Paris: Germany and France called on Greece to make detailed proposals to revive bailout talks, a day after Greek voters defiantly rejected creditors' demands for further austerity, plunging Europe into crisis.

With Greece's economy gasping for air, the authorities extended an eight-day bank closure amid fears cash machines in the country were running dry. The European Central Bank, which has been keeping Greek lenders afloat, meanwhile announced it would maintain its liquidity lifeline to Greek banks, but made it harder for them to access the funds by tightening collateral terms.
