US President Barack Obama warned against imposing more sanctions against Iran, as Zionist Prime Minister Benjamin Netanyahu said he was ‘unimpressed’ by a IAEA report on the Islamic Republic nuclear program.

"What we have done is seen the possibility of an agreement in which Iran would halt advances on its program," Obama told a news conference a week after talks involving the United States and Iran in Geneva.

"We can buy some additional months in terms of their breakout capacity. Let's test how willing they are to actually resolve this diplomatically and peacefully," he said.

Obama said that US-led sanctions have "crippled" Iran's economy and that a deal would offer only "very modest relief at the margin."

He said an agreement would not, for now, ease the two main measures enacted by Congress -- sweeping restrictions on Iran's vital oil exports and banking system.

Obama said he was telling Congress that his intention "always was to bring the Iranians to the table so we could resolve this issue peacefully."

"No matter how good our military is, military options are always messy, are always difficult, always have unintended consequences, and in this situation are never complete in terms of making us certain that they don't then go out and pursue even more vigorously nuclear weapons in the future," he said.

"If we're serious about pursuing diplomacy, there's no need for us to add new sanctions on top of the sanctions that are already very effective and that brought them to the table in the first place," Obama said.

Netanyahu ‘Unimpressed’
Meanwhile, Netanyahu said he was unimpressed by a report from the UN's International Atomic Energy Agency on Thursday that Iran had frozen its nuclear activities.

“I am not impressed by the report published this evening," Netanyahu was quoted by his office as saying.
"Iran does not need to expand its program because it already possesses the necessary infrastructure for building a nuclear weapon,” the Zionist leader claimed.

IAEA said that, in the past three months, only four new centrifuges had been installed at Iran's Natanz plant, compared with 1,861 in the previous period.
