TEHRAN, Iran (AP) — Iran’s president said on Monday that Tehran and world powers may still be able to reach a final deal on the country’s controversial nuclear program before the Nov. 24 deadline.

The remarks by moderate President Hassan Rouhani came as Iran and the six nation group — the five permanent members of the U.N. Security Council plus Germany — are to begin another round of talks in Vienna on Tuesday, in the countdown to the November deadline for a final, comprehensive deal.
