Iran has handed over to the UN's nuclear watchdog a blueprint long sought by inspectors, which shows how to mould uranium metal into spheres for nuclear warheads.
 
The handover came ahead of an International Atomic Energy Agency report due this week, which could lead to a third round of UN sanctions against Tehran.

Some diplomats said the IAEA report due this week was likely to say Iran has improved co-operation with a long-running inquiry into its nuclear programme.

 

The timing and toughness of any further UN sanctions against Iran will hinge on world powers' interpretation of the report and a parallel report by Javier Solana, the EU's chief diplomat, on recent dialogue with Tehran.

Solana is expected to confirm that Iran remains unwilling to suspend uranium enrichment, which it says is to generate electricity but Western leaders claim is to make atom bombs.
