FILE - In this April 5, 2009 image made from KRT video, a rocket is lifted off from its launch pad in Musudan-ri, North Korea. As international tensions rise over a planned North Korean rocket launch, the U.N. nuclear agency is taking a wait and see attitude on an offer from the North to allow agency experts back into the country, according to a letter shared Tuesday, April 3, 2012 with The Associated Press. In the March 30 letter, circulated internally among the International Atomic Energy Agency's 35 member nations, IAEA head Yukiya Amano expresses thanks for the March 16 overture by North Korean Atomic Energy head Ri Je Son and says "the IAEA will follow up on your invitation in a constructive spirit."
