Top eurozone officials on Friday kept up the

pressure on Greece to deliver new bailout proposals so as to avoid

bankruptcy, as Prime Minister Alexis Tsipras collected some pledges

of help during a visit to Russia, dpa reported.

Fears are rife that Greece is about to run out of money, after it has

struggled for months to agree with its creditors on economic reforms

that would unlock 7.2 billion euros (8.1 billion dollars) in bailout

aid for Athens.

Time is now running out as the European part of the Greek bailout is

expiring on June 30, on the same day when the country is supposed to

repay 1.6 billion euros to the International Monetary Fund (IMF).

'We are close to the point where the Greek government will have to

choose between accepting what I believe is a good offer of continued

support or to head towards default,' EU President Donald Tusk warned

in a video message released Friday.
