U.S. nuclear pact hurts Iran:  Khamenei

• Ayatollah Ali Khamenei argues U.S. nuclear agreement proposal is against national interest.

• The disagreement stems from Iran’s ability to continue enriching uranium.

• Iran has held five rounds of talks since April to replace the abandoned deal with major powers.

• Iran received “elements” of the U.S. proposal through Omani mediators.

• Khamenei cites 1979 Islamic revolution ideals of independence and self-reliance.

• Iran’s uranium enrichment is a major point of contention.
