WASHINGTON (Reuters) - U.S. Ambassador to the United Nations Nikki Haley said on Tuesday that North Korea s launch of a missile over Japan was  absolutely unacceptable and irresponsible  and that the Security Council now needed to take serious action.  No country should have missiles flying over them like those 130 million people in Japan. It s unacceptable,  Haley told reporters. North Korea has  violated every single U.N. Security Council resolution that we ve had and so I think something serious has to happen,  she added. Saying  enough is enough,  Haley said she hoped China and Russia would continue to work with the rest of the U.N. Security Council when it meets on Tuesday afternoon to discuss what more can be done about North Korea s nuclear and missile programs.
