Greek debt crisis: fresh uncertainty as euro zone creditors call for changes

International creditors demanded politically sensitive changes to Greek Prime Minister Alexis Tsipras' tax and reform proposals on Wednesday, adding fresh uncertainty to talks aimed at unlocking aid to avert a debt default next week.

The leftist Tsipras spent all afternoon in a meeting with the heads of the European Commission, the International Monetary Fund, the European Central Bank and euro zone finance ministers, but officials said there was no breakthrough.
