US, Russia Pledge to Cooperate on Syria

U.S. Secretary of State John Kerry says the United States and Russia can make a significant difference in Syria if they work together. He spoke Tuesday in Moscow, where he met with top Russian officials to discuss Russia's role in Syria and Ukraine. Zlatica Hoke reports the two sides are trying to iron out their disagreements on Syria before meeting with other world powers Friday in New York, where they hope to adopt a United Nations resolution endorsing the Syria peace process.
