Foreign Minister Avigdor Lieberman said in an interview on Wednesday that Israel will not bow to U.S. and Russian pressure in deciding whether to attack Iran.
Speaking on Channel 2 news, Avigdor Lieberman rebuffed suggestions that American and Russian warnings against striking Iran would affect Israeli decision making, saying the decision "is not their business."
He said "the security of the citizens of Israel, the future of the state of Israel, this is the Israeli government's responsibility."
Russia warned Israel not to attack Iran over its nuclear program on Wednesday, saying that military action would have catastrophic consequences.
"Of course any possible military scenario against Iran will be catastrophic for the region and for the whole system of international relations," Deputy Foreign Minister Gennady Gatilov said.
"Therefore I hope Israel understands all these consequences ... and they should also consider the consequences of such action for themselves," Gatilov said at a news conference.
This week, the U.S.?military chief said an Israeli attack would be "not rudent."
Meanwhile, a top UN nuclear official said on Wednesday his team could "could not find a way forward" in attempts to persuade Iran to talk about suspected secret work on atomic arms.
Herman Nackaerts of the International Atomic Energy Agency says the talks in Tehran were inconclusive, although his mission approached the talks "in a constructive spirit."
Nackaerts spoke to reporters at Vienna airport shortly after returning from the Iranian capital.
An IAEA statement published overnight already acknowledged the talks had failed.
Iran denies it has experimented with nuclear arms programs but has refused to cooperate with an IAEA probe on the issue for nearly four years.
