April 9, 2009 Iran to Decide on Nuclear Talk Offer ------------------------------------ http://enews.voanews.com/t?ctl=23774BF:A6F02AD83191E16074DEB22F4F7AB19FC030207A0BD70133& Aide to President Mahmoud Ahmadinejad says Tehran will decide how to respond after it examines details of offer Mahmoud Ahmadinejad (file photo)An aide to Iranian President Mahmoud Ahmadinejad says Tehran will review the offer of nuclear talks made by the United States and five other world powers. The aide, Ali Akbar Javanfekr, said Thursday that Iran will decide how to respond after it examines the details of the offer. Senior diplomats of the five permanent Security Council member states: U.S., Russia, China, France and Britain and Germany met in London Wednesday and said they would ask European Union chief diplomat Javier Solana to invite Iran to a meeting soon to seek a diplomatic solution to the "critical" nuclear issue. In their statement, the nations strongly urged Iran "to engage seriously with all of us in a spirit of mutual respect." U.S. Secretary of State Hillary Clinton said the United States will be a full participant in major power talks with Iran over its disputed nuclear program. She said "pursuing very careful engagement" on a range of issues makes sense, adding that there is "nothing more important" than trying to convince Iran to cease its efforts to obtain a nuclear weapon. The United States does not normally engage with Iran, but President Barack Obama has indicated a willingness to open dialogue. Iranian media has reported that Mr. Ahmadinejad is expected to announce a new stage in the country's nuclear fuel production abilities as it celebrates "National Nuclear Day" later Thursday. The U.N.'s atomic agency has not been able to determine whether Iran's Arak heavy water nuclear reactor, which Tehran says is designed for peaceful research, can be reconfigured for military use. Mr. Ahmadinejad repeated Wednesday that Iran is not seeking a nuclear weapon. Iran is under three sets of international sanctions over its nuclear program, including its enrichment of uranium. Low-grade enriched uranium is needed to operate nuclear power plants. The element must be enriched to a higher grade to be used for weaponry.
