Explanation:

• Hiroshima Day takes place every year on August 6 to commemorate the day in August 1945 when an atomic bomb was dropped on the Japanese city of Hiroshima on August 6 by United States, followed a few days later by another drop on the city of Nagasaki on August 9.
• Although these bombings effectively ended World War II, the two cities were terribly destroyed and casualties were estimated at around 200,000, mostly civilians.
• This was the first time in the history of warfare when a nuclear bomb was used against a nation.
