Iran nuclear talks gets into serious phase: EU foreign policy chief spokesperson

Complicated talks on Iran nuclear program are getting into a "a serious phase," European Union foreign policy chief Catherine Ashton said Thursday through her spokesperson.

Michael Mann, Ashton's spokesperson, told a press conference that "concrete progress" is hoped from ongoing talks between the P5+1 (Britain, China, France, Russia, United States plus Germany) and Iran.

Mann reiterated that the goal was to achieve from the Iranians the assurance for the international community of the purely peaceful nature of their nuclear program.

"We can achieve that if there is engagement from the Iranian side, and we can have an agreement at the end of the negotiating process that is fully verifiable," he said.
