Iran demanded today that the European Union submit its proposals on solving the dispute over Tehran's nuclear program by Monday and rejected any talk of a delay. A spokesman for the Supreme National Security Council said ambassadors from Britain, Germany, and France -- the EU trio negotiating with Iran on its nuclear program -- had asked that an August 1 deadline for their proposals be extended to August 7. The EU trio plans to offer Tehran a package of incentives to encourage the Islamic Republic to respect its nuclear commitments. But Iranian nuclear negotiators said today in Tehran that they are demanding that the EU submit its proposals by the original deadline. AFP quotes a spokesman for the Foreign Office in London as denying any such deadline exists. Iran's newly elected president, hard-liner Mahmood Ahmadinejad, takes office on Wednesday.
