Eurozone nations will hold a summit on Tuesday to discuss the Greek referendum result, EU President Donald Tusk said, after the German and French leaders called for a meeting.

"I have called a EuroSummit Tuesday evening at 18h (1600 GMT) to discuss situation after referendum in Greece," Tusk said on Twitter on Sunday after Greek voters said a resounding 'No' to creditor demands for further austerity in return for bailout funds.
