ALMATY, Kazakhstan (AP) — World powers have begun their fourth round of high-level talks with Iranian officials in hopes of stopping the Islamic regime's nuclear program from making atomic weapons.
It's not clear if the talks will conclude Tuesday night or stretch into a second day.
Negotiators from the six world powers — United States, Russia, China, Britain, France and Germany — will offer Iran some small new relief from harsh international sanctions to entice Tehran into stopping enriching uranium close to a weapons-grade level.
Interfax news agency cited Russia's envoy at the talks as saying easing of sanctions is possible only if Iran can assure the world that its nuclear program is for exclusively peaceful purposes.
