"As the President says, it's time for them to behave, to listen to the world community and to set aside their nuclear ambitions, their ballistic missile ambitions, and be willing to join the family of nations," Pence told CNN Tuesday.

Tensions on the peninsula have ratcheted up in recent weeks amid saber-rattling from the US and North Korea and analysts' warnings that North Korea is preparing for a sixth nuclear test.
