"Fair distribution of at least 100,000 refugees among EU states is what we need to do," Tusk, who chairs summits of EU leaders, told a joint news conference in Brussels with Hungarian Prime Minister Viktor Orban.
EU countries have so far committed to share about 32,000 asylum seekers from Italy and Greece, a number short of a European Commission proposal of 40,000. A new proposal from the EU executive is expected next week, Reuters reported.
Tusk called for refugees' reception centres to be built close to war zones and "outside Europe, where refugee camps already exist" and also said EU leaders should be ready at a summit next month to commit much more money to the migration crisis.
