Seventy years after the atomic bombings of Hiroshima and Nagasaki, Red Cross hospitals are still treating thousands of survivors and identifying new links between radiation exposure and fatal illnesses.
WARNING: SOME OF THESE IMAGES COULD BE DISTRESSING.
Many of today's nuclear bombs are ten times more powerful than the ones dropped 70 years ago and the destruction and human suffering they could cause is unimaginable.
The commemoration of the dropping of the bombs comes just months after the Review Conference of the Treaty on the Non-Proliferation of Nuclear Weapons failed to agree a move forward towards their elimination.
