HIROSHIMA, JAPAN - AUGUST 06: Candles in paper lanterns float in the Motoyasu River in front of the Atomic Bomb Dome at the Peace Memorial Park, in memory of bomb victims during a commemoration of the 64th anniversary of the Hiroshima bomb on August 6, 2009 in Hiroshima, Japan. The bomb dropped by the U.S. killed an estimated 70,000 people instantly, with many thousands more dying over the following years from the effects of radiation. Three days after the first bomb was dropped on Hiroshima, another atomic bomb was dropped on Nagasaki, ending World War II.
