Nuclear talks between Iran, 6 world powers enter last day, aim to set future agenda

Iran and six world powers are wrapping up a series of meetings meant to agree on agenda for a comprehensive deal that reduces concerns about Tehran's nuclear ambitions.

Expectations of major progress from this round are modest as the third day of talks end Thursday because the two sides have widely differing demands.

The six want Tehran to agree to significant cuts in its nuclear program to reduce concerns it could be turned quickly to weapons use. Iran is opposed, saying it has no interest in such weapons, but must come to agreement if it wants a full end to sanctions crippling its economy.
