Iran's president is holding out hope that Tehran and world powers may still be able to reach a deal on the country's controversial nuclear program before the Nov. 24 deadline.

Hassan Rouhani says Iran has the "political will" to reach the deal with the six nation group — the five permanent members of the U.N. Security Council plus Germany — although significant differences remain that require negotiations.

Rouhani spoke on national television late on Monday, in remarks that somewhat contrasted those of senior Iranian nuclear negotiator, Abbas Araghchi, who on Friday said the talks could be extended.

The talks were already extended once earlier this year. They reportedly remain stuck over the size and output of Iran's uranium enrichment program, a possible pathway to nuclear arms.
