Iran's state radio is reporting that the country will respond Friday to an international proposal on its nuclear program. The report says Iran's top nuclear negotiator, Saeed Jalili, told European Union foreign policy chief Javier Solana by phone that Iran would present its response Friday. It did not elaborate on details of the response. The report also says the two officials agreed in the conversation to resume their talks in the second half of July. Solana last met with Iranian officials in mid-June, trying to get Tehran to accept the incentives offer. In June, the EU offered economic incentives if Iran halts uranium enrichment.
