Prime Minister Binyamin Netanyahu said on Monday that the international community must set a “clear red line” in order to avoid a war over Iran's controversial nuclear program, AFP reported.

“This is a brutal regime that is racing ahead with its nuclear program because it doesn't see a clear red line from the international community,” the report quoted Netanyahu as having said at a meeting with Israeli and U.S. servicemen wounded in conflict.

He added, “And it doesn't see the necessary resolve and determination from the international community. The greater the resolve and the clearer the red line, the less likely we'll have conflict.”

Netanyahu was repeating remarks he made at the weekly Cabinet meeting on Sunday, where he said, “I think that we should speak the truth -- the international community is not drawing a clear red line for Iran and Iran doesn't see determination from the international community to stop its nuclear program.”

His remarks on Monday came after a report in the Israeli daily Yediot Aharonot, which said that senior officials in the Obama Administration sent a message to Tehran in the past few days, according to which the U.S. does not intend to join Israel's side if it decides to attack the Iranian nuclear installations on its own.

According to the report, the U.S. sent the message to Iran in order to avoid an Iranian military response that would target U.S. installations in the Gulf region.

The White House later officially denied having held secret talks with Iran over a possible attack by Israel.

“The report is false and completely incorrect,” said White House Spokesman Jay Carney. “And we don't talk about hypotheticals,” he added.

Meanwhile, the New York Times reported on Monday that the U.S. may declare certain "red lines" that would trigger a U.S. attack if crossed by Iran.

The Obama Administration is trying to put pressure on Iran through tightening economic sanctions, placing of missile defense systems in Qatar, and weighing the launching of more cyber-attacks like Stuxnet, the newspaper reported. In addition, the administration is considering "new declarations by President Obama about what might bring about American military action, as well as covert activities that have been previously considered and rejected."
