Euro group ministers were losing patience as the Greek crisis talks enter a critical stage, Finance Minister Edward Scicluna said this afternoon.

Looking exasperated, Prof. Scicluna told reporters in Brussels that Greece had submitted fresh proposals just half an hour before this afternoon's meeting.

Urgent talks between Greece and the country's international lenders have so far ended without agreement on how to solve its debt crisis.

"We merged them just before coming here. We want to know what has been deleted and what has been added. At least we are now talking from the same book book because there's a specific text. But I don't know what the disagreements are because they didn't come merged together," Prof. Scicluna said.

However the minister said that at this stage nobody dared forecast whether an agreement was in the offing.
