8.15 am. The precise time 65-years ago when an atomic bomb was dropped by the United States on Japan.
Tens of thousands of people turned out in Hiroshima to mark the event and pay homage to its victims.
Among them, for the first time, a United States representative.
The UN’s Secretary General, Ban Ki-moon, called for all nuclear weapons to be abolished.
“As long as these weapons exist we will live under a nuclear shadow and that is why I have made nuclear disarmament and non-proliferation a top priority for the United Nations,” he said.
The attack killed at least 140,000. Thousands more died later of illness and injuries.
Three days afterwards came a second atomic bomb on Nagasaki, prompting Japan’s surrender.
