(CNN)  -- Pakistani President Asif Ali Zardari denied his nation was involved in last week's deadly attacks on Mumbai, India, and told CNN on Tuesday he's seen no evidence that a suspect in custody is a Pakistani national as Indian officials claim. Pakistani President Asif Ali Zardari says he believes the Mumbai attackers were "stateless actors." "I think these are stateless actors who have been operating all throughout the region," Zardari said on CNN's "Larry King Live" in an interview set to air Tuesday night. "The gunmen plus the planners, whoever they are, [are] stateless actors who have been holding hostage the whole world."
