U.N. Security Council Hits North Korea With More Sanctions After Nuclear Test

The U.N. Security Council agreed to tighten sanctions against North Korea on Thursday as punishment for its recent nuclear test. The Council's unanimous agreement came after three weeks of negotiation between the U.S. and China, which has opposed such measures in the past. North Korea was furious at the U.N. action, issuing a threat to attack the U.S. with nuclear weapons as the sanctions came up for a vote.
