EU gives Greece deadline on borders

The European Union has given Greece three months to fix its border controls, in a move that could allow other Schengen zone states to maintain internal border controls.
Two weeks ago, a draft report found that Greece had "seriously neglected" its obligations to control the external frontier of the border-free zone.
Some EU states have re-imposed border controls on a temporary basis.
More than 850,000 migrants and refugees arrived in Greece last year.
