URGENT ¥¥¥ Kerry urges 'strong' action on N. Korea in sign to Iran

US Secretary of State John Kerry Wednesday urged "strong, credible" action from world leaders after North Korea's nuclear test to show Iran that they are serious about non-proliferation.

"This is about proliferation and this is also about Iran ... because they're linked," Kerry said after talks with Jordanian Foreign Minister Nasser Judeh.

"Just as it is impermissible for North Korea to pursue this kind of reckless effort, so we have said that it is impermissible with respect to Iran. And what our response is to this, will have an impact on all other proliferation efforts."
