Iran away from enough material for nuclear bomb

 Iran is now just a year away from having enough material for a nuclear bomb, a former head of U.N. nuclear inspections Olli Heinonen said.

According to Reuters, however, Olli Heinonen wrote in an article that building a stock of some 250 kg of 20-percent enriched uranium - a form that could within weeks be further purified to the 90-percent weapons grade - did not automatically mean Iran could deploy a bomb without further engineering work.
