Iran produced 17 kgs of further enriched uranium
None
Iran's nuclear chief said Wednesday his country has produced 17 kilograms of uranium enriched to 20 percent, defying UN demands to halt the controversial program.
The 20 percent level, needed to produce fuel for a medical research reactor, is far below the more than 90 percent required to build a nuclear weapon, but US officials have expressed concern Iran may be moving closer to the ability to reach weapons-grade level. (AP)
