Iran is running out of time to show the international community its readiness to continue a dialogue on its nuclear program, White House press secretary Robert Gibbs has said.

The Islamic Republic's state television reported on Sunday that Iran plans to build ten new uranium enrichment facilities. It said Iran's government instructed the country's nuclear organization to start building five new plants and outline locations for another five within two months.

"If true, this would be yet another serious violation of Iran's clear obligations under multiple UN security council resolutions, and another example of Iran choosing to isolate itself," Robert Gibbs said in a statement.

Gibbs said "the international community has made clear that Iran has rights, but with those rights come responsibilities."

"Time is running out for Iran to address the international community's growing concerns about its nuclear program," he added.

Iran's parliament on Sunday demanded that the government reduce cooperation with the International Atomic Energy Agency following Friday's resolution by the UN nuclear watchdog condemning Iran's work to build a new nuclear power plant.

The IAEA passed on Friday its first resolution since early 2006, censuring Iran for withholding information on its controversial nuclear program, and urging it to freeze construction of its newly revealed uranium enrichment facility in Qom.

The resolution was endorsed by Germany, Britain, China, France, Russia and the United States, the six nations involved in long-running nuclear negotiations with Iran.

The Iranian lawmakers condemned the resolution and urged the government to quickly draft a plan to reduce cooperation level with the UN nuclear watchdog.

Director General Mohamed ElBaradei told the IAEA board of governors on Thursday that his inquiry into allegations that Iran is seeking to build nuclear weapons had reached "a dead end" as Tehran was not cooperating.

Tehran is already under three sets of UN sanctions for refusing to halt uranium enrichment. Iran insists it needs nuclear technology to generate electricity, claiming the right under the Nuclear Non-proliferation Treaty.
