U.S. Envoy Caroline Kennedy Visits Nagasaki 

W300

U.S. Ambassador Caroline Kennedy has visited the Japanese city of Nagasaki, site of the Aug. 9, 1945, American atomic bomb attack that killed 70,000 people and helped prompt Japan's surrender in World War II.

The daughter of U.S. President John F. Kennedy toured Nagasaki's Atomic Bomb Museum on Tuesday and met with some atomic bomb survivors. At the city's Peace Park she was to help plant an American dogwood tree, one of 3,000 offered as a gift of friendship to Japan.

In 1978, Kennedy visited Hiroshima, site of the first U.S. bomb attack, on Aug. 6, 1945, with her uncle, Sen. Edward Kennedy long before President Barack Obama tapped her to become U.S. ambassador in Tokyo. The Hiroshima attack killed 140,000 people.

Kennedy is wrapping up a busy first month on the job that also took her to an American military base and northeastern cities devastated by the March 2011 earthquake and tsunami.
