Greek PM Tsipras telephoned Italian PM Renzi: Italy government source

ROME (Reuters) - Greek Prime Minister Alexis Tsipras telephoned Italian premier Matteo Renzi on Tuesday, an Italian government source said, as EU authorities made a last-minute offer to salvage a bailout deal with Athens.

Euro zone finance ministers are due to speak later on Tuesday as the clock ticks toward a midnight deadline for the expiration of billions of euros in locked-up bailout funds.
