Grecia alla vigilia del referendum

Demonstrators shout slogans against austerity during a protest in support of Greece in front of the European Union office in Nicosia, Cyprus, July 4, 2015. In a tumultuous week, Greece has closed its banks, introduced capital controls and become the first developed country to default on an International Monetary Fund loan. Talks with its creditors over a reforms-for-cash deal are deadlocked, and some analysts think Sunday’s referendum will determine Greece’s future in the euro zone. REUTERS/Yiannis Kourtoglou
