World War II era bomb explodes in UK. This is what happened

On 6th August 1945, a US bomber dropped the uranium fission bomb, codenamed Little Boy, on Hiroshima. Three days later it dropped another bomb codenamed Fat Man, on Nagasaki.

At 11:02 a.m., the moment the B-29 bomber dropped a plutonium bomb, Nagasaki survivors and other participants in the ceremony stood in a minute of silence to honor more than 70,000 lives lost.

Two developments this year provide grounds for hope, said UN Secretary-General António Guterres, in the form of the reaffirmation from the US and Russia, “that a nuclear war cannot be won and must never be fought”, together with a commitment to engage in arms control talks.

Secondly, said Guterres in his message, the Treaty on the Prohibition of Nuclear Weapons has now come into force, representing “the legitimate fears of many States, about the existential danger posed by nuclear weapons.”

The global Treaty on the Prohibition of Nuclear Weapons took effect in January after years of civil effort joined by the atomic bombing survivors, or hibakusha. But while more than 50 countries have ratified it, the treaty notably lacks the US and other nuclear powers as well as Japan, which has relied on the U.S. nuclear umbrella for its defense since the war's end.
