The United States, South Korea and Japan on Wednesday announced the launch of a new multinational team to monitor the enforcement of sanctions against North Korea after Russia and China thwarted monitoring activities at the United Nations.

North Korea confirmed Thursday that its recently revised constitution defines South Korea as “a hostile state" for the first time, two days after it blew up front-line road and rail links that once connected the country with the South.

The North Korean Constitution now defines South Korea as a "hostile state," state-run media said Thursday, in the first indication of changes made during a parliamentary meeting last week.
