BRUSSELS -- European Union leaders Friday drew up new plans to screen migrants in North Africa for eligibility to enter Europe, saying they set aside major differences over stemming the flow of people seeking sanctuary or better lives. But the show of unity did little to hide the fact the hardest work still lies ahead.

Even as they met in Brussels for a second day, Libya's coast guard said about 100 people were missing and feared dead after their boat capsized in the Mediterranean.

The leaders agreed on a "new approach" to manage those rescued at sea, just as bickering over who should take responsibility for them undermines unity and threatens cross-border business and travel in Europe.

Italy, Greece and Spain bear responsibility for accepting most of the migrants and have felt abandoned by their EU partners. Italy, with a new anti-European government, has refused to take charge of people rescued at sea in recent weeks, sparking a diplomatic row with France and Malta. In Germany, Chancellor Angela Merkel's coalition partner is demanding she take a tougher line on migrants, undermining her leadership.

The new plan is to receive people from rescue ships in EU nations agreeing to share responsibility for handing migration with the EU's main point-of-entry countries like Spain, Italy and Greece. But they also will receive them in centers in North Africa and possibly the Balkans.

"A complete approach was adopted," French President Emmanuel Macron told reporters after a night of haggling and delays to address demands from Italy its views be incorporated in the final summit statement.

"We are protecting better. We are cooperating more. And we are reaffirming our principles. All hastily made solutions, be they solely national ones or a betrayal of our values that consists in pushing people off to third countries, were clearly set aside," Macron said.

Even new Italian Prime Minister Giuseppe Conte, whose populist government has rocked the EU's political landscape, said: "On the whole, we can say we are satisfied."

"Italy is no longer alone, as we requested," he said.

That said, the Czech Republic and Austria have no intention of basing migrant centers on their territory.

"Why should there be centers? Center should be outside of Europe. Ellis Island, yes? And the Australian model, very simple. We have to execute this," Czech Prime Minister Andrej Babis said.

The "disembarkation platforms" are a logical extension of the EU's migrant deal with Turkey. The government in Ankara was paid more than 3 billion euros in refugee aid to stop people leaving for the Greek islands. The bottom line is numbers have dropped by about 96 percent, compared with 2015 when well over 1 million people entered Europe, most of them fleeing conflict in Syria and Iraq.

Algeria, Egypt, Libya, Morocco, Niger and Tunisia are touted as possible locations, even though details of the plans are sketchy. Morocco already has refused and none of those listed has volunteered to take part. The EU's executive Commission now must draft something more concrete in coordination with the U.N.'s refugee agency and the International Organization for Migration, which would prefer to operate in European migration centers only.

Libya is a major transit point to Europe for those fleeing poverty and violence in Africa and the Middle East. Traffickers have exploited Libya's chaos following the 2011 uprising that toppled and later killed dictator Moammar Gadhafi.

How much the plans will cost remains a mystery, but it won't be cheap.

The UNHCR cautiously welcomed the plan but warned it must be fleshed out and African involvement via the African Union regional bloc is "indispensable."

IOM spokesman Leonard Doyle said his agency was "very pleased at the solidarity and consensus" emerging in Brussels, in particular with front-line states such as Italy.

Doyle said he believed most of the "disembarkation centers" would be in Europe, although he said it was up to the EU to determine which countries would host them.

UNHCR spokesman Charlie Yaxley said the refugee agency is "still awaiting the legal analysis" of the new plan but would certainly welcome greater EU collaboration on handling asylum claims.

He noted for the fifth year in a row, the "grim milestone" of 1,000 migrant deaths in the Mediterranean has been passed already, just halfway through 2018.

But even as migrant arrival numbers drop, the situation has been heating up.

Anti-migrant parties have been fomenting public fear of foreigners, winning votes in Italy, Austria, Slovenia and elsewhere.

The UNHCR said about 40,000 migrants have arrived in Europe by sea this year, almost six times fewer than over the same period in 2016. Many who entered in 2015 and 2016 were fleeing conflict and thus eligible for asylum. Most arriving now seek better lives and probably would not qualify, which means more people face the prospect of being sent back.

"It is far too early to talk about a success," EU Council President Donald Tusk told reporters after a compromise was found. "This is in fact the easiest part of the task, compared to what awaits us on the ground, when we start implementing it."
