Prime Minister Alexis Tsipras: 'An absolutely no to division'

Greece's Prime Minister Alexis Tsipras has urged thousands of supporters to "turn their backs on their oppressors" and vote "No" in Sunday's bailout referendum.

"Nobody has the right to threaten to cut down Greece from its natural geographic body," he said as he addressed the crowd.

The ballot may decide Greece's future in Europe's single currency.
