Greek Prime Minister Alexis Tsipras said on Thursday that Greece and EU heavyweights Germany and France had agreed that last-ditch bailout talks must reach a "viable solution" as negotiations broke-up without a deal.

"The European leaders realised that we must offer a viable solution and the chance for Greece to return to growth," Tsipras said after talks with German Chancellor Angela Merkel and French President Francois Hollande on the sidelines of an EU-Latin America summit in Brussels.
