Secretary of State Hillary Clinton is putting pressure on Iranian leaders over their country's nuclear program.
Clinton said Monday that the Obama administration believes imposing new international sanctions on Iran's top officials is the best way to curb their nuclear ambitions.
"It is clear that there is a relatively small group of decision makers inside Iran," she said. "They are in both political and commercial relationships, and if we can create a sanctions track that targets those who actually make the decisions, we think that is a smarter way to do sanctions."
The Obama administration has not imposed any new sanctions yet, but Clinton said they are headed in that direction.
