Iran and EU Leaders Issued Joint Statement on Iran Nuclear Talks

After failing to meet Tuesday's deadline, negotiators in Switzerland today announced a "tentative agreement" to limit Iran's nuclear program. Federica Mogherini , European Union's High Representative for Foreign Affairs, said EU sanctions against Iran will end.

Correspondent Laura Rozen is in Lausanne, Switzerland for Al-Monitor, an online news outlet focused on the Middle East. Although optimistic, George Perkovich, vice president for studies and director of the Nuclear Policy Program at the Carnegie Endowment for International Peace, says more clarity on the role of the IAEA is needed, and what criteria it will assess in saying Iran has taken all key nuclear-related steps.
