North Korea on Saturday called for a joint investigation into a crippling cyber attack on Sony Pictures, claiming it had nothing to do with it.
"As the United States is spreading groundless allegations and slandering us, we propose a joint investigation with it into this incident", the North's foreign ministry said.
"Without resorting to such tortures as were used by the US CIA, we have means to prove that this incident has nothing to do with us ", he was quoted as saying by Pyongyang's official Korean Central News Agency (KCNA).
