BERLIN, Feb 17 (Reuters) - German Finance Minister Wolfgang Schaeuble on Tuesday appeared cool on a report that Greece intends to ask for an extension of its loan agreement with the euro zone, telling broadcaster ZDF it was not up for discussion.

A source told Reuters earlier on Tuesday that Athens' new government would request up to a six-month extension of its loan agreement but the conditions were still under negotiation.

Asked about the report, Schaeuble said he did not know anything more, but added: "There is no loan agreement for Greece, there is a bailout programme."

"It's not about extending a credit programme but about whether this bailout programme will be fulfilled, yes or no," Schaeuble said in the ZDF published online.
