Greek Finance Minister Yanis Varoufakis accused Athens' creditors of "terrorism" – the day before the nation votes in the bailout referendum. Varoufakis said in Spain's El Mundo newspaper that "what they're doing with Greece has a name -- terrorism. What Brussels and the troika want today is for the 'yes' (vote) to win so they could humiliate the Greeks." Greece is set to vote in the bailout referendum on Sunday July 5. If Greeks vote "No" – "OXI" in Greek – it could spell the end of country using the euro, because a "No" vote means they reject the demands of the country's European creditors. If Greeks vote "Yes" – "NAI" in Greek — it means citizens accept the terms of the bailout deal that were tabled prior to June 30, and it is then likely that Greece will stay in the Euro and work through new terms of the bailout programme. On Friday night, my colleague Mike Bird was one of the tens of thousands of people that turned up in Athens' Syntagma Square for the "No" campaign rally. Prime Minister Alexis Tsipras made a speech and Varoufakis also attended. On the same day, Channel 4 released an interview with Varoufakis where he said the European governments with whom he is negotiating have offered him a deal he is willing to sign. There is a condition, however. Greece must first vote "no" in the referendum on accepting Europe's bailout conditions, on Sunday. It is not clear what the terms of the deal are, and Channel 4's video ends before Varoufakis describes them.Join the conversation about this story » NOW WATCH: Forget the Apple Watch — here's the new watch everyone on Wall Street wants
