By Lefteris Papadimas and Leigh Thomas ATHENS/PARIS (Reuters) - Greece said on Tuesday it had sent a comprehensive reform proposal to its international creditors, urging them to be realistic and accept the plan to clinch a long delayed deal to release frozen aid before Athens runs out of cash. The announcement by leftist Prime Minister Alexis Tsipras came hours after leaders of Germany, France and the lending institutions held emergency talks on the Greek debt crisis in Berlin in a sign of top-level concern about the impasse. It appeared to be an attempt to pre-empt a take-it-or-leave-it offer by the creditors and to show Greek voters that Athens, too, is putting forward proposals.
Oil prices rose on Tuesday in response to a weaker dollar and expectations that OPEC producers will maintain their group production target at its current level and resist pressure for an increase. Brent crude oil for July was up 40 cents at $65.28 a barrel by 1030 GMT. Ministers from the Organization of the Petroleum Exporting Countries (OPEC), responsible for more than a third of the world's oil output, meet in Vienna on Friday to decide on production policy for the next six months.
