Japan on Sunday marked 72 years since the world's first nuclear attack on Hiroshima, with the nation's traditional contradictions over atomic weapons again coming into focus.

The Asian country suffered two nuclear attacks at the end of the World War II by the United States -- in Hiroshima on August 6, 1945 and in Nagasaki three days later.

The bombings claimed the lives of 140,000 people in Hiroshima and 74,000 people in Nagasaki.

Some died immediately while others succumbed to injuries or radiation-related illnesses weeks, months and years later.
