EU countries are making yet another attempt to get past deep-seated divisions over how to deal with the thousands of asylum-seekers arriving every day in Europe.

Interior ministers from the bloc’s 28 members meet in Brussels Monday for talks aimed at approving a set of “emergency” measures on migration, including plans to relocate refugees across the continent. European Council President Donald Tusk underlined the importance of the meeting with an ultimatum, saying Friday that if countries did not show a “concrete sign of solidarity” he would call a special summit of EU heads of state and government to address the issue.

European Commission President Jean-Claude Juncker has also pushed for more decisive action from EU member countries, saying in his September 9 State of the Union address that “immediate action” is needed at a “defining moment” for Europe. His top priority: a new proposal for the emergency relocation of 120,000 asylum-seekers.
