North Korea threatens to hit back at White House in hacking row.
North Korea threatened to hit back at the White House and other US targets if Washington sanctions it for an alleged hacking attack.
The country's top military body, the National Defence Commission, again denied involvement in the hacking of Sony Pictures, which prompted executives to halt the release of a film seen by Pyongyang as mocking the North's leader.
US President Barack Obama said it was confirmed that the North carried out the hacking.
The North's NDC, in a statement on the official news agency, said its army and people "are fully ready to stand in confrontation with the US in all war spaces including cyber warfare space to blow up those citadels".
