Attack on Hiroshima and Nagasaki
On August 6, 1945, during World War II (1939-45), an American B-29 bomber dropped the world’s first atomic bomb over Hiroshima in Japan. The explosion wiped out 90% of the city and killed 80,000 people; tens of thousands more would later die due to the exposure to radiation. Three days later, a second B-29 dropped another A-bomb on Nagasaki, killing about 40,000 civilians. Japan’s Emperor Hirohito announced Japan’s surrender in World War II over the radio on August 15. It took such devastating actions to finally push Japan into surrendering.
