Operation Gomorrah (aka the Battle of Hamburg or Hamburg Air Offensive) was a sustained area bombing campaign of the German port of Hamburg in four night attacks by the Royal Air Force and two daytime attacks by the United States Air Force in July and August 1943. Over 3,000 bombers created a firestorm, which resulted in 46,000 civilian deaths, one of the worst civilian disasters of the Second World War (1939-45).
Update: Hamburg's Police denies any knowledge of the incident claiming it is fake news, yet the Jordanian Ministry Of Forgein Affairs And Expatriates stated that they are following the investigations with German authorities and arranging for transporting the body back to Jordan.
