Graph suggests Iran working on bomb

Iranian scientists have run computer simulations for a nuclear weapon that would produce more than triple the explosive force of the World War II bomb that destroyed Hiroshima, according to a diagram obtained by The Associated Press.

The bomb that the United States dropped on Hiroshima in Japan during World War II, in comparison, had a force of about 15 kilotons. Modern nuclear weapons have yields hundreds of times higher than that.

The diagram has a caption in Farsi: "Changes in output and in energy released as a function of time through power pulse." The number "5'' is part of the title, suggesting it is part of a series.
