TEHRAN, Iran — Iran said Saturday that a package of incentives offered by six countries was "out of the question" because it includes a demand for the country to suspend uranium-enrichment activities.

The European Union foreign-policy chief, Javier Solana, presented the proposal to Iranian authorities Saturday on behalf of the U.S., China, France, Germany, Britain and Russia. He told reporters in Tehran, the Iranian capital, that the offer was "generous and comprehensive and a starting point for real negotiations" on the country's nuclear program.

But Iranian officials said even before the offer was formally made that they would not consider any proposal that included halting the country's uranium enrichment as a condition to talks.
