Western powers hope to win Russian and Chinese backing for rebuking Iran at the U.N. nuclear agency next week over Tehran's failure to address mounting fears that it is secretly bent on acquiring nuclear weapons capability, diplomats say.
A wide majority of Israelis either oppose an Israeli strike on Iran or would favor an attack only if it was carried out with U.S. agreement, an opinion poll showed on Thursday.
An Israeli attack on Iran is "very far off," Israeli Defense Minister Ehud Barak said.
Israel test-fired a ballistic missile on Wednesday, Israel Radio said, amid a heightened public debate over the possibility of an Israeli attack against Iran's nuclear program.
Israeli leaders have not asked the United States for approval to attack Iran for fear Washington will turn them down, according to a news report.
Vice President Joe Biden's statement that Israel can decide on its own whether to strike Iran's nuclear sites should not be construed as an American "green light" for such an action, the State Department said on Monday.
