The United Nations has called for a massive resettlement of Syrian and other refugees within Europe.

Several thousand people marched through the centre of Athens in Greece, calling for Europe to open its borders.

The march was joined by some of the migrants stranded in the Greek capital by the decision made by some Balkan countries to close the borders to them.
