(CNN) -- Pakistani President Asif Ali Zardari on Tuesday insisted that his country's nuclear arsenal is "definitely safe," despite growing concerns about recent gains by the Taliban along the country's border with Afghanistan. Pakistani President Asif Ali Zardari insists his country's nuclear arsenal is "definitely safe" from militants. In an interview with CNN's Wolf Blitzer, Zardari responded to the fact that the United States doesn't know the locations of all of Pakistan's nuclear sites. He also addressed the Obama administrations concern over whether the weapons are vulnerable to Taliban fighters who are gaining control of some border regions. "They can't take over," Zardari said, referring to militants. "We have a 700,000 (person) army -- how could they take over?"
