Tensions are rising on the Korean Peninsula after the United Nations OK'd new sanctions against North Korea. All 15 members of the U.N. Security Council agreed to the new sanctions. Even North Korea's friends China and Russia said yes. The sanctions are because of N. Korea's third nuclear missile test, which they carried out in February. China's Xinhua news agency said: "The new sanctions make it more difficult for Pyongyang to finance and [get] material for [nuclear missile] programs." The U.N. also said it would search ships coming in and out of N. Korea. U.S. ambassador to the U.N. Susan Rice warned that the U.N. would "take further significant actions" if Pyongyang carried out another nuclear test.

North Korea has hit back against the sanctions. It says it is ending all non-aggression agreements with S. Korea. It will also close its hotline with Seoul and its border-crossing point between the two countries. Pyongyang also warned it would consider attacking its enemies with nuclear weapons. South Korea immediately informed the North not to take any military action. Major-General Kim Yong-hyun said South Korea's "military will strongly and sternly punish" any North Korean attacks. A military spokesperson warned: If Seoul comes under attack, the top levels of North Korea's regime including leader Kim Jong-un could become targets." The White House said the U.S.A. could stop any North Korean missile attack.
