Hours before the deadline for the payment, Prime Minister Alexis Tsipras asked the other nations that use the euro to provide another bailout, which would buy time for Athens to renegotiate its crippling debt load.
Chancellor Angela Merkel of Germany said earlier in the day that no deal with Mr. Tsipras’s government could be negotiated until after a Greek referendum scheduled for Sunday. Greek voters will be asked to accept or reject an offer made last week by the country’s creditors.
