There are signs good progress is being made in talks aimed at limiting Iran's nuclear ambitions.

Iran's foreign minister has taken the unusual step of putting his country's views out with a YouTube posting.

Javad Zarif said getting an agreement would open new ways to address other problems...including extremism in the Middle East.

But he agrees there is work to do to meet a deadline for a deal this week.

"Despite some differences that remain, we have never been closer to a lasting outcome. Getting to yes, requires the courage to compromise," he said.
