WASHINGTON, Aug 11 (OneWorld.net) - Marking the 64th anniversary of the U.S. nuclear attacks on Hiroshima and Nagasaki that killed over 100,000 civilians, a disarmament group celebrated a day of peace last week. The annual Sadako Peace Day ceremony was inspired by a young girl who died from leukemia as a result of the atomic bomb that hit Hiroshima in 1945.
