US Secretary of State Hillary Clinton said Sunday the United States is "going to look at" putting North Korea back on its list of countries that sponsor terrorism following Pyongyang's nuclear and missile tests. In an interview with a local TV, the top US diplomat was asked for a response to a letter from several US senators asking President Barack Obama to put Pyongyang back on the terror list, from which it was removed in October 2008 under former president George W. Bush. "Well, we're going to look at it," she said. "There's a process for it. Obviously we would want to see recent evidence of their support for international terrorism," she added.
