Greece's economy shrinks further.
Police in northern Greece move more than 400 Syrians and Iraqis by bus from a makeshift camp near the Macedonian border to a shelter near the northern city of Thessaloniki. More than 50,000 migrants remain stranded in Greece following European border closures, and the European Union's agreement with Turkey.
Balkan and European leaders agree to work together implementing a 17-point action plan that includes United Nations-aided accommodation for 100,000 places in reception centers along the route from Greece towards Germany, half in Greece and half in the countries to the north. Some of the other measures: within a week, deploy 400 police officers to Slovenia; step up efforts to return migrants not needing international protection; and, reinforce support of the bloc’s border agency, Frontex', role in securing external borders between Bulgaria, Turkey, Greece, Macedonia, and Albania.
A fourth successive attempt by major Greek political parties to form a coalition government ends in failure. Another attempt is scheduled for May 15; if a coalition cannot be agreed, emergency elections must be held in June.
