(Reuters) - Here is a look at recent incidents involving North Korea and international efforts to stop the communist state's nuclear and missiles programs that have led to rising tensions on the Korean peninsula.
April 5, 2009 - North Korea launches missile carrying a satellite over the Sea of Japan. The test fails to make orbit, but prompts unanimous condemnation by the U.N. Security Council as a violation of sanctions barring the use of ballistic missile technology. Nine days later, North Korea condemns the U.N. Security Council statement and withdraws from the "Six Party Talks" meant to rein in its nuclear program. It also announces its intention to reactivate its nuclear facilities.
