URGENT ¥¥¥ Iran to present world powers with new nuclear offer

Iran will present world powers at crunch nuclear talks in Kazakhstan with a new offer on ending the crisis, an Iranian source said Tuesday.

"We have prepared our own offer with several different versions," said the Iranian source. "Which version we present depends on what the 5+1 (world powers) put forward," added the source, saying Iran could envisage halting the enrichment of uranium to 20 percent if all international sanctions against it were dropped.
