really assuming leadership in the response, which makes it very difficult for humanitarian operators to participate in the efforts,” he said.
Cochetel voiced concern that the situation not degenerate in Greece or be “exploited” for political ends.
“The top priority is not to let other Calais develop in other places of Europe,” he added. Many migrants head for the French port, and at least 10 have died trying to enter Britain through the Channel Tunnel.
