The European Union said on Monday that world powers will present Iran with an updated and "good" offer at talks this week on its nuclear program.

"We have prepared a good and updated offer for the talks, which we believe is balanced and a fair basis for constructive talks," said the spokesman for EU foreign policy Chief Catherine Ashton.
"The offer addresses international concerns... on the nature of the Iranian nuclear program, but is also responsive to Iranian ideas," said the spokesman, Michael Mann.

"We hope that Iran will seize this opportunity and come to the talks with flexibility and commitment to make concrete progress towards a confidence-building step."

A source close to the negotiations said the offer would urge Iran to halt enriching uranium to 20 percent, shut down its Fordo uranium enrichment plant and send abroad all uranium that allegedly have been enriched to 20 percent.

"This still forms the basis of the demands of the 5+1 group," said the source who asked not to be identified.

Iran confirms its program is for peaceful ends only insisting that is its right under the Nuclear Nonproliferation Treaty (NPT) while Israel, which is believed to be the sole nuclear power in the Middle East with more than 200 nuclear heads, is not a signatory for this treaty.
