JERUSALEM - United States National Security Advisor James Jones said Friday the administration was discussing how to jump-start the lagging Middle East peace process, but did not have a new plan to offer.

Speaking to reporters accompanying U.S. President Barack Obama back to Washington from Prague, Gen. James Jones said, there's been no decision made regarding a concrete Middle East peace plan.

Ealier this week there had been reports saying that the administration was poised to offer a new U.S. peace proposal to Israel and the Palestinian Authority that would build on understandings reached at Camp David, Maryland, in 2000

Jones said the Mideast strategy came up during a meeting Obama recently had with a half-dozen former national security advisers, and that the discussions are ongoing don't intend to surprise anybody.

Earlier Friday, Lebanese Prime Minister Saad Hariri called for a "world leadership" to force all the parties to the Middle East conflict to negotiate, describing U.S. President Barack Obama as the "ideal person" to head the effort.

Israel does not have an "authentic interest" in reaching a "wide- ranging and fair" peace arrangement with the Arab world, Hariri claimed at an economic forum on the second day of his official visit to Spain.

The Obama administration has a sincere commitment to promote peace, Hariri said, also stressing the importance of the Spanish European Union presidency.
