JERUSALEM - Prime Minister Ehud Olmert told a powerful parlimanetary panel on Monday that Israel rejects "no options" to block Iran from obtaining nuclear weapons, a meeting participant said, in the Israeli leader's clearest indication yet that he is willing to use military force to do so.

"Israel clearly will not reconcile itself to a nuclear Iran," the meeting participant quoted Olmert as telling parliament's Foreign Affairs and Defense Committee. "All options that prevent Iran from gaining nuclear capabilities are legitimate within the context of how to grapple with this matter."

Olmert addressed the panel just days after discussing Iran's nuclear ambitions in face-to-face talks with U.S. President George W. Bush in Jerusalem.

The meeting participant spoke on condition of anonymity because the session was closed.
