BRUSSELS (Reuters) - Nearly half a million irregular migrants arrived in Greece in the last three months of 2015, most of whom then moved north through the Balkans, data from EU border agency Frontex showed on Thursday.

Frontex, which collates data on the number of irregular border crossings, recorded 484,000 such incidents on the Eastern Mediterranean route from Turkey to Greece between October and December and 466,000 on the Western Balkan route, notably people re-entering the European Union at the Croatian border from non-EU Serbia.
