TEHRAN, Iran – To shouts of “Death to America,” Iran’s Parliament unanimously approved the outline of a bill yesterday that would require the government to resume uranium enrichment, legislation likely to deepen an international dispute over Iran’s nuclear activities.

Still, Iran’s top nuclear negotiator, Hossein Mousavian, said there was a 50% chance of a nuclear compromise with European nations.

He ruled out an indefinite suspension of key enrichment activities – a concession that European negotiators have sought – but suggested Iran would consider calling a halt to building more nuclear facilities.

The talks with the Europeans aim at averting a standoff over Iran’s nuclear weapons program at a November 25 meeting of the U.N. nuclear watchdog.

The Europeans have offered to provide nuclear fuel and technology if Tehran reins in its ambitions to develop its own fuel – by creating enrichment facilities that can be used for peaceful purposes or for creating weapons.

Parliament speaker Gholam Ali Haddad Adel called yesterday’s vote a message to the world.

“The message of the absolute vote for the Iranian nation is that the Parliament supports national interests,” he said. “And the message for the outside world is that the Parliament won’t give in to coercion.”

The legislation said the government is “required to make use of scientists and the country’s facilities…in order to enable the country to master peaceful nuclear technology, including the cycle of nuclear fuel.”

Another vote is expected on the bill when details are worked out, but that is usually a formality. A date for the second vote was not immediately set.
