US President Barack Obama said he is confident that Pakistan has secured its nuclear weapons.
Obama, however, reiterated that he was concerned about global nuclear security, not just in Pakistan.
In an interview with the New York Times, President Obama said his new approach to nuclear non-proliferation is different from that of the Bush administration.
Obama is scheduled to announce the new US policy for non-proliferation later Tuesday.
When asked what he had done specifically to ensure Pakistan’s nuclear weapons’ safety, Obama said he was not going to divulge details about Pakistan’s nuclear programme.
Obama explained that his biggest concerns were about securing loose nuclear material, which the terrorists were more likely to obtain

A nuclear summit is scheduled to be held in the US capital on April 12 and 13, aimed at achieving a global consensus on limiting proliferation and preventing terrorists from acquiring nuclear technology.
