The United States has imposed financial sanctions on North Korea and several senior government officials in retaliation for cyber attacks, including on Hollywood studio Sony Pictures.
The White House said, US president Barack Obama signed on additional sanctions on three North Korean organisations and 10 individuals.
The President’s executive order says, sanctions are a response to the government of North Korea’s provocative, destabilising and repressive actions and policies, particularly, its destructive and coercive cyber-related actions.
