ATHENS - The Greek government is in last-minute talks over whether to accept an offer that would let Greece repay part of its debt, local media say.
Greece is hours away from a deadline to repay a €1.6bn (£1.1bn) loan to the International Monetary Fund (IMF) - one it may miss.
One of Greece's creditors, the European Commission (EC), said it made a last-minute proposal of reforms on Monday.
If Athens accepts the deal, it will free up cash to repay the €1.6bn.
A European Commission spokesman said the EC's president, Jean-Claude Juncker, was called by Greek Prime Minister Alexis Tsipras on Monday night.
Mr Juncker then offered Greece the latest deal, with a midnight deadline. That has since expired.
However, Greek media say the government is still in talks over the offer.
The national broadcaster, ERT, said on Tuesday morning that discussions about the proposals were taking place "at the highest level" in Athens.
Greece's chief negotiator with its creditors, Euclid Tsakalotos, told the BBC's Europe editor Katya Adler he expected more proposals to be made.
Long queues of people are continuing to snake from many ATMs, with withdrawals capped at just €60 a day.
Up to 1,000 bank branches will re-open from Wednesday to allow pensioners - many of whom do not use bank cards - to withdraw up to €120.
