ATHENS, Greece — It’s crunch time for Greece, with the European part of its international bailout expiring Tuesday and with it any possible access to the remaining rescue loans that it needs to pay its debts. Without an 11th-hour deal, the government is unlikely to repay a debt of about 1.6 billion euros ($1.9 billion) to the International Monetary Fund also due Tuesday — a move that would amount to default and would increase fears the country could fall out of the euro currency bloc. With banks shut and Greeks limited to cash withdrawals of 60 euros ($67) per day, long lines formed once more at ATM machines.
