Turkey president Recep Tayyip Erdogan has sharply criticised European Union countries' response to the humanitarian crisis engulfing the continent.
He made the comments as the first boats carrying migrants deported from Greece arrived in Turkey under a controversial new plan.
With a police helicopter hovering overhead and flanked by two coastguard vessels, the first passenger boats have arrived from Lesbos and Chios in the Turkish town of Dikili.
Most of the 202 people on board were Pakistani, but many also came from Afghanistan, Iran, Sri Lanka and Morocco.
The group was transferred under a new deal between the European Union and Turkey aimed at stemming the flow of migrants and refugees into Europe.
EU authorities say none of those deported so far had requested asylum in Greece and all had left voluntarily.
They were taken by bus to a registration centre near the Bulgarian border.
But as the first groups were transferred back to Turkey, still more people arrived at the Greek islands.
Greece's coastguard rescued more than 170 people off the coast of Lesbos, many of them unaware they could be sent back.
Firaz Kassem, who originally fled Syria, says he has no intention of returning to Turkey.
"We're just going to try our chance, just follow our destiny. We don't know where we're going to ... We are dead anyway. We just want to get here and we get rid of Turkey, because we don't want to go to Turkey anymore. We have suffered there a lot. We don't want to go there anymore. Anywhere is better than Turkey. We're done with it."
Meanwhile, Turkish president Recep Tayyip Erdogan has criticised the EU, saying it is his country that has embraced three million Syrians despite being financially worse off than others.
(Translated) "They put (up) barbed wires for not letting these people in their countries. It is known (about) how many people died in the Aegean Sea, but the number of people we rescued in the Aegean Sea is 100,000. We picked them up with our coastguard boats, and we continue to do so."
Under the deal, for each Syrian migrant returned to Turkey, the European Union will take another Syrian who has made a legitimate claim.
The first 32 Syrian refugees have now arrived in Hanover, Germany, on two flights from Istanbul.
A spokeswoman for the Friedland Refugee Admission Centre, Hannah Buschman, says they seem overwhelmingly happy to be in Germany.
(Translated)"In the first week, they will have to go through some administration issues, like health tests. And then in the second week, they will attend a course that includes language classes, some German history, political and cultural information and how to use public transport. And then on the next Monday, they will be distributed across Lower Saxony."
But for those in Turkey, questions remain about whether the country has sufficient safeguards in place to defend refugees' rights.
Gauri Van Gulik is a spokeswoman for Amnesty International.
"All of this is based on the assumption that Turkey is a safe country for refugees, and we've documented very clearly that it is not right now. We've documented returns of Syrians from Turkey to Syria, for example. And so all of that means that this deal cannot be implemented right now safely and legally in the way that the EU is so doggedly determined to do."
The humanitarian crisis has affected vast areas of Europe, including the Greek village of Idomeni.
It is now home to thousands of migrants and refugees, many getting more and more upset.
Protesters at Idomeni have blocked the Greece-Macedonia highway for a third time, pleading with authorities to open the borders.
