"I want to reiterate that Italy fully supports action to help Turkey," Padoan told a news conference in Brussels.

"We think however that it needs to be more clearly defined," he said. "We believe that A, the resources can be found within the EU budget and B, there must be a clear understanding of how the resources are used."

Jeroen Dijsselbloem told a separate news conference on Friday that Italy blocked funding of 3 billion euros ($3.27 billion) pledged last year by the bloc to help Turkey care for Syrian refugees at a meeting the Dutchman chaired.
