The mass transportation of refugees to Germany is set to stop after Austria said it would phase out emergency measures designed to help those stranded in Hungary.
Austria said the decision, a day after the measures were introduced, followed "intensive talks" with German Chancellor Angela Merkel and Hungarian Prime Minister Viktor Orban.
"We have always said this is an emergency situation in which we must act quickly and humanely," said Austrian Chancellor Werner Faymann.
"We have helped more than 12,000 people in an acute situation. Now we have to move step-by-step away from emergency measures towards normality, in conformity with the law and dignity."
More than 15,000 refugees arrived in Germany over the weekend, with moving footage emerging from Munich of families being reunited and refugees being cheered as they stepped off trains.
Germany said it was putting "no limit" on the number of refugees it would give sanctuary, while shocking images of three-year-old Aylan Kurdi washed up on a beach have contributed to a shift in policy in countries like the UK, where the Government is now preparing to accept 10,000 refugees.
The Pope has also intervened, calling on every parish in Europe to take in one refugee family.
But divisions remain across Europe in how to handle a crisis caused by Syrians fleeing their war-torn country.
EU foreign ministers failed to agree practical steps to solve the crisis during a meeting in Luxembourg on Saturday.
In Hungary, refugees are still being herded into camps - with some claiming they are being treated like "criminals".
Thousands of refugees have arrived in the country after travelling through the Balkans and Greece.
Hungary laid on 100 buses to transport some to Austria on Saturday night - but this now looks unlikely to continue.
Others have already taken matters into their own hands, making the 110-mile journey on foot.
Amnesty International researcher Barbora Cernusakova said: "While Europe rejoiced in happy images from Austria and Germany on Saturday, refugees crossing into Hungary right now see a very different picture: riot police and a cold hard ground to sleep on."
Hungary is constructing a fence to seal its southern frontier in order to keep out refugees - and they are not alone in providing a lukewarm welcome to the refugees.
Israeli Prime Minister Benjamin Netanyahu announced on Sunday that a fence would be constructed along his country's border with Jordan to prevent Syrian refugees arriving.
Amnesty International figures show the influx of refugees into Europe pales in comparison to the numbers taken by Lebanon (1.2 million), Jordan (650,000) and Turkey (1.9 million).
Division also remains on how to tackle the root cause of the mass migration from Syria, with reports the UK Government is seeking to persuade Labour MPs to back airstrikes in Syria.
France is also set to make a decision on airstrikes this week.
In the meantime, Syrians continue to flee in large numbers - some setting sail in dinghies hoping to reach Greek islands such as Lesbos.
More than 2,000 have died at sea so far this year.
