Iran is capable of producing three nuclear bombs

Citing the secret report of the International Atomic Energy Agency (IAEA), the Reuters agency reported that Iran already has 128.3 kg of uranium, enriched to 60%. 

According to some estimates, about 42 kg of this 90%-enriched material is theoretically enough to create an atomic bomb.

Thus, Iran's uranium reserves, which are subject to further enrichment, are sufficient to create three atomic bombs.
