Referendum campaign posters that reads "No" in Greek

Referendum campaign posters that reads "No" in Greek are seen as people line up at an ATM outside a National Bank branch during a referendum vote in Athens, Greece, July 5, 2015. Greece voted on Sunday on whether to accept more austerity in exchange for international aid, in a high-stakes referendum likely to determine whether it leaves the euro-currency area after seven years of economic pain.
