Doubts over Iran nuclear capacity

BBC

Doubts have been raised about how technically advanced Iran's nuclear programme is, after it emerged Tehran may have used material from China.

Western diplomatic sources told the BBC the feedstock for Iran's recent uranium enrichment experiments probably came from materials supplied in 1991.

That was before China joined the Non-Proliferation Treaty, and before it was bound by its export controls.

Iran recently announced it had enriched uranium in its possession.
