European Union leaders gather in Brussels on Sunday in an attempt to bridge their deep divisions over migration, an issue that has been splitting them for years and now poses a fresh threat to German Chancellor Angela Merkel.
Though arrivals across the Mediterranean are only a fraction of what they were in 2015, when more than a million people reached Europe, a recent opinion poll showed migration was the top concern for the EU's 500 million citizens.
Under heavy pressure from voters at home, EU leaders have been fighting bitter battles over how to share out asylum seekers in the bloc.
Unable to agree, they have become more restrictive on asylum and tightened their external borders to let fewer people in. They have given money and aid to countries in Northern Africa and the Middle East to keep people from heading for Europe.
Only 41,000 refugees and migrants have made it to the EU across the sea so far this year, UN figures show.
But the issue has in the meantime won and lost elections for politicians across the bloc from Italy to Hungary, with voters favouring those advocating a tougher stance on migration.
On Saturday, French President Emmanuel Macron said France favoured financial sanctions for EU countries that refuse migrants with proven asylum status.
Merkel is under pressure because her longtime conservative allies, Bavaria's Christian Social Union (CSU), have threatened to start turning away at the German border all asylum seekers already registered elsewhere in the EU unless the bloc reaches an agreement on distributing them more evenly.
They mostly live in countries like Greece and Italy - both long overwhelmed with arrivals - or wealthy states like Germany or Sweden, where they choose to try to start a new life.
The ex-communist states in the EU's east led by Hungary and Poland have refused to host any of the new arrivals, citing security risks after a raft of Islamist attacks in Europe.
The bloc has been unable to break the deadlock, the bad blood spilling over to other areas of their cooperation, including crucial talks on the bloc's next seven-year budget from 2021.
With Germany being the main contributor to the bloc's joint coffers, the southern gateway countries were promised more money to handle migration, while the reluctant easterners face cuts in development aid.
Merkel is now pushing other EU states, including Italy, to do more on migration so that fewer people get to Germany and she can convince the CSU not to go ahead with their plan.
She opposes the idea by the CSU, which will face the anti-immigration AfD party in Bavarian elections in October, because it would mean rigid border controls inside what is normally the EU's coveted control-free travel zone.
To placate the CSU, Merkel must get something from Sunday, arranged hastily among more than a dozen EU capitals, and also from the full summit of the bloc's 28 leaders on June 28-29.
All EU leaders agree they must further curb immigration by working with third countries, though that often proves slow.
Berlin's other idea is to send back those asylum seekers who make it to countries like Germany to the states of their first arrival, like Italy.
But Rome has already rejected measures that could see it handle even more people and the Sunday talks are all but certain to see the two countries clash.
In the mid-term, the EU is only going to become tougher on migration, something rights groups denounce as turning it into a "fortress" beyond reach for those less privileged.
The U.N. refugee agency chief Filippo Grandi reminded the bloc that the height of their migration crisis was back in 2015.
"Despite today's dramatically lower arrival rates, the shockwaves of that event still reverberate - at the political level, and in the tendency towards restrictive, unilateral approaches that some European countries have pursued," he said."EU policies on asylum can and should set an example on how to manage refugee situations with compassion and solidarity," he added, urging the bloc to overcome its divisions to help those in need rather than focus on just winning the next election.
