The U.N. Security Council has voted unanimously for tough new sanctions to punish North Korea for its latest nuclear test, a move that sparked a furious Pyongyang to threaten a nuclear strike against the United States.

The vote Thursday by the U.N.’s most powerful body on a resolution drafted by North Korea’s closest ally, China, and the United States sends a powerful message to North Korea that the international community condemns its ballistic missile and nuclear tests — and its repeated violation of Security Council resolutions.

The new sanctions are aimed at making it more difficult for North Korea to finance and obtain material for its weapons programs.
