North Korea demands joint probe with U.S. into Sony hack

North Korea proposed a joint investigation with the United States on the cyberattack against Sony Pictures, calling the charge by the FBI that it was behind the hack “slander,” state media said on Saturday.

An unnamed spokesman of the North’s foreign ministry said there would be “grave consequences” if Washington refused to agree to the joint probe and continued to accuse the North, the official KCNA news agency reported.
