BRUSSELS (Reuters) - Euro zone finance ministers' talks on a bailout for Greece remain "very difficult" and will resume at 9.00 a.m. GMT on Sunday after breaking overnight, Eurogroup President Jeroen Dijsselbloem told reporters.

Finnish Finance Minister Alexander Stubb said talks were "making good progress". Other ministers declined comment as they left around midnight (2200 GMT) after nine hours of talks at EU offices in Brussels.
