Iran will give its response to a nuclear package backed by six nations to ambassadors in Tehran at 4 p.m. (1230 GMT) on Tuesday, a local television reported.

"There would be a meeting at 4 p.m for the ambassadors of the six world powers whose countries have proposed the package," said the TV report.

Iran's top nuclear negotiator Ali Larijani will give the ambassadors the official response in writings at the meeting, which will be held at Iran's Supreme National Security Council, it added.

Meanwhile, Larijani will make some comments after giving the response, according to a source close to the issue. Iran has promised to give an official response by Tuesday to the package of proposals, which have been agreed on by the United States, Russia, China, France, Britain and Germany. Since the United States has no diplomatic relations with Iran, the Swiss ambassador, who's embassy takes care of U.S. interests in Iran, will represent the United States to join the other five ambassadors to receive the Iranian response, according to media reports.

Russia, China, France, Britain and Germany all have ambassadors in the Iranian capital Tehran.

On June 6, EU foreign policy chief Javier Solana presented Iran with the package agreed on by the five permanent members of the UN Security Council plus Germany concerning the Iranian nuclear issue. The package, designed to defuse the current tensions over Iran's nuclear program, includes both incentives aimed at persuading Iran to suspend uranium enrichment and possible sanctions if Iran does not comply.

On Monday, Iran's Supreme Leader Ayatollah Ali Khamenei said that Iran would continue its nuclear energy work. Deputy Director of Iran's Atomic Energy Organization Mohammad Sa'eedi also said Monday that suspension of uranium enrichment was "practically impossible" even though the UN Security Council has made such a demand.

The Security Council has recently adopted a resolution urging Tehran to suspend by Aug. 31 all enrichment-related and reprocessing activities, including research and development, or face the prospect of sanctions.

The United States has accused Iran of secretly developing nuclear weapons under a civilian front, a charge categorically denied by Tehran which says that its nuclear program is for peaceful purposes.
