Washington is "hallucinating" if it thinks Iran will scrap its nuclear fuel production plans in return for economic incentives, a senior Iranian official was quoted as saying today.
The United States offered the incentives in support of the European Union which is negotiating with Tehran to try to persuade it to give up sensitive nuclear activities.
"US officials are either unaware of the substance of the talks or (they are) hallucinating," Sirus Naseri, a senior member of Iran's nuclear negotiating team, told the official IRNA news agency.
Iran says it needs atomic technology to generate electricity and will never use it to make bombs, as the United States fears.
London's Sunday Times said Israel had drawn up plans for a combined air and ground attack on Iranian nuclear installations if diplomacy fails to halt Tehran's atomic program.
The newspaper said Israeli Prime Minister Ariel Sharon and his inner cabinet had given "initial authorization" for a unilateral attack at a private meeting last month.
Israel, which bombed Iraq's Osirak nuclear reactor in 1981, played down the report. Iran has said it will respond vigorously to any attack on its nuclear plants.
Washington gave practical backing for the EU's diplomatic approach Friday, offering to allow Iran to begin talks on joining the World Trade Organization (WTO) and consider letting it buy civilian airline parts if it ceased all activities that could produce fuel for nuclear power plants or atomic weapons.
Washington and the EU have warned Iran it faces referral to the U.N. Security Council, which could impose economic sanctions, if it fails to allay fears it wants the bomb.
