WASHINGTON (AP): The mayor of Hiroshima is praising President Barack Obama’s plan to visit as a “bold decision based on conscience and rationality.”

The White House announced this morning that Obama will become the first sitting American president to visit the city where the U.S. dropped an atomic bomb. He will visit the site later this month with Japanese Prime Minister Shinzo Abe during a previously scheduled trip to Japan.

Obama’s visit will bolster his call for denuclearization and honor victims of the bombing that killed 140,000 Japanese on Aug. 6, 1945.

The White House has ruled out the possibility that Obama will apologize for the bombing of Hiroshima.
