U.S. slaps new sanctions on North Korea after Sony hack

The United States is hitting North Korea with a new set of economic sanctions after determining the country was behind last month's computer hack at Sony.
The White House said a new executive order targets leaders in North Korea's government, preventing them from accessing property and entering the United States. The isolated nuclear regime, which has denied involvement in the Sony hack, was already subject to a strict set of U.S. economic restrictions.
